## Introduction

This is a short manual on the Building Regulations, providing guidance on the Building Regulations system in England. Volume 1 of this manual gives a very high-level outline of how the Building Regulations system currently works. Volume 2 goes into more detail. The manual is only a summary. You should always rely on what is said in the legislation, rather than the guidance in this manual. You should think about what help you need with your project. There are professionals who can give you advice on your project. This can help you make sure that you comply with the Building Regulations. When you do one of the following, Building Regulations are likely to apply:

a.	 put up a new building b.	 change or make bigger a building that is already built c.	 change the use of a building that is already built or d.	 alter the building services if they are either what is legally called:
i.	
a 'controlled service' or
ii.	
a 'controlled fitting' (these terms are explained in Appendix I). 
The Building Regulations may apply in and around buildings. These requirements are intended to protect people's safety, health and welfare. They also set standards for accessibility, water use, energy use and security. The approved documents give further guidance for many common building situations. They contain statutory guidance on how to meet the requirements of the Building Regulations. Dame Judith Hackitt led the Independent Review of Building Regulations and Fire Safety following the Grenfell Tower tragedy. Dame Judith's expert group called for this manual to be revised and made available. The Building Act 1984 set up a simple way of regulating building in England (and, at the time, in Wales). This new system was explained by a manual, the Manual to the Building Regulations. The old manual is now out of date. This current manual replaces previous manuals in England. In the coming months, the government intends to introduce legislation to deliver a new Building Safety Regulator. The new regulator will be responsible for implementing and enforcing a more stringent regulatory regime for higher-risk residential buildings (HRRBs) (a term defined by the Independent Review). The new regulator will also provide wider and stronger oversight of safety and performance across all buildings.

The Fire Safety Bill, recently introduced by the government, and associated regulatory changes will enable delivery of the recommendations from the Independent Review. The Bill places beyond doubt that external wall systems, including cladding, and the fire doors to individual flats in multi-occupied residential blocks fall within the scope of the Regulatory Reform (Fire Safety) Order 2005. These changes will affirm fire and rescue services' ability to enforce locally against building owners or managers who have not remediated unsafe aluminium composite material (ACM) cladding from multi-occupied residential buildings. 

This manual is split into two parts: 

a.	 Volume 1 is an overview of the Building Regulations system. It is written to give a simple 
overview of how the system works. 
b.	 Volume 2 gives more detailed guidance. It is written for people working in the 
construction industry.
You will need to know when Building Regulations apply. Before you start to plan a project, you should seek professional advice. This manual is not intended to provide legal, construction, design or planning advice. It is the duty of anyone responsible for building work to understand and meet their legal obligations. There will be changes to the legislation and guidance summarised in this manual. You should check whether you are reading the most up-to-date version. The key terms are highlighted in blue and listed in Appendix I. A list of references is given in Appendix II. 

## Manual To The Building Regulations Volume 1: Overview Chapter 1 The Regulatory Framework The Building Regulations

The Building Act 1984 (the Building Act) is the most wide-reaching law controlling building in England. It sets the enforcement powers. The Building Regulations 2010 (the Building Regulations) go into more detail about building work. Most building work carried out in England must comply with the Building Regulations. The legal term 'building work' generally includes building new buildings, making buildings bigger, altering buildings and changing what they are used for. It also covers installing a 'controlled service' or a 'controlled fitting'. A replacement window is an example of a controlled fitting. A boiler is an example of a controlled service. 'Renovation of thermal elements' is also building work. This includes roofs or external walls. 

Those responsible for carrying out building work have a duty to meet the requirements of the Building Regulations. Generally, the Building Regulations set out the required standards for the building work. For example, a home must be insulated, but the Building Regulations do not tell you how you should do it. The approved documents give help for some common problems.

There are 15 technical requirements in Schedule 1 to the Building Regulations. Each technical requirement corresponds to a letter - for example, Part B is fire safety. These set out some of the legal requirements of the Building Regulations - these are rules that must be followed. They are often referred to as technical requirements. In addition to these, there are some other requirements in the Building Regulations. Some of these are about keeping energy use low. 

The people planning the work can decide how best to meet the rules, and there is guidance to help them (see the next section on approved documents). Everyone involved in carrying out building work must obey the rules. That includes: the building owner, agents, designers, builders and installers. The Building Regulations also allow inspections and enforcement to take place. Building control bodies or building inspectors will need to be satisfied too. Building control bodies is the term used for the organisations which check or inspect building work.

## Approved Documents

The Building Act allows the government to publish approved documents. The government may also approve other guidance. The approved documents give more detailed advice on how to meet the legal requirements of the Building Regulations for some common situations. 

The approved documents should be useful for most domestic projects. The approved documents may not be relevant for all situations. Limitations on using the approved documents are discussed in Chapter 7 of this volume and Chapter F in Volume 2. You do not have to follow the guidance in approved documents, but if you don't you need to be sure that your building work meets the legal rules.

Following the approved documents does not always guarantee that you are complying with the Building Regulations. A list of the approved documents is set out in Table 1.1. When working on a building that is already there, you should agree with the building control body the approach to standards.

NOTES:
1. The requirements that apply to material changes of use are covered in Table A2 in Volume 2. 2. Approved Document P provides guidance for other buildings if the supply is shared with a dwelling.

## Following Other Guidance

It is important to agree with the building control body that the standards you are using are right for your project. If you are undertaking a project that needs to be checked by others, you should make sure you are designing to the right standards. Any work that the Building Regulations apply to must meet all requirements in Schedule 1 which are relevant to the project. For example, new electrical wiring must comply with Part P (electrical safety), Part L (energy efficiency) and Part M (access to and use of buildings). It also must comply with the fire safety requirements of Part B. The materials and workmanship must meet Regulation 7 of the Building Regulations. A list of other laws that often govern buildings or building work is given at the end of this document (in Appendix II). The legal requirements of the Building Regulations must always be met when they apply to your project. Although the local authority has some powers to relax Building Regulations you should take your own legal advice if you don't think you can comply with every part of the Building Regulations. This applies to all those responsible for building work. This includes: the building owner, agents, designers, builders and installers. Meeting the requirements of the Building Regulations can be complex. For example, it is a good idea that those designing or carrying out work are skilled in designing and constructing buildings. It may be necessary to seek advice. The more complex your project, the more expert help you are likely to need.

## Volume 1 Chapter 2 The Building Control Process

The building control process involves building inspectors approving some aspects of the building work. Three laws control this process in England. These are the Building Act 1984 (Building Act), the Building Regulations 2010 (Building Regulations) and the Building 
(Approved Inspectors etc.) Regulations 2010 (Approved Inspectors Regulations). 

There are several paths through the building control process. 

a.	 The work may be checked by a building control body, either: 
i.	
local authority building control or 
ii.	
a licensed approved inspector.
b.	 Some types of work may be done by a 'competent person'. This is a term for an installer 
who works under a scheme that has been approved by the government. 
The flowchart in Figure 2.1 provides a simplified overview of the building control process for those involved in building work. 

Start
No
Do Building Regulations apply to the work?   
Yes
No
Has the work commenced?
The work may be checked by the local authority or an approved inspector or carried out by a competent person
Yes
Apply to the local authority
No
Is all the building work covered by a competent person scheme or a third-party scheme for certification? No need to submit a notice to the local authority. The competent person or the 
scheme operator will notify the local authority of the work and provide them and the building occupier with a certificate of completion within 30 days of completion of the work
The work may be checked by the local authority or an approved inspector. Work 
covered by a competent person scheme or a third-party scheme for certification can take place at the same time

Does the work involve any of the following: 1. Erecting or working on a building where the Regulatory Reform 
(Fire Safety) Order 2005 applies or will apply after the work is complete?
2. Erecting a building that fronts a private street? 3. Erecting a building over a sewer?
Yes
No
No
The applicant must 
deposit a full plans application
The applicant may deposit a building notice application - additional plans and details may be requested by the local authority
The local authority must provide a substantive assessment of 
the plans and details and must approve or reject plans within 
five weeks or two months (with agreement). The local authority 
must consult with the fire authority and, where appropriate, 
the sewerage undertaker and consider their views
Work may start after the local authority has had at least two clear working days' notice. If the full plans application or submitted details under a building notice have not been assessed and approved, the work will be deemed 'at risk'

The local authority will provide an inspection framework and must be notified at these certain stages in order for inspection to take place. Where the local authority is satisfied that work complies with the Building Regulations, it will issue a completion certificate

NOTES:
1. The approved inspector must issue a final certificate within four weeks of occupation for buildings other than dwellings or 
eight weeks for dwellings. Regulation 17(7) of the Approved Inspectors Regulations allows a local authority to extend these 
time periods either before or after expiry. 
Refer to Volume 2, Chapter E for details of approved inspectors' initial notices.

More information on the building control process can be found in Volume 2, Chapter A. 

