What is an Energy Performance Certificate?
According to GOV.UK, an Energy Performance Certificate (EPC) is a legal document that rates your property's energy efficiency on a scale from A to G. It includes information about your home's energy use, typical energy costs, and recommendations for improving efficiency.
EPCs are required by law whenever a property is built, sold, or rented. They are produced by accredited energy assessors who survey the property's construction, insulation, heating systems, and other features.
The certificate also includes a score from 1 to 100, with higher scores indicating better energy efficiency. Band A properties score 92 or above, while band G properties score 1 to 20.
EPC Rating Bands: A to G
Band A (92-100)
Most energy efficient. Very low energy costs. Typically new-build homes with excellent insulation, solar panels, and heat pumps.
Band B (81-91)
Very energy efficient. Low energy bills. Well-insulated homes with modern heating systems and double/triple glazing.
Band C (69-80)
The government's target band for all UK homes. Reasonable energy costs. Properties with adequate insulation and efficient heating.
Band D (55-68)
According to the English Housing Survey, D is the most common rating in the UK. Moderate energy costs with scope for improvement.
Band E (39-54)
Below average efficiency. Higher energy costs. May qualify for ECO4 grants. Landlords must reach at least band E for rental properties.
Band F (21-38)
Poor energy efficiency. High energy bills. Strong candidate for ECO4 and Warm Homes Plan grants. Cannot be legally rented without exemption.
Band G (1-20)
Least energy efficient. Very high energy costs. Highest priority for government grant schemes. Significant improvement potential.

How Your EPC Rating Affects Grant Eligibility
ECO4 Scheme
According to Ofgem, ECO4 targets properties rated D, E, F, or G. Lower-rated properties receive higher priority for funding.
Boiler Upgrade Scheme
According to GOV.UK, the BUS has no EPC rating requirement. Any homeowner in England or Wales replacing fossil fuel heating can apply.
Warm Homes Plan
The Warm Homes Plan prioritises properties with poor energy efficiency. Lower EPC ratings typically qualify for more comprehensive packages.
