The free boiler scheme is a UK government-backed initiative designed to help eligible households replace old, inefficient boilers with modern, energy-efficient models—often at zero upfront cost. The scheme aims to reduce energy bills, improve home comfort, and cut carbon emissions, especially for low-income and vulnerable households.
What Is the Free Boiler Scheme?
The free boiler scheme operates under the Energy Company Obligation (ECO4), which requires major energy suppliers to fund heating upgrades for qualifying homes. If your existing boiler is inefficient, broken, or over 10 years old, you may be eligible for a fully funded replacement.
Who Is Eligible for the Free Boiler Scheme?
You may qualify for the free boiler scheme if:
You receive certain government benefits such as Universal Credit or Pension Credit
Your household income is low or you qualify under ECO Flex via your local council
Your current boiler is old, inefficient, or non-condensing
Your home has a low EPC rating (typically D, E, F, or G)
You own your home or rent privately (landlord consent required)
Eligibility can vary, so a quick assessment is usually required.
What Type of Boilers Are Available?
Under the free boiler scheme, eligible households may receive:
A-rated energy-efficient gas boilers
Boiler controls and smart thermostats
Heating system upgrades to improve efficiency
In some cases, low-carbon alternatives such as air source heat pumps may also be recommended, depending on the property.
Benefits of the Free Boiler Scheme
Upgrading your boiler through the free boiler scheme offers multiple advantages:
Reduced energy bills due to higher efficiency
Improved heating reliability and comfort
Lower carbon emissions
No or minimal installation costs
Increased home value and EPC rating
How to Apply for the Free Boiler Scheme
The application process is simple and usually handled by an approved installer:
Check your eligibility online or through a registered ECO provider
Book a free home assessment
Receive confirmation of funding approval
Have your new boiler installed by certified engineers
Most installations are completed quickly with minimal disruption.
Free Boiler Scheme vs. Boiler Upgrade Scheme
While the free boiler scheme focuses on gas boiler replacements for eligible households, the Boiler Upgrade Scheme (BUS) supports low-carbon heating systems like heat pumps and may involve homeowner contributions. Your installer can advise which option is best for your home.
Final Thoughts
The free boiler scheme is a valuable opportunity for households struggling with high heating costs or unreliable boilers. If you meet the eligibility criteria, you could enjoy a warmer home, lower bills, and peace of mind—without the financial burden of replacing your boiler.