No notification required 
Yes
Approved inspectors under the Building (Approved 
Inspectors etc.) Regulations 2010 In conjunction with the approved inspector an initial notice must be given to the local authority
Is initial notice accepted by the local authority?
Provide additional information, amend notice or submit application to local authority
Yes
Request plan assessment and plans certificate, if 
desired. Where applicable, plans certificate is issued 
to both client and local authority Agree site inspection plan with approved inspector
The approved inspector must consult the fire 
authority and, where appropriate, the sewerage undertaker, taking due regard of their views. The plans certificate or final certificate cannot be issued until 15 working days have elapsed

Where the approved inspector is satisfied that work 
complies with the Building Regulations, it will issue a 
final certificate to both the applicant and the local 
authority within eight weeks of completion1

## Volume 1 Chapter 3 Do I Need To Notify Someone?

If you are going to carry out building work that is controlled under the Building Regulations then you need to notify or get approval from a building control body before you start the work. This does not apply to work which is carried out under a competent person scheme.

Building Regulations approval is different to planning permission and listed building consent. 

You could need all three. To find out if your project will need planning consents, contact your local planning authority. If you are carrying out work under planning 'permitted development' rights, you are likely to need to go through the building control process. Even if your building project follows your planning permission, you must still meet the requirements of the Building Regulations. You must check if the work you are about to carry out is controlled under the Building Regulations before you start work. You can ask a building control body whether the Building Regulations apply to your project. A building control body can be either your local authority building control service or an approved inspector. Regulation 3 of the Building Regulations sets out the meaning of the term building work. Building work is controlled by the Building Regulations. In summary, when you do one of the following, Building Regulations are likely to apply:

a.	 put up a new building
b.	 change or make bigger a building that is already built c.	 change the use of a building that is already built or d.	 alter the building services if they are either what is legally called:
i.	
a 'controlled service' or
ii.	
a 'controlled fitting' (these terms are explained in Appendix I). 
You may also need Building Regulations approval for many other things, such as:

a.	 replacing consumer units or installing new electric circuits b.	 installing new plumbing and waste connections c.	 changing existing electric circuits near a bath or shower d.	 putting in a ventilation or air-conditioning system e.	 replacing windows and doors f.	 replacing roof coverings on pitched and flat roofs g.	 putting in or replacing a heating system h.	 adding extra radiators 
i.	 removing a chimney breast j.	 removing a wall (load bearing and sometimes non-load bearing) k.	 creating a through lounge. 
Local authority building control or an approved inspector can advise on whether the Building Regulations apply. Some work does not have to be checked by a building control body but must still comply with the Building Regulations. An example is putting in new loft insulation (unconnected to a material change of use or other building work). In all cases, seek advice from a building control body to see if the Building Regulations apply. Combustion installations, such as gas boilers, must be installed to comply with the Gas Safety (Installation and Use) Regulations 1998 (subsequently referred to as the Gas Safety Regulations) and the Building Regulations. Gas installations, such as a gas cooker, must also comply with the Gas Safety Regulations and the Building Regulations. The Gas Safety Regulations require that people who work on gas systems must be registered as competent. This means that they must be on the Gas Safe Register. This is a list of competent persons who may install, service or repair gas appliances or fittings. You can check the list at the following website: https://www.gassaferegister.co.uk/ The Gas Safety Regulations cover the installation, maintenance and use of gas fittings, appliances and flues. 

## Summary

You might need approval, or be required to follow certain rules, for works not listed here. Check with your local authority building control service or an approved inspector to decide whether you need approval. You do not need Building Regulations approval for the following: 

a.	 Work that is not covered by the Building Regulations. 
b.	 Work carried out by someone who is registered with a competent person scheme where 
the type of work is within the scope of the scheme.
c.	 You do not need advance approval for emergency repairs to your boiler or heating 
system, but you must comply with the Gas Safety Regulations.

## What Happens To Those Who Don'T Comply With The Building Regulations?

Where building work is carried out without asking for Building Regulations approval, the owner or the person doing the work may be taken to court. Local authorities can take action when building work does not comply with the Building Regulations or when buildings are unsafe. The local authority can take action against the building owner or those doing the building work. You may be made to pay for faulty work to be fixed. The courts can impose unlimited fines. Without approval the building owner will not have certificates of compliance, which they may need when selling or insuring their home. See Volume 2, Chapter A, for more details on when the Building Regulations apply. You can also check with your local authority building control service or an approved inspector.

## Volume 1 Chapter 4 Is A Building Control Body Involved?

When Building Regulations apply to the work you want to do, then you need either to: 

a.	 involve a building control body - either local authority building control or an approved 
inspector - or
b.	 use an installer registered under a competent person scheme to do the work.
If you need to involve a building control body, you will need to notify them of your building work. You will then need to seek their approval and explain how your work will meet the requirements of the Building Regulations. They will provide advice and carry out some checks. For some types of work you can use a competent person scheme. Examples include mechanical ventilation systems, electrical work and home window replacement. This means that you do not have to get the building control body to check the work done under the competent person scheme. Installers registered with a competent person scheme must follow certain rules to make sure they comply with the Building Regulations. They must issue a certificate to show that they have complied. You can use both a building control body and a competent person scheme on the same project. 

## Volume 1 Using A Building Control Body

If the work has started or been completed and you have not notified a building control body then you cannot use an approved inspector. You can only use your local authority building control service to approve your work. Local authority building control are not obliged to approve work that has already been carried out. It is a good idea to seek approval before starting your work. This may avoid you being asked to change or demolish your work later. Where building work does not comply with the Building Regulations, the person who did the work may be taken to court. To make it easier for people who wish to have work approved which has already been started or finished, there is a process called 'regularisation'. The local authority will try to determine whether the works meet the Building Regulations. The reason for doing this is to get a 'certificate of regularisation' for your works. This may mean that you have to open up works. You could be asked to take down or rebuild work. You should discuss your project with your local authority building control service before making a 'regularisation application'. You will be charged for this service. For further information on the process, see Volume 2, Chapter B, paragraphs B13 to B17.

You can learn more about when to use a building control body in Volume 2, Chapter B.

## Chapter 5 Competent Person Schemes

Competent person schemes let tradespeople show that they can do certain works. 

Examples include home window replacements or gas boiler installations. You do not need to apply for Building Regulations approval for work completed by an installer who is working under a competent person scheme.

## Volume 1 Volume 1

Only installers who are registered with a competent person scheme can self-certify that their work complies with the Building Regulations. Where necessary, they will tell your local authority about the work for you. You will receive a certificate from them within 30 days of completion of the work. This will confirm that the work complies with the Building Regulations. This certificate will also show up in property searches if you sell your home. If you don't receive a certificate within 30 days of completion, the competent person scheme operator that your installer is registered with should be able to help. You can learn more about competent person schemes in Volume 2, Chapter C.

## Chapter 6 Local Authority Building Control And Approved Inspectors

There are two types of building control body. These are:

a.	 local authority building control b.	 approved inspectors. 
It is up to you which you use if your work has not started. If it has started, you must use local authority building control.

## Local Authority Building Control

If you apply for approval for your project from your local authority, then the process will broadly follow this route:

Local authority route

Local authority building control under the Building Regulations 
2010

Does the work involve any of the following: 1. Erecting or working on a building where the Regulatory Reform 
(Fire Safety) Order 2005 applies or will apply after the work is complete?
2. Erecting a building that fronts a private street?
3. Erecting a building over a sewer?
Yes
No
The applicant must 
deposit a full plans application
The applicant may deposit a building notice application - additional plans and details may be requested by the local authority

The local authority must provide a substantive assessment of the plans and details and must approve or reject plans within five weeks or two months (with agreement). The local authority must consult with the fire authority and, where appropriate, the sewerage undertaker and consider their views Work may start after the local authority has had at least two clear working days' notice. If the full plans application or submitted details under a building notice have not been assessed and approved, the work will be deemed 'at risk' The local authority will provide an inspection framework and must be notified at these certain stages in order for inspection to take place. Where the local authority is satisfied that work complies with the Building Regulations, it will issue a completion certificate

## Volume 1 Volume 1 Approved Inspectors

You can apply for approval for your project through a licensed approved inspector. Approved inspectors are independent of your local authority. An approved inspector will inform your local authority of the work by giving an initial notice. The Building (Approved Inspectors etc.) Regulations 2010 (Approved Inspectors Regulations) 
are the main law governing approved inspectors. If you use an approved inspector then the process will broadly follow this route:

Approved inspector route
Approved inspectors under the Building (Approved 
Inspectors etc.) Regulations 2010
In conjunction with the approved inspector an initial notice must be given to the local authority
Is initial notice accepted by the local authority?
No
Provide additional information, amend notice or submit application to local authority
Yes
Request plan assessment and plans certificate, if desired. Where applicable, plans certificate is issued to both client and local authority

When the person carrying out the building work engages an approved inspector, together the person and the approved inspector must give the local authority both of the following:

a. an initial notice
Agree site inspection plan with approved inspector
b. an insurance declaration demonstrating that the approved 
inspector has the appropriate professional and public liability insurance.

