The ECO4 (Energy Company Obligation, Phase 4) is a UK government-backed programme that helps lower-income and vulnerable households improve home energy efficiency. It funds measures such as insulation, boiler upgrades, and certain low-carbon heating measures to reduce fuel poverty and carbon emissions. Operators follow rules and eligibility guidance set by Ofgem.
Eligibility is primarily based on household circumstances and property efficiency. Common routes to qualify include receiving qualifying means-tested benefits (e.g., Universal Credit, Pension Credit) or being nominated under “flexible eligibility” by local authorities or approved partners. Properties with poor EPC ratings (typically D–G) are prioritised for measures. If you’re unsure, we’ll check your eligibility quickly and for free.
ECO4 can fund loft insulation, cavity/internals/external wall insulation, boiler replacements and repairs, heating controls, and some low-carbon technologies like heat pumps or solar where appropriate. The exact measures depend on your home’s condition and assessment.
You can apply through our website form or call us. We’ll perform a free eligibility check, review your benefits/EPC and, if eligible, arrange a home survey and installation with our certified contractors. Typical process: eligibility check → survey → approval → installation.
