Housing: Heating
The question
To ask the Secretary of State for Housing, Communities and Local Government, what recent assessment she has made of the (a) quality and (b) efficiency of radiator systems installed in new-build homes.
Answered by Alex Norris
Statutory guidance on the design of radiator systems in new-build homes is set out in Approved Document L Volume 1, which accompanies Part L (Conservation of Fuel and Power) of the Building Regulations. This is intended to ensure that radiator systems in new homes are correctly sized, energy efficient, and equipped with appropriate controls.
The most recent update to this guidance was made through the 2021 uplift to Part L, which came into effect in June 2022. The Future Homes and Buildings Standards (FHBS) consultation, which closed in March 2024, proposed further changes to Part L and the accompanying Approved Documents to improve the energy efficiency of heating systems in new-build homes. The Government intends to publish its response to the FHBS consultation in autumn this year.