The content of an initial notice is outlined in Form 1 in Schedule 1 to the Approved Inspectors Regulations. The initial notice must contain all of the following information:

a. a description of the work
b. in the case of a new building or extension:
The approved inspector must consult the fire 
authority and, where appropriate, the sewerage undertaker, taking due regard of their views. The plans certificate or final certificate cannot be issued until 15 working days have elapsed
i. a site plan to a scale of not less than 1:1250 showing the 
boundaries and location of the site
Where the approved inspector is satisfied that work complies with the Building Regulations, it will issue a final certificate to both the applicant and the local authority within eight weeks of completion1
ii. a statement that if work involves building over or near any 
drain, sewer or disposal main shown on any map of sewers kept by the sewerage undertaker, the approved inspector will consult the sewerage undertaker.

## Notes: 1. The Approved Inspector Must Issue A Final Certificate Within Four Weeks Of Occupation For Buildings Other Than Dwellings Or

eight weeks for dwellings. Regulation 17(7) of the Approved Inspectors Regulations allows a local authority to extend these time periods either before or after expiry. 
You can learn more about these two types of building control body and their role in checking that building work complies with the Building Regulations later in this manual. Chapter D in Volume 2 covers local authority building control and Chapter E looks at approved inspectors.

## Volume 1 Chapter 7 Meeting The Technical Requirements Complying With The Building Regulations

The key legal requirements which your building work must meet in order to comply with the Building Regulations are frequently referred to as the 'technical requirements'. The technical requirements are set out in Schedule 1 to the Building Regulations and the areas addressed in the requirements are summarised in Table 7.1 below.

NOTE: The Building Regulations, including Regulation 7, also apply.

In addition to complying with the technical requirements in Schedule 1 to the Building Regulations, work controlled by the Building Regulations must be carried out with adequate and proper materials and in a workmanlike manner, as required by Regulation 7 of the Building Regulations. Further details are given in Chapter F in Volume 2. 

The visual quality of building work is only controlled by the Building Regulations if it affects technical compliance with the Building Regulations. This means that the quality of pointing of brickwork is only important if it affects, for example, the structural stability of the wall or another requirement regarding work controlled by the Building Regulations. Building Regulations ban the use of combustible materials in the external walls of certain tall residential buildings. For further information, see Approved Document B, Volume 1: Dwellings.

## How To Use The Technical Guidance

While the legal requirements are contained in the Building Regulations (summarised above), the approved documents contain guidance on how you may be able to meet those legal requirements. The approved documents provide guidance for common building situations. They may not provide appropriate guidance if the case is unusual in terms of its design, setting, use, scale or technology. Non-standard conditions may include any of the following: 

a.	 difficult ground conditions b.	 buildings with unusual occupancies or high levels of complexity c.	 very large or very tall buildings d.	 large timber buildings e.	 some buildings that incorporate modern construction methods. 
The full list of the approved documents and what they cover is given in Table 1.1 in Chapter 1. The approved documents will be relevant in many common building situations. Anyone using the approved documents should have sufficient knowledge and skills to understand the guidance and correctly apply it to the building work. This is important because simply following the guidance does not guarantee that your building work will comply with the legal requirements of the Building Regulations. Each approved document contains legal requirements (which you must follow) and guidance 
(which you may or may not choose to follow). The text in a box with a green background 

at the beginning of each section of an approved document is taken from the Building Regulations. This text sets out the legal requirements. The explanation which follows the legal requirements is guidance (Figure 7.1). The guidance then explains one or more ways to demonstrate how building work should comply with the legal requirements in common circumstances. The terms in green lettering in an approved document are key terms, listed and explained in the appendix to that approved document.

Guidance in the approved documents addresses most, but not all, situations that homeowners will face. Situations may arise that are not covered. You or your advisers will need to carefully consider whether following the guidance will mean that the requirements of the Building Regulations will be met. 

## K4 Requirement K4: Protection Against Impact With Glazing

This approved document deals with the following requirement from Part K of Schedule 1 to the Building Regulations 2010.

## ➊ Performance

In the Secretary of State's view, you can meet requirement K4 if you adopt, in critical locations, one of the following approaches. 

## ➋

a. Measures to limit the risk of cutting and piercing injuries by the use of glazing that is reasonably
safe, such that, if breakage did occur, any particles would be relatively harmless.
b. Use of glazing sufficiently robust to ensure that the risk of breakage is low.
c. Steps are taken to limit the risk of contact with the glazing.
Key 
➊The law: extract from Schedule 1 to the Building Regulations 2010. ➋Statutory guidance.

Where the approved documents do not provide appropriate guidance, there may be other ways to demonstrate compliance. It may be possible to achieve compliance by following the advice in one or more of the sources set out below:

a.	 guidance from recognised standards bodies b.	 industry recognised codes c.	 manufacturers' technical literature. 
Where you wish to follow an alternative approach to the guidance in the approved documents, you should discuss and agree it with a building control body before starting building work. British and European standards and other technical guidance also deal with matters that are not covered by the Building Regulations. Nothing in the Building Regulations or an approved document prevents you from adopting higher standards. Building work must meet the relevant technical requirements in the Building Regulations. Regulation 7 of the Building Regulations requires building work to be carried out 'with adequate and proper materials' and 'in a workmanlike manner'. Regulation 7 also controls the combustibility of external walls of certain tall buildings. For further information, see Approved Document B, Volume 1: Dwellings.

## Responsibility For Compliance

Receiving a completion certificate or final certificate is not a complete guarantee of compliance with the Building Regulations. The legal meaning of the certificate is that it is 'evidence but not conclusive evidence' of compliance. The building control officer or approved inspector will not have checked every piece of building material and how it has been fitted or every aspect of submitted documents. It is the responsibility of those carrying out building work to comply with the Building Regulations. The building control body will inspect the work on site at appropriate stages, but you cannot rely on this as the only method of ensuring that the work complies with the Building Regulations. The responsibility for ensuring compliance rests with the people carrying out the work. For example, a building has just received the final certificate or completion certificate, but the roof is leaking. The fact that the roof leaks is the builder's or building designer's problem and not the building control body's problem. However, the building control body may point out problems either with the design or construction at any stage up to granting the final certificate or completion certificate.  

## Planning Building Work

By carefully planning building work in advance, you can avoid many potential problems. Homeowners in particular may wish to engage building design professionals to help guide them through the complexities of construction projects. Design professionals can produce coordinated drawings and other design information to reduce risks once you start to build. The people who design buildings should be suitably competent and skilled in order to satisfy the requirements of Schedule 1 to the Building Regulations. 

If you carry out your building work without first ensuring that it will comply with Building Regulations, you may later be required to undo or redo it, and this may be expensive. You can learn more about the approved documents and Regulation 7 of the Building Regulations in Volume 2, Chapter F.

## Constructing And Altering Buildings

The people who construct and alter buildings should be suitably competent and skilled in order to satisfy the requirements of the Building Regulations.

## Volume 1 Chapter 8 Before The Work Is Finished Completion Certificates

Typically, the building owner will have received a completion certificate (from local authority building control) or a final certificate (from an approved inspector) before the building is occupied. These certificates are issued when the work is complete. In some circumstances a building may be occupied before the building owner has received the completion certificate or the final certificate. If this happens, the building owner will not be sure that the work meets all of the requirements of the Building Regulations and this may stop you from re-mortgaging your home or someone from buying your home.

## Other Legislation

The Regulatory Reform (Fire Safety) Order 2005 generally applies to most buildings other than houses or individual flats. This requirement comes from Regulation 38 of the Building Regulations. The Regulatory Reform (Fire Safety) Order creates the duty of the 'responsible person'. This person should take reasonable steps to reduce the risk from fire and make sure people can safely escape if there is a fire. The person carrying out the building work must provide fire safety information to the responsible person before the completion of the work. The responsible person should use this information when they carry out their fire risk assessment. Once a building is finished and occupied, other laws and regulations will apply. The Housing Act 2004 is relevant to residential properties. The Health and Safety at Work etc. Act 1974 covers buildings in which people are working. There are many other regulations which apply to buildings in use, some of which are listed in Appendix II. 

## Alterations

When buildings are extended or altered or their use is changed, Building Regulations are likely to apply again. This will be the case if the work is defined as building work or if the change of use comes under the scope of the Building Regulations. 

## Manual To The Building Regulations Volume 2: Further Guidance Chapter A Do The Building Regulations Apply? General Considerations

A1	
This second volume of the *Manual to the Building Regulations* looks in more detail at 
how the system works. It is intended to be used by people working professionally in the design and construction of buildings. 
A2	
Building control bodies can provide advice on when the Building Regulations apply.
A3	
Those carrying out building work (e.g. agents, designers, builders, installers and the 
building owner) are responsible for ensuring that the work complies with all applicable requirements of the Building Regulations.
A4	
If building work does not comply with the Building Regulations, the local authority may 
serve an enforcement notice on the building owner.
A5	
This manual can only provide a summary of the applicable legislation and, in addition, 
the legislation will be amended from time to time. You should always rely on the text 
of the legislation in preference to relying on the summary in this manual.

## Exempt Premises

A6	
The Building Regulations do not apply to some types of buildings or building work, 
and these are summarised in paragraphs A7 to A13 below. In the remainder of this chapter, where we refer to buildings, we are generally referring to buildings which are 
not exempt from the Building Regulations.

## Crown Buildings

A7	
The procedural aspects of the Building Regulations do not apply to Crown buildings, 
such as central government offices and courts of law. These have their own systems 

of control.

