Understanding the ECO4 Boiler Grants
The ECO4 scheme is a government-backed initiative designed to improve heating efficiency for low-income households and vulnerable individuals. Here’s what you need to know:
💡 Key Takeaway
The ECO4 scheme focuses on helping those who struggle with heating costs by providing financial assistance for boiler replacements and additional energy-saving measures.
Who is Eligible for ECO4 Boiler Grants?
- Income and Benefits: Applicants must receive certain benefits (e.g., Pension Credit, Universal Credit) or live in a low-income household.
- Vulnerable Individuals: The elderly or those with disabilities may also be eligible.
- Property Ownership: Applicants must own their property or have the landlord’s consent if they are tenants.
What Does the ECO4 Grant Cover?
- Boiler Replacement: The grant can cover the full or partial cost of replacing an old boiler with a more energy-efficient model.
- Additional Measures: Support for insulation and draught-proofing to reduce overall heating bills.
🔧 Expert Tip
Ensure you meet all eligibility criteria before applying, as the specific coverage depends on your eligibility and the energy supplier you work with.
Understanding the Boiler Upgrade Scheme (BUS)
The Boiler Upgrade Scheme (BUS) is another key initiative aimed at decarbonising heat in buildings by encouraging the installation of heat pumps and biomass boilers.
💡 Key Takeaway
The BUS offers upfront capital grants to support the installation of low-carbon heating systems in homes and non-domestic buildings in England and Wales.
Who is Eligible for the Boiler Upgrade Scheme?
- Location: Homeowners in England and Wales are eligible.
- Property Type: Properties owned by companies are also eligible if they are residential.
- EPC Requirement: A valid Energy Performance Certificate (EPC) is required, but from 8th May 2024, loft or cavity wall insulation is no longer a prerequisite[5].
What Does the Boiler Upgrade Scheme Offer?
- Grants for Heat Pumps: Up to £7,500 for air source heat pumps (ASHPs) and ground source heat pumps (GSHPs)[4].
- Grants for Biomass Boilers: Up to £5,000 for biomass boilers.

Frequently Asked Questions (FAQs)
Will I Have to Replace My Gas Boiler After 2025?
No, you will not be required to replace your existing gas boiler with a low-carbon alternative. However, from 2025, new build homes must install low-carbon heating systems instead of gas boilers as part of the UK’s plan to cut carbon emissions[5].
Can I Get a Grant to Replace My Old Boiler Through Both Schemes?
No, you can only apply for a grant through one of the schemes. The ECO4 scheme is generally for low-income households and vulnerable individuals, while the Boiler Upgrade Scheme is open to all homeowners in England and Wales who are replacing fossil fuel heating systems[2][5].
How Long Do the Grants Last?
The grants under both schemes are subject to availability and specific terms. It is important to apply as soon as possible to ensure you do not miss out on the available funding[4].
Key Points to Remember:
- ECO4 Scheme: Focuses on low-income households and vulnerable individuals, offering full or partial cost coverage for boiler replacements and additional energy-saving measures.
- Boiler Upgrade Scheme (BUS): Offers upfront capital grants for heat pumps and biomass boilers, targeting homeowners in England and Wales.
- Eligibility and Application: Ensure you meet the specific eligibility criteria for each scheme and follow the step-by-step application process.
- Benefits: Both schemes offer significant cost savings, improved energy efficiency, and environmental benefits.
By understanding the details and benefits of these government schemes, you can make an informed decision about which boiler grant is best for you and take the first step towards a more energy-efficient and cost-effective heating solution.
