A recent Home Sale Network survey indicates that Energy Performance Certificates (EPCs) have little impact currently on the sale and purchase of property.  Home buyers do not consider a property's rating to be a key part of their purchase criteria nor a lever to negotiate a purchase price or rent.

Introduced as part of Home Information Packs (HIPs) in August 2007, EPCs provide infromation on reducing a building's carbon dioxide emissions and consequently making them more energy efficient.  The certificates carry rating measures with 'A' being the most efficient and 'G' being the least and with all homes bought, sold or rented now requiring an EPC, energy efficiency has become more important than ever.
