An Energy Performance Certificate is required for all domestic properties on completion, sold or let. The Energy Performance Certificate provides details on the energy performance of the property.

All non-domestic buildings on construction, sale and rent require a Non-Domestic Energy Performance Certificate (NDEPC) and a Recommendation Report (RR).

This information helps owners and occupiers make their house or building more energy efficient and allow potential buyers or tenants to compare the energy performance of different buildings.

All larger public buildings require an annual Display Energy Certificate (DEC) highlighting their energy performance.
