The Ministry of Housing, Communities, and Local Government (MHCLG) has released an updated version of Approved Document B (Fire Safety), covering Volume 1 (Dwellings) and Volume 2 (Buildings other than dwellings) of the Building Regulations. The updated document, published on 14 January 2025, consolidates the 2019 edition, including amendments from 2020 and 2022, along with the forthcoming amendments for 2025, 2026, and 2029.
These revisions address fire safety regulations for a variety of building types, including residential homes, new and existing dwellings, flats, residential accommodation, schools, colleges, and offices. A color coding system has been introduced to clearly indicate the effective dates of the amendments.
