Housing: Construction

The question

To ask the Secretary of State for Housing, Communities and Local Government, with reference to Written Statement of 24 March 2026 on Future Homes and Building Standards, HCWS1445, whether the technical review of Approved Document O of the Building Regulations will tackle the potential risk of overheating in new and existing homes.

Answered by Samantha Dixon

Part O was introduced in 2021 to reduce the risk of overheating in new residential buildings. In the response to the Future Homes and Buildings Standards consultation, the Government committed to a full technical review of Part O to ensure it is effective and proportionate and consider whether changes to the standard are necessary.

The Building Regulations apply to new building work and, therefore, the potential risk of overheating in existing homes is outside of the scope of Part O.
