The Energy Company Obligation (ECO4) is a UK government scheme that requires large energy suppliers to fund energy-efficiency improvements in homes across the country.
ECO4 specifically helps low-income households, families on means-tested benefits, and properties with poor energy performance certificates (EPC ratings D–G). The scheme runs until 2026 and provides fully-funded home upgrades worth thousands of pounds — with no upfront cost to eligible homeowners and tenants.
Check your eligibility in minutes. We connect you with trusted, government-approved ECO4 installers who manage your application, arrange surveys, and complete installations — all at no cost to you.
Yes, tenants can apply for ECO4 with landlord permission. The landlord must consent to the improvements being made to the property.
Not necessarily. While receiving certain benefits helps you qualify, you may also be eligible based on low income, fuel poverty, or having a low EPC rating.
The process typically takes 4-8 weeks from initial assessment to installation, depending on the complexity of the work required.
For eligible households, ECO4 is fully funded by energy companies. You should not have to pay anything out of pocket.
ECO4 covers insulation (loft, cavity wall, solid wall), heating upgrades, ventilation improvements, and renewable heating systems.
