Warm Homes, Lower Bills: Your 2025 Guide to Free Boiler Grants
With UK energy bills soaring by 83% since 2021 and winter approaching, a faulty boiler isn’t just inconvenient—it’s a financial emergency. Over 2.4 million UK households live in fuel poverty, shivering through breakdowns because replacement costs feel impossible. What most don’t realise? You might qualify for a £0 boiler replacement RIGHT NOW. Government schemes like ECO4 and the Boiler Upgrade Scheme have allocated £4 billion to rip out old boilers and install new A-rated systems—no upfront cost if you meet the criteria 711.
This isn’t generic aid. This guide reveals the exact 2025 rules, loopholes, and application hacks based on 1,200+ successful installations we’ve managed at Ecomax Insulation.
The 3 Major Free Boiler Schemes (And Who Qualifies)
Free Boiler Grants enable eligible UK households to replace inefficient boilers at little or no cost.
Not all grants work the same. Choose the RIGHT one for your home:
1. ECO4 Scheme: The #1 Route for Low-Income Households
- Run time: Until March 2026
- Funding: Covers 100% boiler replacement costs (plus insulation/heat pumps)
- Eligibility Triggers:
- You receive Universal Credit, Pension Credit, Child Tax Credits, or other means-tested benefits.
- Your boiler is over 8 years old (or faulty)
- Your home’s EPC rating is D or below.
- Household income under £31,000? You may qualify via ECO4 Flex even without benefits.
2. Boiler Upgrade Scheme (BUS): £7,500 for Heat Pumps
- Run time: Until December 2027
- Funding: £7,500 for air/ground source heat pumps; £5,000 for biomass boilers (rural homes only)
- Eligibility Triggers:
- You own your home (England/Wales)
- Replacing fossil fuel heating (oil, LPG, coal)
- Property has a valid EPC with no “recommended loft insulation” notes
- No income requirements—ideal for non-benefit claimants!
3. Great British Insulation Scheme (GBIS): Extra Efficiency Upgrades
- Pair with ECO4: Free cavity wall/loft insulation if your EPC is D-G and council tax band is A-D (England/Wales)
- Cuts heat loss by 30%, making new boilers more effective
The 5-Point Eligibility Checklist (Do You Qualify?)
Cut through the complexity. You likely qualify for a free boiler grant if:

- Over 8 years old, non-condensing, or breaking down frequently
- Your HOME IS ENERGY-INEFFICIENT
- EPC rating of D, E, F, or G (Check yours here)
- You OWN OR RENT YOUR HOME
- Homeowners: Full eligibility
- Private tenants: Landlord permission required (they pay nothing!)
- Excluded: Social housing (council responsibility) and new builds
- Your HOUSEHOLD INCOME IS UNDER £31K
- Even without benefits, use ECO4 Flex via councils (e.g., Liverpool approved a family earning £26k)
Pensioners Note: Pension Credit guarantees eligibility. Over 60s should apply NOW—76% miss out due to unawareness.
