In 2025, with the rising cost of living and energy prices affecting homes across the UK, the Government’s Eco-Energy Grants are a lifeline for households struggling with inefficient heating and poor insulation. These grants—especially under the ECO4 Scheme—are designed to help low-income, fuel-poor, and vulnerable families make their homes warmer, greener, and more affordable.
If your heating bills are high, your boiler is old, or your home feels freezing in winter, you could be eligible for free boiler replacements, insulation, and even first-time central heating—fully funded by the UK Government.
At Prisma Services, we help eligible homeowners and tenants across the UK apply for and receive these energy-saving upgrades at zero cost. Here’s everything you need to know about how these grants work, who qualifies, and how to apply in 2025.
What Are Eco-Energy Grants in the UK?
Eco-Energy Grants are part of the Energy Company Obligation (ECO) scheme, launched by the UK Government to reduce carbon emissions and tackle fuel poverty. The current phase, called ECO4, runs from 2022 to 2026, and it’s the most generous and inclusive version yet.
Through ECO4, households can access:
- Free Boiler Replacement Grants
- First Time Central Heating Grants
- Free Cavity Wall & Loft Insulation
- Back Boiler Replacement
- Air Source Heat Pump Grants (via the Boiler Upgrade Scheme)
All installations are carried out by certified engineers—and the cost is covered by major energy suppliers.
Who Can Qualify for ECO4 Energy Grants?
Eligibility is mainly based on income, benefits received, and your home’s Energy Performance Certificate (EPC) rating.
You’re likely eligible if:
- Your household income is under £31,000/year (before tax), or
- You receive qualifying benefits, or
- You live in a home with a low EPC rating (D, E, F, or G), and
- Your current boiler is over 15 years old, inefficient, or not working.
Qualifying Benefits for ECO4 (2025)
You may qualify automatically if you receive one or more of the following:
- Universal Credit
- Income Support
- Pension Credit (Guarantee or Savings)
- Housing Benefit
- Income-Based JSA or ESA
- Child Tax Credit
- Working Tax Credit
Prisma Services can assess your eligibility under eco4 scheme in just a few minutes.
What Types of Grants Are Available?
1. Free Boiler Replacement Grant
If your boiler is non-condensing, 15+ years old, or completely broken, you could qualify for a brand-new A-rated boiler—installed for free.
New boilers are up to 90% efficient, helping households save £200–£350/year on energy bills.
2. First Time Central Heating
Never had central heating before? Under ECO4, you could get a full central heating system, including boiler, radiators, and thermostats—completely free.
Perfect for homes using electric heaters, fires, or no heating at all.
3. Free Insulation Grants
Poorly insulated homes lose up to 35% of their heat through walls and roofs.
ECO4 offers:
- Cavity Wall Insulation
- Loft Insulation
- Underfloor Insulation
- Internal Wall Insulation (for solid walls)
This makes homes warmer, quieter, and cheaper to heat.
4. Back Boiler Replacement
Back boilers are outdated, inefficient, and often unsafe. ECO4 will remove your old back boiler and replace it with a modern, condensing system—safer, cleaner, and more cost-effective.
5. Air Source Heat Pump Grants (Boiler Upgrade Scheme)
Eco4 works alongside the Boiler Upgrade Scheme (BUS), offering up to £7,500 towards installing air source heat pumps—an eco-friendly, future-proof heating solution that lowers your carbon footprint.
