On 18 June 2025, the Welsh Government published the Draft Planning (Wales) Bill, a major step toward simplifying and modernising planning legislation in Wales.

Why is reform needed?

Planning law in Wales has long been criticised for being fragmented, outdated, and difficult to navigate. Much of it is based on UK legislation that has been amended repeatedly over the decades, often without consolidation. This has resulted in a complex system, largely available only in English, creating barriers for both professionals and the public.

Key Features of the Draft Bill

It is important to note the new Bill is a consolidation of existing law which doesn't change planning law or change planning policy, however its impact will be significant. The Bill is expected to introduce:

• Modernised Structure: New numbering system for orders. This system differs from the established framework used under the Town and Country Planning Act (TCPA).  For example, Section 106 Agreements (planning obligations) under the TCPA are currently anticipated to become Section 165 Agreements.
• Updated Language: Terms like “material considerations” to become “relevant considerations” and “local planning authorities” and “minerals planning authorities” to become simply “planning authorities”.
• Clarified Definitions: Definitions such as “development” are restated in clearer, modern terms. Removes outdated phrases like “deemed applications”.
• National and Local Development Plans: Clearer hierarchy and delineation of roles among development plans, including the National Development Framework, emerging Strategic Development Plans, and Local Development Plans. It also removes outdated references to obsolete plan types.
• Tree and Woodland Protection: Incorporates provisions from the Planning Act 2008 for the preservation of trees and woodland, with new regulations expected alongside the Bill's implementation.
• Minerals and Waste: Consolidates regulations into a single, coherent framework.

Next Steps

The Bill is expected to be introduced to the Senedd in September 2025, followed by scrutiny, consultation and potential amendments. Stakeholders are encouraged to engage with the process.

A second Bill, the Planning (Consequential Provisions) (Wales) Bill, will accompany the main Bill to address repeals, amendments, and transitional arrangements.

Getting ready for changes

By preparing early, planning professionals can ensure they are ready to operate effectively within the new legal landscape. They may wish to consider the following:

• Engage in the Legislative Process: Participate in consultations and provide feedback during the Senedd scrutiny process to help shape the final legislation.
• Monitor Transitional Provisions: Keep up to date with the accompanying Planning (Consequential Provisions) (Wales) Bill, which will outline how existing permissions and procedures will transition.
• Review Internal Processes: Familiarise themselves with the proposed changes to structure, terminology, and legislative references.
• Update Guidance and Templates: Identify any internal documents, checklists, letters or standard procedures that may need revision once the Bill is enacted.

Conclusion

The Draft Planning (Wales) Bill represents a significant milestone in Welsh legal reform. By consolidating decades of legislation into a single, accessible framework, it aims to reduce complexity and improve clarity. While it doesn't change planning law, it is expected to reshape how planning law is understood and applied in Wales.
