The Government has published a document listing amendments to Volumes 1 and 2 of Approved Document B which will come into effect in September 2026.
These amendments principally concern:
- Threshold for the provision of a second staircase in blocks of flats with a storey 18m or more in height.
- Evacuation shafts are introduced to support the provision of evacuation lifts.
- Changes to provisions for fire doorsets.
- New terminology including definitions for evacuation shaft, evacuation lift lobby, interlocked stair and storey exit.
- Provisions for horizontal escape and vertical escape separated as per the structure of Volume 2.
The 2019 edition incorporating the 2020 and 2022 amendments will continue to apply where a building notice or an initial notice has been given to, or a building control approval application with full plans made to, the relevant authority before 30 September 2026 and either the building work to which it relates:
- has started and is sufficiently progressed before that day; or
- is started and is sufficiently progressed within the period of 18 months beginning on that day
