Free Boiler Replacement Through ECO4
If your boiler is old, broken, or inefficient, you could qualify for a brand new A-rated boiler installed completely free through the government's ECO4 scheme. This includes the boiler, installation, and any necessary pipework.
Who Qualifies?
- You receive qualifying benefits (Universal Credit, Pension Credit, etc.)
- Your home has an EPC of D or below
- Your current boiler is inefficient (typically G-rated or non-condensing)
What Do You Get?
- Brand new A-rated condensing gas boiler
- Full installation including any pipework changes
- New thermostat and heating controls
- All old equipment removed and disposed of
- 1-year manufacturer warranty (most offer 5-10 years)
Private cost for this work: £2,500-£4,500. Through ECO4: £0.
When Does My Boiler Qualify?
Your boiler is likely eligible for replacement if it's:
- Non-condensing (installed before 2005)
- G-rated (below 70% efficiency)
- Broken or beyond repair
- A back boiler (behind a gas fire)
Modern A-rated boilers are 90-94% efficient compared to 60-70% for old models. Upgrading saves £300-400 per year.
