Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what discussions his Department has had with the Scottish government on (a) reforms to Energy Performance Certificates and (b) how Energy Performance Certificates measure the performance of traditionally constructed buildings.

Ministers engage regularly with Scottish Government counterparts across a range of policy areas, including through the Net Zero, Energy and Climate Change Interministerial Group (IMG). Departmental officials meet Scottish Government counterparts regularly, most recently in February 2025, on matters including Energy Performance Certificate (EPC) reforms. HM Government and Scottish Government will make independent decisions on what the EPC will measure but it is intended that both will use a common calculation framework, the Home Energy Model (HEM). It will support options for building types that are especially prevalent in Scotland including for traditional dwellings.
