What are boiler grants?
Boiler grants are government-backed or energy supplier-funded programmes that may help eligible UK households replace an old, broken, or inefficient boiler at no cost or reduced cost. The primary route for boiler replacement funding in 2026 is through the ECO4 scheme (Energy Company Obligation 4).
These grants aim to reduce fuel poverty and improve home energy efficiency. They are targeted at low-income and vulnerable households whose homes are poorly insulated or heated, and where replacing the boiler would make a meaningful difference to energy performance.
Can I get a free boiler?
The term “free boiler” is commonly used but can be misleading. There is no universal “free boiler for everyone” scheme. However, qualifying households may receive a fully-funded boiler replacement through ECO4 or local authority programmes without paying anything themselves.
To be considered, you typically need to meet specific eligibility criteria including receiving qualifying benefits, having a poor EPC rating, and having a boiler that is broken or inefficient. An approved installer assesses your property and confirms whether funding applies.
ECO4 boiler replacement schemes
ECO4 requires large energy suppliers to fund energy efficiency measures for eligible households. Boiler replacement is one of the most common measures delivered under ECO4, particularly for homes with broken or G-rated boilers.
Under ECO4, a boiler replacement is usually part of a wider package of improvements designed to raise your home’s EPC rating by at least two bands. This may include insulation measures alongside the new boiler.
ECO4 runs until March 2026, with a successor scheme expected. Eligibility criteria may change between programme phases, so checking your current eligibility is always worthwhile.
Who may qualify?
You could be eligible for a boiler grant if you meet one or more of the following criteria:
- You receive qualifying benefits (Universal Credit, Pension Credit, Income Support, ESA, JSA, Child Tax Credit, or others)
- You meet local authority flexible eligibility (LA Flex) criteria
- Your property has an EPC rating of D, E, F, or G
- Your existing boiler is broken, condemned, or highly inefficient
- You are a homeowner or private tenant (with landlord consent)
- Your property is connected to mains gas (for gas boiler replacement)
Meeting these criteria does not guarantee qualification. Final eligibility is determined by the scheme provider and a certified installer following property assessment.
Boiler grants for pensioners
Pensioners are among the groups most commonly eligible for boiler grants. If you receive Pension Credit, you automatically meet the benefits criteria for ECO4. Even without Pension Credit, some local authority schemes specifically target older residents who may be vulnerable to cold-related health issues.
If you are over state pension age and struggling with heating costs, it is worth checking eligibility regardless of your exact benefit situation — local authority flex criteria may apply based on age, health, or income.
Boiler grants for homeowners
Homeowners who meet the eligibility criteria can apply for ECO4-funded boiler replacements. You own the property and are responsible for your own heating, making you eligible to have measures installed with your consent.
There is no requirement to have a mortgage or be mortgage-free. What matters is your EPC rating, benefits status, and whether your boiler needs replacing for energy efficiency reasons.
Boiler grants for people receiving benefits
Receiving certain means-tested benefits is one of the primary qualification routes for ECO4. Qualifying benefits typically include:
- Universal Credit
- Pension Credit
- Income Support
- Income-based JSA
- Income-related ESA
- Child Tax Credit
- Working Tax Credit
- Housing Benefit
If you receive any of these benefits and have an inefficient heating system, you may be eligible for support. Use the checker above to find out which schemes could apply to your situation.
Alternatives to boiler grants
If you do not qualify for a fully-funded boiler replacement, other options may still help reduce your heating costs:
- Boiler Upgrade Scheme — provides up to £7,500 towards a heat pump installation, replacing your boiler with a more efficient renewable system.
- Insulation grants — improving insulation can reduce heating demand, meaning your existing boiler works less hard and your bills decrease.
- Boiler finance — some installers offer 0% finance or payment plans for new boiler installations, spreading the cost over several years.
- Energy supplier discounts — contact your energy supplier directly, as some offer discretionary boiler repair or replacement support.
Common Myths About Boiler Grants
“Everyone qualifies for a free boiler”
Eligibility is based on specific criteria including benefits, EPC rating, and property type. Not all applications are approved.
“Grants cover every property and boiler type”
Some properties may not qualify due to EPC rating, location, or existing heating efficiency. Each scheme has its own scope.
“All you need is a broken boiler”
A broken or inefficient boiler alone does not guarantee eligibility. Other factors including household income, benefits, and property efficiency are assessed.
“No assessment is needed”
An approved installer must assess your property before work begins. This confirms eligibility, measures required, and whether the scheme applies to your home.

Frequently asked questions
Can I get a free boiler from the government?
There is no single "free boiler" scheme open to all households. However, ECO4 and some local authority programmes may fund boiler replacements for eligible low-income or vulnerable households. Whether you qualify depends on your benefits, property EPC rating, and other criteria set by the scheme provider.
Who qualifies for boiler grants?
Eligibility varies by scheme. ECO4 typically requires receiving qualifying benefits (such as Universal Credit, Pension Credit, or Income Support) or meeting local authority flexible eligibility criteria. Your property usually needs an EPC rating of D, E, F, or G with a broken or inefficient boiler. Final qualification is confirmed by a certified installer.
Can pensioners get boiler grants?
Pensioners receiving Pension Credit or other qualifying benefits may be eligible for ECO4-funded boiler replacements. Some local authority schemes also prioritise older or vulnerable residents. Each programme has its own criteria, so it is worth checking even if you are not certain you qualify.
Do I need to receive benefits?
For ECO4, receiving qualifying benefits is one of the main eligibility routes. However, local authority flexible eligibility (LA Flex) criteria may also apply based on income, health conditions, or fuel poverty indicators. Some households qualify without receiving means-tested benefits.
