Local government reorganisation
Local government reorganisation refers to the creation of unitary authorities in place of district, borough and county councils.
Latest news
West Sussex councils have reached a significant milestone in the journey towards reshaping local government. A business case for local government reorganisation has now been completed and will be presented at council meetings across the county, districts, and boroughs towards the end of September. The business case is set to be discussed at Horsham District Council's Cabinet Meeting on Wednesday 24 September at 7pm. Find more information, including the business case and appendix pack here.
This marks a key step in the collaborative effort of all councils to respond to the government’s requirement to re-structure local government and create a simpler structure for local government.
Councils will submit a letter to central government on 26 September proposing their preferred option for local government in West Sussex.
Once submitted, the government will undertake consultation and a final decision from government is anticipated in Spring 2026. We would like to extend our thanks to the thousands of residents, businesses, community groups and council staff who took part in the recent Shaping West Sussex engagement survey. Your feedback has been vital in shaping the proposals and ensuring they reflect the priorities of our communities.
Your feedback
Residents, businesses and community groups across the county were invited to share their views about options for local government reorganisation in West Sussex through a public survey which ran from 17 July to 13 August.
The survey asked respondents about where they live or work, the council services they use, as well as their thoughts about how their council could be structured in the future. Paper copies and large print versions of the survey were available at all West Sussex Libraries, District, Borough and County Council receptions and additional support was provided through customer service teams.
The feedback gathered has been used to inform the shared business case for West Sussex councils.
Further opportunities to get involved
Once the business case has been submitted on 26 September 2025, the Government will begin a formal consultation process. A Government decision on local government reorganisation in West Sussex is expected in spring 2026.
The Ministry of Housing, Communities & Local Government has issued a summary of the local government reorganisation process. This gives more information about the formal consultation process and expected timelines.
Further engagement will follow in line with the chosen model and implementation schedule. This is a significant change that will affect how local services are run in the future – and how decisions are made about the things that matter most to you. That’s why it’s vital that residents, businesses and community groups continue to get involved throughout the process.
The background to local government reorganisation in West Sussex
On 16 December 2024 the Government issued an English Devolution White Paper. This paper asked for County Councils to join together to make proposals to be a Mayoral Combined Authority. West Sussex County Council, Brighton and Hove City Council and East Sussex County Council have told the Government they think the Combined Authority should cover the whole existing area of Sussex. The Government has agreed to progress this proposal onto a fast-track programme, (known as the Devolution Priority Programme). It is likely the new strategic authority would be created in March 2026 and mayoral elections would be held in May 2026.
The White Paper also asked two-tier authorities to reorganise into a single-tier of local government. In our area this means Horsham District Council and West Sussex County Council would cease to exist and a new council – called a Unitary Authority - covering all their main services would take their place. The Government has said the new council must provide new services to a minimum of 500,000 residents. This means the new Unitary Authority would cover several current district council areas at least. Which areas these would be isn’t yet decided. It is likely this new Unitary Authority council would be elected in May 2027 and start on 1 April 2028.
On 21 March 2025, West Sussex councils submitted their draft interim plan for Local Government Reorganisation (LGR) to the Minister for Local Government and English Devolution, Jim McMahon. This submission outlines progress and seeks guidance on several critical issues to ensure a successful final submission in September 2025.
West Sussex Councils received a response letter on 7 May 2025, which you can read here.

Devolution is the transfer of powers and funding from national to local government. Local Government Reorganisation is about how the powers and funding that sit with local government are organised between councils.
No. As far as we are concerned, it is business as usual, and we will continue to support our communities to the high standards that they expect. We will just need to carefully consider any long-term decisions that may impact on any future reorganisation.
All current authorities in Sussex will cease to exist on the transfer date and all staff will move across to the newly formed authority.
All services provided by county, unitary, district and borough councils will continue. There may also be some services that are currently delivered by county, unitary, district and borough councils that may transfer to the new strategic authority.
If Local Government Reorganisation takes place, then Horsham District Council will no longer be an entity once the new Unitary Authority is established. However, councillors will be able to put themselves forward as candidates for the new authority.
If the Government decides to go ahead with Local Government Reorganisation then a Structural Order will be laid in Parliament. This will set out in detail what will happen to all assets and liabilities, including reserves, for all of the councils merging to form the new unitary council. Where other local government reorganisations have taken place, assets, liabilities and reserves were not ringfenced.
Existing town and parish councils will remain. When a new large council (Unitary Authority) is set up in this way it is usual to transfer some services that are very local to the towns and parishes. These services and facilities may include parks, open spaces, war memorials, public toilets, playgrounds, community halls and community libraries.
The Leader and Chief Executive of Horsham District Council started visiting the larger parishes in Horsham District throughout February and March this year to start the conversation about whether these facilities could be run locally by them.
