Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the potential impact of the installation of solar panels on the level of Energy Performance Certificate ratings for domestic properties.

Alongside lower electricity bills, there are many potential benefits for householders that invest in rooftop solar. These include improved property valuation and EPC scores, although the overall score for an individual property is based on several different variables.

Government has also consulted on introducing four complementary headline metrics for domestic EPCs: "Fabric Performance," "Heating System," "Smart Readiness," and "Energy Cost." The consultation proposed that the Smart Readiness metric would include information on a households’ ability to generate on-site renewable energy, including solar PV, and give specific recommendations for improvements to scores against the metric. Government will respond to this consultation in due course.
