What is the ECO4 scheme?
ECO4 (Energy Company Obligation, phase 4) is a UK government energy-efficiency scheme administered by Ofgem. It supports eligible households with heating and insulation funding intended to make homes warmer and more efficient.
Support depends on household circumstances, property condition, assessment results, supplier criteria and available funding.
Qualifying does not automatically mean every measure will be available for your home.
Support is delivered through obligated energy suppliers and their approved installation partners.
The scheme is currently scheduled to end on 31 December 2026, and availability may reduce before that date.

Who may be eligible for ECO4 funding?
ECO4 eligibility considers your household, income, benefits, and the energy efficiency of your property. The checklist below covers common qualifying factors, but only a full assessment can confirm what support may be available.
- The household receives a qualifying benefit
- The property has a low energy-efficiency rating (typically EPC D–G)
- The household has a low income or is vulnerable to living in a cold home
- The household may qualify through an eligible local-authority referral route (LA Flex)
- The applicant is a homeowner or an eligible private tenant (with landlord consent)
- The proposed improvement is suitable for the property
- Funding remains available through the relevant provider

- ECO4 is not a completely free grant; customers may be required
- Any contribution will be explained before you agree to proceed.
- You will receive a written quotation or proposal.
- No installation begins until scope, funding and any contribution are agreed.
- Eligibility checks and initial enquiries do not guarantee funding.
