Can Your Home Qualify For The Boiler Upgrade Scheme?

The Boiler Upgrade Scheme (BUS) can reduce the cost of installing an eligible low-carbon heating system, but not every UK property qualifies. The scheme is currently available in England and Wales and has specific rules covering property ownership, existing heating, the type of building and the proposed replacement system.

For homeowners, the important question is not simply whether the property has an old boiler. Several conditions need to be met before a grant can be awarded.

Here is how to assess whether your home could qualify.

Is Your Property In England Or Wales?

If you are wondering Who Qualifies for the Boiler Upgrade Scheme, the first requirement is location.

BUS is available for eligible properties in England and Wales. Scotland and Northern Ireland have separate heating support arrangements, so a property in either of those countries cannot use the Boiler Upgrade Scheme.

If you own properties in different parts of the UK, eligibility needs to be considered separately for each one.

Do You Own The Property?

You generally need to own the property where the new heating system will be installed.

BUS can cover more than owner-occupied homes. Eligible applicants can include people who own:

• Their main residence
• A second home
• A property they rent to tenants
• Certain non-residential properties

The scheme therefore isn't limited to homeowners who live in the property themselves. However, the building must satisfy the relevant BUS conditions.

What Heating System Does Your Home Have?

Your existing heating system is one of the most important parts of the eligibility assessment.

BUS is designed to help replace existing fossil fuel or certain electric heating systems with an eligible low-carbon alternative. This can include heating systems using:

• Gas
• Oil
• LPG
• Electricity

The replacement system must meet the scheme's requirements. You cannot normally use BUS to replace an existing low-carbon heating system, such as a heat pump, with another heat pump.

A homeowner who already has a heat pump therefore cannot simply use the scheme to subsidise an upgrade to a newer model.

Which Heating Systems Can BUS Support?

The scheme supports specific technologies rather than every type of heating upgrade.

Current grant categories include:

There is also an enhanced grant of up to £9,000 for qualifying air-to-water and ground source heat pumps installed in eligible off-gas-grid properties where oil or LPG heating is being replaced. This higher grant is available until 31 March 2027.

The grant amount therefore depends on both the technology and, in some cases, the property's existing heating arrangement.

Could An Off-Gas-Grid Home Receive More?

Possibly. If your property is not connected to the gas grid and currently uses oil or LPG for heating, you may qualify for the higher £9,000 contribution towards an air-to-water or ground source heat pump.

There are specific rules for establishing whether a property is genuinely off the gas grid. For example, a property with a capped or clamped gas meter can still be treated as having a mains gas connection under BUS rules.

The property must also meet other conditions for the uplift, so simply living in a rural area does not automatically qualify you for £9,000.

Is A New-Build Home Eligible?

Most new-build properties do not qualify for BUS. There are, however, circumstances where a self-build property can qualify. The rules are designed to distinguish qualifying self-build homes from standard new-build developments.

A completed new-build property that has already been fitted with a fossil fuel heating system may also be eligible in certain circumstances.

If you are unsure whether your property counts as a self-build or new build under the scheme, it is better to have the installer check the position rather than assume it qualifies.

What About Social Housing?

Social housing is excluded from BUS.

This is an important distinction because other types of rented property can potentially qualify. A privately owned rental property may be eligible, provided it meets the other scheme conditions.

Therefore, being a rental property does not automatically make a home ineligible. The ownership and housing category need to be considered together.

Does Your Home Need An EPC?

An Energy Performance Certificate can form part of the application process.

For retrofit installations, the installer generally provides a valid EPC number when submitting the BUS application. Where a property does not have a valid EPC, alternative evidence may be accepted in accordance with the scheme rules.

Having an EPC does not, by itself, guarantee eligibility. It is one piece of information used when assessing the property.

Does Your Home Need To Be Well Insulated?

There is a common misconception that every home must have extensive insulation upgrades before it can receive BUS funding.

That is not the basic eligibility rule. Previous funding for energy-efficiency measures such as insulation does not automatically prevent you from receiving BUS support.

