In 2015, 26% of homes in Great Britain were rated A to C for energy efficiency. By 2025, that figure had reached 56%, more than doubling in a decade. That matters because buyers and tenants are looking beyond the asking price or monthly rent. They also want to understand what a property could cost to run.
For homeowners, improving energy efficiency can make a home more comfortable and help reduce energy use. When selling, a stronger rating can also give buyers something positive to consider alongside location, space and condition. For landlords, it is about the quality and long-term appeal of the property. A home that retains heat effectively can be more attractive to tenants concerned about household bills.
However, an EPC rating is a guide, rather than a promise of running costs. Actual bills depend on the property, its heating system and how the occupants use it. Start by reading your EPC recommendations. Consider which improvements suit your property and budget, rather than assuming the most expensive option should come first.
Whether you are selling, letting or staying put, understanding your home’s energy performance is a useful starting point.
