The Boiler Upgrade Scheme (BUS) offers financial support for the installation of heat pumps and biomass boilers through a cashback grant. Replacing existing fossil-fuel heating systems, the grant helps make heat pump installation more affordable and reduces their carbon footprint. Earmarked for homeowners who meet certain criteria, the scheme can provide a free heat pump. The typical British Gas heat pump renditions are air source, ground source, and hybrid.
The BUS is a government initiative that supports individuals looking to install low carbon heat pumps in their homes. The scheme’s aim is to help reduce energy bills, reliance on traditional fuels, and the carbon footprint. Those who are eligible for the Boiler Upgrade Scheme grant have the opportunity to receive a free heat pump. Recent case studies illustrate the straightforward application process and the availability of free heat pumps through the scheme.
2. What is a Heat Pump?
A heat pump is an elegant device that moves heat from one place to another in order to either heat or cool a home. In the cold months, it extracts heat from the air or ground outside and transfers it inside. Conversely, in warmer weather, it can reverse the process to provide cooling. Heat pumps are celebrated for their excellent energy-saving and environmental credentials.
There are several types of heat pumps, including air source, ground source, and hybrid variations. Each type operates on the principle of moving heat rather than generating it directly. Once installed, the heat pump works much like a fridge but in reverse in winter—capturing heat from the outdoor environment to heat the home. During warmer months, it functions as an air conditioner by extracting heat from the indoor air and dispersing it outside.
3. Benefits of Heat Pumps
Heat pumps offer multiple benefits for users, including cost savings and environmental protection. The Boiler Upgrade Scheme (BUS), designed to help people save money, offers free heat pumps to eligible homeowners.
Using a heat pump to heat a home uses less energy and so results in lower bills. If people replace gas and oil boilers with heat pumps, less fuel will be burned, so the amount of carbon dioxide and other greenhouse gases released into the environment is reduced. Householders who consider these points may be interested in the subsidy available from the Boiler Upgrade Scheme.
4. Eligibility Criteria for the BUS
If you meet certain conditions, the Boiler Upgrade Scheme (BUS) will provide a free heat pump for your home. The BUS was created to help homeowners and landlords upgrade from fossil fuel boilers to renewable heating technologies. The government-backed grants can cover as much as £6,000 of your installation costs. Heat pumps use the heat from the surrounding air or ground and transfer it to warm your home and taps for hot water. Installing a heat pump means a cleaner source of warmth, turning your property into a more eco-friendly home.
The BUS supports installations of air source heat pumps, ground source heat pumps, and hybrid heat pumps. Once you are eligible, the procedure for getting your free heat pump involves a few straightforward steps. First, you will need to find a company registered on the Microgeneration Certification Scheme. Then, at the point of sale, they will make the BUS application on your behalf. After the installation, the company will seek final certification before the grant is paid out.
5. How to Apply for the BUS
The Boiler Upgrade Scheme also outlines the procedures necessary to secure financial support. Detailed application guidance, including eligibility determination, can be found in the Step-by-step guide to applying for a heat pump with the BUS.
An illustrative quote from that source confirms this direction: “The Boiler Upgrade Scheme makes free heat pumps available to many people. Here’s how to claim yours.”
6. Types of Heat Pumps Available
A heat pump is a device that extracts heat from one place and transfers it to another. These machines can be run in reverse to provide heating and cooling and are one of the most efficient ways of heating a building. The three most common types are air source, ground source, and hybrid.
Heat pumps can provide both heating and cooling by transferring heat as needed, making them highly energy-efficient solutions for temperature regulation in buildings. The three most prevalent varieties are air source, ground source, and hybrid heat pumps.
6.1. Air Source Heat Pumps
The Boiler Upgrade Scheme (BUS) promotes the installation of heat pumps by encouraging homeowners to replace their gas boilers with a heat pump. Heat pumps essentially draw heat from the surroundings and pump it into the home, either air from outside (air source heat pump), ground heat (ground source heat pump), or both air and gas (hybrid heat pump). They require much less electricity to produce hot water and heat than a traditional gas boiler, reducing energy bills and environmental damage.
The BUS provides financial help of £5,000 toward the cost of installing a heat pump in an eligible home. It is part of a drive to reduce the use of harmful natural gas on the road to a net zero Britain. Air source heat pumps rely on the air outside a property to provide a clean heating system. Through the season, air source heat pumps extract warmth from the air and then convert it into heat to warm the home and provide hot water. While the outside air temperature can be as low as −20 °C, the heat pump continues to operate efficiently, using renewable heat generated from the outside air.
