Energy grants for EPC D, E, F and G homes

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.

ECO4 and insulation

ECO4 and the Great British Insulation Scheme are the main UK routes for free or part-funded insulation and heating upgrades.

Do I qualify for ECO4?

You may qualify for ECO4 if your household receives qualifying benefits, is on a low income, or includes a vulnerable occupant, and your home has an EPC rating of D-G. Final eligibility is confirmed by an approved installer.

Great British Insulation Scheme (Closed)

The Great British Insulation Scheme (GBIS) closed to new applications on 31 March 2026. Existing applications submitted before the deadline may still be processed. For insulation support, check ECO4 or Warm Homes routes instead.

Can I get free insulation?

You may be able to get free or part-funded insulation through ECO4 or Warm Homes funding if your home has an EPC rating of D-G and your household is on a lower income, receives qualifying benefits, or includes a vulnerable occupant. The Great British Insulation Scheme closed to new applications on 31 March 2026.

Insulation grants in the UK

Insulation grants in the UK are mainly available through ECO4 and local authority Warm Homes routes. The Great British Insulation Scheme closed to new applications on 31 March 2026. Most schemes prioritise EPC D-G homes and lower-income or vulnerable households.

Loft insulation grants

You may qualify for free or part-funded loft insulation through ECO4 or Warm Homes funding if your home has a low EPC rating and your household meets common low-income or vulnerability criteria. The Great British Insulation Scheme closed to new applications on 31 March 2026.

Cavity wall insulation grants

You may qualify for free or part-funded cavity wall insulation if your home has a suitable unfilled cavity, an EPC rating of D-G, and your household meets common income, benefits or vulnerability criteria.

Solid wall insulation grants

Solid wall insulation can be funded under ECO4 and Warm Homes funding for eligible homes. Higher grant amounts often apply because the cost is higher than other insulation types.

EPC and home efficiency

Most major schemes prioritise EPC D-G homes. These guides explain how to look up, improve and use your EPC band.

EPC improvement grants

Several UK schemes can help you fund the measures recommended on your EPC. Insulation and heating upgrades typically deliver the biggest jumps in rating.

Solar and batteries

Solar panel routes for UK homes, including the Smart Export Guarantee, 0% VAT and any local authority schemes.

Solar panel grants in the UK

There is no single national solar panel grant in the UK. Several routes can reduce cost: local authority schemes, ECO4 in specific cases, 0% VAT on installs and Smart Export Guarantee payments.

Free solar panels in the UK

Truly free solar panel offers in the UK are limited. Some local authority schemes, ECO4 routes and group-buy programmes can substantially reduce or remove the cost for eligible households.

Heat pumps

How the Boiler Upgrade Scheme works for air source and ground source heat pumps in eligible properties.

Heat pump grant amounts

In England and Wales, the Boiler Upgrade Scheme provides grants towards air source and ground source heat pumps. Amounts are set by Government and may change. Scotland has its own grant and interest-free loan.

Boiler upgrade grant

The Boiler Upgrade Scheme is a UK Government grant towards installing low-carbon heating such as air source and ground source heat pumps in England and Wales.

Landlords and tenants

How rented homes can access UK energy grants, including who can apply and what consent is needed.

Energy grants for landlords

Landlords may be eligible for several UK energy grants to improve rental properties, particularly under ECO4, the Boiler Upgrade Scheme and local authority schemes. Tenant eligibility and EPC rules apply.

Energy grants for tenants

Tenants may qualify for UK energy grants in their rented home, often with the landlord’s permission. Eligibility usually depends on income, benefits, vulnerability and the property’s EPC rating.

Energy grants for pensioners

Pensioners may be prioritised for UK energy grants where they receive Pension Credit, are on a lower income, or live in a cold home that affects health. Age alone does not guarantee eligibility, but combined with these factors it often improves the case.

Local and regional grants

Country-specific schemes for England, Wales, Scotland and Northern Ireland alongside national UK routes.

Warm Homes Local Grant

Warm Homes: Local Grant funds insulation, heating and ventilation upgrades through local authorities, prioritising lower-income households and homes with low EPC ratings.

Energy grants in England

Energy grants in Scotland

In Northern Ireland, current support routes include the Affordable Warmth Scheme and the Northern Ireland Sustainable Energy Programme (NISEP) 2026/27. The Boiler Replacement Scheme is closed. ECO4, the Boiler Upgrade Scheme and the Smart Export Guarantee do not operate in Northern Ireland.
