Has your boiler broken down? Considering upgrading your old, inefficient boiler for a more energy-efficient alternative? You're in luck! In 2024, there's a wealth of government grants and incentives available, offering significant funding for boiler replacements. You might even qualify for full funding under the ECO4 scheme.
These grants are more than just a handout, they're a crucial part of the UK government's pledge to achieve net-zero emissions from all UK homes by 2050. That's why they're exclusively for eco-friendly boilers. But don't worry, this is a win-win situation. Green boilers are not only better for the environment, but they're also more efficient, meaning they use less energy to keep your home cosy. By making the switch, you'll not only get help with the upfront costs but also enjoy lower energy bills, saving you a bundle in the long term.
In this comprehensive guide, we'll walk you through the array of government grants available throughout the UK and show you how to secure funding for your boiler upgrade. If you have any questions or need personalised advice, feel free to reach out. We're here to assist you every step of the way!
How to Choose the Right Boiler for Your Property
Selecting the perfect boiler for your home requires careful consideration of various factors, such as your property's size, your heating requirements, and the number of bedrooms.
Consider Your Property Size and Heating Needs

When considering your property size and heating needs, it's crucial to match them with the right boiler type. For compact spaces, a combi boiler is a top choice, offering hot water on demand without the need for a hot water cylinder or cold water tank. This makes it an excellent fit for smaller homes, ensuring efficient use of space.
On the other hand, larger homes with more than three bedrooms and higher heating requirements may benefit from a system boiler. While it does require a hot water cylinder, it eliminates the need for a cold water tank. This setup ensures an ample supply of hot water, especially advantageous for homes with multiple bathrooms or high hot water demand.
Eco-Friendly Options for Green Living

Eco-conscious individuals looking to embrace green living and cut down on their carbon footprint can explore several environmentally friendly boiler options. Electric boilers, for example, are efficient and eco-friendly, making them a great fit for homes with favourable electricity rates. Biomass boilers utilise renewable energy sources, substantially reducing carbon emissions. Additionally, condensing boilers are highly efficient, capturing and reusing heat that would otherwise be wasted. These options not only help the environment but also offer long-term savings on energy bills.

Energy Company Obligation (ECO4)
Introduced in April 2022 and scheduled to continue until 2026, the ECO4 scheme represents the fourth phase of the Energy Company Obligation (ECO) initiative.
A Whole House Approach
Taking a holistic approach, ECO4 goes beyond individual upgrades to assess your entire home. This comprehensive evaluation identifies all potential improvements, offering partial or full funding for various upgrades. These upgrades collectively reduce your carbon footprint and enhance energy efficiency. Whether it's upgrading your heating system, installing insulation, or integrating renewable energy sources, ECO4 aims to transform your home into an energy-efficient sanctuary.
Benefits of ECO4
Participating in the ECO4 scheme offers homeowners the opportunity to substantially reduce their energy bills and improve their home's comfort. This initiative prioritises support for low-income households and vulnerable individuals, providing them with substantial or full funding for their energy-efficiency measure.
Boiler Upgrade Scheme (BUS)
The Boiler Upgrade Scheme (BUS) is another significant government grant designed to support energy efficiency. Unlike the ECO4 scheme, which offers funding for multiple energy-efficiency measures, BUS provides funding for a single measure per household. This means if you have already received funding for your heating system under BUS, you will not be eligible for additional funding through this scheme.
Benefits of BUS
The BUS is exclusively available to residents of England and Wales, offering generous financial support to enhance home heating systems. Under this scheme, you can receive:
- £7,500 for Air-Source and Ground-Source Heat Pumps: These heat pumps are efficient, eco-friendly alternatives to traditional heating systems, reducing your carbon footprint and energy bills.
- £5,000 for Biomass Boilers: Biomass boilers use renewable energy sources, providing a sustainable heating solution that can significantly cut down on carbon emissions.
0% VAT
In a bid to encourage the adoption of green technologies and boost energy efficiency in homes, the UK government offers a zero VAT incentive on select energy-saving measures. This includes the installation of boilers, heat pumps, solar panels, and insulation. By reducing the VAT rate from 20% to zero on these eco-friendly upgrades, homeowners can access these improvements more affordably.
Am I Eligible for Boiler Replacement Funding?
Energy Company Obligation (ECO4): To qualify for the ECO4 scheme, you must be receiving certain benefits. These benefits include:
- Child Tax Credit
- Universal Credit
- Child Benefits
- Working Tax Credit
- Income-based Employment and Support Allowance (ESA)
- Income-based Jobseekers Allowance (JSA)
- Pension Saving Guarantee Credit
- Working Tax Credit
- Housing benefits
Don’t have any of the benefits listed above? Don't worry. You may still be eligible for a boiler replacement grant or other energy-efficient upgrades under the ECO4 Flex Scheme. This scheme is open to households with a combined income of £31,000 or below or those with a member vulnerable to cold due to a health condition.
Boiler Upgrade Scheme (BUS): Eligibility for the UK's Boiler Upgrade Scheme (BUS) is subject to specific criteria for homeowners. Here are the key points you need to know:
-
Property Ownership:
- The applicant must own the property for which the boiler upgrade is being applied.
-
Property Type:
- The scheme is available for both residential properties and small non-domestic properties.
-
Existing Heating System:
- The property should currently have an existing fossil fuel boiler (e.g., gas, oil, or coal) that will be replaced by a more efficient system.
-
Replacement System:
- The replacement system should be a renewable heating system such as a biomass boiler, air-source heat pump, or ground-source heat pump.
-
Installation by Accredited Installers:
- The new heating system must be installed by a Microgeneration Certification Scheme (MCS) accredited installer.
-
Energy Performance Certificate (EPC):
- The property must have a valid EPC with no outstanding recommendations for loft or cavity wall insulation. If such recommendations exist, they must be completed before applying for the grant.
