Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether he will make an assessment of the potential merits of amending the requirement to use an existing Energy Performance Certificate (EPC) rating to determine eligibility for insulation funding where that EPC was produced prior to the subsequent installation of a heat pumps or solar panels.

Support is available for households to install insulation, alongside measures such as heat pumps and solar PV, through the Warm Homes: Local Grant (WH:LG) and the Warm Homes: Social Housing Fund (WH:SHF). These schemes take a whole‑house approach, with assessments carried out by qualified professionals to determine the most appropriate improvements for each property.

Where Grant Recipients of the WH:LG expect that the energy performance of a home has changed since the most recent Energy Performance Certificate (EPC) was produced, they should ensure a new EPC is created to properly assess eligibility.

Government is reforming EPCs to provide a clearer and more accurate picture of a building’s performance, including through the introduction of metrics covering fabric, heating systems, smart readiness and energy costs.

We will launch EPC reforms in the second half of 2027.
