Did you know your home’s Energy Performance Certificate (EPC) rating can reveal why your energy bills are higher than expected and highlight ways to improve your property’s energy efficiency?

Whether you’re a homeowner, landlord, buyer or tenant, checking your EPC rating is one of the quickest ways to understand how energy-efficient a property is and what improvements could help reduce energy consumption.

In this guide, we’ll explain how to check your EPC rating, what the different EPC bands mean, and how energy-efficiency improvements such as insulation, solar panels, battery storage and heat pumps can help improve your home’s performance.

What Is an EPC Rating?

An Energy Performance Certificate (EPC) measures the energy efficiency of a property on a scale from A to G.

  • A = Most energy efficient
  • G = Least energy efficient

An EPC includes:

  • An overall energy-efficiency score
  • Estimated energy costs
  • Environmental impact information
  • Recommendations for improving efficiency
  • Potential future EPC rating after improvements

A better EPC rating can often mean lower running costs, improved comfort and a more attractive property for future buyers or tenants.