## Statutory Undertakers And Airport Operators

A8	
Statutory undertakers are bodies that have been given statutory powers in relation to functions that are of a public character. Generally, they are utilities, telecoms companies or companies such as Network Rail, but you should check. Gas and electricity suppliers are not regarded as statutory undertakers under Section 4 of the Building Act.
A9	
A building that belongs to a statutory undertaker, the Civil Aviation Authority or an airport operator is exempt from the Building Regulations if both of the following apply: a.	 The company uses the building for the purposes of its undertaking. 
b.	 Any building owned by a statutory undertaker is not used as either of the following:
i.	
a house or hotel
ii.	
an office or showroom, unless it is part of a railway station or airport.
A10	 The Metropolitan Police Authority is exempt from the procedural elements of the 
Building Regulations. Local authorities do not have powers of enforcement over the Metropolitan Police Authority. However, building work undertaken by the Metropolitan 
Police Authority is still subject to the same standards (referred to as 'substantive requirements' in the Building Act). 

## Exempt Buildings

A11	 Regulation 9 of the Building Regulations exempts some small buildings, extensions, 
and buildings used for specific purposes from the Building Regulations. Exempt 
buildings are defined in Schedule 2 to the Building Regulations and summarised in 
Table A1. The buildings must continue to meet the definitions in Schedule 2 after the works are complete.

## Table A1  Buildings Exempt From The Building Regulations

NOTE: If any water or electricity in an exempt greenhouse or building exempted under Class 6 or 7 
is supplied from or shared with a dwelling, the work must comply with the requirements of Schedule 1 for water supply and electricity. See Regulation 9 of the Building Regulations and Approved Documents G (G1 and G3) and P (P1). Certain works may be carried out under a competent person scheme, and these works will not require Building Regulations approval.

## Conservatories, Porches And Open-Sided Carports

A12	 The exemption in Class 7 (see paragraph A11) applies to conservatories, porches and 
open-sided carports only where the building control body is satisfied that all of the 
following conditions are met:
a.	 The work is an extension to an existing building. b.	 The extension is at ground level. c.	 The extension has a maximum floor area of 30m². d.	 Any glazing complies with requirements K4, K5.1, K5.2, K5.3 and K5.4 of Schedule 
1 to the Building Regulations.
e.	 Thermal separation is maintained between the building and the extension. 
f.	 The building's heating system does not extend into the extension. 
The requirements listed in a to d above come from Schedule 2 to the Building Regulations. The conditions set out in e and f come from the approved documents. Work to an existing conservatory or porch remains exempt to the same extent as building a new conservatory or porch, provided that the resulting conservatory or porch continues to meet the exemption criteria.

A13	 If the extension is not an exempt conservatory or porch (or other extension exempt 
under Class 7), then a building control process is required. 

## Building Work - General

A14	 Where a building is not exempt, the Building Regulations apply to the types of building 
work defined in Regulation 3 of the Building Regulations. This can include any of the following work: 
a.	 Erecting or extending a building (Regulation 3(1)(a)). b.	 Providing, extending or otherwise materially altering a controlled service or fitting 
(paragraphs A15 to A18) (Regulation 3(1)(b)).
c.	 Work required due to a material change of use (paragraph A20) (Regulation 3(1)(d)). d.	 Installing cavity wall insulation (Regulation 3(1)(e)). e.	 Underpinning a building (Regulation 3(1)(f)). f.	 Changes to a building's energy status (Regulation 22). g.	 Renovation or replacement of part of the thermal envelope (Regulation 23). h.	 Making certain changes to buildings over 1,000m² in area (Regulation 28). 

## Controlled Services And Fittings

A15	 Where a building is not exempt, the Building Regulations apply to providing or 
extending a controlled service or fitting.
A16	 A controlled service or fitting is a service or fitting to which the requirements of the 
following parts of Schedule 1 to the Building Regulations apply:
a.	 Part G Sanitation, hot water safety and water efficiency - this includes hot water 
systems, WCs and washing facilities.
b.	 Part H Drainage and waste disposal - this includes drainage systems and 

septic tanks.
c.	 Part J Combustion appliances and fuel storage systems - this includes boilers, 
fireplaces, flues, air supply to combustion appliances and fuel tanks. 
d.	 Part L Conservation of fuel and power - this includes heating and air conditioning 
systems, mechanical ventilation systems, external windows and doors and 

solar panels.
e.	 Part P Electrical safety - dwellings - this covers the fixed electrical system in 
dwellings or common parts of blocks of flats.
A17	 The relevant approved document (see Chapter 7) gives details of the requirements and 
performance standards of Parts G, H, J, L and P
.
A18	 Some requirements for controlled services or fittings only apply when dwellings are 
initially erected, and the fitting or service may not continue to be controlled after the dwelling has been completed. As long as any subsequent changes to the controlled service or fitting do not make it less compliant with Building Regulations than it was before the building work took place, the change does not have to comply with the Building Regulations.

## Material Alteration

A19	 The Building Regulations always apply to the material alteration of a building. An 
alteration is a material alteration under Regulation 3 if the proposals would at any stage 
make a building or a controlled service or fitting less satisfactory or no longer compliant in terms of structural safety, fire safety or disabled access. Building control bodies 
commonly ask for building control approval for structural works, such as chimney breast removal or structural alterations. 

## Material Change Of Use

A20	 The Building Regulations apply to building work when any of the following changes are 
proposed (this list is a summary of Regulation 5):
a.	 Changing a building's use to that of a dwelling. b.	 Creating a flat. c.	 Changing the use to become a hotel or boarding house. d.	 Changing the use to become a residential institution. e.	 Changing the use to become a public building. f.	 Changing the use so that the building would no longer be classed as exempt under 
Classes 1 to 6 of Schedule 2.
g.	 Changing the number of dwellings in a building that contains at least one dwelling.
h.	 Adding a room for residential purposes. i.	 Changing the number of rooms for residential purposes in a building with at least 
one such room.
j.	 Changing the use to that of a shop. k.	 Changing the building to become a relevant building as set out under Regulation 
7(4) when it was previously not a relevant building. 
In relation to change of use (k) above, Regulation 7 applies to buildings with a storey at least 18m above ground level and containing a dwelling or institution, and in some cases rooms for residential use. Under Regulation 6, where a material change of use is proposed, work must be carried out so that the building complies with the requirements indicated in Table A2. If only part of a building is affected by a material change of use, then under Regulation 6 
in most cases the Building Regulations apply only to the part that is subject to the change of use. However, the change of use may adversely affect other parts of a building, for example in relation to fire safety.

## Notes: 1.	B4(1) Applies To Buildings Over 15M High. It Applies To The Whole Building Even If The Change Of Use

only applies to a part.
2.	Where new residential accommodation is created. 3.	Applies to the whole building not just the parts converted to residential use. 4.	If the public building after the change contains a school. 5.	P1 applies in all cases if the electricity supply is shared with a dwelling. 6. Regulations 7(1) and 7(2) always apply to the above requirements.

## Volume 2 Repairs (Other Than Renovation Of Thermal Elements And Controlled Fittings)

A21	 The Building Regulations apply to repair or replacement work if the work is to renovate 
a thermal element (see paragraphs A22 and A23 below), replace a controlled fitting 
(see paragraphs A24 and A25), underpin a building or if the work is classed as building 
work under Regulation 3. Otherwise, unless at any stage the work makes:
a.	 any building that does not comply with Building Regulations less compliant or b.	 any building that does comply with Building Regulations non-compliant (as set out 
in Regulation 3(2)) 
then the Building Regulations do not apply to the repair or replacement work. 

## Renovation Of Thermal Elements And Controlled Fittings

A22	 Examples of thermal elements include roofs, external walls and ground floors. 
Examples of controlled fittings include windows and doors.
A23	 Major renovation and renovation of a thermal element are defined in Approved 
Document L1B, 5.6A and L2B, 3.1.
Under Regulation 23, if more than 50 per cent of a thermal element is renovated or replaced, the whole thermal element must comply with the current energy conservation requirements of requirement L1(a)(i) of Schedule 1 if technically and economically feasible. If a building undergoes major renovation, the same requirements from Schedule 1 apply. Renovation of a thermal element covers replacing a roofing membrane or adding a new layer (such as insulation). In case of repairs to thermal elements, such as a flat roof, which involve work to less than 50 per cent of the element's surface area, no thermal upgrade is required. 

A24	 If a controlled fitting, such as a window or door is replaced, and not just repaired, 
the replacement should comply with all relevant aspects of the current Building 
Regulations. For example, for an external door, relevant aspects of the Building 
Regulations include Part K (Protection from falling, collision and impact) and Part L 
(Conservation of fuel and power) and Regulation 7.
A25	 Guidance on complying with Regulation 23 is given in Approved Documents L1B and 
L2B. This includes consideration of listed buildings, buildings in conservation areas and 
scheduled ancient monuments. 

## Responsibility For Compliance

A26	 Ensuring that building work complies with all applicable requirements of the Building 
Regulations is the responsibility of those carrying out the work, for example, agents, 
designers, builders, installers and the building owner. Details of local authority enforcement powers are given in Chapter B. 

