# Unitary authorities of England

In England, a unitary authority or unitary council is a type of local authority responsible for all local government services in an area. They combine the functions of a non-metropolitan county council and a non-metropolitan district council, which elsewhere in England provide two tiers of local government.
The district that is governed by a unitary authority is commonly referred to as a unitary authority area or unitary area. The terms unitary district and, for those which are coterminous with a county, unitary county are also sometimes used. The term unitary authority is also sometimes used to refer to the area governed, such as in the ISO 3166-2:GB standard defining a taxonomy for subdivisions of the UK, and in colloquial usage.
Unitary authorities are constituted under the Local Government Act 1992, which amended the Local Government Act 1972 to allow the existence of non-metropolitan counties that do not have multiple districts. Most were established during the 1990s, with more created in 2009 and 2019–23. The size of the areas governed by unitary authorities varies greatly; the authorities created in the 1990s were generally created from single districts and covered a single large town or city, while those created since 2009 often cover entire non-metropolitan counties.
In addition to the authorities created under the 1992 act, the term unitary authority has also been used in a broader sense that is inclusive of all single-tier councils, such as those for London boroughs and metropolitan boroughs.

## History
### Background

The term "unitary authority" was first used in the Redcliffe-Maud Report in 1969 in its current sense of a local government authority which combines the functions of a county council and a district council. Strictly speaking, the term does not necessarily mean a single level of local government within an area, because in some cases there are also parish councils in the same area.
Although the term was not applied to them, county boroughs between 1889 and 1974 were effectively unitary authority areas, that is, single-tier administrative units. Before 1889, local government authorities had different powers and functions, but from medieval times some cities and towns had a high degree of autonomy as counties corporate. Some smaller settlements also enjoyed some degree of autonomy from regular administration as boroughs or liberties.
The Local Government Act 1972 created areas for local government where large towns and their rural hinterlands were administered together. The concept of unitary units was abandoned with a two-tier arrangement of county and district councils in all areas of England, except the Isles of Scilly where the small size and distance from the mainland made it impractical. In 1986 a broadly unitary system of local government was introduced in the six metropolitan counties and Greater London, where the upper-tier authorities were abolished and their functions were split between central government, the borough councils and joint boards.

### 1990s reform

A review in the 1990s was initiated to select non-metropolitan areas where new unitary authorities could be created. The resulting structural changes were implemented between 1995 and 1998. Bristol, Herefordshire, the Isle of Wight and Rutland were established as counties of a single district; the county administration of Berkshire was dissolved, though the county legally preserved to retain for its territory its royal designation, and each of its district councils became unitary; the counties of Avon, Humberside and Cleveland were broken up to create several unitary authorities; and a number of districts were split off from their associated counties. The changes caused the ceremonial counties to be defined separately, as they had been before 1974. The review caused 46 unitary authorities to be created.

### 2009 changes

A further review was initiated in 2007 and was enacted in 2009. The review established Cornwall and Northumberland as counties of a single district; established unitary authorities in County Durham, Shropshire and Wiltshire covering the part of the county that was not already split off in the 1990s review; and divided the remainder of Bedfordshire and Cheshire into two unitary authority areas. The review caused nine unitary authorities to be created.

### Further reform and 2019−2023 changes

In 2017, it was proposed that two unitary authority areas be formed to cover the ceremonial county of Dorset. One of the authorities would consist of the existing unitary authorities of Bournemouth, Poole and the non-metropolitan district of Christchurch, the other would be composed of the remainder of the county. In November 2017, Secretary of State for Communities and Local Government, Sajid Javid stated that he was "minded to approve the proposals" and a final decision to implement the two unitary authority model was confirmed in February 2018. Statutory instruments for the creation of two unitary authorities, to be named Bournemouth, Christchurch and Poole Council and Dorset Council, have been made and shadow authorities for the new council areas were formed ahead of their creation on 1 April 2019.
Buckinghamshire County Council and the non-metropolitan districts of Aylesbury Vale, Chiltern, South Bucks, and Wycombe in Buckinghamshire were replaced by a single unitary authority known as Buckinghamshire Council on 1 April 2020. The existing unitary authority of Milton Keynes was not affected; from 1 April 2020, therefore, the ceremonial county of Buckinghamshire has been composed of two unitary authority areas.
In March 2018, an independent report commissioned by the Secretary of State for Housing, Communities and Local Government, proposed structural changes to local government in Northamptonshire. These changes would see the existing county council and district councils abolished and two new unitary authorities created in their place. One authority, West Northamptonshire, would consist of the existing districts of Daventry, Northampton and South Northamptonshire and the other authority, North Northamptonshire would consist of Corby, East Northamptonshire, Kettering and Wellingborough districts. This was confirmed in May 2019, with the new councils being created in April 2021.
In July 2021 the Ministry of Housing, Communities and Local Government announced that in April 2023, the non-metropolitan counties of Cumbria, North Yorkshire and Somerset would be reorganised into unitary authority areas. The new authorities, Cumberland, Westmorland and Furness, North Yorkshire Council and Somerset Council were first elected in May 2022 and formally assumed their powers on 1 April 2023.

