Written question asked by Carla Denyer (Green Party) on Monday, 18 May 2026, in the House of Commons. It was due for an answer on Wednesday, 20 May 2026. It was answered by Samantha Dixon (Labour) on Friday, 22 May 2026 on behalf of the Ministry of Housing, Communities and Local Government.


Housing: Construction

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.

Answer

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.
