Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether his Department plans to take steps to update energy performance certificates to ensure they accurately reflect the actual energy performance of homes.

The Government is reviewing the building physics model and methodology underpinning EPCs to make it fit for purpose to support net zero. A public consultation on the new building physics model, the Home Energy Model, closed on 27 March 2024.

We are now reviewing the responses and will publish a response in the coming months. We will also consult shortly on proposals to improve EPCs and aim to consult further on the underlying Home Energy Model for producing them in 2025.