### English Devolution Bill

The Labour Party returned to power following the 2024 general election, and in her Autumn budget statement, Chancellor of the Exchequer Rachel Reeves outlined that a forthcoming English Devolution Bill would include plans for "working with councils to move to simpler structures that make sense for their local areas", suggesting that a new round of local government reorganisation could be likely.
In February 2025 Jim McMahon, the Minister for Local Government and English Devolution, wrote to all two-tier and unitary councils in England stating that all local government will move to a unitary system with new council areas having a target population of at least 500,000. Councils were invited to work together and submit an interim plan by 21 March 2025 and a final proposal for reorganisation by 28 November 2025.

## Restructuring

The process of changing from a two-tier local government to a structure based on unitary authorities is called 'restructuring'. The Secretary of State responsible for local government invites proposals from local areas to restructure into unitary authorities, and the Secretary decides whether or not the change should be implemented. The restructuring is carried out by an Order. There are no examples in the UK of councils restructuring back into a two-tier system.

## Functions

Unitary authorities combine the powers and functions that are normally delivered separately by the councils of non-metropolitan counties and non-metropolitan districts. These functions are housing, waste management, waste collection, council tax collection, education, libraries, social services, transport, planning, consumer protection, licensing, cemeteries and crematoria. The breakdown of these services is as follows:
| Service | Non-metropolitan county | Non-metropolitan district | Unitary authority |
| Education | Y | | Y |
| Housing | | Y | Y |
| Planning applications | | Y | Y |
| Strategic planning | Y | | Y |
| Transport planning | Y | | Y |
| Passenger transport | Y | | Y |
| Highways | Y | | Y |
| Fire | Y | | Y |
| Social services | Y | | Y |
| Libraries | Y | | Y |
| Leisure and recreation | | Y | Y |
| Waste collection | | Y | Y |
| Waste disposal | Y | | Y |
| Environmental health | | Y | Y |
| Revenue collection | | Y | Y |

## Criticism

Unitary government has been criticised for damaging local democracy. Opponents to unitary authority criticise the 'bigger is better' assumption and highlight that larger councils breed mistrust of councillors and reduction in public engagement and voter turnout. Outside the UK, multi-level local government is the prevailing system, with major towns normally having a local authority. The average size of a local authority in England is 170,000, three times that of Europe.

## Electoral arrangements

Most unitary authority areas are divided into a number of multiple member wards from which councillors are elected in the same way as in two-tier district council elections. The exceptions, which are divided into electoral divisions as in county council elections, are Cornwall, County Durham, the Isle of Wight, Northumberland, Shropshire and Wiltshire.

## Current list

Districts are usually named after a town, city, geographical area or county (historic and or ceremonial). With no effect on powers or functions, districts can have the status of royal borough, borough or city. A district having a charter is dependent on the charter's wording: as a charter trustee to a place in the district; having joint charter to the place and district or to the district itself.

Notes

## Former unitary authorities

| Area | Authority | Created | Dissolved | Ceremonial County | Replaced by |
| Bournemouth | Bournemouth Borough Council | 1997 | 2019 | Dorset | Bournemouth, Christchurch and Poole |
| Poole | Poole Borough Council | 1997 | 2019 | Dorset | Bournemouth, Christchurch and Poole |

## Similar authorities

The Council of the Isles of Scilly is a sui generis single-tier authority, created in 1890 and since 1930 has held the "powers, duties and liabilities" of a county council. It thus does not fit the narrower definition of unitary authority as those authorities created under the Local Government Act 1992. The 36 metropolitan borough councils are also the sole elected local government units in their areas (except for parish councils in a few locations), but share strategic functions with joint boards and arrangements. On the other hand, the City of London Corporation and the 32 London borough councils, although they have a high degree of autonomy, share strategic functions with the directly elected Mayor of London and London Assembly.

## Combined authorities

Unitary authorities should not be confused with another formation in English local government, the combined authority.
