What Is the ECO4 Scheme?
The Energy Company Obligation (ECO4) is a government-mandated scheme requiring large energy suppliers in the UK to fund energy-efficient improvements for qualifying households. Running from April 2022 to March 2026, ECO4 replaced ECO3 with updated eligibility and broader support.
Its goal is to help low-income or fuel-poor homes reduce energy bills and carbon emissions. The scheme covers a range of upgrades including:
- Free boiler replacement
- Loft and cavity wall insulation
- Solid wall insulation
- Air source heat pumps (where applicable)
- Solar panels for off-grid homes
💡 Insight: According to Ofgem, over 450,000 homes benefitted from ECO schemes in 2023 alone, saving an average of £300–£500 annually on energy bills.
Who Is Eligible for ECO4 in 2025?
Eligibility focuses on low-income households, those in fuel poverty, and homes with poor energy efficiency (EPC rating D, E, F, or G). Key qualification criteria include:
- Receiving qualifying benefits (e.g. Universal Credit, Income Support, ESA)
- Owning or privately renting a poorly insulated home
- Living in England, Wales, or Scotland (Northern Ireland has separate schemes)
✅ You may also qualify under LA Flex if your council defines you as fuel-poor—even if you’re not receiving benefits.
💬 Case story: A retired couple in Norfolk qualified under LA Flex and received £9,000 worth of insulation and boiler upgrades for free in 2024.
What Upgrades Can You Get in 2025?
ECO4 funding is tailored based on your property’s needs. After assessment, you may receive:
- Boiler replacement: If your existing boiler is non-condensing or over 15 years old
- Wall insulation: Cavity, internal, or external solid wall
- Loft insulation: Recommended for homes without proper roof insulation
- First-time central heating: For homes without a system at all
- Heat pumps or solar: Only for suitable off-gas properties
📊 Example: A family of four in Manchester received cavity wall insulation, new boiler, and loft insulation—fully funded—reducing their annual gas bill by 40%.
💡 Can You Apply If You’re a Tenant or in Shared Ownership?
Yes—ECO4 is not limited to homeowners. You can apply if you:
- Privately rent from a landlord (with permission)
- Own a share of your home (shared ownership)
- Live in social housing with EPC rating E–G (limited support)
Landlords must approve the work, and some providers require joint application forms. The upgrades remain with the property and benefit current and future tenants.
💬 Example: A tenant in Birmingham got a free boiler and loft insulation with their landlord’s consent under ECO4 in early 2025.
How to Apply for the ECO4 Scheme
The process is simple and involves the following steps:
- Find a registered ECO installer or provider via Simple Energy Advice
- Book a free energy assessment of your home
- Submit benefit documents or use LA Flex route through your council
- Receive an upgrade plan tailored to your home’s needs
- Get the work scheduled—funded entirely by the energy company
⚠️ Note: There are many private “ECO lead generators” online—stick with verified providers or government-listed advice services for safety.

Frequently Asked Questions (FAQ)
What income counts for ECO4 eligibility?
Income is not assessed directly—qualifying benefits or LA Flex status are what matter most. Check with your installer or local council for specific guidance.
Can landlords get funding for multiple properties?
Yes, but each property must have eligible tenants or apply via LA Flex. Landlords cannot apply directly—it must go through the tenant or a lead provider.
Does ECO4 cover heat pumps and solar panels?
Yes, but only for suitable properties—typically off-gas homes with sufficient energy ratings. Not all homes will qualify for renewables.
How long does the application process take?
From assessment to installation, the process typically takes 3–8 weeks depending on your provider and region.
Is there a deadline for applying to ECO4?
The scheme runs until March 2026, but funding is limited each year. Early application is highly recommended for 2025 upgrades.
