Quick Facts: What You Need to Know
The ECO4 scheme offers £4 billion in government funding until March 2026

The Energy Company Obligation scheme (ECO4) represents the UK government's commitment to tackling fuel poverty and reducing carbon emissions. Launched to help vulnerable households, this initiative requires larger energy companies to fund energy-efficiency improvements in homes across the country.
Unlike loans or subsidies, ECO4 grants provide completely free installations with no repayment necessary. The scheme specifically targets homes with poor energy efficiency ratings (EPC D-G) and households receiving qualifying benefits. From replacing ancient boilers to installing cutting-edge heat pumps, the programme covers a comprehensive range of measures designed to slash your energy bills and keep your home warm throughout winter.
According to the official government consultation, the scheme aims to improve energy efficiency for over 500,000 homes before the March 2026 deadline. The urgency is real once the funding runs out, there’s no guarantee of extension.
Am I Eligible? ECO4 Scheme Eligibility 2025 Checker
Understanding your ECO4 scheme eligibility 2025 status is straightforward. The programme uses two main criteria: your household income and your property’s current energy efficiency.
Income-Based Eligibility
You automatically qualify if you or anyone in your household receives any of these benefits:
Universal Credit
Pension Credit (Guarantee or Savings Credit)
Income Support
Job Seekers Allowance (income-based)
Employment and Support Allowance (income-related)
Working Tax Credit
Child Tax Credit
Child Benefit (for households with a combined income under £31,000)
Disability Living Allowance
Personal Independence Payment
Attendance Allowance
Carer’s Allowance
Industrial Injuries Disablement Benefit
Even if you’re not receiving benefits, you might still qualify through the flexible eligibility route if your annual household income is below £31,000 and you live in a property with poor energy efficiency.
Property-Based Requirements
Your home must have an Energy Performance Certificate (EPC) rating of D, E, F, or G to qualify for most measures. Properties with higher ratings may still qualify for specific upgrades depending on circumstances. Both homeowners and private tenants can apply, though tenants need landlord permission for major installations.
The ECO4 official website provides detailed guidance on checking your specific eligibility status and understanding which measures your property qualifies for.
What Free Upgrades Can You Get?
Available ECO4 Measures
Government-backed upgrades to cut bills and carbon — tailored to your home.
Free Boiler Replacement UK
If your boiler is 15 years or older, you may qualify for a new A-rated condensing boiler.
Modern systems convert up to 90% of fuel into usable heat — older models only 60–70%.
Households save £300–£500 yearly after a boiler grant installation.
Check eligibilityHeat Pump Installation
Air or ground-source systems provide efficient, low-carbon heating and hot water.
Reduce heating costs by up to 40% compared with old oil or electric systems.

- Cavity wall — trap heat between walls
- Loft insulation — stop warmth escaping through your roof
- Solid wall — internal or external insulation
Solar Panels & Additional
- Smart heating controls
- Room-in-roof insulation
- Energy-efficient glazing
- Park home insulation
If your boiler is 15 years or older, you’re likely eligible for a brand-new A-rated condensing boiler. These modern systems are dramatically more efficient than older models, converting up to 90% of fuel into usable heat compared to just 60-70% for outdated boilers.
The difference shows immediately in your bills. Households typically save £300-500 annually after a boiler grant installation. That’s money back in your pocket every single year, and with a new boiler lasting 10-15 years, the lifetime savings are substantial.
For homes suitable for renewable heating, ECO4 covers air source or ground source heat pump installations. These systems extract heat from the air or ground, providing efficient, low-carbon heating and hot water. While heat pumps work differently from traditional boilers, they can reduce heating costs by up to 40% compared to old oil or electric systems.
Poor insulation is like heating the outdoors—your warmth simply escapes through walls, roofs, and floors. ECO4 covers:
Cavity wall insulation: Filling the gap between exterior and interior walls to trap heat
Loft insulation: Preventing heat loss through your roof (the biggest source of heat escape)
Solid wall insulation: For properties without cavity walls, external or internal wall insulation
Through the solar panels grant programme, eligible households can receive free solar PV installations, generating electricity and reducing bills further. The scheme also covers:
Smart heating controls and thermostats
Room-in-roof insulation
Energy-efficient glazing
Park home insulation
Step-by-Step Application Process
Getting your free upgrades through the ECO4 scheme eligibility 2025 programme is simpler than you might think:
Check Your Eligibility: Verify you meet the income and property requirements using online checkers or contacting approved installers like Simple Green Energy.
Contact an Approved Installer: Work with a certified ECO4 installer who can handle the entire process. They’ll verify your eligibility and explain which measures your home qualifies for.
Schedule Your Free Assessment: A qualified surveyor visits your property to assess current energy efficiency, identify suitable upgrades, and create an installation plan.
Receive Your Installation Plan: You’ll get a detailed breakdown of recommended measures, expected savings, and installation timeline. No hidden costs, no surprises.
Installation Day: Professional installers complete the work, typically within 1-4 days depending on the measures. All work comes with guarantees and meets current building regulations.
Post-Installation Certification: After completion, you receive an updated EPC certificate showing your improved energy rating and documentation for all work completed.
The entire process from application to installation usually takes 3-6 weeks, though this varies by location and installer availability. For Birmingham residents, specialized ECO4 grant services are available with local support.
| Upgrade Type | Installation Value | Annual Saving | 15-Year Saving |
|---|---|---|---|
| New Boiler | £2,500-3,500 | £300-500 | £4,500-7,500 |
| Full Insulation | £3,000-8,000 | £200-350 | £3,000-5,250 |
| Heat Pump | £8,000-12,000 | £400-600 | £6,000-9,000 |

Time is genuinely of the essence with the energy company obligation 2025 programme. Here’s why you shouldn’t delay:
Limited Funding: The £4 billion pot is finite. With growing awareness and rising energy costs driving applications, funding could be exhausted before the official deadline.
Winter Preparation: Applying now means you could have your upgrades completed before winter 2025/26 peaks. Imagine facing the coldest months with a brand-new efficient heating system rather than struggling with an ancient boiler.
No Extension Guaranteed: While previous ECO schemes were extended, there’s no official commitment for ECO5 beyond March 2026. Government priorities and funding can shift.
First-Come, First-Served: Installers work through applications in order. Waiting until late 2025 could mean missing out entirely as demand surges before the deadline.

Real Success Story: The Johnson Family
Sarah Johnson, a single mother of two from Manchester, was spending over £200 monthly on energy bills while her 20-year-old boiler struggled to keep their three-bedroom house warm. Through the free boiler replacement UK programme, her family received a new A-rated boiler, full loft and cavity wall insulation, and upgraded thermostatic controls.
"The transformation was incredible," Sarah explains. "Our bills dropped by £95 a month immediately. The house stays warm without cranking up the heating constantly. My youngest had been suffering from respiratory problems from the damp—that's completely gone now. I genuinely can't believe this was all free through ECO4 grants."
The Johnson family's total installation value exceeded £6,500, with projected savings of over £1,100 annually. Stories like Sarah's are happening across the UK as households discover their ECO4 scheme eligibility 2025 status and take action.
