Selecting Unitary Authority Options for West Sussex

The video below discusses the most efficient, democratic and cost effective way for West Sussex to re-organise from a two-tier local Government model to a single tier Unitary Authority model that is highly efficient and saves the most in Council Tax.



Notes on Supporting Data

The creation of this video required a number of calculations and data - key to this is that a £6 million increase or decrease in spending is equivalent to 1% on County Council Tax - this was accurate when calculating the County Council tax for the 2025.26 budget. 

The most recent annual budget figures show the budget for West Sussex County Council is £2,226 million. The sum for all District and Borough Councils when added together is £179 million. 

The figures quoted are based on a 2025 analysis conducted by Price Waterhouse Cooper  HERE is the link to the amalgamated analysis. The numbers from the Sussex part of the analysis that were used in the video are reproduced below. 

Single Unitary Authority
(to the nearest £million)

Five Year Impact of Disaggregation                     £0        
Net Benefit after Five Years                                  £125 million
Recurring (annual) Benefit after Five Years       £30 million


Two Unitary Authorities
(to the nearest £million)

Five Year Impact of Disaggregation                    - £104 million (this is a cost!)
Net Benefit after Five Years                                    £21 million
Recurring (annual) Benefit after Five Years         £11 million

The impact of a three unitary model was not mentioned. However, it's reproduced below. 

Three Unitary Authorities
(to the nearest £million)

Five Year Impact of Disaggregation                    - £173 million (this is a cost!)
Net Benefit after Five Years                                 - £48 million (this is a cost!)
Recurring (annual) Benefit after Five Years      - £2 million (this is a cost!)


Here is the transcript from the video. 


"Hello, I'm Andy McGregor West Sussex County Councillor and Adur District Councillor and I'm going to speak about the 21% saving £374 pounds a band D taxpayer would save if we adopt a single Unitary Authority for West Sussex. 

However,
the saving would just be 3.5% £63 pounds if a two unitary authority model is adopted. Why the big difference? It's all down to council spending. Council spending is £2,405 million pounds a year. The objective of the government's devolution project is to bring this down by being more efficient and effective by moving from two tiers of local government to one.

And
if we have a look at this simple pie chart, West Sussex spending on council services is £2,226 million (blue) and makes up 92.6% of all council spending. The seven Districts and Boroughs spend the other £179 million (red).

Significant
savings will be made by aggregating the services provided by the District and Borough councils. However, splitting the council in two doesn't simply divide the spending into two equal halves. There will be a dis-aggregation cost if the services provided by the council are split in two. That simple pen stroke is estimated to cost £104 million in the first five years. £311 for that Band D council tax payer.

Then
there's the ongoing costs of two chief executives, two boards of directors two heads of service, two sets of offices, two groups of councillors, etc, etc, etc. The difference is £20 million a year - yet another £60 on the bill every year of that hard pressed band D council tax payer.

And
all the District and Borough councils are Labour or Liberal Democrat controlled. And all of them are recommending the two Unitary model for West Sussex. They say a Unitary Authority of 870,000 people covering the whole of West Sussex is too big.

However,
when quizzed on the subject at a recent debate, the Labour leader of Adur District Council could only say that we should look at the example of big Unitary Authorities like Birmingham and shy away. However, West Sussex is not Birmingham. We're in the affluent South East. We have a very different economy An economy where the Conservative controlled county council have balanced the books for 92.6% of council spending for many years.

When
presented with the figures, I've told you the Labour leader of Adur defended the two unitary authority model by saying the services like schools, education, social services adult services children's services libraries, etc, etc could possibly remain as a single department and serve both unitary authorities.

For
a start. I think this is just a guess, maybe a hope. A department with two masters could easily be pulled in two different directions by differences in council policies. I don't think it would work, and neither do many others.

Why
not simply retain the departments as they are in West Sussex? Single departments servicing the whole of West Sussex in a single Unitary Authority. To keep things at peak efficiency - and make the big savings by aggregating the services provided by the Districts and Boroughs into a single Unitary Authority. Something I've wondered myself.

