UK Energy Efficiency Grants 2026: What Homeowners Can Claim
Updated guide to government schemes for boilers, heat pumps, and insulation in 2026.
The UK government continues to offer substantial grants to help homeowners improve their home's energy efficiency. Here's what's available in 2026 and how to claim.
Boiler Upgrade Scheme (BUS)
The Boiler Upgrade Scheme remains the flagship grant for heat pump installations:
- Air source heat pumps: Up to £7,500 grant
- Ground source heat pumps: Up to £7,500 grant
- Biomass boilers: Up to £5,000 grant (rural properties only)
To qualify, your property must have an EPC (no minimum rating required since April 2025) and you must use an MCS-certified installer.
ECO4 Scheme
The Energy Company Obligation (ECO4) provides free or heavily subsidised improvements for low-income households:
- Boiler replacements
- Loft and cavity wall insulation
- Smart heating controls
- First-time central heating
Eligibility typically requires receiving benefits such as Universal Credit, Pension Credit, or Child Tax Credit.
Great British Insulation Scheme
This scheme helps middle-income households in the least energy-efficient homes:
- Properties in Council Tax bands A-D (England) or A-E (Scotland/Wales)
- EPC rating D, E, F, or G
- Free or low-cost cavity wall and loft insulation
Local Authority Grants
Many councils offer additional grants. Check your local authority website for:
- Home improvement loans
- Disabled facilities grants
- Green homes initiatives
How Cover Plans Complement Grants
While grants help with installation costs, they don't cover ongoing maintenance or breakdowns. A CareClub plan ensures your new heat pump or boiler stays protected:
- Annual servicing included
- 24/7 emergency breakdown cover
- No excess on callouts
- Parts and labour covered
How to Apply
- Check your EPC at gov.uk/find-energy-certificate
- Use the Simple Energy Advice service to find available grants
- Get quotes from certified installers
- Apply through the installer (for BUS) or energy supplier (for ECO4)
