Question to the Ministry of Housing, Communities and Local Government:

To ask the Secretary of State for Housing, Communities and Local Government, what steps she plans to take to ensure that the revised Approved Document B includes an evidence-based route for demonstrating compliance for building-integrated green infrastructure, including living walls and green roofs, through whole-system fire performance assessment where appropriate.

The Government consulted on proposed changes to Approved Document B and no final decisions have been taken. The Building Safety Regulator is currently analysing consultation responses and supporting evidence, including views relating to living walls, green roofs and other forms of green infrastructure on non-residential buildings of all heights. The Government will consider the advice of the Building Safety Regulator and the evidence received through the consultation before making any decisions on changes to the guidance, including consideration of evidence relating to approaches for demonstrating compliance with the Building Regulations. The Government has no plans to update the impact assessment for the proposed changes to Approved Document B.