## Chapter B Should A Building Control Body Be Involved? Notification Of Work

B1	
When Building Regulations apply to the work you are proposing, then you either need to: a.	 involve a building control body (local authority building control or an approved 
inspector) or
b.	 use an installer registered under a competent person scheme to do the work.
You can use both a building control body and a competent person scheme on the same project. 

B2	
Except for the work described in paragraph B3, you must notify a building control body 
of all of the following:
a.	 Building work as defined under Regulation 3 of the Building Regulations. b.	 Any change in a building's energy status. c.	 Replacement or renovation of thermal elements. d.	 Material changes of use.
The building control body will then consider whether the work complies with the Building Regulations, although it remains the responsibility of those carrying out the building work to ensure that it does. 

B3	
Regulation 12(6)(a) states that a building control body does not need to be notified if 
one of the following conditions applies:
a.	 The work is listed in Schedule 4 to the Building Regulations. b.	 The work will be self-certified by a registered competent person. c.	 The work will be certified by a registered third party.
B4	
The person carrying out the building work can choose which type of building control 
body to notify. This same building control body will then inspect the work. The two types of building control body are:
a.	 local authority building control b.	 approved inspectors. 
B5	
Some work does not have to be checked by a building control body but must 
still comply with the Building Regulations. An example is installing loft insulation 
unconnected to a material change of use or other building work. In all cases, seek advice from a building control body to see if Building Regulations apply.
B6	
If building work does not comply with the Building Regulations, the local authority 
building control body can take enforcement action.

## Enforcement Action

B7	
The Building Regulations can be contravened by not following the correct procedures 
or not meeting the required technical performance requirements. 
B8	
Local authorities may take enforcement action if notifiable building work (as set out in 
paragraph B2 above) is carried out without having previously notified the local authority by submitting a Building Regulations application or an initial notice.
B9	
Local authorities may also take enforcement action if building work does not comply 
with Building Regulations. 
B10	 Under Section 95 of the Building Act, local authorities have the right of entry into 
buildings in relation to enforcing the Building Act.
B11	 Under Sections 35, 35A and 36 of the Building Act the local authority has the power to 
take enforcement action. Local authorities can take action against the building owner and those carrying out the works and this can include requiring that the works are pulled down or removed. 
B12	 If the building owner or those carrying out the works contravene the Building 
Regulations, the local authority may prosecute them in the magistrates' court, where an unlimited fine may be imposed (Sections 35 and 35A of the Building Act).

## Regularisation Certificates

B13	 Where unauthorised building work has been carried out on or after 11 November 
1985, it may be possible to obtain a regularisation certificate from the local authority. If issued, the regularisation certificate shows that the works complied with the Building 
Regulations that were in place when the unauthorised work was carried out. 
B14	 Regulation 18 lists the information to include in an application for a regularisation certificate.
This includes both of the following: 

a.	 A description, preferably including drawings, of the unauthorised work. b.	 Plans showing any additional work needed to ensure compliance with the Building 
Regulations which were in force when the work was originally carried out.
B15	 The local authority may require the building owner to take reasonable steps so that it 
can decide what work, if any, is needed to comply with the Building Regulations. Such 
steps may include laying open work or carrying out tests. 
B16	 When the local authority has sufficient information, it will tell the building owner what 
work, if any, is needed to comply with the Building Regulations. 
B17	 If the specified work has been completed to its satisfaction, the local authority can 
issue a regularisation certificate to the building owner. However, the local authority has no obligation to issue a regularisation certificate. 

## Chapter C Competent Person Schemes And Third-Party Testing Competent Person Schemes

C1	
For some types of building work, such as replacing certain windows or reroofing, people working under a relevant approved competent person scheme can self-certify 
that their work complies with the Building Regulations.
C2	
Competent person schemes are set up under Regulation 20 and listed in Schedule 3 
to the Building Regulations. An up-to-date list of current schemes is also given at:
https://www.gov.uk/guidance/competent-person-scheme-current-schemes-and-howschemes-are-authorised#current-schemes 

C3	
If building work is carried out under a competent person scheme, there is no need to 
submit a building notice or an initial notice or to deposit full plans for that work.
C4	
The competent person will notify the local authority of the work and issue a completion 
certificate, either directly or through the scheme operator. The certificate must be given to both the building occupier and the local authority within 30 working days of completion of the work.
C5	
If you don't receive a certificate within 30 days of completion, contact the competent 
person scheme operator that your installer is registered with and they may be able to 
help you resolve the matter.
C6	
Even if work is carried out under a competent person scheme, if the work contravenes 
the Building Regulations, local authority building control still have enforcement powers.

## Third-Party Testing For Airtightness

C7	
Third-party certification schemes are available for testing airtightness, enabling approved airtightness testers to certify that the work meets the required performance standard. These are established under Regulation 43 of the Building Regulations. An 
up-to-date list of testing organisations can be found at:
https://www.gov.uk/guidance/competent-person-scheme-current-schemes-and-howschemes-are-authorised#types-of-building-work

## Volume 2 Third-Party Testing Of Domestic Electrical Work

C8	
Under a third-party certification scheme for electrical installations in dwellings, a person who is registered with the scheme can inspect and test the domestic electrical work of others and certify that it complies with the Building Regulations. This is expanded upon 
in more detail in Approved Document P
. 
C9	
Third-party certification schemes for electrical installations in dwellings are listed in Schedule 3A to the Building Regulations. An up-to-date list is also given at: 
https://www.gov.uk/guidance/third-party-certification-schemes-for-domesticelectrical-work

C10	 If electrical work is approved under a third-party certification scheme, there is no need 
to submit a building notice or an initial notice or to deposit full plans for that work.
C11	 The operator of the third-party certification scheme will notify the local authority of work 
that complies with the Building Regulations. 

## Chapter D Local Authority Building Control

D1	
Local authorities provide a building control service for all categories of work and all types of building. Local authorities may also be responsible for other statutory requirements, including town planning, listed building consent and licensing, that may 
affect the design of the building. 
D2	
If you are planning to carry out building work that needs to be checked by a building 
control body you can choose either of the following routes:
a.	 depositing full plans (described in Regulation 14) or b.	 submitting a building notice, which contains less information than full plans (see 
Regulation 13).
D3	
To start work without either depositing full plans or submitting a building notice is 
likely to contravene Regulation 12, unless the exceptional circumstances set out in 
Regulation 12(8) are applicable. If Regulation 12 is contravened, the local authority can 
prosecute. In either of the cases detailed above, the applicant may be required to pay a penalty.
D4	
It is necessary to deposit full plans instead of a building notice if any of the following 
work is proposed:
a.	 Building work in relation to a building to which the Regulatory Reform (Fire Safety) 
Order 2005 applies or will apply after building work is complete. Examples of such buildings include hotels, boarding houses, offices, shops and factories.
b.	 Building work that includes erecting a building that fronts a private street.
c.	 Building work that involves building over or otherwise interfering with an existing 
shared drain, sewer or disposal main shown on a map of sewers. 

## Deposit Of Plans

D5	
When full plans are deposited, the applicant must pay the plan charge to the 

local authority.
D6	
The local authority must pass or reject the full plans within five weeks, or within two months if the applicant has agreed to an extension of time in writing (see Section 16 of the Building Act). 
D7	
The local authority may reject the plans for either of the following reasons: a.	 The plans show that work will contravene the Building Regulations. b.	 The plans are defective (for example incomplete) - they fail to show that work will 
comply with the Building Regulations.
The local authority must give the reason in the notice of rejection.

## Building In Accordance With Deposited Plans

D8	
Building work does not need to conform exactly to the plans but must comply with the requirements of the Building Regulations. 
D9	
If building work deviates from what the deposited and passed (or not rejected) plans 
show, the local authority may require this work to be taken down or altered. It is therefore advisable to consult the local authority before deviating from approved plans. 

## Building Notices

D10	 A building notice may be used where the Regulatory Reform (Fire Safety) Order 2005 
does not apply. Where the building work is simple and drawings are not required, this 
may be appropriate. 
D11	 The building notice enables work to be started without having to provide the local 
authority with plans. The local authority must be informed before the work is started. 
D12	 When a building notice is deposited, the building notice fee must be paid to the local 
authority. The building notice fee is similar to the combined plan and inspection fees of the full plans option. 
D13	 The building notice will typically be submitted on a form produced by the local authority 
and should include the information specified in Regulation 13. In the case of a new 
building or extension, the information should include a site plan.
D14	 Once the building notice has been deposited, the local authority may ask in writing for 
further information. 
NOTE: Once the building notice has been submitted, building work may start on the third day after the local authority has been informed. If building work has not started within three years of a building notice being deposited, under Regulation 13(5) the building notice is no longer valid. 

D15	 The local authority is not required to pass or reject a building notice. If you use a 
building notice instead of the full plans route, then both of the following apply:
a.	 You will not have the protection of having full plans passed by the local authority. If 
the local authority has passed your plans, then you know that they are happy for you to build from them. 
b.	 You cannot ask the Secretary of State for a determination if the person carrying out 
the building work disagrees with the requirements of the local authority. 
D16	 If building work contravenes the Building Regulations, the local authority can require 
the work to be altered or removed.

