EPC Rating Chart - UK Home Energy Efficiency for Free Boiler Grants
What is an EPC Rating?
An Energy Performance Certificate (EPC) is a legal document that rates the energy efficiency of a property in the UK, using a scale from A (most efficient) to G (least efficient). The higher your EPC rating, the lower your energy bills and carbon footprint. EPCs are required when selling, renting, or applying for government energy grants.
Why Does Your EPC Rating Matter?
- Homes with a low EPC rating (D or below) may qualify for free boiler grants and insulation funding under the ECO4 scheme.
- Improving your EPC can increase property value and make your home more attractive to buyers or tenants.
- Better EPC ratings mean lower energy bills and a reduced environmental impact.
How to Improve Your EPC Rating
- Upgrade to an A-rated condensing boiler (often free via ECO4 grants)
- Add or improve loft and cavity wall insulation
- Install smart heating controls and thermostats
- Switch to energy-efficient lighting and appliances
- Consider renewable energy options like solar panels
Tip: If your EPC rating is D, E, F, or G, you are likely eligible for a free boiler grant or other energy-saving upgrades. Check your eligibility and start saving on your energy bills today!