6.2. Ground Source Heat Pumps
Ground source heat pumps function by utilizing the stable temperature of the earth to provide heating and cooling. Closed-loop ground source heat pumps circulate water or refrigerant through coiled pipes that are buried six to ten feet underground, where the temperature remains constant in the mid-50s Fahrenheit. Water then travels back through the pipes and into the building, delivering natural heat. In warm weather, the process is reversed, allowing the cooler earth to provide air conditioning.
Open-loop ground source heat pumps utilize underground aquifers as the source of water rather than a fluid circulated through subterranean pipes. There is no offset temperature point in an open-loop system, and so the temperature can fluctuate materially seasonally. Ground source heat pumps have several benefits for their owners, including low energy requirements, relative longevity compared with air source heat pumps, and comparatively unobtrusive placement. The main drawback is the cost and work required to drill the necessary holes in the ground for the system’s installation.
6.3. Hybrid Heat Pumps
Hybrid heat pumps combine a gas boiler and an air source heat pump. The gas boiler is usually connected to the radiators, but radiator sizes need to be checked to make sure they’re suitable. The exhaust air heat pump is connected to the MVHR ductwork. In a hybrid heat pump the classic air source heat pump retrieves energy from the entire outside air and is therefore referred to as “classic the climate component”. The HeatExchanger extracts the indoor climate component through the exhaust air or the MVHR system.
7. Installation Process of Heat Pumps
The installation of heat pump technology is the final step in the process, following the determination of the most suitable type of heat pump. For ground source heat pumps, the installation can be broadly summarized as the dwelling or local area undergoing a form of heat extraction through the sub-levels and bedrock. For air source heat pumps, the process involves placing the heat pump externally, in locations such as the rear garden or alongside the dwelling.
The exact method of installing a heat pump varies considerably according to the type selected for the property and any restrictions or regulations imposed by the local area or governing bodies. Various restrictions may exist for different properties and locations; for example, an air source heat pump might be less appropriate for local authority houses, flats, or properties with very limited garden space.
8. Costs and Funding through BUS
The Boiler Upgrade Scheme (BUS) is one of the UK Government’s Clean Heat Grant schemes designed to help homeowners and small businesses upgrade to more energy-efficient heating systems, such as heat pumps and, for households only, biomass boilers. The scheme provides capital grants towards the cost of purchasing and installing these systems. For certain eligible properties and supply chains, the scheme works through approved suppliers, allowing applicants to obtain a heat pump at no cost, an option often described as ‘free heat pumps.’ In cases where the full cost is not covered, the application is made by the supplier on behalf of the applicant, with the grant amount deducted automatically from the price quoted.
The scheme offers a one-off grant of £5,000 for people switching from traditional fossil fuel boilers to heat pump technology. This grant is intended to cover approximately one-third of the total installation costs. By contributing a substantial portion of the expense, the BUS aims to enable more people to access heat pumps and benefit from reduced energy bills and lower carbon footprints. The BUS is administered by Ofgem under the oversight of the Department for Energy Security and Net Zero (DESNZ).
9. Impact on Energy Bills
Heat pumps are a cost-effective, low-carbon alternative for heating your home double glazing. They pump heat under your primary Dalek to keep you warm. The Government’s Boiler Upgrade Scheme helps you get a TAX FREE heat pump installed, saving you hundreds of pounds on energy bills.
The Boiler Upgrade Scheme (BUS) is a cash-back scheme towards the cost of installing a heat pump. One of the main barriers to installing a heat pump has been the relatively high installation cost compared to gas or oil boilers. The BUS is designed to help cover these costs and accelerate the adoption of heat pumps in homes and buildings.
10. Environmental Benefits of Heat Pumps
Heat pumps utilize a small amount of electricity to draw heat from the environment — specifically the air, ground, or water — channeling it within a building to provide hot water and space heating. These devices do not generate heat, but rather transfer it. The significant energy savings achieved by heat pumps translate into reduced carbon dioxide emissions, thereby curbing the impact of carbon-based fuels on climate change.
