Air Source Heat Pumps: Boiler Upgrade Scheme (BUS)
As the UK accelerates its transition to low-carbon heating, financial support is available to help homeowners upgrade from traditional boilers to cleaner alternatives. The Boiler Upgrade Scheme offers upfront grants towards the cost of installing a heat pump.

At Eljay Energy, we specialise in renewable energy solutions, including air source heat pump installations. In this blog, we’ll explore funding to support with installation.
Boiler Upgrade Scheme: Making Heat Pumps More Affordable
As the UK continues its transition to cleaner, greener heating, the Boiler Upgrade Scheme (BUS) is helping homeowners and small business owners make the switch from fossil fuel heating to low-carbon options. If you’re thinking about replacing your old gas or oil boiler with an air source heat pump, this scheme could make that decision easier and more affordable.
What Is the Boiler Upgrade Scheme?
The Boiler Upgrade Scheme is a UK Government grant that provides up-front financial support for the installation of low-carbon heating systems such as air source and ground source heat pumps. Instead of paying the full cost yourself and waiting for reimbursement, the grant is taken off the price you pay to your installer.
How Much Funding Can You Get?
Under the BUS:
• £7,500 towards an air source heat pump (ASHP)
• £7,500 towards a ground source heat pump (GSHP)
• £5,000 towards a biomass boiler (in specific rural cases)
This support significantly reduces the upfront cost of low-carbon heating technology and brings these systems closer in cost to traditional boilers.
Who Can Apply?
You could be eligible for the BUS if:
✔ You own the property you want to upgrade
✔ You’re replacing an existing fossil fuel heating system (e.g., gas, oil, LPG)
✔ Your property has a valid Energy Performance Certificate (EPC)
✔ Your installer is certified under the Microgeneration Certification Scheme (MCS) and applies for the grant on your behalf
The scheme currently covers homes and small non-domestic buildings in England and Wales.
How It Works - Simple and Installer Led
The Boiler Upgrade Scheme is installer-led, meaning your chosen MCS-certified installer will handle the grant application through Ofgem. You simply choose your system and installer, agree a quote, and the grant amount is deducted from the price you pay. At Eljay Energy we are an MSC- certified installer and would be happy for you to get in touch for us to provide a no obligation quote.
In most cases:
1. Contact an MCS-certified installer for a quote
2. Receive confirmation of eligibility
3. Installer applies for the grant on your behalf
4. Grant is deducted from the installation price
There’s no application form you need to send to the Government, your installer takes care of it.
Why This Matters
Heat pumps are highly efficient, extracting heat from the air or ground and using electricity to provide heating and hot water. They can deliver substantial energy bill savings and help reduce household carbon emissions over time. But, their upfront cost can be a barrier for many homeowners.
The Boiler Upgrade Scheme helps bridge that cost gap, making the switch to renewable heating more accessible and attractive than ever before.

Customer Feedback
“I hardly ever write reviews about companies, but this time I felt compelled to because I am so impressed with this company.
We had our electric heating replaced with a heat pump system in our house. They installed a Daikin system for us. The team worked quickly and kept everything very clean. They covered all areas with protective film where they needed to walk during the work. During the few days when we were without heating due to the installation, the weather was very cold (November), and they brought us electric heaters to keep us warm.
They only replaced four radiators but checked all of them thoroughly at the end of the work. One of the radiators was leaking slightly, and they fixed it free of charge. They even relabeled the fuse box for us. They committed to a shorter timeline than other companies we contacted, and they delivered on their promise. Their pricing was also among the most competitive.
Overall, I can’t think of a single thing I wasn’t satisfied with. Thank you so much for your excellent work, Eljay Energy!” Zoltan Nagy, A Happy Customer.
