Q

What is the current status of the change in regulation for Document B?

A

DLUHC on the 29th March 2024 released proposed amendments to Document B which propose that all new residential buildings over 18m will require a second staircase

These changes shall come into place on the 30 September 2026. Any new building that submits an initial notice ahead of this date is not subject to the amendments.

The second staircase does not need to include an evacuation lift, as following a cost benefit analysis which highlighted the net impact of including an evacuation lift would be c. £1.3bn, and unknown positive impact, there it is not required.
