An Energy Performance Certificate must be made available to a prospective purchaser providing details of the energy performance of the property, along with any recommendations for improvement.
The EPC provides a rating of the properties energy efficiency and displays this as a graph, similar to those found on kitchen appliances. It doesn’t look at the appliances, but rather the performance of the building itself in areas such as heating and lighting.
Ratings come on a scale of A-G, with A being the best rating. Most homes in the UK have a band D-E rating for both the Energy Efficiency and Environmental Impact.
Energy Performance Certificates (EPCs) give information on how to make your home more energy efficient and reduce carbon dioxide emissions. All homes bought, sold or rented require an EPC.

EPCs are valid for ten years, except if they are part of a Home Information Pack (HIP). If it is part of a HIP, an EPC must be less than three years old when the building is first put on the market.
