Free Boiler Replacement Grant under ECO4 Scheme
Are you struggling with an old, inefficient boiler that costs a fortune to run and barely keeps your home warm? You’re not alone — thousands of UK households are facing similar issues. Fortunately, the Free Boiler Replacement Grant under the ECO4 Scheme could be exactly what you need to cut energy costs and improve your home’s comfort. This government-backed initiative is specifically designed to support low-income households across the UK by providing access to free boiler upgrades and other home energy efficiency improvements — all at zero cost to you.
With energy bills constantly on the rise, replacing your outdated boiler with a new, energy-efficient model can make a huge difference in both your heating performance and your monthly expenses. In this article, we’ll explain everything you need to know about the ECO4 Scheme — including how it works, who is eligible, the types of boilers covered, and the simple steps you need to follow to apply.
Old boilers—especially those made before 2005—waste a lot of energy and can cost you more money in the long run. They’re less efficient and more likely to break down. Getting a new, energy-efficient boiler grant through the ECO4 scheme can make a big difference:
Upgrading to a modern condensing boiler isn’t just about staying warm—it’s about saving money month after month. New, energy-efficient boilers are built to use fuel much more effectively than older models. That means less gas is needed to heat your home, which leads to lower energy bills. Over time, these savings really add up, putting more money back in your pocket while keeping your home cozy and comfortable.
Switching to a modern, energy-efficient combi boiler doesn’t just save you money—it helps the planet too. Older boilers waste a lot of energy, burning more fuel and releasing more carbon into the atmosphere. With a free upgrade through the ECO4 scheme, you could receive a top-rated boiler like the Ideal Logic+ Combi, Vaillant ecoTEC Plus, or Worcester Bosch Greenstar—all known for their high efficiency and low emissions. These A-rated models are designed to reduce your energy use, cut down your carbon footprint, and keep your home comfortably warm all year round. It’s a smart move for your wallet and the environment.
There’s nothing worse than waking up to a cold home or dealing with surprise boiler breakdowns in the middle of winter. With a new gas boiler installed through the ECO4 scheme, you can enjoy steady, reliable heating and hot water whenever you need it. Say goodbye to chilly mornings, costly repairs, and the stress of an old, unreliable system. Instead, enjoy a cosy, comfortable home all year round—knowing your grant boiler is working quietly and efficiently in the background, keeping you and your family warm without worry.

The Energy Company Obligation (ECO4) Scheme is the fourth phase of a government initiative aimed at reducing carbon emissions and tackling fuel poverty. Running from 2022 to 2026, ECO4 focuses on improving the energy efficiency of homes across the UK, especially those belonging to low-income and vulnerable households.
One of the major benefits of the ECO4 Scheme is the Free Boiler Replacement. This allows eligible homeowners to have their old, inefficient boilers replaced with modern, energy-efficient condensing boilers — completely free of charge.

Modern condensing boilers are super efficient—they use up to 98% of the energy to heat your home, wasting very little. But if your boiler is 20 years old, it might only use about 75% of the energy effectively. Older boilers can be even less efficient, sometimes only 60%. That means a lot of the money you spend on heating is being wasted. Upgrading to a new system boiler can make your home warmer and help you save money on your energy bills.
The Free Boiler Replacement Grant under the ECO4 Scheme is a golden opportunity for UK households to upgrade their heating system without spending a penny. With rising energy costs and the push for greener living, there’s never been a better time to switch to an energy-efficient boiler.
Make your home warmer, more efficient, and cost-effective — all with the help of a government-backed grant. Let heat1 make it easy for you.
