An Energy Performance Certificate (EPC) is a document that provides information about the energy efficiency of a building. It is typically required when a building is constructed, sold, or rented. The EPC gives a rating of the building's energy efficiency on a scale from A (most efficient) to G (least efficient), and includes recommendations for ways to improve the building's energy efficiency. Having an EPC can help a building owner or tenant to reduce their energy costs and to make the building more environmentally friendly. It is mandatory to have an EPC to sell or rent out a property in many countries.
