The UK government confirmed on 16 July 2026 that Oxfordshire and part of Berkshire will be split into three new unitary authorities, replacing the seven existing councils across the two areas. The announcement came on the day Parliament rose for its summer recess.

The three new councils — Greater Oxford Council, Northern Oxfordshire Council, and Ridgeway Council — will be established on 1 April 2028, when the existing councils are abolished. Elections for the new authorities are expected to take place in May 2027, giving roughly a year for shadow arrangements before full cutover.

The restructuring affects a complex landscape of existing councils. Oxfordshire alone currently operates with six: one county council, one city council, and four district councils. West Berkshire Council, which sits across the county boundary in Berkshire, brings the total to seven.

The new structure groups them into three units. Greater Oxford Council will cover the city and its Green Belt area. Northern Oxfordshire Council will take in the existing Cherwell and West Oxfordshire districts. Ridgeway Council will cover most of the existing South Oxfordshire area, including Vale of White Horse. The named councils were confirmed in the government's announcement and reported by Oxfordshire County Council's news service and South Oxfordshire District Council.

The process that led here has been neither quick nor straightforward. Oxfordshire and West Berkshire councils submitted three different proposals to the government in November 2025, according to the 3councils.org joint proposal site. A public consultation then ran from 5 February to 26 March 2026. The three-unitary model was led by Oxford City Council, which argued for a structure centred on the city and its surrounding Green Belt rather than a single county-wide authority.

The BBC reported the confirmed outcome on 20 July 2026, categorising the story under its Oxfordshire subsection. The report noted the range of councils affected, including Oxfordshire County Council, West Berkshire Council, Vale of White Horse District Council, Cherwell District Council, West Oxfordshire District Council, and South Oxfordshire District Council.

For those working in local government, the timeline is the immediate operational concern. Between now and May 2027, existing councils must continue delivering services while preparing for elections to bodies that do not yet exist. After those elections, shadow authorities will need to stand up governance, staffing, IT, and service-delivery arrangements ahead of the 1 April 2028 vesting date. The transition period — from election to vesting — is under twelve months.

The abolition of seven councils and creation of three is a net reduction of four authorities. Staff transfer, asset allocation, and debt apportionment between the successor bodies are likely to consume the bulk of the transition programme. Council leaders will also need to navigate the politics of naming, boundary settlements, and headquarters locations, all of which tend to generate more heat than light.

This is the latest in the wider programme of local government reorganisation driven by ministers, who have made unitary status a condition of accessing devolution deals. The Oxfordshire and Berkshire changes sit alongside similar reorganisations being pursued across other parts of England.

The announcement's timing on the day of recess is a familiar Westminster move. MPs departed on 16 July, leaving local council officers and members to digest the detail over the summer without the backdrop of parliamentary scrutiny. When the House returns, the focus shifts to the practical machinery of implementation.