That said, insulation still matters when considering whether a heat pump is appropriate.

A heat pump generally works most effectively when the home's heat loss has been properly assessed and the system is designed around the building's actual requirements. An installer may therefore recommend improvements or explain how the existing insulation affects the proposed system.

The distinction is important: insulation and BUS eligibility are not the same question.

Has Your Home Already Received Government Funding?

Previous funding can affect eligibility, but it depends on what the funding paid for.

A property cannot normally receive BUS funding for a heat pump or biomass boiler where government funding has already been provided towards the purchase or installation of that same low-carbon heating system. Funding through ECO for the same heating installation can also create an exclusion.

On the other hand, receiving support for an unrelated energy-efficiency measure does not automatically rule out BUS.

If you have previously received public funding, tell your installer exactly what the funding was for. They can then assess whether it affects the proposed application.

Does The Heat Pump Have To Meet Technical Standards?

Yes.

Even if the property itself qualifies, the proposed heat pump must also meet the scheme's technical requirements.

For example, eligible air-to-water and ground source heat pumps must have a minimum seasonal coefficient of performance (SCOP) of 2.8. The system must also be correctly sized to meet the property's full space-heating requirements and satisfy the relevant requirements for heating and hot water.

This is why the installer needs to assess the property before selecting the equipment.

A product appearing on Ofgem's Product Eligibility List does not by itself guarantee that the complete installation qualifies for BUS.

Does The Installer Need To Be MCS Certified?

Yes.

The installation must be carried out and commissioned by an appropriately MCS-certified installer for the relevant technology.

The homeowner does not normally submit the BUS application independently. Instead, the installer applies through Ofgem on the property owner's behalf after agreeing the installation and obtaining the necessary consent.

Choosing an installer with the correct certification is therefore part of meeting the scheme requirements, not simply a preference.

A Quick Eligibility Check

Your home may be suitable for BUS if most of the following statements apply:

• The property is in England or Wales.
• You own the property.
• It is not social housing.
• It is not an excluded new-build property.
• You are replacing an eligible fossil fuel or electric heating system.
• You are installing an eligible heat pump or biomass boiler.
• The proposed system meets BUS technical requirements.
• An appropriately MCS-certified installer will carry out the work.
• The same low-carbon heating installation has not already received excluded government funding.
• The installation can be completed within the scheme's required timeframe.

This is a useful starting point, but it is not a substitute for an official eligibility assessment.

How Do You Apply If Your Home Qualifies?

If you believe your property meets the requirements, the next step is to contact an MCS-certified installer.

To apply for boiler upgrade scheme grant funding, you normally:

1. Find an MCS-certified installer.
2. Arrange a property assessment.
3. Discuss the proposed heating system and receive a quotation.
4. Agree to the installation and grant application.
5. Allow the installer to submit the BUS application to Ofgem.
6. Confirm your consent when contacted.
7. Have the system installed and commissioned within the required timeframe.
8. The installer claims the grant and applies it as an upfront discount.

The BUS grant should be clearly shown on the quotation and invoice, so you can see the amount being deducted from the installation price.

What If Your Home Does Not Qualify?

Not qualifying for BUS does not necessarily mean that a heat pump is unsuitable for your property.

It simply means the particular installation does not meet the requirements of this funding scheme.

For example, a property could be outside the geographical area, fall into an excluded building category or have already received funding that prevents another BUS claim. In other cases, the proposed heating technology may not meet the scheme's technical requirements.

The important thing is to establish why a property is ineligible before abandoning the idea of upgrading its heating system altogether.

Final Thoughts

Whether your home qualifies for the Boiler Upgrade Scheme depends on several factors rather than the age or type of your boiler alone. Property ownership, location, existing heating, building type, previous funding, proposed technology and installer certification can all affect the outcome.

For an eligible home, the current support can make a substantial difference to the upfront cost of installing a heat pump, particularly where an off-gas-grid oil or LPG property qualifies for the £9,000 grant.

The most reliable way to confirm your position is to have an MCS-certified installer assess the property and proposed system against the current BUS rules before you commit to the work.
