Can You Get a Free Boiler in 2026?
Yes — if you qualify for the ECO4 scheme. Under the Energy Company Obligation, large energy suppliers fund free boiler replacements for eligible households. This includes replacing broken, inefficient, or condemned boilers with modern A-rated condensing boilers at zero cost to you.
An old G-rated boiler wastes up to 40% of the energy it uses. Replacing it with a modern A-rated boiler typically saves £300-400 per year on gas bills. If your boiler is over 10 years old and you're on qualifying benefits, you could get a brand new one installed for free.
ECO4 Boiler Replacement: What's Covered
- New A-rated condensing gas boiler — fully installed with all controls
- First-time central heating — if you currently use electric heaters, this can save £900+/year
- Radiator upgrades — where needed as part of the heating system
- Smart thermostat — included with most installations
- All labour and materials — no hidden costs
Who Qualifies for a Free Boiler?
To qualify under ECO4, you need to meet ALL of these criteria:
- Receive a qualifying benefit: Universal Credit, Pension Credit, Income-based JSA, Income-related ESA, Income Support, Housing Benefit, Child Tax Credit, Working Tax Credit, or Warm Home Discount
- Own your property (or be a private tenant with landlord consent)
- Have an EPC rating of D, E, F, or G
- Have a broken, condemned, or inefficient existing boiler (typically 10+ years old)
Important: ECO4 focuses on "worst first" — homes with the lowest EPC ratings get priority. If your home is rated E, F, or G, you're in a strong position.
What About the Boiler Upgrade Scheme?
Don't confuse ECO4 boiler replacement with the Boiler Upgrade Scheme (BUS). BUS provides £7,500 towards a heat pump — not a gas boiler replacement. It's a different scheme with different eligibility criteria and doesn't require you to be on benefits.
