Energy efficiency rating
Energy Performance of Buildings Certificates: glossary, originally published by the Ministry of Housing, Communities & Local Government in 2014, defines an Energy Efficiency Rating (EER) as: ‘… a measure of the overall efficiency of a building. This rating is based on the performance of the building and its fixed services (such as heating and lighting). The higher the rating the more energy efficient the home is and the lower the fuel bills will be. An EPC will show both the current energy and potential energy rating of a property in terms of its energy rating. The energy efficiency rating charts are divided into rating bands ranging from A+ to G, (or A to G in the case of a building that is a dwelling), where A+ is very efficient and G is the least efficient. Each chart has a current and a potential energy efficiency rating.
