UK Enacts Spatial Development Provisions from Planning and Devolution Acts

The UK government, through The Planning and Infrastructure Act 2025 (Commencement No. 5) and English Devolution and Community Empowerment Act 2026 (Commencement No. 5) Regulations 2026, has brought into force specific provisions relating to spatial development strategies.

This marks a crucial step in the implementation of two significant pieces of legislation, signalling the activation of new powers and duties concerning strategic land use planning across England. For practitioners, businesses, and the public, the commencement of these provisions means that spatial development strategies will now play an active role in shaping future development, infrastructure projects, and environmental considerations at a regional or sub-regional level. This will influence decisions on housing, transport, economic growth, and environmental protection, requiring a more integrated and strategic approach to planning than previously. The phased commencement of such major Acts is typical for complex legislative reforms, indicating an ongoing evolution of the legal landscape.

The legal context for these Regulations lies within the Planning and Infrastructure Act 2025 (c. 34) and the English Devolution and Community Empowerment Act 2026 (c. 23). Commencement regulations are statutory instruments designed to bring into force parts of an Act of Parliament that were not immediately effective upon receiving Royal Assent. Spatial development strategies are a key component of the English planning system, providing a strategic framework that guides local plans and development decisions across wider geographical areas, often overseen by combined authorities or other strategic bodies. This legislative action reflects the government's ongoing efforts to reform the planning system, promote devolution, and empower local communities in shaping their environments.

Key parties involved include the UK government, particularly the Department for Levelling Up, Housing and Communities, which is responsible for planning policy, as well as local planning authorities, combined authorities, developers, infrastructure providers, and environmental organisations. These regulations directly impact how these entities will plan for and execute development projects, requiring adherence to the newly activated provisions concerning spatial development strategies. The regulations themselves are statutory instruments, forming part of the secondary legislation that gives effect to the primary Acts.

Practitioners in planning law, property development, and local government must immediately familiarise themselves with the newly commenced provisions regarding spatial development strategies. This includes understanding their scope, legal weight, and the process for their formulation and adoption, as these strategies will significantly influence future planning applications, infrastructure investment, and land use decisions. Developers and businesses involved in land acquisition or large-scale projects should assess how these strategies will impact their long-term plans and engage proactively with relevant planning authorities. Continuous monitoring of further commencement regulations for both the 2025 and 2026 Acts is essential, as additional provisions will continue to come into force, further shaping the legal and regulatory environment.
