This guide offers every requirement that a property owner has to meet before applying to the boiler upgrade scheme. It helps you understand the eligibility criteria clearly. The scheme supports clean, renewable energy solutions by replacing an old fossil fuel boiler with low-carbon systems.
The boiler upgrade scheme provides grants to switch your heating system. It supports heat pumps and biomass boilers. This includes air source heat pumps, ground source heat pumps, and biomass boilers. It also includes water source heat pumps in some cases.
The aim is simple. Reduce carbon emissions and improve energy efficiency. Cut rising energy bills for owners in England and Wales. Let us explain who is eligible for the scheme.
Why Does the Boiler Upgrade Scheme Have Criteria?
The scheme uses public money. So, strict scheme requirements apply. The government wants fair use of funds. The goal is to replace fossil fuel heating systems. This includes a gas boiler, oil, or LPG systems. It also covers electric heating like storage heaters. If your home already has a heat pump or biomass boiler, you cannot apply. This avoids double government funding or support.
The rules also check the property’s energy efficiency. Homes should meet minimum insulation standards. You may need loft or cavity wall insulation first. These criteria for the boiler upgrade ensure proper performance. They also protect long-term energy-saving results.
Air Source Heat Pump Grants
Who Set the Criteria?
The UK Government created the scheme. It applies to England and Wales only. Ofgem manages the grant system. You will receive an email from Ofgem after voucher approval. The scheme works under strict quality controls.
Installations must follow MCS standards. This means the installer must follow the Microgeneration Certification Scheme. Always find an MCS-certified installer first. Your chosen installer will handle most paperwork.
Who Can Apply?
This is the most important section. Here, we focus on who can apply for the boiler upgrade.
Homeowners
A property owner can apply directly. You must own the property. The property must be in England and Wales. You must have a valid energy performance certificate. An EPC is also called an energy performance certificate. The EPC must be issued within the last ten years.
Your home must use a fossil fuel heating system. This may be a gas boiler, oil or gas boiler, or LPG system. It can also be certain types of electric heating. If you meet these eligibility criteria, you may qualify for the BUS.
Landlords
Landlords can also apply for the BUS grant. You must own the rental property. The same EPC and heating rules apply. The property must not have already been given government funding or support.
It must not be supported under the Energy Company Obligation scheme. If you meet the conditions, you are eligible for the grant.
Domestic and Small Non-Domestic Buildings
The scheme supports homes and some commercial buildings. This includes mixed-use buildings. The building must have a qualifying fossil fuel boiler.
Self-Build and New Build Properties
The boiler upgrade scheme self-build process has special rules. Some self-build properties can qualify. Your property is a self-build if you built it mainly yourself. It must never have been owned by a business. It must not be part of excluded developments.
The self-build application process differs slightly. Speak with your MCS-certified installer for guidance. Most new-build properties do not qualify. However, some new-build homes with fossil fuel systems may qualify.
Self-build homes cannot claim biomass support. This is part of the scheme requirements. For Scotland, contact Home Energy Scotland. They offer separate funding for energy improvements.
Technology-Specific Eligibility
Switch To Air Source Heat Pump
You may qualify for an air source heat pump grant. The property must not already have renewable heating. No existing heat pump or biomass boiler is allowed. There must be a proper electricity supply. Installing a heat pump requires adequate outdoor space.
The heat pump installation must be done by an MCS installer. The installer must apply and claim the grant on your behalf. The BUS grant helps reduce upfront costs. The boiler upgrade scheme grant for a ground source heat pump is higher.
Switch To Ground Source Heat Pump
A ground source heat pump offers strong efficiency. It uses underground pipes for ground source heat. Installation takes more planning time. Groundworks must begin months before ground source heat systems. You must apply weeks prior to the heat pump installation. The installer will manage the BUS application. They will help you secure your grant.
Switch To Biomass Boilers
Biomass boilers are mainly for rural homes. The property must be off the gas grid. Urban homes rarely qualify. Self-build homes cannot apply for biomass support. This is clearly stated in the eligibility rules.
What Makes You Ineligible?
You are not eligible for the boiler upgrade if:
- The property already has renewable heating.
- It has already been given government funding.
- It received support for a heat pump under another scheme.
- The system is funded under ECO.
- The property is social housing.
- The building is under development.
If you received government funding or support before, you cannot double claim.
What If You Do Not Meet the Criteria?
You may still apply later. First, improve your home’s energy efficiency. Install proper insulation. Add loft, cavity wall insulation, or floor insulation. Improve the property’s energy rating. A better EPC improves your chances.
You can also explore the Energy Saving Trust or contact our grant experts for advice. They provide guidance for property owners. After upgrades, you may still apply. Then you could qualify for the grant.
Applying for the Grant
The application process is simple. First, find a certified installer in your area. Make sure they are MCS certified installer approved. The installer checks if you’re eligible. They confirm your eligibility criteria.
Your installer submits the grant application. They apply for the BUS grant and handle paperwork. They will get a voucher from Ofgem. After installation, they redeem the voucher. The scheme provides funding directly to the installer. They usually apply for and get a grant on your behalf. This reduces your upfront payment.
Why Property Owners Apply
Many owners apply to upgrade old systems. They want better energy-efficient homes.
Reasons include:
- Lower annual energy bills.
- Protection from rising fuel prices.
- Switch from oil or gas boiler systems.
- Improve indoor comfort.
- Reduce carbon emissions.
- Support national climate goals.
The scheme supports renewable energy adoption. It helps replace old fossil fuel heating with air source heat or ground systems.
Conclusion
Understanding qualification criteria is very important. The boiler upgrade scheme supports clean heating transitions. If you are a property owner in England and Wales, check carefully. Make sure you meet all scheme requirements. Have a valid energy performance certificate. Ensure your home uses a qualifying fossil fuel heating system.
If you meet the conditions, you are eligible for the scheme. Then you can apply for the boiler upgrade confidently. Speak to an MCS-certified installer first. They will confirm eligibility and manage the process. With the right steps, you can upgrade your heating system. You can reduce emissions and secure long-term energy-saving benefits.
Frequently Asked Questions
Only homeowners and landlords of properties located in England and Wales can apply for BUS grants. The property must have a valid EPC and use a fossil fuel or electric heating system (except a heat pump).
Yes! A valid Energy Performance Certificate issued within the last 10 years is required for old properties. However, new build properties that are self-built can apply without an EPC.
Not at all! Properties with an existing heat pump or biomass boiler are strictly prohibited from applying for the Boiler Upgrade Scheme because they are already on low-carbon heating.
You must contact an MCS-certified installer, who checks eligibility and submits the grant application on your behalf after a technical assessment of your property.