## Consulting The Fire Authority

D17	 Details of the consultation procedures that should be followed at the design and 
construction stages of a building project are given in the Joint Regulators Group's forthcoming Technical Guide: Building Regulations and Fire Safety Procedural 

Guidance (2020). 

## Consulting The Sewerage Undertaker

D18	 When full plans have been deposited with the local authority and the work affects a 
drain, sewer or disposal main (as described in paragraph D4(c)), under Regulation 15 the 
local authority must consult the sewerage undertaker. The local authority must consider the views of the sewerage undertaker before passing the plans or issuing a completion 
certificate. The local authority must be satisfied that work will not be detrimental to either the building in question or the continued maintenance of any drain, sewer or disposal main.

## Conditional Passing Of Plans

D19	 A local authority may pass plans subject to either or both of the following conditions, 
under Section 16(2) of the Building Act: a.	 The local authority may pass the plans subject to required additions or amendments 
being made. 
b.	 The local authority may request further plans to be submitted.
NOTE: The local authority is not obliged to use these procedures. The written agreement of the applicant is required.

## Starting Work

D20	 When a building notice has been served, building work may begin at any time provided 
the local authority is given two clear working days' notice of the intention to start work, as required by Regulation 16(1). 
D21	 When full plans have been deposited and the notice described above has been given, 
work may begin. 

## Giving Notices At Relevant Stages

D22	 You are required under the Building Regulations to give the local authority notice 
of when the work has reached relevant stages. The local authority will set out the notification procedure. The work should be programmed to allow the local authority time to inspect at the required stages.
D23	 If the local authority is not informed of a relevant stage of work for inspection it may, by 
giving notice in writing, require the work to be opened up for inspection so that it can be ascertained whether or not the work complies with the Building Regulations.

## Contravention Of The Requirements

D24	 During the building work, or within a year of its completion, if the local authority 
considers that the work contravenes any requirement of the Building Regulations, it 
may serve a notice under Section 36 of the Building Act requiring the work to be taken down or altered within 28 days. 
D25	 Where the person who carried out the work disagrees with the local authority, they may 
notify the local authority that they want to obtain an independent expert report under 
Section 37 of the Building Act. In this case, the deadline for the work to be taken down is extended to 70 days.

D26	 Where the local authority has considered an expert report, it may withdraw the Section 
36 notice.
If the local authority does not withdraw the notice, the person who carried out the work may appeal to the magistrates' court under Section 40 of the Building Act. 

## Completion Certificates

D27	 Once the work has finished, and if they are satisfied that the work complies with 
the relevant provisions of the Building Regulations, the local authority must issue a 
completion certificate. 
D28	 The relevant provisions of the Building Regulations are Regulations 25A, 26, 29, 36, 38 
and Schedule 1. The first four of these regulations deal with environmental performance and Regulation 38 concerns fire safety information. 
D29	 The local authority is authorised to accept testing carried out in accordance with 
Regulations 41 to 44 as demonstrating that the requirements in the Building 
Regulations have been satisfied. 

## Duration Of Approval

D30	 If building work does not commence within three years of the date when the local 
authority passed the plans, the local authority may serve a notice under Section 32 of the Building Act to rescind the approval. It is important to note that this is different to 
the requirements for starting work under planning legislation. 

## Determinations And Appeals

D31	 The local authority has the power (under Regulation 11 of the Building Regulations) to 
relax requirements of the Building Regulations other than those relating to:
a.	 Regulation 23(1)(a)
b.	 Regulation 25A c.	 Regulation 25B d.	 Regulation 26 and e.	 paragraph R1 of Schedule 1 to the Building Regulations.
Those responsible for the building work may submit a formal application to the local authority for relaxation of the Building Regulations. 

D32	 If, after a request, the local authority refuses to ignore or relax the requirements, the 
person carrying out the building work can appeal to the Secretary of State.
Details of appeals can be found at: www.gov.uk/guidance/building-regulations-appeals--6

D33	 If the local authority and the person carrying out the building work disagree about 
whether work shown on full plans complies with the Building Regulations, a determination can be requested from the Secretary of State before work starts. There is no statutory timetable for this process.
Details of determinations can be found at: www.gov.uk/guidance/building-regulations-determinations

## Chapter E Approved Inspectors

E1	
This chapter refers to the Building (Approved Inspectors etc.) Regulations 2010, subsequently referred to as the Approved Inspectors Regulations.
E2	
Approved inspectors are companies or individuals, licensed through CICAIR Ltd under the Building Act to provide a building control service for all categories of work and for 
any building type. With the exception of minor works, approved inspectors must be 
financially and professionally independent of the work they inspect. Minor works are defined in Regulation 9(5) of the Approved Inspectors Regulations.
E3	
Approved inspectors are independently monitored and regulated by CICAIR Ltd to carry out building control work in England (and Wales). CICAIR Ltd is a wholly owned subsidiary of the Construction Industry Council (CIC) and the approval process it operates provides a route to registration as an approved inspector. For more 
information, visit the CICAIR website:
https://www.cicair.org.uk/

E4	
Approved inspectors are required to have insurance from a government approved scheme.
E5	
The person carrying out the building work enters into a formal contract with the approved inspector and may negotiate the fees involved. 

## The Initial Notice

E6	
When the person carrying out the building work engages an approved inspector, that 
person and the approved inspector must together give the local authority an initial notice.
E7	
The contents of an initial notice are outlined in Form 1 in Schedule 1 to the Approved 
Inspectors Regulations. The initial notice must contain all of the following:
a.	 A description of the work. b.	 In the case of a new building or extension, both of the following: 
i.	
A site plan to a scale of not less than 1:1250 showing the boundaries and location of the site.
ii.	
A statement that if work involves building over or near any drain, sewer or disposal main shown on any map of sewers kept by the sewerage undertaker, the approved inspector will consult the sewerage undertaker.
E8	
The initial notice must show how any new drainage will be connected. a.	 If drainage will be connected to an existing sewer, it is often sufficient to indicate on 
the site plan the points at which the drainage will be connected. 
b.	 If drainage will not be connected to an existing sewer, the initial notice must 
describe how drainage discharges will be dealt with. For example, this could include details of the location of any septic tank and associated secondary treatment system, or any wastewater treatment system or cesspool.

## Acceptance Or Rejection Of Initial Notice

E9	
After receiving an initial notice, the local authority has five working days in which to consider its validity. 
E10	 If the local authority considers that the initial notice contains insufficient information, 
it may reject it. The local authority may only reject an initial notice on the grounds prescribed in Schedule 2 to the Approved Inspectors Regulations. 
E11	 If the local authority does not reject the initial notice within five working days of receipt, 
it is presumed to have accepted the initial notice unconditionally.
E12	 Once the initial notice has been accepted or is deemed to have been accepted (five 
days after receipt), the approved inspector will certify that they are satisfied that the 
works have been completed. 
NOTE:  Those responsible for carrying out the building work (which includes clients, designers, builders and installers) must ensure that the work complies with the Building Regulations.

## Independence Of Approved Inspectors

E13	 Approved inspectors must have no professional or financial interest in the work that 
they supervise, and should be independent of the designer, builder or building owner, unless the work comprises any of the following: 
a.	 The material alteration or extension of a one or two storey house, provided that 
the house has no more than three storeys when work is complete (ignoring any basement storeys).
b.	 The provision, extension or material alteration of a controlled service or fitting in 

any building.
c.	 The underpinning of any building. 

## Consulting The Fire Authority

E14	 If work is proposed to a building to which the Regulatory Reform (Fire Safety) Order 
2005 applies or will apply once building work is complete, the approved inspector must 
consult the fire authority at each of the following stages:
a.	 Before or as soon as practicable after giving an initial notice (or amendment notice 
where there is a need to subsequently change the initial notice), the approved inspector must supply the fire authority with sufficient information to show that the 
work described in the initial notice will comply with Part B (Fire safety) of Schedule 1 
to the Building Regulations.
b.	 Before giving a plans certificate (whether combined with an initial notice or not), the 
approved inspector must give the fire authority a copy of the relevant plans.
c.	 Before giving a final certificate.
E15	 Before giving a plans certificate or final certificate to the local authority, the approved 
inspector must allow the fire authority up to 15 working days to comment. The 
approved inspector must consider the views of the fire authority.

## Consulting The Sewerage Undertaker

E16	 If an initial notice or amendment notice involves proposals to erect or extend or carry 
out underpinning works to a building within 3 metres of the centreline of a drain, sewer or disposal main to which paragraph H4 of Schedule 1 to the Building Regulations 
applies, the approved inspector must consult the sewerage undertaker.
E17	 Before giving a plans certificate or final certificate to the local authority, the approved 
inspector must allow the sewerage authority up to 15 working days to comment. The approved inspector must consider the views of the sewerage authority.

