Energy grants in the UK
Energy grants in the UK help households make their homes warmer, more efficient and cheaper to run. This hub explains the main routes and helps you check which support may be worth checking for your home.
What energy grants may be available?
Common UK schemes include ECO4, the Great British Insulation Scheme, the Boiler Upgrade Scheme, Warm Homes funding and local authority programmes. Each one targets different households, property types and improvements.
Who may qualify?
- Homeowners and tenants with EPC ratings of D-G
- Households on a lower income or receiving qualifying benefits
- Households with a vulnerable, elderly or disabled occupant
- Landlords looking to upgrade rental properties under qualifying routes
Why EPC rating matters
Most major schemes prioritise less efficient homes. EPC D-G properties are usually targeted first because the impact of insulation and heating upgrades is highest there.
Grants for insulation
Loft, cavity wall and solid wall insulation may be partly or fully funded under ECO4 or the Great British Insulation Scheme. Eligibility is confirmed by an approved installer and your local authority can refer households under flexible eligibility.
Grants for heat pumps
In England and Wales, the Boiler Upgrade Scheme may offer support towards installing an air or ground source heat pump. Scotland has its own routes via Home Energy Scotland.
Solar and battery support
Direct solar grants are limited but VAT relief on installation and some local authority schemes may help. Watch out for misleading "free solar" advertising.
Local council energy grants
Many councils run their own funding windows or refer residents into national schemes. Always confirm current availability with your local authority before acting.

Frequently asked questions
Are UK energy grants guaranteed?
No. All schemes have eligibility criteria and final approval depends on the scheme provider, local authority, installer assessment and property survey.
Do I need to be on benefits?
Not always. Many schemes also accept lower-income households or those with vulnerable occupants under local authority flexible eligibility.
Can I apply directly?
Most schemes are delivered via approved installers or local authorities. You can use the free energy grant checker to see possible routes before applying.
How long do energy grant applications take?
Timeframes vary. A property survey, paperwork checks and installer scheduling can take a few weeks to several months depending on the scheme and demand in your area.
Do I have to pay anything?
Some measures are fully funded for eligible households. Others, particularly solid wall insulation and some heat pump installs, may require a household contribution.
Can I combine multiple schemes?
Sometimes. For example, ECO4 may fund insulation while the Boiler Upgrade Scheme contributes to a heat pump. An installer or retrofit coordinator can advise on combinations.
