Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what his planned timetable is to (a) reform the EPC system and (b) introduce a new Home Energy Model in 2026.

The government is working to reform EPCs so that they support our key objectives of achieving Clean Power by 2030 and accelerating to Net Zero. The government expects to introduce changes to EPCs metrics in 2026.

The Home Energy Model (HEM) will replace the current Standard Assessment Procedure (SAP) as the methodology underpinning EPCs and building regulations, and is planned to be implemented first alongside the Future Homes Standard.
