Can I Get a Grant for a New Boiler?

Thinking of replacing your old boiler but worried about the cost? You’re not the only one. Boiler upgrades can be expensive, but the good news is, you might not have to pay for it all yourself. In fact, if you meet the right conditions, you could get a brand-new boiler completely free.
This guide breaks everything down in plain English. We’ll explain why boiler grants exist, who can get them, and how you can apply—step by step. If you want lower bills and a warmer home, this is well worth a read.

Let’s quickly take away the most important things we will cover:
- Boiler grants exist to make heating more affordable and efficient.
- You could get a free or discounted boiler through ECO4 or the Boiler Upgrade Scheme.
- Most schemes target people with older boilers, low income, or specific benefits.
- The process is simple—check your eligibility, contact an installer, and let them handle the paperwork.
- Even if you don’t qualify for a full grant, other support may still be available.
- A new boiler means lower bills, better heating, and fewer breakdowns.
Why Are There Boiler Grants in the First Place?
You might be wondering: Why would anyone give away the free boiler scheme?
It’s simple. Older boilers waste energy, cost more to run, and pump out more carbon. By helping people upgrade to modern, energy-efficient models, the government and energy companies are aiming to:
- Reduce household energy bills
- Lower carbon emissions
- Improve heating in homes, especially for those who need it most
These schemes aren’t just about saving the planet—they’re about keeping people warm and reducing fuel poverty too.
What Types of Boiler Grants Are Available?
There are a few key programs that offer grants. Some give you money towards a new heating system. Others cover the full cost of installation. Here’s a breakdown:
-
Boiler Upgrade Scheme (BUS)
Available in: England and Wales
This scheme helps households switch from traditional fossil fuel systems (like gas or oil boilers) to greener alternatives, such as heat pumps or, in rural cases, biomass boilers.
You could get:
- £7,500 towards the cost and installation of an air source or ground source heat pump
- £5,000 off a biomass boiler (only for rural, off-grid properties)
Good to know: Your installer must be MCS-certified to apply.
-
The ECO4 Scheme
Available across the UK
This scheme targets low-income households or those receiving certain benefits. It aims to reduce energy waste by offering:
- Free or heavily discounted A-rated boilers (combi and condensing models included)
- Additional upgrades, like insulation, to make your home more energy-efficient
Funded by: Major energy providers—so you don’t have to be their customer to qualify.
-
Local Authority and Charity Grants
Some councils and local organisations offer support if you’re:
- On a low income
- Living in a cold or energy-inefficient home
- Dealing with health conditions worsened by cold environments
These grants often cover not just boilers, but things like insulation, double glazing, and other home improvements.
Do You Qualify for a Boiler Grant?
This is the big question—and the answer depends on a few key things. Most grant schemes look at your income, the state of your current boiler, and where you live.
You may be eligible if:
- You own or privately rent your home
Social housing tenants often have different support routes. - Your boiler is old or inefficient
Usually, it must be over 7 years old and not be working well. - You receive certain benefits, like:
- Universal Credit
- Pension Credit
- Child Tax Credit
- Income Support
- Housing Benefit
- Working Tax Credit
- Your home has an Energy Performance Certificate (EPC)
Some schemes require a minimum EPC rating. Others focus on homes that are off the gas grid or in rural areas. - You haven’t already received similar funding
If you’ve recently had support for installing a heat pump or biomass boiler, you may not be able to apply again.
How Do You Apply for a Boiler Grant?
Luckily, the application process is straightforward and often handled by the installer.
Here’s how it usually works:
Step 1: Check Your Eligibility
Use an online eligibility checker. Many installer websites, as well as government pages, offer tools to help you find out if you qualify in just a few clicks.
Step 2: Contact a Certified Installer
For the Boiler Upgrade Scheme, this must be an MCS-certified professional. They’ll check your property, offer advice, and provide a quote.
Step 3: Let the Installer Handle the Paperwork
In most cases, they’ll apply for the grant on your behalf.
Step 4: Pay the Reduced Cost (or Nothing at All)
If you qualify, the grant is applied directly, so your final bill is lower, or even zero.
What If You Don’t Qualify for a Free Boiler?
Don’t give up just yet.
Even if you’re not eligible for a full grant, you could still get a discounted boiler or other forms of help. Many local councils run “Eco Flex” schemes, which support households who:
- Are on low incomes
- Don’t claim benefits, but still struggle with high energy bills
- Live in cold or inefficient homes
These programs often consider your situation on a case-by-case basis. It’s always worth asking.
What Are the Benefits of Getting a New Boiler Through a Grant?
Let’s say you qualify. Is it really worth it? Absolutely.
Here’s what you can expect:
- Lower Energy Bills
New boilers are far more efficient. That means less gas, lower bills, and more savings each month. - Better Heating Performance
Modern systems heat your home faster and more evenly—no more freezing corners in winter. - Fewer Breakdowns
New boilers are more reliable, giving you peace of mind when it’s coldest. - A Smaller Carbon Footprint
Cutting down on energy use is better for the environment—and your wallet
Final Thought
Boiler grants in Wales are out there for a reason—to help you stay warm without breaking the bank. Whether you qualify for a full grant or just need help covering part of the cost, now’s the time to explore your options. Why keep paying more to heat your home when support could be just a few clicks away?
