An EPC, or Energy Performance Certificate, is a document that rates how energy-efficient a property is. The ratings range from A (most efficient) to G (least efficient). It's a legal requirement for a property owner to have an EPC when they are selling, renting, or building a property.

 

The EPC provides potential buyers or tenants with an indication of the property's energy efficiency, which can be a significant factor in their decision-making process, as it can influence future energy bills. In addition, the certificate includes recommendations on how to improve the property's energy efficiency, which can help owners reduce their carbon footprint and save money.
