This guidance provides advice to Domestic Energy Assessors (DEAs) and Green Deal Advisor’s (GDAs) producing Energy Performance Certificates and Green Deal Assessments on historic and older buildings.

Whilst many of the recommendations in Energy Performance Certificates and Green Deal Assessments will be suitable for older buildings some measures may need more careful consideration and specialist advice before works are put in hand.
For historic buildings and those of traditional construction 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.
