If you’re wondering how much the government boiler grant is, you’re not the only one. With soaring energy bills and the drive for greener homes, UK households are researching this scheme to make a difference. The Free Boiler Grant under the ECO4 scheme can pay for the entire expense of a brand-new boiler – installation included – if you’re eligible.

What Is the Free Boiler Grant?
Free Boiler Grant is under the UK Government’s ECO4 scheme (Energy Company Obligation Phase 4). It focuses on assisting low-income families to save money on energy bills and lower carbon emissions by replacing inefficient old boiler systems.
If your boiler is more than 15 years old, faulty, or energy inefficient, and you have some eligibility requirements, you can qualify for a free boiler installation. This grant is not repayable; you don’t pay it back.
So, How Much Is the Government Boiler Grant?
The grant usually pays 100% of the expense of the new boiler and its fitting. This is worth £2,000 to £5,000 based on:
- The boiler type you require
- The energy efficiency of your home
- The rates of the installer
- Any additional work needed (such as insulation)
But if you qualify, you won’t have to pay for these costs. The installer gets paid directly via the ECO4 funding. You don’t pay anything upfront or in the future.
How Much Is the Free Boiler Grant Worth?
The cost of a new boiler installed in the UK can range from £2,500 to £5,000. If you qualify for the ECO4 scheme, all of that money could be paid for you.
Here’s what the grant may include:
| What’s Covered | Average Cost | Covered by Grant? |
| A-rated boiler (combi/system/regular) | £2,000–£3,500 | Yes |
| Installation and labour | £500–£1,000 | Yes |
| New radiators or pipework | £200–£800 | Sometimes |
| Smart controls (Hive, Nest, etc.) | £150–£300 | Sometimes |
| Home insulation upgrades | £500–£2,000 | Often |
So, the Free Boiler Grant could be worth more than £5,000, depending on what your home requires.
Who Pays for the Boiler?
The funding comes from large energy providers, such as British Gas, EDF, E.ON, and others. They are mandated under government regulations to assist customers in financial distress. The government dictates the regulations, and energy firms finance it by investing money into the program through licensed installers.
Therefore, although it is a “government grant,” the money actually comes from energy firms themselves and not from your hard-earned taxes.
Who is Eligible for the Free Boiler Scheme?
To qualify for the Free Boiler Grant, you have to satisfy three main criteria:
- You Own or Privately Rent Your Property
The scheme is for:
- Homeowners
- Private tenants (with their landlord’s agreement)
Council or housing association properties are typically covered by other schemes.
- You Have a Low EPC Rating:
Your home must be low energy efficient, and your EPC rating must be D, E, F, or G.
- You Get One of These Benefits:
You can qualify if someone living in your household gets at least one of the below:
- Pension Credit
- Universal Credit
- Income-based Jobseeker’s Allowance (JSA)
- Income-related Employment & Support Allowance (ESA)
- Income Support
- Child Tax Credit
- Working Tax Credit
- Housing Benefit
If you’re not on benefits, don’t panic, you might still qualify through something called the LA Flex scheme. This allows local councils to help low-income or vulnerable residents even if they don’t receive benefits.

Does Everyone Get the Same Amount?
No. The level of funding you get depends on the amount of carbon your house saves once it has been improved. An inefficient, poorly insulated house with an outdated boiler will probably be eligible for full funding.
In other instances, if your home does not achieve the necessary carbon savings, the grant will part-fund the cost, and you will be requested to pay a minimal top-up. This is, however, uncommon when it comes to boiler replacements because they tend to save significantly.
What Kinds of Boilers Are Covered?
The ECO4 scheme provides A-rated condensing boilers. They are extremely efficient and help you save money on bills. The boiler that you receive depends on the configuration of your home.
Typical types of boilers provided:
- Combi boilers (heat water and radiators in one appliance)
- System boilers (employ a separate hot water cylinder)
- Regular boilers (older system with water tank and cylinder)
Leading boiler brands included:
- Worcester Bosch
- Ideal
- Baxi
- Vaillant
- Viessmann
Installers will install the most appropriate boiler for your home and energy requirements.
What Goes On in the Process?
This is what normally occurs step by step:
- Apply Online or Via an Installer
You complete a quick form and submit some general information. This typically takes less than 2 minutes.
- Eligibility Check
The installer or firm verifies your benefit status, income, and type of property. They can request proof of benefits or identification.
- Home Survey
A trained surveyor comes to your property to examine the boiler, test insulation levels, and determine what improvements can be made.
- Installation
If it is approved, your boiler will be replaced at no cost. Installations are performed by skilled technicians and typically take 1–2 days.
How Long Does It Take?
From application to installation, it usually takes 2 to 4 weeks. It may be faster if you’re in urgent need (like having no heating or hot water). Some delays can happen if your home needs extra work, like insulation, before the boiler can be replaced.
What Are the Benefits?
Here’s why claiming the Free Boiler Grant is a smart move:
- £0 upfront cost
- Lower energy bills
- Warmer home
- Fewer carbon emissions
- No maintenance worries with warranty
Old boilers tend to be G-rated and waste more than 30% of energy. A brand-new A-rated boiler would save you £300–£600 annually on energy bills.
Are There Any Hidden Costs?
No. If you are eligible, the installation is completely paid for. You won’t be required to pay a penny unless additional work is required, and even that would be agreed upon beforehand.
Take care about firms charging for the survey ahead of time—make sure they are ECO4 registered.
The Bottom Line
The Free Boiler Grant under the ECO4 initiative is amongst the most worthwhile support schemes for British households in the present day. With the entire expense paid for and no additional charges, it’s a simple way to improve your heating, cut bills, and make your home more sustainable.
If your boiler’s old, faulty, or ineffective—and you receive qualifying benefits—don’t miss out. Apply now, and you might be able to have a new boiler installed without paying a thing.
