Is the Free Boiler Scheme Real?
Yes, absolutely. The free boiler replacement scheme is part of the Energy Company Obligation (ECO4), a government-mandated programme that requires large energy suppliers to fund home energy improvements. It is regulated by Ofgem and has been running in various forms since 2013. In 2026, eligible households can receive a brand-new A-rated boiler at zero cost.
Fact: Energy companies are legally required to fund these boiler replacements. You pay nothing — not for the boiler, not for installation, not for any materials.
Who Qualifies for a Free Boiler?
To qualify for a free boiler replacement through ECO4, you need to meet two criteria:
1. You receive a qualifying benefit
- Universal Credit
- Pension Credit (Guarantee Credit)
- Income-based Jobseeker's Allowance (JSA)
- Income-related Employment and Support Allowance (ESA)
- Income Support
- Child Tax Credit (income under £16,480)
- Working Tax Credit (income under £16,480)
- Housing Benefit
2. Your home has a low EPC rating
Your property needs an Energy Performance Certificate rating of D, E, F, or G. Most older homes with inefficient boilers already qualify. Your installer can check your EPC rating for you.
3. Your existing boiler is old or inefficient
Your current boiler should be old (typically 15+ years), broken, or rated below 86% efficiency. Non-condensing boilers almost always qualify for replacement.
What Boiler Will You Get?
You'll receive a brand-new A-rated condensing boiler from a leading manufacturer. Common brands include:
- Worcester Bosch — 5-10 year warranty
- Vaillant — 5-7 year warranty
- Baxi — 7-10 year warranty
- Ideal — 5-12 year warranty
The type of boiler (combi, system, or regular) depends on your property size, number of bathrooms, and existing pipework. Your surveyor will recommend the best option.
How Much Will You Save?
| Current Boiler | Estimated Annual Saving |
|---|---|
| G-rated (old, pre-2005) | Up to £580/year |
| F-rated | Up to £490/year |
| E-rated | Up to £370/year |
| D-rated | Up to £230/year |

What About Heat Pumps?
ECO4 also funds air source heat pumps as an alternative to boiler replacement. Heat pumps are more energy efficient and produce lower carbon emissions. However, they require more space and are not suitable for every property. Your surveyor will advise whether a heat pump or boiler is the better option for your home.
