The Rise of Single-Tier Unitary Authorities in the UK
Unitary authorities were introduced to streamline local administration, eliminate overlapping bureaucracies, and reduce council operating costs.
All 22 local councils in Wales and all 32 local councils in Scotland operate as unitary authorities. In England, major cities and towns (such as Bristol, Plymouth, Leicester, Derby, Nottingham, and Southampton) have operated as unitaries since the late 1990s.
In recent years, the UK Government has accelerated the creation of large county-wide unitary authorities to replace historic two-tier councils.
| Former Two-Tier Area | Year Created | New Unitary Council(s) Formed |
|---|---|---|
| Buckinghamshire | 2020 | Buckinghamshire Council (Merged County + 4 Districts) |
| Northamptonshire | 2021 | West Northamptonshire & North Northamptonshire Councils |
| Cumbria | 2023 | Cumberland Council & Westmorland and Furness Council |
| North Yorkshire | 2023 | North Yorkshire Council (Merged County + 7 Districts) |
| Somerset | 2023 | Somerset Council (Merged County + 4 Districts) |
Benefits and Criticisms of the Unitary Model
For residents and property owners, the primary benefit of a unitary authority is having a single point of accountability. You never have to wonder whether the district or county council is responsible for an issue.
However, large county-wide unitary authorities (such as North Yorkshire or Cornwall) govern vast rural territories, which critics argue can make central town hall offices feel remote from rural parish communities.
When buying property in a unitary authority area, local searches are simpler and faster because all planning registers, building control files, local land charges, and highway records reside in a single database.
