Boiler Upgrade Grants Given Additional Funding

Updated October 2026

Thinking about replacing your old gas or oil boiler with a more energy-efficient heating system? The government's Boiler Upgrade Scheme (BUS) could make switching to an air source heat pump significantly more affordable, with grants of £7,500 available for eligible installations and up to £9,000 for qualifying off-gas-grid properties.

With additional government funding supporting the scheme, homeowners across England and Wales have an opportunity to reduce the upfront cost of moving to low-carbon heating.

At Ecosolv Renewables, we help homeowners in Frome, Bath, Wiltshire and the surrounding areas choose suitable air source heat pump systems, understand their grant eligibility and access available funding. Better still, we handle the Boiler Upgrade Scheme application on your behalf, making the process straightforward from start to finish.

What Is the Boiler Upgrade Scheme?

The Boiler Upgrade Scheme is a government-funded initiative designed to help homeowners and property owners replace traditional fossil fuel heating systems with more energy-efficient, low-carbon alternatives.

The scheme provides an upfront grant towards the installation of an eligible heat pump or biomass boiler, helping to reduce one of the biggest barriers to switching to renewable heating: the initial installation cost.

The current grant amounts include:

• £7,500 towards an air-to-water source heat pump, which uses energy from the outside air to heat your home and hot water.
• £7,500 towards a ground source heat pump, which extracts heat from the ground.
• £9,000 towards an eligible air-to-water or ground source heat pump for certain off-gas-grid properties replacing oil or LPG heating, available until 31 March 2027.
• £2,500 towards an eligible air-to-air heat pump.
• £5,000 towards an eligible biomass boiler.

For most homeowners considering an air source heat pump, the £7,500 grant can make a substantial difference to the overall cost.

Importantly, the funding is a grant, not a loan, so it does not need to be repaid when the scheme's conditions are met.

Rather than receiving the money directly, the grant is deducted from your installation cost by your approved installer.

Who Qualifies for the Boiler Upgrade Scheme?

One of the main advantages of the Boiler Upgrade Scheme is that eligibility is not based on household income. This means you do not have to receive benefits or fall below a particular income threshold to apply.

To qualify, you will generally need to meet the following conditions:

• Own the property: The scheme is open to eligible property owners, including homeowners, landlords and owners of second homes.
• Have a property in England or Wales: The BUS grant is available for qualifying installations in these two countries.
• Replace an existing heating system: Eligible systems include gas, oil, LPG and conventional electric heating systems.
• Install an eligible low-carbon heating system: Your new heat pump must meet the scheme's technical requirements.
• Use an MCS-certified installer: The application must be submitted by a suitably certified installer.

Most existing privately owned homes can be considered for the scheme, although social housing, most new-build properties and properties that have previously received certain government grants for low-carbon heating are generally excluded.

Do You Need an EPC or New Insulation to Qualify?

The Boiler Upgrade Scheme has become more accessible following changes to its eligibility rules.

Since 28 April 2026, a valid Energy Performance Certificate (EPC) is no longer a mandatory requirement for applying. Where a valid EPC already exists, its details will still need to be provided.

Likewise, having recommendations for loft or cavity wall insulation does not automatically prevent you from receiving a grant.

However, a well-insulated property can help your heat pump operate more efficiently and keep your home comfortable throughout the year.

At Ecosolv Renewables, we assess your property's heating requirements and explain any improvements that may help you get the best performance from your new system.

How Does Ecosolv Renewables Help with Your Grant Application?

Applying for government funding might sound complicated, but the Boiler Upgrade Scheme is designed to be managed by your heating installer.

As an MCS-certified heat pump installer based in Frome, Ecosolv Renewables helps take the hassle out of the application process.

Here's how we help:

1. Initial consultation and eligibility check: We discuss your existing heating system, property requirements and potential eligibility for BUS funding.
2. Heat pump assessment and quotation: We help identify a suitable heating solution and provide a quotation showing the applicable grant deduction.
3. Grant application: We submit the Boiler Upgrade Scheme application to Ofgem on your behalf and help you understand any information or confirmation required.
4. Professional installation: Once the necessary arrangements are in place, our experienced team installs and commissions your new heat pump system.
5. Grant deduction: The approved grant is deducted from the eligible installation cost, so you pay the remaining balance rather than having to reclaim the funding yourself.

You remain involved in confirming your consent and eligibility, but we manage the application and associated paperwork for you.

What Does This Mean for Homes in Frome, Bath and Wiltshire?

For homeowners across Frome, Bath and Wiltshire, the Boiler Upgrade Scheme presents a valuable opportunity to upgrade older heating systems while reducing upfront installation costs.

Properties across the region vary considerably, from period cottages and traditional terraced homes to modern detached houses and rural properties that are not connected to the mains gas network.

This is why choosing the right heating system for your individual property is so important.

In Frome and surrounding Somerset villages, homeowners looking to replace ageing gas or oil boilers may be able to access significant financial support towards an air source heat pump.

In Bath, where many properties have distinctive architectural features or older heating systems, a properly designed heat pump installation can provide an efficient alternative to conventional heating. Listed buildings and properties in conservation areas may require additional consideration.

Across Wiltshire, particularly in rural locations where homes rely on oil or LPG, qualifying homeowners could benefit from the increased £9,000 grant available until 31 March 2027.

For properties in towns such as Trowbridge, Westbury, Bradford-on-Avon, Warminster and Melksham, the standard £7,500 grant could also help make upgrading to low-carbon heating more accessible.

Of course, every home is different. Property insulation, radiator sizes, heat loss and the existing heating system all play an important role in determining the most suitable solution.

That's where local expertise makes a difference.

Ecosolv Renewables works with homeowners throughout the region, providing tailored advice and professional installation services to help you make an informed decision.

Are Air Source Heat Pumps Worth Considering?

An air source heat pump extracts heat from the outside air and uses electricity to provide heating and hot water for your home.

Unlike traditional boilers, which generate heat by burning fuel, a heat pump transfers naturally occurring heat from one place to another.

This makes heat pumps highly efficient, with a well-designed system capable of delivering several units of heat for every unit of electricity consumed.

Benefits can include:

• Lower-carbon heating: Reduce your home's reliance on fossil fuels.
• High energy efficiency: A properly designed heat pump can deliver more useful heat per unit of electricity than a conventional electric heating system.
• Comfortable, consistent warmth: Heat pumps are designed to provide steady heating throughout your home.
• Long-term heating solution: Modern systems can provide reliable heating for many years when professionally installed and maintained.
• Government financial support: Reduce the initial cost of installation with an eligible BUS grant.

Actual running costs and savings will depend on your property's heating demand, energy tariffs, existing system and how your heat pump is designed and operated.
