An Energy Performance Certificate, otherwise known as an EPC, is a rating awarded to a property that provides the homeowner and potential tenant(s) with an indication of its energy efficiency. Ratings are alphabetical, with A indicating the strongest rating and G representing the lowest.
The higher a rating, the more energy efficient the property, thus meaning better overall output for energy generation and cost-efficient utility bills.
An EPC is a UK law and minimum requirement for landlords letting their property. The EPC needs to be in place before any tenant moves into the property. Certificates are valid for 10 years, and you can check if a property has a valid EPC by visiting the EPC Register.
Since April 2018 it is illegal to rent any residential or commercial property in England, Scotland or Wales with an EPC Rating below E.
