What is an Energy Performance Certificate?

An Energy Performance Certificate (EPC) is a legally required document that provides a detailed overview of a property's energy efficiency. It gives the property an energy efficiency rating from A (most efficient) to G (least efficient) and is valid for 10 years. An important question many people ask is "do I need a new EPC to sell my house?" - yes, a valid EPC is required for sale or rent.

The certificate includes information on the property's energy use, carbon dioxide emissions, and a recommendation report with suggestions on how to improve the property's energy efficiency. This helps homeowners, landlords, and potential buyers or tenants understand the energy running costs of a property and how they can be reduced. For sellers, understanding the benefits of a high EPC rating for sellers is key, as it can influence property value, especially with the rise of green mortgage EPC requirements.

Example of an Energy Performance Certificate
When is an EPC Required?
  • Selling a Property: You must order an EPC for potential buyers before you market your property to sell.
  • Renting a Property: Landlords need to provide tenants with a valid EPC. Since 2018, rental properties must have a minimum EPC rating of 'E' (unless exempt), a key part of landlord MEES requirements.
  • Newly Built Properties: All new build homes require a SAP EPC before they can be sold or rented out.

The EPC Report Explained

The EPC report has two main parts. First, the energy efficiency rating, which is a visual A-G scale showing the current and potential rating of the property. A higher rating means lower energy bills. How long does an EPC take? The assessment is quick, usually under an hour for a standard home.

Second, the recommendation report. This section provides a list of cost-effective measures to improve the building's energy rating. If you need to know how to improve EPC rating from E to C, this report is your guide. Recommendations can include:

  • Loft insulation
  • Cavity or solid wall insulation
  • Upgrading to double or triple glazing
  • Installing a more efficient boiler
  • Switching to low-energy lighting
  • Installing renewable energy technology like solar panels
