Energy Performance Certificates: Batteries
- Question
-
To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the potential merits of enabling stand alone batteries (without solar PV) to contribute towards a properties EPC rating.
- Answer
-
In the Home Energy Model (HEM): Energy Performance Certificate (EPC) consultation, we proposed how technologies including batteries could contribute to future EPC ratings.
The introduction of HEM will enable a half hour resolution that can more accurately estimate the impact of batteries on a home’s energy performance.
We are currently reviewing the consultation responses, including on the weighting of the different technologies in the EPC metrics. We will publish a Government Response by the end of the year.
