10 Essential Tips for Gas Boiler Grants in the UK
If you are a UK homeowner looking to replace your old gas boiler with a more energy-efficient and cost-effective option, you might be eligible for a gas boiler grant through various government schemes. Here are 10 essential tips to help you navigate these programs and make the most of the available grants.
Understanding the Boiler Upgrade Scheme (BUS)
The Boiler Upgrade Scheme (BUS) is a key initiative aimed at supporting the transition to low-carbon heating systems. Launched in April 2022, the scheme provides upfront capital grants for the installation of heat pumps and other low-carbon technologies in England and Wales[2][4].
💡 Key Takeaway
The BUS has been extended until 2028, with an additional £55 million in funding for the 2024/25 year and £295 million for the 2025/26 year[2).
Eligibility Criteria
To qualify for the BUS, you need to meet certain criteria. Here are the key points:
- Property Type: The scheme applies to domestic and non-domestic buildings in England and Wales.
- Insulation Requirements: As of May 2024, the requirement to have no outstanding recommendations for loft and cavity wall insulation on the property's EPC certificate has been removed[2).
- Commissioning Dates: Applications are not eligible if the system was commissioned more than 120 days before the application date[2).
Available Grants and Costs
The grant levels under the BUS have been adjusted to encourage greater uptake of low-carbon heat systems:
Boiler Type | Grant Amount |
---|---|
Air Source Heat Pumps (ASHPs) | £7,500 (increased from £5,000 as of October 2023) |
Ground Source Heat Pumps (GSHPs) | £7,500 (increased from £6,000 as of October 2023) |
Biomass Boilers | £5,000 |
Step-by-Step Process to Apply
- Check Eligibility: Determine if your property meets the eligibility criteria by reviewing the scheme's guidelines and your property's Energy Performance Certificate (EPC)[2][4>.
- Gather Documents: Prepare all necessary documents, including proof of ownership, EPC certificate, and any other required paperwork.
- Find a Certified Installer: Ensure that your installer is certified under the Microgeneration Certification Scheme (MCS) to qualify for the grant.
- Apply Online: Submit your application through the official BUS portal. You will need to provide details of your property and the chosen heating system.
- Receive and Redeem Voucher: Once your application is approved, you will receive a voucher that you can redeem with your certified installer.
Benefits of the Boiler Upgrade Scheme
The BUS offers several benefits to homeowners:
- Cost Savings: Significant grants to offset the installation costs of low-carbon heating systems.
- Energy Efficiency: Transition to more energy-efficient heating systems, reducing your energy bills and carbon footprint.
- Government Support: Financial support from the government to help you upgrade to a more sustainable heating solution.
🔧 Expert Tip
Consider delaying your application if there are upcoming changes to grant levels or scheme eligibility. For example, the grant increase in October 2023 led to a surge in applications, so timing your application strategically can be beneficial[5).
ECO4 Scheme: Another Option for Free Boiler Replacements
In addition to the BUS, the ECO4 scheme is another government initiative aimed at helping low-income households and vulnerable individuals replace their old boilers with new, energy-efficient ones. Here’s how it works:
- Eligibility: You must be receiving certain government benefits and meet specific criteria related to your property and income.
- Free Boiler Replacement: Eligible households can receive a free boiler replacement, which can significantly reduce their energy bills and improve their home's energy efficiency.
- Application Process: You typically need to apply through a certified installer who will assess your eligibility and handle the application process.
💡 Key Takeaway
The ECO4 scheme is particularly beneficial for those who may not qualify for the BUS but still need to upgrade their heating systems[5).
Regional Uptake and Statistics
The uptake of the BUS varies across different regions in England and Wales. Here are some key statistics:
- Regional Breakdown: The South East of England has seen the highest number of installations, with 7,917 installations, while the North East has seen the fewest, with just 1,107 installations[5).
- Grant Payments: To date, 39,786 grants have been paid through the scheme, with the majority going to homes replacing gas boiler systems (51%) and oil heating systems (19%)[5).
