Frequently asked questions
What is the ECO4 scheme?
ECO4 (Energy Company Obligation 4) is a government-mandated scheme where large energy suppliers fund free home energy improvements for low-income and fuel-poor households. Ofgem administers the scheme. Qualifying your area households may receive free insulation, first-time central heating, air source heat pumps, or storage heaters at no cost.
Am I eligible for ECO4 in your area?
To qualify, your household must receive a qualifying benefit such as Universal Credit, Pension Credit, Child Tax Credit, Working Tax Credit, Income Support, Housing Benefit, ESA, or JSA, and your home must have an EPC rating of D, E, F, or G. Households in deprived areas may also qualify through the Local Authority Flex route even without a qualifying benefit.
What can I get for free under ECO4?
Qualifying your area households can receive free loft insulation, cavity wall insulation, solid wall insulation (internal or external), underfloor insulation, flat roof insulation, first-time central heating systems, air source heat pumps, and storage heaters. The exact measures depend on your property type, current heating system, and EPC rating, confirmed during a free home survey.
How much is an ECO4 grant worth?
ECO4 grants can cover home energy improvements worth up to £15,000 per property. The total depends on which measures your home needs and qualifies for. All approved measures are fully funded with no upfront cost to the household.
How do I apply for ECO4 in your area?
Complete the eligibility check above. It takes about 60 seconds. If you pre-qualify, an Ofgem-registered installer serving your area will contact you to arrange a free home survey. The installer submits the grant claim to the energy supplier on your behalf.
Is ECO4 still running?
Yes. The ECO4 obligation runs until March 2026, and many energy suppliers continue to accept new applications for qualifying households. Submit your eligibility check now to find out whether your your area property qualifies before the current obligation period ends.
