The Boiler Upgrade Scheme:
Making Heat Pumps Affordable in England & Wales
Get £7,500 Towards Your Upgrade via the Boiler Upgrade Scheme Grant
If you’re considering a transition to low-carbon heating, the UK Government’s Boiler Upgrade Scheme (BUS) provides up to £7,500 towards the installation of an air source to significantly reducing the upfront cost of upgrading your home.
The scheme is designed to accelerate the move away from fossil fuel heating, supporting homeowners who want to improve efficiency, lower long-term running costs, and reduce carbon emissions without compromising comfort.
At Adlår Castra UK, we manage the process on your behalf. From confirming eligibility and handling the application to system design and installation, everything is delivered through one experienced in-house team. There is no administrative burden placed on you and no uncertainty about what comes next.
The result is simple: a professionally engineered heat pump system, supported by government funding, installed with clarity and confidence.
What Is the Boiler Upgrade Scheme?
The Boiler Upgrade Scheme (BUS) is one of the UK’s most substantial government incentives for renewable heating. Available to homeowners in England and Wales, it was introduced in April 2022 as part of the government’s long-term strategy to achieve Net Zero carbon emissions by 2050.
The scheme provides direct, upfront capital grants to support the replacement of fossil fuel heating systems including gas, oil, and LPG boilers with low-carbon alternatives such as air source and ground source heat pumps.
Rather than relying on tax rebates or complex reimbursement models, the BUS reduces the installation cost at source. This immediate financial support lowers the barrier to entry, enabling homeowners to transition to cleaner, more efficient heating with greater confidence and clarity.
In practical terms, it transforms heat pumps from a long-term aspiration into a financially viable upgrade today.
What Does the Boiler Upgrade Scheme Offer?
If you’re eligible, the BUS provides a one-time grant per property for the following heating system installations:
£7,500 for an air source heat pump
£7,500 for a ground source heat pump
£5,000 for a biomass boiler
*Grants are not available for hybrid systems or properties that already have a low-carbon heating system.
How the BUS Makes Heat Pumps More Affordable
1. Reduces Upfront Installation Costs
Heat pumps can cost more than traditional boilers to install. The BUS grant cuts this initial cost by up to £7,500 — a significant reduction that puts eco-friendly heating within reach.
2. Improves Long-Term Value
Heat pumps use renewable energy to heat your home and hot water, offering potential energy bill savings of up to 40% when compared to electric or oil heating systems.
3. Helps You Become More Energy Independent
By switching from fossil fuels, you reduce your exposure to volatile gas and oil prices — something many UK households struggled with during the recent energy crisis.
4. Boosts Property Value
Installing a heat pump can increase your home’s Energy Performance Certificate (EPC) rating and raise your property’s value by up to 3%, making it more attractive to future buyers.
How the Boiler Upgrade Scheme Makes Heat Pumps More Affordable
Installation day is where everything comes together. Our in-house team of qualified engineers arrive fully prepared to install your new heating system efficiently and respectfully.
You can rest assured that your air source heat pump installation will be as quick and smooth as possible, since we prioritise minimal disruption while also maintaining the highest standards of quality and safety.
Here’s what to expect when we install an air source heat pump:
While heat pumps require a higher initial investment than traditional boilers, the Boiler Upgrade Scheme provides up to £7,500 in direct government funding.
This grant is applied at the point of installation, significantly lowering the capital cost and making a professionally engineered renewable system far more accessible.
Heat pumps harness renewable energy from the air, delivering highly efficient, low-temperature heating. When correctly designed and optimised, they can reduce running costs particularly when replacing electric resistance or oil-based systems while providing stable, predictable performance over time.
The result is not simply lower bills, but improved lifetime value.
By moving away from gas, oil, or LPG, homeowners reduce their reliance on volatile global fuel markets. Recent energy price fluctuations have demonstrated how vulnerable conventional heating systems can be to external pressures.
Low-carbon heating offers greater resilience and long-term cost stability.
Installing a heat pump can improve your home’s Energy Performance Certificate (EPC) rating and overall environmental credentials. Increasingly, energy efficiency is a priority for buyers and a well-specified renewable system can strengthen both marketability and long-term property value.
In short, the Boiler Upgrade Scheme doesn’t simply reduce installation costs, it improves the financial case for upgrading altogether.
