What Is the Free Boiler Scheme?
The Free Boiler Scheme is a government-backed program designed to help low-income families and vulnerable households upgrade to more energy-efficient heating systems.
Old boilers waste a lot of energy, increasing heating costs and carbon emissions. By replacing them with modern, energy-efficient boilers, households can save money on energy bills and reduce their environmental impact.
The scheme is part of the ECO program, which requires large energy companies to support households in improving energy efficiency. If you qualify, you could get a new A-rated boiler installed for free or at a reduced cost.
Who Qualifies for a Free Boiler?
To qualify for the Free Boiler Scheme, you need to meet specific criteria. Eligibility is mainly based on income, benefits received, and the condition of your current boiler.
1. You Must Be a Homeowner or a Private Tenant
The scheme is available to homeowners and private tenants. Social housing tenants usually do not qualify since housing associations have their own energy efficiency programs. If you rent your home from a private landlord, you will need their permission before applying.
2. You Must Receive Certain Benefits
To qualify, you or someone in your household must be receiving one of the following government benefits:
- Pension Credit (Guaranteed Credit or Savings Credit)
- Universal Credit
- Income Support
- Income-based Jobseeker’s Allowance (JSA)
- Income-related Employment and Support Allowance (ESA)
- Working Tax Credit
- Child Tax Credit
- Housing Benefit
- Child Benefit (depending on income and household size)
Each benefit has its own income thresholds, which determine whether you qualify. For instance, Child Benefit eligibility depends on the number of children in the household and total income.
3. Your Boiler Must Be Old and Inefficient
The scheme mainly targets households with inefficient, non-condensing boilers that are at least 10 years old. These boilers are expensive to run and contribute to high energy bills. If your boiler is relatively new or still functioning efficiently, you may not qualify.
How to Apply for the Free Boiler Scheme
If you meet the eligibility criteria, the application process is straightforward. Here’s what you need to do:
Step 1: Check Your Eligibility
The first step is to check if you qualify. Many websites offer free eligibility checks, where you can enter details about your income, benefits, and boiler condition. You can also contact an ECO-approved installer directly.
Step 2: Choose an Approved Installer
Only certified installers registered with the ECO scheme can provide free boiler replacements. If you pass the eligibility check, you will be referred to an approved installer in your area.
Step 3: Home Assessment
An assessor will visit your home to inspect your current boiler and heating system. They will confirm if you qualify and recommend the best boiler replacement for your needs.
Step 4: Boiler Installation
If your application is approved, a qualified engineer will install the new boiler. In most cases, installation takes only one day. The installer will remove the old boiler and replace it with a new energy-efficient model.
Benefits of the Free Boiler Scheme
The Free Boiler Scheme offers several benefits, including:
Lower Energy Bills
Modern A-rated boilers use less energy, which can significantly reduce heating costs. Many households save hundreds of pounds per year on energy bills.
Reduced Carbon Emissions
New boilers are more efficient and environmentally friendly. By reducing energy waste, the scheme helps lower the UK’s carbon footprint.
Improved Home Comfort
An energy-efficient boiler provides consistent heating and hot water, making homes warmer and more comfortable.
No Upfront Costs
For those who qualify, the scheme covers the full cost of the boiler and installation, so there are no upfront expenses.
Common Reasons Applications Are Rejected
Not all applicants are successful. Here are some common reasons why applications may be rejected:
You Don’t Receive the Right Benefits
If you do not receive any of the qualifying benefits, you may not be eligible. However, some energy providers offer separate funding options, so it is worth checking.
Your Boiler Is Too New
The scheme is designed to replace old, inefficient boilers. If your boiler is less than 10 years old, it may not qualify for a free replacement.
Your Home Is Not Suitable
Some homes may not be eligible due to their heating system setup. If your home does not support a standard gas boiler installation, the scheme may not apply.
What If You Do Not Qualify?
If you do not meet the eligibility criteria, there are still other ways to upgrade your heating system affordably.
Government Grants and Schemes
The UK government runs several other energy efficiency programs, such as the Green Homes Grant or the Warm Home Discount, which may help with heating costs.
Energy Supplier Schemes
Some energy companies offer discounts or low-cost financing for boiler replacements. Contact your provider to check if they have any assistance programs.
Boiler Finance Plans
Many boiler installers offer financing options, allowing you to spread the cost over several months or years. While this is not free, it can make upgrading to a more efficient boiler more affordable.
Final Thoughts
The UK’s Free Boiler Scheme is a fantastic opportunity for households to upgrade to an energy-efficient heating system without the high cost. If you receive qualifying benefits and have an old or inefficient boiler, you may be eligible for a free replacement.
To apply, you’ll need key documents — such as proof of homeownership or tenancy, income or benefits, boiler condition, identity, and energy performance. Renters must also provide landlord approval.
Gathering these documents early will make the application process simple and smooth. Typically, approval takes just 2–3 days, depending on the installer and your eligibility.
While the eco5 scheme is expected to launch in 2026, current support under ECO4 offers full boiler replacements for eligible households right now.
Apply through an approved installer today to check your eligibility and start saving on your energy bills — all while keeping your home warmer and more eco-friendly.
