As Britain faces rising energy bills and an ongoing cost‑of‑living crisis, the government’s ECO4 scheme continues to play a crucial role in helping households cut heating costs and improve energy efficiency. But for many families with mixed immigration status, eligibility rules have often been confusing and difficult to navigate. The good news is that 2025 has brought updated ECO4 rules designed to be fairer, clearer, and more inclusive. For thousands of households in Manchester, Birmingham, Leeds, London, and across the UK, these changes could open the door to free boiler replacements, insulation upgrades, and other vital home improvements. In this article, Reliant Energy Solutions breaks down the new ECO4 rules, explains what they mean for mixed‑status households, and offers a step‑by‑step guide to securing your grant.
Why ECO4 Matters in 2025?
The Energy Company Obligation (ECO4) is a government‑backed scheme designed to reduce fuel poverty and improve energy efficiency in UK homes. With energy bills remaining high and the cost‑of‑living crisis continuing, ECO4 provides free or heavily subsidised:
- New A‑rated boilers
- Cavity wall and loft insulation
- Solid wall insulation
- Room‑in‑roof insulation
- Heating controls and smart thermostats
For households already struggling in cities like Glasgow, Cardiff, Nottingham, and Liverpool, these upgrades can cut bills by hundreds of pounds every year while also helping the UK meet its net zero 2050 goals.
The Challenge for Mixed‑Status Households
Many families in the UK are mixed‑status households — where one person is a British citizen or settled resident, while others may hold visas, pre‑settled status, or have limited leave to remain.
In the past, these households faced big problems:
- Installers often rejected applications if all members didn’t meet immigration criteria.
- Confusion over benefit entitlements left many unsure if they qualified.
- Local councils sometimes gave conflicting advice, leaving families in limbo.
Take the example of a family in Bradford: a British mother receives Universal Credit, her partner has pre‑settled status, and their children were born in the UK. Before ECO4 2025, they might have been wrongly told they were ineligible. Today, that has changed.
ECO4 2025: Key Eligibility Updates
Here are the biggest updates for mixed‑status households this year:
1. Applicant‑Focused Eligibility
Only the main applicant — the person applying — must prove:
- They have the right to reside in the UK
- They receive a qualifying benefit
Other household members’ immigration status will not affect the application.
2. Expanded Benefit List
In 2025, more benefits now qualify, including:
- Universal Credit
- Pension Credit
- Child Tax Credit
- Income Support
- Housing Benefit
- Jobseeker’s Allowance
This means more families in places like Leicester, Sheffield, and Newcastle are now eligible.
3. Higher Income Thresholds under LA Flex
Local authorities can approve ECO4 applications for households earning up to £31,000, even if they don’t receive standard benefits. This “LA Flex” route is especially useful in mixed‑status households where not everyone can access benefits.
4. Property Requirements
- Homes must have an Energy Performance Certificate (EPC) rating of D or lower
- Both homeowners and private tenants can apply (tenants will need landlord consent)
- Social tenants should apply via their housing association or council
Step‑by‑Step: How Mixed‑Status Households Can Apply?
Here’s how to boost your chances of success:
- Identify the Eligible Applicant
- Choose the adult with the strongest case (UK citizen, settled status, or benefit recipient).
- Check Your EPC Rating
- Use the government’s EPC register to see if your home qualifies. If not, Reliant Energy Solutions can help arrange an assessment.
- Gather the Right Documents
- Proof of benefit entitlement
- Passport or biometric residence permit for the applicant
- Recent utility bill or council tax letter
- Landlord permission (if renting)
- Consider the LA Flex Route
- If you don’t meet the benefit criteria but still struggle with energy bills, Reliant Energy Solutions can work with your local council to apply via LA Flex.
- Apply Early
- ECO4 funding is limited, and installer quotas fill up quickly, especially in high‑demand areas like London, Manchester, and Birmingham.
Common Problems (and How to Solve Them)
Problem 1: “One member of my household has No Recourse to Public Funds (NRPF).”
Solution: As long as the main applicant qualifies, other members’ NRPF status won’t stop you from getting ECO4 support.
Problem 2: “I’m a private tenant and my landlord is not responsive.”
Solution: Reliant Energy Solutions can contact your landlord directly and explain how ECO4 improvements add value to their property.
Problem 3: “I don’t know if I’m on the right benefit.”
Solution: We provide a free eligibility check to confirm whether your benefits qualify.
Problem 4: “My EPC is too high.”
Solution: Some councils allow ECO4 Flex applications if you can show high energy costs or health vulnerabilities — even with a higher EPC.
