To ask the Secretary of State for Levelling Up, Housing and Communities, with reference to the Written Statement of 24 October 2023 on Building Safety Update, UIN HCWS1090, what assessment his Department has made of the potential impact of changes to Approved Document B on second staircase design on the delivery of new homes.

The Written Statement confirms the government’s intended transitional arrangements as we make a gradual evolution of safety standards in the built environment. These arrangements will ensure there is minimal impact on housing supply; should help secure the viability of projects that are already underway and avoid delays.  They have been designed with engagement from the construction industry and other stakeholders. Policy implementation will continue to follow due process with design details and impact analysis published as soon as possible.
