Energy Performance Certificates

This page provides guidance on Energy Performance Certificates (EPC) in relation to historic buildings for those who need to obtain a certificate as well as those who carry out the assessment.

An EPC provides a rating so that comparisons on energy performance can be made between different properties. They are generated by a standard form of modelling software which does not always correspond to actual performance. Recent research has shown this can significantly underestimate thermal performance in older buildings.

As such ratings may lead to inappropriate recommendations which could harm the character or risk deterioration of such buildings, Historic England has developed guidance to raise awareness of the issues.

Legislation

An EPC is required when a building is built, sold or rented and is valid for ten years.
Listed buildings and buildings in conservation areas have a qualified exemption.
For more details see our page on Consents and Regulations for Energy Improvements to Older Homes.
