Background: The ECO4 Scheme and Its Relevance in 2025
The Energy Company Obligation (ECO) scheme, now in its fourth phase (ECO4), is the UK government’s flagship programme to reduce carbon emissions and tackle fuel poverty. The scheme’s primary focus is upgrading inefficient heating systems in low-income homes, offering free or heavily subsidised boiler replacements to qualifying households. As of 2025, ECO4 has expanded its reach, now covering more properties with slightly relaxed criteria—making it a critical opportunity for many UK residents.
Why does this matter?
- Energy bills remain a top concern for UK households, with heating accounting for over 60% of domestic energy use.
- Upgrading to an efficient boiler can slash annual energy costs by up to £500 and significantly reduce carbon emissions.
- The government’s Net Zero targets and the ongoing cost-of-living crisis make ECO4 more relevant than ever.

|---|---|---|---|---|
| ECO4 | Boiler 8+ years, EPC D or below, low income/benefits | Free/reduced boiler | Homeowners, private tenants | Most comprehensive; covers insulation too |
| GBIS | EPC D or below, low income/benefits | Insulation, some boilers | Homeowners, some private tenants | Primarily insulation; some overlap with ECO4 |
| Boiler Upgrade Scheme | Valid EPC, replace fossil heating | Heat pump/grant | Homeowners | Targets low-carbon upgrades, not traditional boilers |
