ECO4 Scheme in the Black Country: Are You Eligible? (2026 Guide)

Who qualifies for free insulation under ECO4, the two routes to eligibility, and how to apply through your Black Country council before the scheme closes.

The ECO4 scheme is a government energy efficiency programme that funds free insulation and heating improvements for lower-income and vulnerable households in Great Britain. It runs until 31 December 2026. In the Black Country, households can qualify in two ways. The benefit-based route covers anyone receiving a means-tested benefit such as Universal Credit, Pension Credit, Income Support, Child Tax Credit, Working Tax Credit or Housing Benefit. The LA Flex route, run separately by City of Wolverhampton Council, Walsall Council, Dudley Metropolitan Borough Council and Telford & Wrekin Council, opens funding to households without a qualifying benefit who meet local income, health or fuel-poverty criteria. Eligible homes can receive cavity wall, loft, solid wall and floor insulation at no cost. Around 59% of Wolverhampton homes sit in the EPC D to G bands that the scheme targets, so a large share of local households qualify. A free eligibility check confirms your route.

If your home is cold, your bills are high, and you have heard that the government will pay for insulation, ECO4 is probably the scheme you are thinking of. It is the largest source of free insulation funding in the Black Country, and a great many local homes qualify. The catch is that the rules are not obvious, and the scheme closes at the end of 2026. This guide explains exactly who is eligible and how to apply.

What is the ECO4 scheme?

ECO stands for the Energy Company Obligation. It is a government scheme that requires the larger energy suppliers to fund energy efficiency improvements in lower-income and vulnerable homes. We are now in its fourth phase, ECO4, which began in 2022 and runs until 31 December 2026. Under it, eligible households can have cavity wall, loft, solid wall and floor insulation installed free of charge, often alongside heating upgrades.

Route one: benefit-based eligibility

The simplest way to qualify is by receiving a means-tested benefit. If you or someone living in your home receives any of the following, your property is very likely eligible:

  • Universal Credit
  • Pension Credit (Guarantee Credit or Savings Credit)
  • Income Support
  • Income-based Jobseeker's Allowance (JSA)
  • Income-related Employment and Support Allowance (ESA)
  • Child Tax Credit and Working Tax Credit
  • Housing Benefit

The property also needs to fall within the EPC bands the scheme targets, typically D to G, which the vast majority of older Black Country homes do.

Route two: LA Flex (no benefit needed)

Many households that genuinely need help do not claim a qualifying benefit, for example pensioners on a modest private income or families just above the benefit threshold. LA Flex, or Local Authority Flexible Eligibility, exists for exactly these cases. It lets each council set its own additional criteria and declare a household eligible for ECO4.

In our area, City of Wolverhampton Council, Walsall Council, Dudley Metropolitan Borough Council and Telford & Wrekin Council each publish their own Statement of Intent setting out their LA Flex rules. The criteria usually include one or more of:

  • A total household income below a set threshold (commonly around £31,000, but it varies by council).
  • A resident with a health condition made worse by living in a cold home, such as a respiratory, cardiovascular or limited-mobility condition.
  • Living in a postcode or area identified as being at high risk of fuel poverty.

Because the rules differ between councils, the LA Flex route is where local knowledge helps most. We identify which council covers your address, check your circumstances against its criteria, and complete the declaration for you.

How to apply through your Black Country council

  1. Check your eligibility. Confirm whether you qualify through a benefit or through LA Flex. We do this free.
  2. Book a free survey. An accredited surveyor assesses your property, its EPC band and which measures it needs.
  3. Funding approval. We submit the application, including any council LA Flex declaration, to secure the funding.
  4. Installation. Once approved, a TrustMark registered installer fits the measures at no cost to you.

Why the December 2026 deadline matters

ECO4 is funded only until 31 December 2026. As the deadline approaches, demand rises and the availability of surveyors and installers tightens. Leaving an application to the last few months risks missing out if capacity runs short. If you think you might qualify, the sensible move is to get your free eligibility check done now, well ahead of the cut-off.

Frequently asked questions

What benefits qualify me for ECO4?

Qualifying benefits include Universal Credit, Pension Credit (Guarantee or Savings Credit), Income Support, income-based Jobseeker's Allowance, income-related Employment and Support Allowance, Child Tax Credit, Working Tax Credit and Housing Benefit. If you receive any of these, your home is very likely eligible for free insulation under ECO4.

Can I get ECO4 if I do not claim any benefits?

Yes, potentially, through the LA Flex route. Each Black Country council can extend ECO4 to households without a qualifying benefit who meet local criteria such as a low household income, a resident with a cold-sensitive health condition, or living in a fuel-poverty area. We help you apply through the right council.

Does ECO4 really end in December 2026?

Yes. ECO4 is funded to run until 31 December 2026. While successor schemes are likely given current energy policy, the rules and funding of any future scheme are not guaranteed, so the safest approach is to apply under ECO4 while it is open.
