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

To ask the Secretary of State for Housing, Communities and Local Government, what assessment she has made of the effectiveness of Approved Document O of the Building Regulations in preventing overheating in newly constructed residential properties; and whether she plans to review the regulations to help mitigate excessive indoor temperatures and the associated impact on residents' health and energy costs.

I refer the hon. Member to the answer given to Question 29185 on 23 September 2026. The Government committed to undertaking a full technical review of Part O of the Building Regulations in its response to the Future Homes and Buildings Standards consultation. This review, which is being led by the Building Safety Regulator, is now underway.
