Energy Efficiency and Historic Buildings: Energy Performance Certificates

Buy printed version from bookshop

This guidance is aimed at homeowners and those managing or renting historic or older domestic buildings who may need to commission an Energy Performance Certificate (EPC) or who have received one for an older property that has been purchased or rented.

Details are provided on the type of information included in an EPC, how it is calculated, and its limitations as an assessment method when applied to older buildings. The guidance also covers the issues to be taken into account when commissioning an EPC and considering its recommendations.

Almost every older building can accommodate some energy improvements without harming either its special interest or environmental performance. However, an appropriate balance needs to be achieved between building conservation and measures to improve energy efficiency if lasting damage is to be avoided both to a building’s character and significance and its fabric.


Changes to the Green Deal

Since this guidance was published, the Green Deal referred to on page 9 has been revised. For the latest information on the Green Deal please refer to the Government web page ‘ Green Deal: energy saving for your home’. The page provides an overview of the scheme, improvements and benefits to your home, getting an assessment, getting the work done and how to pay.

Forthcoming changes to Energy Performance Certificates

In 2018, the Government ran a call for evidence on how Energy Performance Certificates (EPC) currently perform against three attributes: quality, availability and encouraging action to improve energy efficiency. Find out more about the proposed revisions to the EPC system.
