Switching to a heat pump is one of the most effective ways to cut energy costs, reduce carbon emissions, and future-proof your home’s heating. However, the upfront cost of installation can be a deterrent for many homeowners. 

Fortunately, the Boiler Upgrade Scheme (BUS) offers a £7,500 grant towards the cost of an air source heat pump, helping to make the transition to eco-friendly heating more affordable.

At Adlår Castra UK, we specialise in high-efficiency dual heat pump systems and provide full support with the BUS grant application process. Our team ensures a smooth and hassle-free experience, making it easier than ever to upgrade your home’s heating system. 

In this guide, we’ll explain how the Boiler Upgrade Scheme works, who is eligible, how much you can save, and how to apply in just a few simple steps.

What Is the Boiler Upgrade Scheme?

The Boiler Upgrade Scheme is a UK government initiative designed to encourage the transition to renewable heating in homes and business properties across England and Wales.

Traditional fossil fuel heating systems contribute significantly to climate change, prompting many homeowners to seek greener alternatives. However, the upfront cost of switching can be a major barrier. By offering a grant of up to £7,500, the BUS makes air source heat pumps and other low-carbon heating solutions more financially viable. 

This is part of the UK’s broader strategy to cut carbon emissions and achieve net zero by 2050. With heating accounting for a large portion of household energy consumption, replacing old boilers with highly efficient heat pumps is a crucial step toward a greener future. 

Not only does this initiative support homeowners financially, but it also contributes to energy security by reducing reliance on imported fossil fuels and mitigating the impact of fluctuating gas prices.

The Boiler Upgrade Scheme is only available until 2028, so homeowners should act early to secure funding before it is depleted or the grant expires. 

Who Is Eligible for the BUS Grant?

Currently, the Boiler Upgrade Scheme is only open to people in England and Wales, though there are possible alternatives for those living in Scotland or Northern Ireland.

You must also meet the following criteria to qualify for the BUS grant:

• You must own the property – The scheme is only available to property owners. The property in question can be a home, second home, private rental property, or business.
• You must be replacing a fossil fuel heating system – Systems eligible to be replaced include gas, oil, or LPG boilers and direct electric heating.
• Your property must have a valid EPC – An Energy Performance Certificate (EPC), which is valid for 10 years, tells you how energy efficient a property is. You can check the status of yours here.
• Your heat pump must be installed by an MCS-accredited company – Adlår Castra UK is fully MCS certified, ensuring compliance with BUS requirements.

Funding from the scheme is also not available for new-build homes (unless they are self-builds) or for homes that already have a heat pump installed.

However, homes that have already had funding to improve energy efficiency, for example through the Great British Insulation Scheme, are still eligible for the BUS grant.

How Much Can You Save with the BUS Grant?

£7,500 Off the Initial Cost of a Heat Pump

The Boiler Upgrade Scheme covers £7,500 of the total cost of installing an air source, ground source, or water source heat pump. This significantly reduces the upfront expense for homeowners, making renewable heating more accessible.

Among the available options, air source heat pumps have become increasingly popular, with sales and installations rising rapidly over the last 5 years.

Long-Term Energy Bill Savings

Beyond the BUS grant savings, heat pumps can offer long-term financial benefits by lowering your energy bills. 

Heat pumps can achieve efficiency levels of up to 400%, producing four times more heat per unit of electricity compared to a standard gas boiler.

This results in lower heating costs (particularly in well-insulated homes) and more stable energy bills, as heat pumps rely on electricity instead of volatile gas prices.
