The Sussex and Brighton Combined County Authority Regulations 2026

Published: Wed 25th Mar 26

These Regulations establish the Sussex and Brighton Combined County Authority (CCA), encompassing Brighton and Hove City Council, East Sussex County Council, and West Sussex County Council, as a body corporate effective from the date the regulations were made, with mayoral functions commencing from May 2028.

The CCA is granted concurrent functions related to local transport planning, data sharing for crime reduction, and economic development, alongside powers for the authority to pay grants.

The regulations define the constitution of the CCA, mandate its funding through contributions from constituent councils based on population share, and set out the election cycle, term of office, and executive powers of the directly elected Mayor.

Arguments For

  • Establishes a unified governance structure (CCA) for Brighton and Hove, East Sussex, and West Sussex, aiming to improve economic, social, and environmental well-being across the region, as mandated by the 2023 Act.

  • Centralizes key transport planning functions (Local Transport Plans) under the CCA, ensuring coordinated regional strategy and potentially leading to operational efficiencies and cost reductions in the public sector.

  • Introduces a directly elected Mayor in 2028 with specific executive powers over transport planning and grant-making, providing clear regional leadership and accountability for these functions.

  • Ensures financial stability by mandating that constituent councils fund the CCA's operational costs based on resident population proportions, subject to mayoral expenditure agreements.

  • Grants the CCA concurrent powers for data sharing concerning crime and disorder reduction, and general competence for economic development and regeneration, supporting integrated policy delivery.

Arguments Against

  • Shifts existing statutory functions from established local authorities (the constituent councils) to a new corporate body, potentially creating bureaucratic overlap or governance complexity during the transition period before the Mayor's election in 2028.

  • The initial funding model relies on mandatory contributions from constituent councils based on population, which may cause financial strain if agreed-upon cost allocations or mayoral expenditure proposals are contested.

  • Introducing a politically restricted role (Mayor's Political Adviser) under the CCA structure mirrors existing local government rules but adds another layer of political staffing potentially increasing administrative overhead.

  • Key mayoral functions related to transport and grant-making only become active after the 2028 election (Part 5 commencement), meaning the initial multi-council structure operates with limited executive powers.

  • The process requires the constituent councils to consent to the regulations, which might represent a compromise where individual council priorities are subsumed under a broader, externally driven regional agenda.

EXPLANATORY NOTE

(This note is not part of the Regulations)

These Regulations establish the Sussex and Brighton Combined County Authority ('the Combined County Authority') and confer certain functions of local authorities and other public authorities on the Combined County Authority.

The Levelling-up and Regeneration Act 2023 (c. 55) provides for the establishment of combined county authorities for the areas of two or more local authorities in England. Combined county authorities are bodies corporate which may be given power to exercise specified functions in their area.

Part 2 establishes the new Combined County Authority for the local government areas of Brighton and Hove City Council, East Sussex County Council and West Sussex County Council and makes provision for its constitution (in the Schedule).

Part 3 provides for the election of the mayor and for the appointment of a political adviser to the mayor.

Part 4 confers on the Combined County Authority functions relating to transport. It transfers functions relating to local transport planning from the local authorities to the Combined County Authority and confers powers for the mayor to pay grants.

Part 5 sets out the functions of the Combined County Authority which are to be only exercisable by the mayor and makes provision in relation to joint committees.

Part 6 makes provision for the funding, by the constituent councils, of those costs of the Combined County Authority that relate to the exercise of its functions.

Part 7 confers additional functions to be exercisable by the Combined County Authority concurrently with the constituent councils, including functions relating to economic development and data sharing.

A full regulatory impact assessment has not been prepared as this instrument will have no impact on the costs of the business and voluntary sectors. The impact on the public sector is that conferring functions on the Combined County Authority should lead to operational efficiencies that could lead to reduced costs.
