Energy grants for EPC D, E, F and G homes
Quick answer
Homes with an EPC rating of D, E, F or G are typically prioritised for UK energy grants because they have the most to gain from insulation and heating upgrades.
Why lower EPC homes are often targeted
Funding is directed where the impact on bills, comfort and emissions is greatest. Less efficient homes therefore qualify more easily for measures such as insulation and heating upgrades.
What EPC ratings mean
- A and B — highly efficient
- C — good
- D — average
- E and F — below average
- G — least efficient
Common improvements for D-G homes
- Loft insulation top-up
- Cavity wall or solid wall insulation
- Heating controls and modern boiler or heat pump
- Draught proofing
- Solar PV in some schemes