The
simple answer is that Labour and the Liberal Democrats are, I suspect, playing political games and, as is the habit of parties of the left planning to waste our money on their ideas.


West Sussex councils have submitted their draft interim plan for Local Government Reorganisation (LGR) to the Minister for Local Government and English Devolution, Jim McMahon, outlining their progress and seeking guidance on several critical issues to ensure a successful final submission in September 2025.

Click on the shield above to read that proposal in full. 

The interim plan, submitted by West Sussex Leaders and Chief Executives, emphasises the councils' commitment to devolution and a route map for creating unitary authorities that will deliver the best outcomes for citizens. The interim plan outlines potential options for new council structures. It also highlights the opportunity for public service reform and improved outcomes, particularly in areas such as homelessness prevention and social care.


The councils have also proposed how to address democratic representation, governance arrangements, and how new structures will support devolution ambitions. While acknowledging limited local engagement due to the tight timeline, they have committed to extensive consultation with local residents, businesses and wider stakeholders as proposals develop.

Indicative costs for preparing proposals and implementation have been provided, along with arrangements for inter-council cooperation and decision-making.

However, several key questions remain that require clarification from the government. Chief amongst these is the size and boundaries of potential new unitary authorities, particularly concerning any required expansion of Brighton & Hove. In addition, guidance is sought on how Crawley fits the unitarisation and devolution agenda given its strong economic links to Surrey. The councils are seeking clear guidelines on population size limits, funding, timelines, and the impact of the Devolution Bill.

"We are making good progress, but we need clarity on these issues to avoid costly delays and ensure we develop the most effective structures for our communities," said Michael Jones, Leader of Crawley Borough Council on behalf of the West Sussex Leaders. "We are committed to working collaboratively to create a shared evidence base and develop proposals that reflect the unique needs of our area."

"We are excited about the opportunities that LGR brings for public service reform and delivering significant improvements for local communities," Michael Jones added. "We are working diligently to ensure a smooth transition and a positive legacy for West Sussex."

The councils are seeking urgent answers to their questions from the government to maintain momentum and ensure a robust final submission in September.

Next Step - Interim Plan Submission by 21st March 2025

Jim McMahon OBE MP Minister of State for Local Government and English Devolution has written letters to Councils in the first tranche of devolution.

Links to the full letters are on the right. The part outlining the next step is pasted below. 

Interim plans

An interim plan should be provided to government on or before 21 March 2025. This should set out your progress on developing proposals in line with the criteria and guidance. The level of detail that is possible at this stage may vary from place to place but the expectation is that one interim plan is jointly submitted by all councils in the area. It may be the case that the interim plan describes more than one potential proposal for your area, if there is more than one option under consideration. The interim plan should:

a) identify any barriers or challenges where further clarity or support would be helpful.

b) identify the likely options for the size and boundaries of new councils that will offer the best structures for delivery of high-quality and sustainable public services across the area, along with indicative efficiency saving opportunities.

c) include indicative costs and arrangements in relation to any options including planning for future service transformation opportunities.

d) include early views as to the councillor numbers that will ensure both effective democratic representation for all parts of the area, and also effective governance and decision-making arrangements which will balance the unique needs of your cities, towns, rural and coastal areas, in line with the Local Government Boundary Commission for England guidance.

e) include early views on how new structures will support devolution ambitions.

f) include a summary of local engagement that has been undertaken and any views expressed, along with your further plans for wide local engagement to help shape your developing proposals.

g) set out indicative costs of preparing proposals and standing up an implementation team as well as any arrangements proposed to coordinate potential capacity funding across the area.

h) set out any voluntary arrangements that have been agreed to keep all councils involved in discussions as this work moves forward and to help balance the decisions needed now to maintain service delivery and ensure value for money for council taxpayers, with those key decisions that will affect the future success of any new councils in the area.

Update 5th February 2025

It has now been confirmed that West Sussex County Council, East Sussex County Council and Brighton and Hove City Council will form part of the first tranche of newly devolved authorities. 