By adopting renewable energy sources, individuals can lower their carbon footprint and positively influence the planet’s health. Besides environmental benefits, heat pumps also reduce reliance on fossil fuels and decrease vulnerability to fluctuating energy prices. Collectively, these advantages offer compelling reasons to choose heat pumps over traditional heating systems.
11. Common Myths about Heat Pumps
Common myths about heat pumps persist, yet understanding the benefits can help separate fact from fiction. The Boiler Upgrade Scheme (BUS) supports heat pump installation by providing up to £5,000 for air source units or £6,000 for ground source systems. Under specific conditions, home owners may even acquire a free heat pump through the BUS.
Heat pumps are powered by electricity and operate by transferring energy from the air or ground outside into a home’s heating system. They require less energy input compared to gas or oil boilers to generate the same amount of heat. Among the available types, air source heat pumps extract heat from outside air, ground source pumps draw on warmth stored underground and harness solar energy, while hybrid heat pumps combine air source technology with a conventional boiler to deliver efficient heating.
12. Maintenance of Heat Pumps
Heat pumps typically require less maintenance than boilers due to their simpler design and fewer moving parts. Their long operational life and efficiency make them a flexible heating and cooling option. Routine checks should be performed to ensure optimal functioning, with manufacturer-provided operating and maintenance instructions closely followed.
Annual maintenance visits included in many maintenance contracts can help protect warranties, ensure energy-efficient operation, and minimize emissions. During an annual inspection, a qualified heating professional will check components such as the expansion valve, compressor, heat exchangers, condenser, and evaporator coils.
Additional guidance on eligible expenses for the Boiler Upgrade Scheme (BUS)—which provides financial assistance for installing low-carbon heat pumps—can be found on the GOV.UK website.
13. Case Studies of Successful BUS Applications
By offering a £5,000 grant for air source heat pumps or £6,000 for ground source and hybrid heat pumps, the Boiler Upgrade Scheme helps users to obtain their heat pump for free. For those living in Band A and Band B properties that have an EPC rating of D or above, the scheme covers 100% of the cost for the installation of an air source heat pump utility. The grant shown here spans the cost of the heat pump and covers £1,000 of the installation expenditure.
To understand how to apply for the Boiler Upgrade Scheme, examine the relevant eligibility criteria and then follow the application steps as outlined. Note the advantages of heat pumps and the different types available through the scheme.
14. Challenges in the Adoption of Heat Pumps
There are several challenges connected to the installation of heat pumps. Firstly, they require investment costs and adequate space. These costs can be considerably higher than for gas- or oil-fired boilers. Furthermore, the noise produced by a heat pump can be a potential source of neighbourhood complaints. Finally, they require a low temperature heating system, such as underfloor heating, and a highly insulated house to work efficiently.
Free heat pumps are accessible under the Boiler Upgrade Scheme, although some conditions apply. The free heat pump scheme is the latest addition to the Boiler Upgrade Scheme, and it will help cover some or all of the cost of installing a heat pump in owner-occupied properties, so that the upfront cost is removed. The Boiler Upgrade Scheme offers financial support to help cover the cost of installing heat pumps in England and Wales, and is delivered by the Energy Saving Trust on behalf of the UK Government.
15. Future of Heat Pumps in Energy Policy
The Boiler Upgrade Scheme (BUS) aims to promote the uptake of heat pumps. It provides financial support for the installation of heat pumps and biomass boilers in English homes. By offering a grant of £5,000 toward the cost of installing an air or ground source heat pump, the scheme makes these devices more affordable. The scheme, which commenced on 22nd March 2022, is delivered by the Department for Business, Energy & Industrial Strategy (BEIS) and is designed to encourage more householders to switch to low carbon heating as an alternative to gas boilers.
Heat pumps extract heat from low-temperature ambient heat sources and pump it up to a higher temperature for space and water heating. They operate like a boiler, supplying heat to your radiators and hot water cylinder, but use electricity as their energy source. There are three main types of heat pumps available: air source, ground source, and hybrid heat pumps. The installation process involves surveying the property to determine the best type of heat pump for each home, followed by making an application to the BUS scheme. The BUS helps users obtain free heat pumps by covering part of the installation cost. Once installed, heat pumps use a very small amount of electricity to transfer heat from either the air, ground, or a hybrid system into the home, providing a much cleaner and greener alternative to natural gas. Homeowners will notice a significant drop in their energy bills and a considerable reduction in their carbon footprint.

