Higher-risk buildings—new regulations for Wales (The Building (Higher-Risk Buildings Procedures) (Wales) Regulations 2025)
Construction analysis: The Building (Higher-Risk Buildings Procedures) (Wales) Regulations 2025, SI 2025 No 1321 (the Regulations) bring into force the detailed procedural regime governing the design, construction and completion of higher-risk buildings in Wales. The Regulations give procedural effect in Wales to the higher risk buildings (HRB) regime created under Part 3 of the Building Safety Act 2022 (BSA 2022), as adapted for the Welsh building control system. This article summarises what the Regulations introduce in practical terms, including the mandatory gateway approval process, enhanced information and declaration requirements, controls on design and construction changes, and prohibitions on starting work or occupying an HRB without regulatory approval. It focuses on how the Welsh Regulations operate, on whom obligations are imposed, when they apply, and the legal consequences of non-compliance, with reference where relevant to the equivalent regime in England.
