Energy Performance
Energy Performance Certificates (EPC) is required under the European Energy Performance of Buildings. In England and Wales they are being introduced as part of the Home Information Packs (HIPS). The potential positive impact of EPCs has been obscured by the controversy surrounding the introduction of HIPS. An EPC provides:
- an energy efficiency rating;
- an environmental impact rating; and
- an assessment of the potential for improvement -defined as all the measures that would be cost effective (i.e. paying back over seven years) such as insulation, together with further measures beyond the cost-effective potential, such as double glazing, photo-voltaics and solar thermal.
The ratings are expressed in Standard Assessment Procedure (SAP) points and presented in bands A-G, using the familiar EU Energy Label that is on many household appliances.
The progressive roll out of EPCs across different dwelling types means that by the end of 2008 a property can only be put up for sale when an EPC has been obtained.

EPC Forum
The EPC initiative is seen as central to driving up the demand for more energy efficient homes. Recent research by the EST has indicated the potential: two thirds of those surveyed stated that energy efficiency was an important consideration when buying a home and over 50% said they would pay an additional £10,000 for ‘an environmentally friendly' property.
