Free Grant Eligibility Assessment
ECO4 Eligibility Check helps UK homeowners understand whether they may qualify for government-supported energy efficiency improvements under the ECO4 scheme. LAMTANS Engineering provides guidance on eligibility routes, qualifying benefits, EPC requirements, and available insulation and heating upgrades to help households explore suitable retrofit support.
⏰ ECO4 extended — now open until 31 December 2026
The Scheme
ECO4 (Energy Company Obligation) requires larger energy suppliers to fund insulation and heating upgrades for low-income households and those living in energy-inefficient homes.
Key dates: ECO4 was due to end on 31 March 2026 but has been extended to 31 December 2026. Cost to eligible households: typically £0 — though some measures attract partial funding and may require a top-up contribution (we always confirm before any work).
All work is delivered under PAS2035 retrofit standards by TrustMark registered installers.

Five Quick Steps
The ECO4 eligibility checker helps you understand whether you may qualify for fully funded insulation and heating upgrades. It considers your benefits, EPC rating, property type and insulation levels — and our free assessment covers every route, including local authority flex options.
Do you or anyone in your household receive any of the qualifying benefits listed above? If yes, you are likely to qualify.
Find your EPC rating at gov.uk/find-energy-certificate. If your rating is D, E, F or G, you may qualify via the low EPC route.
ECO4 covers most property types — houses, bungalows, flats and park homes. Some restrictions apply to certain flat types.
If your home already has adequate insulation, ECO4 may not fund additional insulation — but may fund heating upgrades instead.
We check your eligibility against every route — benefits, low EPC and local authority flex — and confirm your options within 72 hours following your free survey.
Real-World Scenarios
The following examples show how ECO4 eligibility can work in practice, based on benefits, income, EPC ratings and local authority flex rules. These scenarios are for illustration only — every household is assessed individually, and your free assessment confirms what applies to you.
Sarah receives Universal Credit and her home has no loft insulation. She would likely qualify for fully funded loft insulation. Likely cost to Sarah: £0.
David works full-time, earns £35,000 and receives no benefits — but his home has an EPC rating of E, and his local council operates flex rules for EPC D–G homes. He would likely qualify for fully funded cavity wall insulation. Likely cost to David: £0.
Margaret receives Pension Credit (Guarantee Credit) and has an old boiler. She would likely qualify for a fully funded boiler upgrade and heating controls. Likely cost to Margaret: £0.
James receives Child Benefit for two children and his household income is under the threshold. He would likely qualify for internal wall insulation — note that IWI sometimes attracts partial funding, so a top-up contribution may apply.
Lisa owns her home, works full-time, earns £50,000, receives no benefits, and her home already has a good EPC rating of C. She would not qualify for ECO4 — but she can still get a free private quote from us.
Illustrative examples only — eligibility is always confirmed by a full assessment against current scheme rules, and funding levels vary by measure and property.
What's Funded
ECO4 provides funding for a wide range of home energy efficiency improvements designed to reduce heating costs and improve EPC ratings. Eligible households may receive fully funded or partially funded upgrades depending on their property type and assessment outcome.
| Measure | Funding for Eligible Households |
|---|---|
| Loft insulation | ✅ Fully funded if eligible |
| Cavity wall insulation | ✅ Fully funded if eligible |
| Internal wall insulation | ✅ Partial funding — top-up may be needed |
| External wall insulation | ✅ Partial funding — top-up may be needed |
| Underfloor insulation | ✅ Fully funded if eligible |
| Solid floor insulation | ✅ Partial funding — top-up may be needed |
| Park home insulation | ✅ Fully funded if eligible |
| First-time central heating | ✅ Fully funded if eligible |
| Gas boiler upgrade | ✅ Fully funded if eligible |
| Heating controls | ✅ Fully funded if eligible |
| Air source heat pump | ✅ In some cases |
| Solar panels | ✅ In some cases — typically for electric heating homes |
Transparent top-ups: if your home needs partial top-up funding (for example, external wall insulation costing more than the grant covers), we quote the difference clearly before you agree to anything.

|---|---|---|
| Status | Open until 31 Dec 2026 | Launching 2026 (date TBC) |
| Funding source | Energy suppliers | Direct government funding |
| Eligibility | Low-income, benefits, low EPC | Expected broader than ECO4 (details TBC) |
| Measures | Insulation, heating, some solar | Insulation, solar, heat pumps, wider (expected) |
| Cost to household | Typically £0 for eligible households (top-up possible on some measures) | Expected £0 for eligible households (details TBC) |
What you should do now: if you need insulation or heating upgrades, do not wait for the Warm Homes Plan — ECO4 is open until 31 December 2026, and eligibility can be checked today.

Common Questions
No. ECO4 is not a loan — there is nothing to repay. Where a measure attracts partial funding, any top-up contribution is quoted clearly before you agree to anything.
Yes, private tenants can apply with written permission from their landlord. Social housing tenants should contact their housing association first.
You may qualify for the Warm Homes: Local Grant (typically for household incomes under £36,000) or the Warm Homes Plan (expected from 2026). Contact us for a free check across all schemes.
From initial contact to installation is typically 4–8 weeks, depending on funding approval and the measures involved.
ECO4 has been extended to 31 December 2026. Supplier funding is finite, so it's worth checking your eligibility sooner rather than later.
Yes. We are TrustMark Registered, RECC Accredited and PAS2035 Compliant, and we are fully industry accredited — you can verify every membership on our accreditations page. TrustMark registration and PAS2035 compliance are both requirements for ECO4 work.
