Eco Boiler Grant Scheme: Who Qualifies and How to Apply with Eco Renewables
The Eco Boiler Grant Scheme, part of the government-backed ECO4 programme, offers free or heavily subsidised boiler replacements to eligible UK households. To qualify, your property must be owner-occupied or privately rented with landlord consent, have an EPC rating of D or below, and either receive specific means-tested benefits or meet low-income and cold‑household criteria through Local Authority Flex. Eco Renewables helps you check eligibility using our application process via our Do I Qualify for ECO4 funding?.
What Is the ECO Boiler Grant Scheme?
The ECO Boiler Grant Scheme is delivered under the Energy Company Obligation 4 (ECO4), active from April 2022 until March 2026, funded by major energy suppliers. Its aim is to support vulnerable and low-income households in England, Scotland and Wales by replacing inefficient, aging boilers with modern, energy-efficient models to reduce fuel costs and carbon emissions.
Successful applicants can receive up to a full boiler replacement at no upfront cost if they meet eligibility criteria. Partial funding may also be available in some cases.

FAQs about Eco Boiler Grant Scheme
Can tenants qualify for the grant?
Yes, private tenants are eligible with written landlord consent and meeting benefit or income criteria. We assist you throughout this process.
What if my boiler is only five years old?
It may still qualify as faulty or inefficient, especially if non-condensing. The installer will assess during the survey.
Do I need to pay anything upfront?
Typically, no. If fully funded you pay nothing. Some cases require a minimal household contribution depending on scheme limits.
Can I still apply if I already had insulation grants?
Yes, boiler grants require no outstanding insulation recommendations. Prior insulation funding doesn’t disqualify you.
When does the scheme end?
ECO4 runs until 31 March 2026. After that, the new Warm Homes mandate will begin but funding remains limited.
