Can’t Afford a Boiler Replacement? ECO4 Grants Make It Possible
Replacing an old or inefficient boiler can be one of the biggest household expenses. For many families across the UK, the thought of finding thousands of pounds for a new heating system is simply unrealistic. Yet, living with a broken or outdated boiler often means sky-high energy bills and a cold home during winter.
The good news is that you may not need to pay for a replacement out of your own pocket. Through the ECO4 scheme, qualifying households can secure a free boiler replacement or significant heating upgrades funded by the UK government. If you’ve been worrying about the cost of upgrading your heating system, this article will explain how the ECO4 grant works, who qualifies, and how you can apply today with the support of Cozyfy.
Why Are Boiler Replacements So Costly?
While a modern, energy-efficient boiler is vital for keeping heating bills down, the upfront price of installing one can be daunting. In the UK, the cost of a new boiler typically ranges from £2,000 to £5,000, depending on the type of system, property size, and any extra installation work required.
For families on a tight budget or already struggling with rising energy costs, covering this expense is often impossible. To address this, the government introduced the Energy Company Obligation (ECO4) scheme—an initiative designed to help low-income and vulnerable households enjoy warmer, more energy-efficient homes without the burden of paying thousands of pounds upfront.
How ECO4 Can Improve Your Home
The ECO4 grant is a UK government initiative aimed at cutting carbon emissions while reducing fuel poverty. Under this scheme, energy suppliers are obligated to fund energy-efficient upgrades in eligible homes. Now in its fourth phase—running until March 2026—the ECO4 scheme has broadened its criteria so more households can access vital support.
With ECO4, you may be entitled to:
- A government free boiler grant that covers the full cost of a replacement.
- Replacement of outdated systems, including back boilers.
- Installation of first-time central heating systems.
- Free or significantly reduced insulation measures.
- Support for renewable solutions, such as free heat pump grants.
Thanks to these measures, homeowners and tenants don’t need to postpone crucial upgrades simply because of financial constraints.
How You Can Get a Boiler Replacement for Free
One of the most valuable benefits of the ECO4 scheme is the option to receive a free boiler replacement. If your current boiler is outdated, inefficient, constantly breaking down, or if you still rely on a back boiler (an older style hidden behind a fireplace), you could qualify for a brand-new heating system without paying a penny.
Getting a new boiler is not just about keeping your home warm—it’s also about long-term efficiency and savings. Modern A-rated combi and system boilers are designed to operate with far less energy than older models. This means lower running costs, reduced energy waste, and a smaller carbon footprint. In fact, many households save hundreds of pounds each year simply by upgrading to a new, energy-efficient boiler through the ECO4 grant.
Another key benefit is reliability. Older boilers often need constant repairs, which can quickly add up in cost. By replacing your boiler under the government-backed ECO4 scheme, you’ll enjoy peace of mind knowing your home has a dependable system that works efficiently all year round.
For families across the UK, a government free boiler grant is a game-changer—removing the financial burden of replacement while ensuring a warmer, greener, and more affordable home.
Who Is Eligible for a Free Boiler Grant?
Eligibility for a government free boiler grant depends on several factors, including your household income, the type of property you live in, and whether you receive certain benefits. In most cases, you may qualify if:
- You are a homeowner or a private tenant.
- Your existing boiler is over 20 years old, faulty, or highly inefficient.
- Someone in your household receives qualifying benefits such as Universal Credit, Pension Credit, Income Support, or Child Tax Credit.
- Your property has a low Energy Performance Certificate (EPC) rating of D, E, F, or G.
Even if you’re not currently on benefits, some local councils offer a “flexible eligibility” route under the ECO4 scheme. This means households struggling with high energy bills or poor home efficiency may still be able to access support.

Why It’s Important to Replace a Back Boiler
Many UK households still rely on back boilers, a type of heating system fitted behind fireplaces. While once popular, these systems are now seen as outdated, inefficient, and in some cases even unsafe. Because they no longer meet modern energy standards, back boilers are expensive to run, prone to frequent breakdowns, and increasingly difficult to repair due to a lack of spare parts.
The ECO4 scheme recognises these challenges, which is why properties with back boilers are often given priority for a free boiler replacement grant. By upgrading to a modern A-rated combi boiler, homeowners can cut their energy usage significantly, reduce heating costs, and enjoy a far more reliable system. Another bonus is the extra space—modern boilers are compact, freeing up room in your home where the old back boiler once sat.
The Key Benefits of a Free Boiler Replacement Through ECO4
Securing a government free boiler grant offers far more than just financial relief. Households that qualify for the ECO4 scheme can enjoy a range of lasting advantages, including:
- Zero upfront costs – Both the new boiler and professional installation are fully funded under the scheme, removing the financial barrier to upgrading.
