The question

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the potential impact of the introduction of RdSAP 10 on the unit cost of an Energy Performance Certificate.

Answered by Miatta Fahnbulleh

The Introduction of RdSAP 10 improves the accuracy of Energy Performance Certificate (EPC) assessments, helping households better understand their energy use. The fees charged are not set by government and reflect the commercial decisions of individual assessors or their employers.

RdSAP 10 delivers more accurate assessments and clearer recommendations for property owners. This supports better outcomes for consumers and enhances the credibility of EPCs.