Please note, some of the below is an estimate or best prediction at this time. For example, we do not know the results of the public consultation - which will help shape the unitary authorities. This blog will be updated with any news, as it happens. 

Here's a top-line summary based on the announcement on 5th February 2025;

Starting Just About Immediately - Consultation on new Unitary Authorities.

Autumn 2025 - the Government is expected to announce that the 2026 elections will only be for the Mayor of the new Mayoral Authority.

?????? - At some time the results of the consultation will be announced. Along with the agreed boundaries of the new Unitary Authorities.

May 2026 - Election of Mayor

May 2027 - Elections for Councillors to the new Unitary Authorities.

May 2027-2028 The District/Boroughs/County Councils will run concurrently until May 2028 when those authorities will be dissolved.

N.B. The 5th February 2025 press release states:

"Following an expression of interest from the leaders of West Sussex County Council, Brighton & Hove City Council, and East Sussex County Council, ministers have approved proposals to create a mayoral strategic authority for Sussex, made up of an elected mayor and two members of each constituent authority, with strategic powers for transport, public safety, health, environment and climate change, housing, economic growth, skills and jobs."

For the first year of the Mayoral Authority is it expected that the "two members of each constituent authority" will be selected from the existing upper tier local authorities, West Sussex County Council, East Sussex County Council and Brighton and Hove City Council. It is expected that these will be replaced by representatives of the new Unitary Authorities when elected in May 2027.

Here is the press release from West Sussex County Council in full;


An opportunity to gain new powers and investment for Sussex has moved a step nearer with the government’s agreement to make the area a priority for devolution.

Following an expression of interest from the leaders of West Sussex County Council, Brighton & Hove City Council, and East Sussex County Council, ministers have approved proposals to create a mayoral strategic authority for Sussex, made up of an elected mayor and two members of each constituent authority, with strategic powers for transport, public safety, health, environment and climate change, housing, economic growth, skills and jobs.

As well as unlocking new powers and investment for the region, it would give the people of Sussex a stronger voice in how national decisions affect them and enable more decisions to be taken locally.

The government will now begin a consultation to seek the views of people and organisations in Sussex.

All three of Sussex’s upper-tier local authorities – Brighton & Hove City Council, East Sussex County Council and West Sussex County Council – agree that devolution could unlock new funding and give people a stronger voice over national decisions which affect them and greater power to steer major projects across the area.

It follows the Government’s White Paper on English Devolution published in December which outlined its aim to bring more decision-making down from Westminster to local communities.

Cllr Paul Marshall, Leader of West Sussex County Council, said: “This is fantastic news for the whole of Sussex and West Sussex in particular. A mayoral authority will give our communities greater influence in the big decisions that affect the region, such as our highways, housing, and economic growth, plus much-needed long-term financial stability.

"I’m pleased the government has accepted us on to its priority programme, meaning we can unlock these benefits sooner rather than later. There is much to do, but please be assured we will continue our focus on delivering essential services and putting the needs of our residents first.”

Cllr Keith Glazier, Leader of East Sussex County Council said: “I believe this is excellent news for the people of Sussex because it’s an opportunity for more decisions to be made locally and for greater investment here. I’m pleased the government has recognised our potential to prosper and develop together.”

Cllr Bella Sankey, Leader of Brighton & Hove City Council, said: “This is an historic and exciting moment for our region. I am optimistic and ambitious about devolution because of the direct benefits I know it will bring to all communities in Sussex.

"It will mean that more money is directly invested in our area and that better transport, affordable housing and skills and job creation can be accelerated. I’m looking forward to meeting with residents, businesses and partners to ensure that all of our communities have the opportunity to shape the future.”

Local councils in every part of Sussex would work closely with the mayoral strategic authority and would continue to deliver day-to-day services.

Alongside devolution, the government is asking for proposals for unitary councils in all parts of Sussex, moving away from the two-tier model of county and borough or district councils where those exist.  Discussion with partners will continue on how this might be arranged.

There are no immediate changes to the operation of local authorities in Sussex or the services they provide.