## Plans Certificate

E18	 A plans certificate can be used to demonstrate that detailed plans of the work or a 

part of it comply with the Building Regulations. A plans certificate can provide 
protection if the initial notice is cancelled or ceases to be valid and no new initial notice is given or accepted. 
E19	 Plans certificates are described in Regulations 14 and 15 of the Approved Inspectors 
Regulations and Section 50 of the Building Act. The person proposing the building 
work can ask the approved inspector to supply a plans certificate. If the approved inspector is satisfied with the plans, they must give a plans certificate to both of the following parties:
a.	 the person proposing the building work and 
b.	 the local authority. 
The approved inspector can give the plans certificate with the initial notice or later. 

## Final Certificate

E20	 When the building work is complete and the approved inspector is satisfied that the 
work meets all the relevant requirements of the Building Regulations, the approved inspector must give the local authority a final certificate as described in Section 51 of the Building Act and Form 5 of Schedule 1 to the Approved Inspectors Regulations. A 
final certificate provides evidence, but not conclusive evidence, of compliance with the 
Building Regulations. 
E21	 A final certificate need not relate to all the work specified in an initial notice. For 
example, for a single initial notice that covers a new housing estate, separate final or plans certificates might be given for individual houses or groups of houses.
E22	 The local authority may reject the final certificate only on the grounds given in Schedule 
4 to the Approved Inspectors Regulations. The local authority has 10 working days within which to reject the final certificate, otherwise it is deemed to have been accepted. If a final certificate is rejected, the initial notice ceases to be valid four weeks later.

## Events Causing The Initial Notice To Become Invalid

E23	 There are limitations on the validity of the initial notice, where the initial notice has been 
given to erect, extend or materially alter a building. This applies when any part of the building or extension is subsequently occupied and no final certificate has been given. In such situations the initial notice is no longer valid after a 'relevant change of use', as described in Regulation 12(6) of the Approved Inspectors Regulations.
E24	 For most buildings, the initial notice will lapse eight weeks from the date when the 
building is occupied. 
For buildings comprising only flats and common parts, the initial notice will lapse four weeks after the building is occupied.

NOTE: A local authority can, however, extend the period of the initial notice. The local authority may wish to extend the period if it is reasonably confident that a final certificate will be given soon. 

E25	 In case of a material change of use covered by an initial notice (paragraph E23), if the 
change of use takes place and no final certificate is given, the initial notice for the work will no longer have effect eight weeks after the change of use.
E26	 Once the initial notice no longer has effect, both of the following situations apply:
a.	 The approved inspector will be unable to give a final certificate. b.	 The local authority has the power, under Section 36 of the Building Act, to take 
enforcement action against non-compliant work. 
This has the same consequences as an approved inspector withdrawing 

(as described below). 

## Withdrawal Of Approved Inspector

E27	 An approved inspector who cannot continue to supervise work for which they have given 
an initial notice must cancel the initial notice and inform both of the following parties: 
a.	 The person doing the building work. b.	 The local authority. 
E28	 If the person responsible for the work (building owner or client) becomes aware that 
the approved inspector is unable to continue supervising the work, the owner or client 
must cancel the initial notice (see Section 52 of the Building Act and Regulation 18 of 
the Approved Inspectors Regulations).
E29	 The person responsible for the work (building owner or client) may give a new initial 
notice jointly with a new approved inspector provided the original approved inspector agrees to cancel the earlier notice as soon as the new notice is accepted (see Schedule 2 to the Approved Inspectors Regulations, paragraph 12). 

## Change Of Person Intending To Carry Out Work

E30	 If a different person from that named in the original initial notice intends to carry out 
the work, the procedure is as follows. The approved inspector and the person who 
originally intended to carry out the work may jointly give written notice to the local authority to state that a new person or organisation intends to carry out the work (Section 51C of the Building Act). The initial notice is then treated as having been given 
by the new person intending to carry out the work and the approved inspector. 
E31	 In a situation where the approved inspector considers that the building work does not 
comply with the Building Regulations and there is a refusal to bring it into compliance, 
the approved inspector will cancel the initial notice. If no other approved inspector takes on the work, the building control function will automatically be taken on by the 
local authority. From this point, the local authority will have enforcement powers. 

## Local Authority'S Powers In Relation To Partially Completed Work

E32	 If an initial notice is no longer valid, the local authority becomes responsible for 
enforcing the Building Regulations in relation to any completed work for which a final 
certificate has not been given (Regulation 19 of the Approved Inspectors Regulations). 
The local authority must be provided with both of the following:

a.	 Plans of the building work carried out, if requested by the local authority. b.	 Plans referred to in a plans certificate where granted by the approved inspector. 
E33	 For any partially completed work, the local authority may require the person carrying 
out building work to cut into, lay open or pull down work so that the local authority may determine whether any work (not covered by a final certificate) contravenes the 
Building Regulations. However, the local authority cannot take action against that person in relation to any work carried out as described in a plans certificate.
E34	 If it is intended to continue with partially completed work, the local authority must be 
given sufficient plans to show that the work can be completed without contravening 
the Building Regulations. 
NOTE: Where an approved inspector is used, the local authority cannot give a notice under Section 36 of the Building Act to remove or alter any offending work so long as the initial notice remains valid. Work covered by an approved inspector's final certificate that the local authority has accepted cannot be subject to local authority action under Section 36 of the Building Act.

## Contravention Of Building Regulations

E35	 An approved inspector cannot enforce the Building Regulations. If work appears not to 
comply with the Building Regulations, an approved inspector may, however, give the person carrying out the building work a written notice. 
E36	 If the work that appears not to comply with the Building Regulations is not remedied 
within three months, the approved inspector must cancel the initial notice. The approved inspector must give the person carrying out the building work and the local 
authority a cancellation notice in the set form. This notice must describe how the work appears not to comply with the Building Regulations (see Section 52 of the Building 
Act and Regulation 18 of the Approved Inspectors Regulations).

## Volume 2 Limitations On The Enforcement Powers Of Local Authorities

E37	 If the initial notice ceases to be in force (as described in Section 47(1) of the Building 
Act) and the conditions in Section 53(2) of the Building Act are satisfied, the local 
authority may not:
a.	 give a notice under Section 36(1) of the Building Act (removal or alteration of work 
which contravenes Building Regulations) or
b.	 institute proceedings under Section 35 of the Building Act for a contravention of 
Building Regulations.
For details of this situation, refer to Regulation 15 of the Approved Inspectors Regulations.

## Dealing With Variations To The Work

E38	 To vary the work detailed in an initial notice (e.g. to build six units instead of five on a 
site), the person carrying out the building work and the approved inspector should give the local authority an amendment notice. (See Sections 51A and 51B of the Building 
Act and Form 2 of Schedule 1 to the Approved Inspectors Regulations). 

## Contents Of An Amendment Notice

E39	 The amendment notice must be as described in Form 2 in Schedule 1 to the Approved 
Inspectors Regulations. The amendment notice must contain the information required for an initial notice (set out above in paragraph E7) plus either of the following: 
a.	 A statement that all plans submitted with the original notice remain unchanged. b.	 Copies of all the amended plans with a statement that any plans not included 
remain unchanged. 

## Acceptance And Rejection Of Amendment Notice

E40	 The local authority has five working days in which to consider the amendment notice. 
The local authority may only reject the amendment notice on grounds set out in 
Schedule 2 to the Approved Inspectors Regulations. The procedure is identical to that for accepting or rejecting an initial notice. 

## Duration Of Validity Of Initial Notices And Plans Certificates

E41	 If work has not started within three years of the date on which an initial notice was 
accepted or deemed to have been accepted, a local authority may cancel an initial notice under Section 52(5) of the Building Act. 
If work has not started within three years of accepting a plans certificate, the local authority may rescind its acceptance, under Section 50(8) of the Building Act.

## Determinations And Appeals

E42	 An approved inspector cannot relax Building Regulations. However, the building owner 
or client can apply to the local authority to relax Building Regulations, even when an 
approved inspector is used.
E43	 Before work begins, if the approved inspector and the person carrying out the 
building work disagree about whether the work shown on the plans complies with the Building Regulations, the building owner or client can request a determination from the Secretary of State.
E44	 Once work has started, the only recourse against the decision of the building control 
body is an appeal to the Secretary of State.
E45	 Details of appeals and determinations can be found at: 
Appeals: www.gov.uk/guidance/building-regulations-appeals--6 
Determinations: www.gov.uk/guidance/building-regulations-determinations 

## Local Authorities Acting As Approved Inspectors

E46	 Local authorities can operate as approved inspectors beyond the boundaries of their 
local authority area. 

## Chapter F Meeting The Technical Requirements The Approved Documents

F1	
The approved documents set out what, in ordinary circumstances, may be accepted as one way to comply with the Building Regulations. However, Section 7 of the Building 
Act indicates that following the guidance in approved documents may be relied upon 
as tending to negative liability, while failing to follow the guidance may be relied upon as tending to establish liability. Therefore, following the approved documents alone does 
not guarantee compliance. 
F2	
It remains the responsibility of those designing or undertaking building work to 
assess, on a case-by-case basis, whether specific circumstances require additional or alternative measures to achieve compliance with the regulatory requirements. 
F3	
Following industry guidance referenced in the approved documents may, depending on 
the circumstances, have the same legal effect as following the approved document itself. 
Using other guidance, including a different version of a referenced guidance document, would not give the same legal presumption. Figure F1 shows how the approved documents and other sources of guidance fit into the overall regulatory system.
F4	
Approved documents vary in length and complexity and in how the guidance applies to different types of buildings. 
Table 1.1 in Chapter 1 of this manual lists the approved documents for different types of new or existing dwellings and other buildings.

