Approved Document Part B Amendments

Recent amendments to the government’s Approved Document Part B: Fire Safety document will have implications for building services design. One of these amendments reduces the requirement for sprinklers in blocks of flats with a top storey of more than 30m down to 11m above ground level.

Additional amendments cover wayfinding signage for the service in addition to the resisting of fire spread from one building to another. The amendments outlined in May will take effect in November 2020. The full list of amendments can be found here.
