It is two years since the introduction of Energy Performance Certificates (EPCs) as part of the information provided to people buying and selling homes in England and Wales.
EPCs contain information on the energy efficiency of the property, its likely fuel costs and carbon dioxide emissions, together with recommendations of possible improvement measures, the rating and the savings they could deliver.
The NHER scheme runs one of the largest accreditation schemes for Domestic Energy Assessors who are able to produce these EPCs.
