Free Boiler Scheme UK: Check If You Qualify (ECO4)
Yes — for eligible homes. The UK free boiler scheme people search for is usually the Energy Company Obligation (ECO4) or council LA Flex pathway: a fully funded or free boiler replacement when you meet the rules — not a national voucher for every address. Check ECO4 eligibility first, or LA Flex if you are not on benefits.

What is the free boiler scheme in the UK?
When people say free boiler scheme, they usually mean government-backed energy-efficiency programmes where obligated energy suppliers (or approved installers working under those rules) fund heating upgrades for qualifying homes.
- ECO4 is the main national obligation route many households use for a free or fully funded boiler when benefits, income, or housing criteria are met.
- LA Flex lets councils nominate people who may not claim benefits but still meet local fuel-poverty or vulnerability criteria.
- Related policy context sits under the wider Warm Homes plan — that page covers the broader framework; this homepage is for free boiler scheme / ECO4-style boiler intent.
There is no universal entitlement. Funding and eligibility both have to line up.

Am I eligible for a free boiler?
At a high level, successful ECO4-style applications often involve one or more of:
- Qualifying benefits or low income
- A poorer EPC (often mid-to-low bands — exact thresholds depend on tenure and package)
- Private ownership or private rental (social housing routes differ)
Exact checks belong on the eligibility pillar — not guessed from social media “everyone qualifies” posts.
Check ECO4 eligibilityNo benefits? LA Flex may still help
If you are searching change boiler for free or how to get a free boiler but you are not on benefits, your council's LA Flex statement of intent may still open a route via income caps, health vulnerability, or similar local criteria.
LA Flex schemeHow the free boiler scheme works
- Check eligibility — Start with ECO4 or LA Flex.
- Survey — Eligible homes usually get a survey before measures are agreed.
- Install — Agreed heating work is installed under the scheme rules when funding is available.
How long a free boiler replacement takes varies by survey outcome, installer capacity, and scheme funding. We do not publish a fixed day-count here because there is no single verified SLA that fits every UK home.
