The ECO4 FLEX Scheme is part of the UK government’s Energy Company Obligation (ECO) initiative, designed to help low-income households improve their home’s energy efficiency. Under this scheme, eligible homeowners and tenants can receive funding for upgrades such as insulation, heating systems, and renewable energy installations.
In this complete guide, we’ll explain what ECO4 FLEX is, who qualifies, and how you can apply to start saving on energy bills while reducing your carbon footprint.
What is the ECO4 FLEX Scheme?
The ECO4 FLEX (Flexible Eligibility) scheme is the final phase of the ECO programme, running until March 2026. It gives local councils the flexibility to identify households in need, even if they do not meet the standard ECO4 criteria.
This approach ensures that more vulnerable residents can benefit from energy efficiency improvements funded by large energy suppliers.
Key Benefits of the ECO4 FLEX Scheme
- Free or subsidised home upgrades such as loft insulation, wall insulation, or heat pumps.
- Lower energy bills through improved energy efficiency.
- Reduced carbon emissions for a greener home.
- Support for vulnerable households who might not meet normal ECO4 rules.
Who is Eligible for ECO4 FLEX?
Under the flexible eligibility rules, you may qualify if:
- You have a low income (usually under £31,000 household income per year).
- Your home has poor energy efficiency (EPC rating of D, E, F, or G).
- You receive certain benefits such as Universal Credit, Income Support, or Pension Credit.
- You are vulnerable due to health conditions made worse by cold homes.
Local authorities can set their own criteria, so it’s worth checking directly with your council.
How to Apply for ECO4 FLEX
- Check your eligibility using your local council’s guidance.
- Contact an approved ECO4 installer or your energy supplier.
- Submit the required documents (proof of income, benefits, and EPC rating).
- Home survey to assess what improvements are needed.
- Installation of upgrades – usually within weeks of approval.
Types of Improvements Available
- Loft insulation
- Cavity wall insulation
- Solid wall insulation
- First-time central heating
- Air source heat pumps
- Solar panels (in some cases)
Why Apply Now?
Funding is limited and the scheme ends in March 2026. Applying early increases your chances of receiving full funding before budgets run out.
