Understanding EPC Ratings
What do EPC ratings mean for property value? Learn how Energy Performance Certificates affect house prices and running costs.
What Is an EPC?
An Energy Performance Certificate rates a property’s energy efficiency from A (most efficient) to G (least efficient). Since 2008, an EPC has been required for all property sales and lettings.
How EPCs Affect Price
Research shows that a one-letter EPC improvement can add 1-5% to a property’s value. Buyers increasingly factor in running costs.
What Drives EPC Scores
Wall and loft insulation, boiler type and age, window glazing, heating controls, and renewable energy sources all feed into the score.

Look for double glazing, solar panels, modern boilers, and loft hatches that suggest insulation. These clues help estimate both the EPC band and the likely price impact.