F5	
In some mixed-use developments, parts of a building are used as dwellings while other 
parts have non-domestic uses. If the requirements of the approved documents for 
dwellings and other buildings differ, the more onerous requirements apply in any shared 
parts of the building. This is discussed in detail with regard to fire safety in Approved 
Document B and ventilation in Approved Document F. 
F6	
When an approved document refers to a named standard, the relevant version of the 
standard is listed at the end of the approved document. Until the approved document 
is amended, these references are part of the guidance approved under Section 6 of the Building Act. 
If work complies with the guidance referred to in the approved document, that makes it likely that the work conforms with the relevant requirements of the Building Regulations. Following other guidance would not provide that legal protection.

F7	
If an approved document refers to an older version of a standard that the issuing standards body has now revised or updated, the new version may be used as a source of guidance, provided it continues to address the relevant requirements of the Building Regulations.

## Designing And Constructing Buildings

F8	
Any building work that is subject to the requirements imposed by Schedule 1 to the 
Building Regulations must be carried out in accordance with Regulation 7. Building 
work is defined in Regulation 3.
F9	
Building work under Regulation 7 shall be carried out: a.	 with adequate and proper materials which
i.	
are appropriate for the circumstances in which they are used
ii.	
are adequately mixed or prepared and
iii.	 are applied, used or fixed so as adequately to perform the functions for which 
they are designed, and
b.	 in a workmanlike manner.
F10	 Regulation 7 places requirements on materials and workmanship to deliver the 
performance required under the Building Regulations. Those responsible for building work must be able to demonstrate that both materials and workmanship comply with 
the Building Regulations, as part of the overall scheme. 
F11	 Regulation 7 applies to all building work to which the Building Regulations apply. 
However, in accordance with Regulation 8, the standards of materials and 
workmanship need be no higher than are necessary to satisfy the following conditions: 
a.	 For Parts A–D, F–K and P (except for paragraphs G2, H2 and J7) of Schedule 1: to 
secure reasonable standards of health or safety for people in or about the building. 
b.	 For Part E of Schedule 1: to secure reasonable resistance to the passage of sound 
for the welfare and convenience of people in or about the building.
c.	 For Part L of Schedule 1: to conserve fuel and power. d.	 For Part M of Schedule 1: to provide access to buildings and their facilities for people.

## Demonstrating Compliance

F12	 Whether materials and associated workmanship meet the requirements of the Building 
Regulations could be established in a number of different ways. It may be necessary to 
use more than one of these methods to provide appropriate evidence of compliance. The properties of the materials and workmanship being demonstrated as fit could be 
established by the methods listed below. a.	 A CE marking, provided it is relevant and the product is used appropriately. 
Accompanying performance information may not cover all of the required properties of the product.
b.	 Following relevant guidance of the approved documents or standards referenced by 
the approved documents.
c.	 Compliance with a relevant British or European standard or standards. d.	 Compliance with a relevant ISO or other national technical standards. e.	 Use of a competent person scheme to carry out work or to certify materials and 
workmanship within the scope of the scheme.
f.	 Use of an independent certification scheme accredited by a certification body 
belonging to the European co-operation for Accreditation (EA). In the UK, the United Kingdom Accreditation Service (UKAS) is the national accreditation body.
g.	 Past experience from safe and successful longstanding relevant practice in the 
existing building stock. Existing practice should be reviewed to ensure that it is safe, appropriate and relevant to the proposed conditions.
h.	 Tests are often used to show that materials and workmanship are appropriate. In 
many circumstances, testing is one way of showing compliance, but in the following three instances the Building Regulations require those undertaking building work to 
have tests carried out to demonstrate compliance.
i.	
Sound insulation as described in Regulation 41.
ii.	
Air flow rate of mechanical ventilation as described in Regulation 42. 
iii.	 Pressure testing as described in Regulation 43.
i.	 Where there is no relevant harmonised European standard, calculations 

against appropriate standards could demonstrate the compliance of materials and workmanship.

## Other Design Standards

F13	 Where design standards other than those referred to in the approved documents are 
used, it is important that the acceptability of these standards is discussed with the building control body in advance. It should be noted that building control bodies may 
not be familiar with all standards, and mixing standards produced by different bodies may be unacceptable. 

## Ce Markings Under The Construction Products Regulations

F14	 The future status of CE markings may be reviewed as part of the UK exiting the 
European Union. 
F15	 At present, CE markings are used to demonstrate that either:
a.	 a product complies with a harmonised European standard or standards (British 
versions of standards are numbered starting BS EN and contain an Annex ZA) or
b.	 a product has undergone a European Technical Assessment.
F16	 CE marking includes the reference of the product standard and the levels or classes 
of performance being declared against some or all of the characteristics covered by the standard. The CE marking should be on the product, its label, the packaging or 
accompanying documents. The CE symbol by itself does not necessarily indicate that the material is suitable for the building work.
F17	 In addition to CE marking, the product will have a declaration of performance 
containing more detailed information on the product. This may be a paper or electronic document, or it may be on a website. It is essential to check that the declared performance is suitable for the building work.
F18	 In the absence of indications to the contrary, the building control body may assume 
that the information given in the CE marking and declaration of performance is accurate and reliable, and that the product meets the declared performance.
F19	 If the declared performance of a product is suitable for its intended use and the 
product is installed correctly, the building control body should not unreasonably prohibit 
or impede the use of the product.

## Optional Requirements

F20	 Local planning authorities may impose planning requirements that may exceed the 
minimum standards required by the Building Regulations. These may include the following cases: a.	 accessible housing (Requirements M4(2) and M4(3) of Schedule 1 to the 

Building Regulations) 
b.	 water efficiency (Regulation 36).
F21	 Such planning requirements will appear as conditions in the relevant planning consent. 
Enforcement of such options is part of the planning process. However, it is important that the building control body is made aware of such planning conditions.

## Historic Buildings

F22	 The Building Regulations should be complied with in a manner that respects historic 
buildings and environments. Local authority building control officers and conservation 
officers may be able to advise on how to comply appropriately with Building Regulations. 
F23	 Approved Documents B, C, E, F, G, H, J, L and M provide detailed guidance on 
meeting the Building Regulations in historic buildings.
F24	 Additional guidance is available in Historic England's Energy Efficiency and Historic 
Buildings: Application of Part L of the Building Regulations to historic and traditionally 
constructed buildings. This can be downloaded from the following website: 
https://historicengland.org.uk/images-books/publications/energy-efficiency-historicbuildings-ptl/

## Design And Construction Tolerances

F25	 Dimensions given in the approved documents make no mention of any allowance 
for construction tolerances. To ensure that design standards are met, appropriate allowance for tolerance should be considered in the design process. A critical dimension may depend on multiple construction tolerances. Industry standards may provide guidance on achievable tolerances. 

## Ban On Combustible Materials

F26	 The use of combustible materials in the external walls and specified attachments of 
certain buildings with a storey at 18m or more above ground level is prohibited by the Building Regulations. See Regulation 7(2) of the Building Regulations and Approved 
Document B: Volume 2, part B4 for details.
NOTE: The requirement B4(1) applies to buildings of any height. The external walls of the building shall adequately resist the spread of fire over the walls and from one building to another, having regard to the height, use and position of the building.

## Volume 2 Volume 2 Properties Of Certain Materials

F27	 Some materials, in the absence of special care, may be considered unsuitable because 
of their rapid deterioration in relation to the expected life of the building.
F28	 A short-lived material which is readily accessible for inspection, maintenance 
and replacement may meet the requirements of the Building Regulations if the 
consequences of failure are not likely to be serious to the health or safety of people in and around the building.
F29	 If a short-lived material is not readily accessible for inspection, maintenance and 
replacement, and the consequences of failure are likely to be serious for health or safety, it is unlikely that the material will meet the requirements of the 

Building Regulations.
F30	 A local authority may impose conditions on the proposed use of short-lived or 
otherwise unsuitable materials under Section 20 of the Building Act. 
F31	 If a material is at risk of spontaneous failure, such as toughened glass, and the 
consequences of failure are likely to present a safety risk, it is unlikely that the material 
will meet the requirements of the Building Regulations.

## Sampling By Building Control Bodies

F32	 A local authority may take samples to establish whether materials that are used in 
building work comply with the Building Regulations under Regulation 46.
F33	 An approved inspector may sample materials under Regulation 8 of the Approved 
Inspectors Regulations.

## Record Keeping

F34	 Those carrying out building work will want to keep accurate records on the source 
of materials to help demonstrate that materials comply with Regulation 7 or other 
requirements in the Building Regulations.

## Enduring Powers Under The Building Act

F35	 Once building work is complete the Building Regulations no longer control the materials 
or workmanship used. Outside the building control process, the Building Act gives local authorities powers in relation to unsafe buildings and structures. Any changes to a building may trigger a new building control process, as detailed earlier in this manual. 

## Appendix I Key Terms
