Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, if he will make an assessment of the potential merits of listing air-to-air heat pumps as a cost-effective way to improve a property’s energy performance certificate rating.

Energy Performance Certificates (EPCs) are a critical tool in informing consumers about the running costs of their homes, helping them reduce both energy bills and carbon emissions. The EPC model already recognises the performance of air-to-air heat pumps. The government is reviewing the building physics model and methodology underpinning EPCs to better support net zero goals, including deployment of heat pumps. Government will shortly set out a consultation with proposals for improvements to EPCs, including proposals for improving EPC metrics.
