Is your old back boiler costing you more money than it should — or worse, putting your safety at risk? In 2025, thousands of UK households could qualify for a Free Back Boiler Replacement Grant through government-backed schemes like ECO4. If your boiler was installed before 2005, now is the time to replace it with a safe, energy-efficient A-rated boiler — and you might not have to pay a penny.
At Prisma Services, we help homeowners and tenants replace outdated back boilers through the Free Boiler Scheme, fully funded by major energy suppliers. With energy bills still sky-high in 2025 and older boilers being phased out, there’s never been a better time to apply.
Let’s break down what the grant covers, who qualifies, and how you can apply step-by-step.
What Is the Free Back Boiler Replacement Grant?
The Free Back Boiler Replacement Grant is part of the UK Government’s Energy Company Obligation scheme (ECO4). Its aim? To reduce fuel poverty and carbon emissions by upgrading old, inefficient heating systems in low-income homes.
If you currently have a back boiler — often hidden behind a gas fire and installed before 2005 — you could be eligible for a brand-new A-rated condensing boiler completely free of charge.
Here’s what you could get under the Free Back Boiler Replacement Scheme:
- Free removal of your outdated back boiler
- Free installation of a new A-rated condensing boiler
- Smart heating controls (e.g. thermostat, timers)
- Optional insulation upgrades (loft, cavity wall)
- Work completed by Gas Safe registered engineers
All 100% government-funded. No hidden fees. No upfront costs.
Why Are Back Boilers Being Replaced in 2025?
Back boilers were once a popular heating solution — typically installed behind fireplaces and built into older properties. But in 2025, they’re now considered highly inefficient and even dangerous in some cases.
Here’s why they’re being replaced:
Back boilers waste 30-50% more energy compared to modern condensing boilers
Many don’t comply with current Building Regulations
Spare parts are no longer widely available
They’re prone to carbon monoxide leaks and breakdowns
The UK government and Ofgem are encouraging homeowners to move away from these outdated systems by offering 100% funded boiler replacements through the ECO4 scheme.
By replacing your back boiler, you could:
Save £300–£600 annually on energy bills
Heat your home more effectively and safely
Reduce your carbon footprint
Comply with 2025 heating efficiency regulations
Who Is Eligible for the Back Boiler Replacement Grant?
You could qualify for a Free Back Boiler Replacement Grant if:
You are a homeowner or rent privately
Your current boiler is a back boiler or non-condensing model (installed pre-2005)