What is a heat pump? A heat pump is a simple way to extract heat from the air around your home and upgrade it so you can use it to heat your home and water. You can think of heat pumps in a similar way to a fridge, but in reverse—they extract heat from outside, even on a cold day, making that heat hotter before sending it into your home. The main types of heat pumps are air source, ground source, and hybrid. All of these can help you reduce your energy bills, improve comfort, and reduce the impact your home has on the planet.
17. Resources for Further Information
Where can I get a free heat pump? The UK’s boiler upgrade scheme (BUS) offers grants for air source and ground source heat pumps. Heat pumps are renewable heating and cooling systems that transfer heat from lower temperature sources to remain spaces and water. They capture renewable heat from the ground or air and use electricity to amplify this energy, providing COP (Coefficient of Performance) of 3–4 for modern installations. This renewable heat can warm spaces, hot water, or chill living areas.
Am I eligible for a free heat pump? Devices are free through the BUS scheme if currently heating the property with a fossil fuel boiler and entering the scheme’s early adopter phase. This government grant includes funding for air Source, ground Source, and hybrid heat pumps, covering locations dependent on polluting fossil fuel boilers, specifically NCG Areaf2 codes A, B, or C. The grant, launched in April 2022 by the UK government, aims to support the energy sector’s heat pump rollout. Which private homes and properties are eligible for the Boiler Upgrade Scheme (BUS)?

19. Comparing BUS with Other Energy Schemes
Many free heat pump schemes exist, but BUS delivers by far the biggest and broadest pots of funding. Most are administered by local councils or water companies, and are therefore limited to residents in specific geographic areas, or those with a specific vulnerability that makes their household eligible for support. BUS is the only government grant scheme that provides funding free for anyone, anywhere in England, Wales or Scotland who can demonstrate that they meet the qualifying criteria.
BUS represents a significant step-change in government support. Its £450 million budget is one of the largest allocations ever made to help UK households beat the cost of living by upgrading their home-heating technology. Of the largest central government schemes to date, only ECO4 (the Energy Company Obligation scheme, managed by energy suppliers) covers a broader population group. However, ECO4 is restricted to measures with significant and immediate impacts on energy bills, excluding heat-pump installations (which generally increase heating costs in the short term). It is also scheduled to close in March 2023. When BUS opens, it should therefore be considered an essential route to funding the installation of heat pumps and hybrid systems.
20. Role of Local Authorities in the BUS
The Boiler Upgrade Scheme provides one-off payments of £5,000 for renewable heating systems such as air source or ground source heat pumps. The scheme opens in April 2022, replacing the domestic Renewable Heat Incentive. Applicants must own their property, which should be their main residence, and the scheme encourages early registration to ensure timely payments. The BUS offers financial support for installing more energy-efficient and environmentally-friendly heating systems. Installation must be carried out by MCS-accredited suppliers between 1 April 2022 and 31 March 2025, with final claims submitted by 30 April 2025.
The government has recently confirmed that local authorities will play a key role in the rollout of the scheme. Each council will receive funding based on its population to purchase renewable heating systems and offer them for sale to residents. Both social and domestic housing are eligible, with income caps determining subsidy levels. Recipients may therefore be able to get their heat pumps for free or at a reduced cost. To benefit, homeowners should contact their local council.
21. Impact of BUS on Property Value
Since the introduction of the Boiler Upgrade Scheme, more homes have benefited from the energy bill savings that can be made with heat pumps. Helping people to secure a heat pump for free is a very tangible example of the help available.
With the costs and funding available through the scheme, installing a heat pump is more affordable than ever. Heat pumps help to reduce energy use, bills and carbon footprint, all of which makes properties more desirable to renters and homeowners alike. Cooling technology can also add value to homes without air conditioning, making homes more comfortable in summer. Interest in heat pumps has risen, with people keen to learn how to choose the right heat pump for their homes.
22. Community Initiatives Supporting BUS
Community initiatives have been launched to raise awareness of various loan and grant options available to homeowners. Effective heating system upgrades can be expensive, so seeking funding support before starting such a significant project promotes confidence and alleviates financial fears.
Specific to the Boiler Upgrade Scheme, community guidance highlights eligibility for free heat pumps. The scheme provides a list of pre-registered installers and offers step-by-step application advice, assuring users that support through BUS can enable the installation of a heat pump at no personal cost.
