Register your business as a building control approver
Source: gov.uk (2025-03-26)

All private sector businesses that want to do building control work in England and Wales under the Building Act 1984 (as amended) must apply to register with the Building Safety Regulator (BSR).

To apply, call us on xx-xxxx-xxxx. Your standard call rates (https://www.gov.uk/call-charges) will apply.

We’ll ask for your email address and send you an application form, spreadsheet and ShareFile link with instructions on how to complete and upload your application.

Who should register

An RBCA can be a standalone business, part of a wider corporate group, a sole trader or partnership.

A senior employee who can represent the business should submit the application. For example, an owner, director, partner or senior manager. This person will be the main contact for BSR.

What we will ask you for

During your application we’ll ask you to provide:
- information about your business, such as name, address, email and phone
- the building control functions your business will do, and whether it offers additional services other than building control
- information about the person who we should contact to discuss your application, such as name, email and phone, and their role in the business
- the number of registered building inspectors and building inspectors waiting to be registered which your business employs or contracts with
We’ll ask if your business is, or was, an approved inspector registered with CICAIR, whether it is subject to any ongoing action, such as sanctions, and whether you have any current higher-risk building projects in progress.

We’ll ask you to upload a diagram of the organisational structure of your business, including where it is part of a wider group structure.

We’ll ask you for the names of current owners and directors, and:
- any other companies they are directors of or hold an interest in that may cause a conflict of interest
- whether they have any relevant unspent criminal convictions
We’ll ask if the business or any of its managers or building inspectors have been subject to HSE enforcement action in the last 5 years.

We’ll ask you to confirm that your business has written operating procedures covering your planned building control work.

We’ll ask you to confirm that your business has policies for:
- recruitment and development
- whistleblowing
- conflicts of interest
- money laundering
- health, safety and wellbeing
- data protection
- staff conduct
- equality, diversity and inclusion
- managing contractors
- handling complaints
- internal audit
- insurance
We’ll ask you to confirm that you will:
- comply with the professional conduct rules and operational standards rules for the countries you are registered in
- update information provided in support of your registration within 28 days of it changing
- consent to some details of your registration being published

- a registration charge of £4,494
- a charge of £130 per hour for our staff to review your application
- an annual maintenance charge of £3,439 (due from the first anniversary after registration)

Before you start

If you are unsure about any of these requirements, read the guidance on this page about the regulation of RBCAs (https://www.gov.uk/guidance/register-your-business-as-a-building-control-approver#regulation-of-rbcas) under the Building Safety Act 2022, and our professional conduct and operational standards rules.

After you submit the application

We’ll review the application and if required, ask you to provide further information. You may be asked to provide copies of documentation, and you could be invited to an interview.

If all the questions are not answered on the application form, or sufficient information has not been provided, then the application will be rejected.

Getting a decision

We’ll tell you if the application is approved, approved subject to conditions, or rejected.

In cases where the application is subject to conditions or rejected, we’ll tell you why.

You can challenge the decision. The process is different depending on whether you applied to register in England, Wales, or both.

To request a review of an English registration decision, contact BSR (https://www.gov.uk/guidance/contact-the-building-safety-regulator) within 21 days of receiving your decision. You’ll need to tell us:
- your application reference
- the date the decision was made
- the reasons why you want us to review the decision
- any further information that may be relevant but was not available at the time of the original decision
If at the end of the review you are subject to conditions or rejected, you can appeal to the First-tier Tribunal.

To appeal a Welsh registration decision, you can lodge an appeal with the Magistrates’ Court within 21 days of receiving the decision. This time limit can be extended with the written agreement of BSR.

Public register

Details of each RBCA appear on the public register. The register allows people to confirm which businesses are registered as RBCAs, and the work they are registered to do.

There is one register for England and one for Wales. Your business will be included on the registers for the countries you tell us you work in.

The register shows:
- name and address of the RBCA
- the type of building control work the RBCA is registered to do
- the start and end date of registration
- details of any conditions of registration

- register of building control approvers in Wales (https://www.gov.uk/guidance/find-a-registered-building-control-approver-in-wales)
Removal from the register

An RBCA can be removed from the register if:
- the business stops carrying out regulated building control work and asks to be taken off the register
- the registration is not renewed
- the RBCA’s registration is suspended or cancelled by us
If an RBCA is removed from the register, we will continue to keep the information in line with our data retention policy.

To ask for your details to be taken off the register, call us on xx-xxxx-xxxx.

Making changes to your registration

You must notify us within 28 days of any changes relevant to the RBCA registration, which includes:
- a change of management structure
- a change of director or partner
- a change of ownership
- a change to the main contact for the RBCA
- any professional sanctions from other bodies
- any relevant unspent criminal convictions, as set out in the professional conduct rules (https://www.gov.uk/guidance/register-your-business-as-a-building-control-approver#regulation-of-rbcas), for either the business or senior personnel
- if the RBCA ceases to trade for any reason, for example insolvency
To make a change to an RBCA’s registration details, call us on xx-xxxx-xxxx. Your standard call rates will apply.

We are open Monday to Friday, 8:30am to 5pm, except Wednesdays when we are open from 10am to 5pm, and public holidays when we are closed.

We’ll ask for your email address and send you a form and a ShareFile link with instructions on how to complete and upload your changes.

You do not need to re-register the RBCA after making a change unless its registration is due to expire.

You cannot transfer an RBCA registration to another business.

OSR monitoring arrangements data returns

The OSR monitoring arrangements include a list of data that an RBCA must send to BSR after quarterly and annual periods.

An RBCA should submit operational standards rules data (https://www.gov.uk/government/publications/submitting-operational-standards-rules-data) by downloading the relevant spreadsheet template, completing it then sending to BSR by email.

Registered building inspectors

When carrying out building control work, an RBCA must consider the advice of a registered building inspector.

RBCAs must:
- employ registered building inspectors of the correct class and category for the type of building control work the RBCA does
- employ enough registered building inspectors for the building control work the RBCA is doing
- have arrangements to manage the quality of work done by registered building inspectors under supervision
There are registers of building inspectors for England and for Wales.
