A 14-week consultation on Approved Document B revisions includes new requirements for evacuation lifts and updated rules on combustible materials.. Major Revisions Proposed for Approved Document B The government has launched a crucial 14 week consultation on proposed changes to Approved Document B (ADB), the primary guidance document for fire safety in buildings. This revision, initiated on March 25, 2026, aims to integrate lessons learned from recent incidents and enhance public safety, signalling a significant shift in fire safety design and regulatory expectations. Evacuation Lifts and Combustible Materials in Focus Key proposals include mandatory requirements for evacuation lifts in residential buildings exceeding 18 metres in height. This addresses concerns about evacuating mobility impaired individuals. Additionally, revised rules on combustible materials in external walls are on the table, further tightening regulations to prevent vertical fire spread and protect building facades. Implications for Design and Construction These potential changes will have profound impacts on architects, developers, and fire engineers. Designing for evacuation lifts requires careful consideration of power supplies, fire resistance, and accessibility. Updated rules on combustible materials will necessitate rigorous material selection and testing, ensuring compliance from the earliest design stages.