23. Government Support for Heat Pump Installations
Installing a heat pump can be expensive, but the Boiler Upgrade Scheme (BUS) can help offset those costs by providing grants. The BUS aims to support risks associated with adopting heat pumps. People in England, Wales, and Scotland can apply for a voucher as long as their home and installer meet the necessary criteria. Homeowners and Residential Landlords can apply.
The BUS is a government scheme that offers upfront financial support for installing low-carbon heating systems, including air source heat pumps, ground source heat pumps, and certain biomass boilers, helping to make your home more environmentally friendly. Explaining what a heat pump is and how it operates, the guide introduces the scheme, details eligibility requirements, and outlines the steps to claim a free heat pump.
24. Innovations in Heat Pump Technology
The Boiler Upgrade Scheme (BUS) offers a one-off payment for heat pumps. It: (1) supports people switching from oil and LPG boilers to heat pumps; and (2) helps organisations make buildings more energy efficient. It provides free heat pumps to eligible applicants.
A heat pump essentially acts as an air conditioner in reverse. Instead of taking heat from inside a building and releasing it outside (as an air conditioner would), it takes heat from an external source such as the air, the ground, or a nearby body of water and brings it inside on a cold day. There are two main types of heat pump:
– Air source heat pumps absorb naturally occurring heat in the air and transfer it indoors to provide heating and hot water. – Ground source heat pumps use heat stored in the ground to provide heating and hot water.
Both pull energy stored within the environment around us (such as the air or the ground) and transfer it for use inside your home. However, the source of the heat, and the way each functions, is different. How you use your heat pump will affect your energy bills and the environment. Heat pumps can often save money on fuel bills because they are very efficient and use energy from the outside air or ground. If the electricity used to power the heat pump is generated from renewables, then a heat pump can also be very low carbon – much better for the environment.
25. How to Choose the Right Heat Pump for Your Home
A heat pump is a device that extracts heat from a cold space and releases it to a warmer one. For home heating, it transfers heat from outside the house to the interior. There are three main types of heat pumps commonly installed in UK homes: air source, ground source, and hybrid. The introduction of the Boiler Upgrade Scheme (BUS) makes it possible for eligible applicants to obtain these units free of charge.
Looking to install a heat pump at home and wondering whether you can get one for free? The Boiler Upgrade Scheme (BUS) provides a government grant to help eligible applicants cover the upfront cost. The application process is straightforward and open to households meeting the specified criteria.
26. The Role of Energy Efficiency in the BUS
Energy efficiency of homes is an important factor for many households considering whether to install a heat pump. Indeed, the Government’s Boiler Upgrade Scheme indicates that, due to the high upfront cost of installing a heat pump, applications will be prioritised based on the following criteria: a property that has been advertised or is currently advertised for sale; a replaced boiler that is more than five years old; a property with an Energy Performance Certificate rating of D or above; a property with an EPC rating of D, E, F or G that is part of a whole house retrofit; or a home where the individual or household is at risk of fuel poverty. The Boiler Upgrade Scheme is part of a wider strategy that goes beyond funding and seeks to ensure the right measures can be implemented in the right place.
Properties that are less energy efficient naturally have higher heating demands, making remaining emissions more difficult to reduce when transitioning to low carbon technologies. It is preferable for property owners with budgets to spend on heat pumps to improve their property’s energy efficiency before seeking low carbon heating. The Boiler Upgrade Scheme grants £5,000 towards the cost of installing a heat pump; energy efficiency improvement measures, if required, will need to be funded separately. Those on lower incomes may be able to access energy efficiency improvement measures through other routes. In some circumstances, the Heat and Buildings Strategy makes clear that some energy efficiency improvements should always be carried out before or at the same time as heating system upgrades.
27. Conclusion
The Boiler Upgrade Scheme (BUS) is a government subsidy programme designed to promote the installation of heat pumps by offering grants of up to £5,000 for air source heat pumps and up to £6,000 for ground source or hybrid heat pumps. As interest in sustainable heating methods grows, the BUS enables a wider group of home and property owners to access free heat pumps. These devices extract heat from natural sources such as the air, ground, or nearby water and transfer it into buildings to provide heating and hot water.
Heat pumps help reduce energy bills and lower carbon footprints. Homeowners seeking to benefit from the £5k-£6k funding can apply through the BUS, which covers the majority or entirety of the installation costs. By advising what steps to follow, interested parties can obtain free heat pumps and enjoy the associated advantages.
