What is the Boiler Upgrade Scheme?

In order to help the United Kingdom reach its target of net-zero by 2050, and to make sure all new heat pump installations are low carbon by 2035, the British government is investing £450 million in green home improvement. This has taken the form of the Boiler Upgrade Scheme (BUS), previously known as the Clean Heat Grant, and is designed to help households shift to low carbon heating units.

This government-run scheme focuses on lowering carbon emissions emitted by domestic buildings that continue to rely on fossil fuels and allowing the phasing out of its use in the years to come. The scheme will also be a step forward towards the government’s pledge of installing 600,000 heat pumps every year by 2028.

From 25th May, the Boiler Replacement Programme will make up to £6,000 worth of vouchers available to eligible households to purchase and install eco-friendly heating units like heat pumps. Additionally, the grant is likely to replace the Domestic Renewable Heat Incentive (RHI), ending in March 2022.

The Heat Pump Grant is available only in England and Wales, meaning that unfortunately, those living in Scotland won’t be able to reap the benefits.


How Does the Scheme Work?

The Boiler Upgrade Scheme 2022 will work similarly to The Green Homes Grant Scheme, whereby the British government will offer a fixed amount towards the price of renewable heating units, with the rest being paid by the homeowner.

However, the government is operating a “first-come, first-served” basis for those who meet the eligibility criteria, meaning homeowners will have to get themselves registered with an installer as early as possible.


How Do I Apply for the Boiler Upgrade Scheme?

Although precise details are yet to be shared by the government, two stages of application have been proposed so far:

  • Applying for Your Voucher – As your installer, JL Phillips will take care of this step for you to ensure a smooth process. 
  • Redeeming Your Voucher – This step will be initiated by your installer, such as JL Phillips, as it’ll confirm the process of completed paperwork and proof of installation.

The government, however, has also mentioned that they’ll be working closely with the grant administrator to create a digital solution and detailed design of the administration to make sure it works for every applicant.


How Long Do the Vouchers Last?

Once the scheme is launched, provided you meet the eligibility criteria, you can apply for the grant vouchers.

These vouchers come with a set validity period to make sure applicants are using them in a timely manner, and that the unused ones can be recycled later. In terms of the validity period, vouchers offered for Biomass Boilers and ASHPs last for approximately three months whereas for GSHPs, the validity is nearly six months.


Am I Eligible for the Boiler Grant 2022?

Although the eligibility criteria for the Boiler Upgrade Scheme will be similar to Domestic RHI, based on the latest government information, a guideline has been created to help homeowners understand what’s required to be qualified for the grant.

All homeowners including small and private landlords can apply for the scheme so long as they meet the following:

  1. Your property needs to have a valid EPC (Energy Performance Certificate) issued within the last 10 years. Having an EPC will not only show how energy-efficient your building is, but also give it a rating between A (very efficient) to G (least efficient). This will further help understand the amount of carbon emissions emitted by your home and how expensive it is to heat the property.
  2. While it’s important to have an EPC, you need to ensure that there aren’t any outstanding recommendations for cavity or loft wall insulation. You can be exempted though, provided the property is located in a conservation area or is government-listed.
  3. For you to qualify for the grant, your home should either be a custom-made building or an existing one. This criteria is the same as for domestic RHI, meaning that new builds will NOT be eligible. The reason being, it’s complicated and expensive to transition retrofits to low carbon heating when compared to new builds.
  4. You must get your requirements assessed and show at least one quote from a qualified and MCS certified installer like JL Phillips to be eligible for the scheme. While applying for the voucher is your responsibility, your installer will redeem it for you as that ensures the voucher is being put to good use.

Which Systems Are Covered Under the Scheme?

The Government Boiler Upgrade Scheme will support the following types of systems:

While biomass boilers are covered under the grant, only those installed in rural areas with a population of 10,000 or less are considered. They won’t be applicable for installation in urban areas.

Which Systems Aren’t Covered Under the Grant?

The heat pump grant also covers installations offering water heating and space in the property, but it excludes systems like:

  • Hybrid Heat Pumps
  • Hydrogen Boilers

Solar thermal won’t be supported, however, they can be installed as part of a biomass or heat pump system covered under the grant. You need to ensure the heating unit meets the full water heating and space requirements of your home.


How Does It Differ From the Domestic RHI?

The RHI operates through a tariff-based system, where the payment varies based on the property and its efficiency. Moreover, the payment is made on a quarterly basis over a period of seven years after the unit is installed. In contrast, the Boiler Grant offers vouchers covering upfront expenses of up to £6,000 for the heating system being installed.


What Can I Expect from the Boiler Upgrade Scheme?

As mentioned earlier, the upcoming Boiler Upgrade Scheme focuses on helping households transition to a low carbon heating system while enabling them to cut down on their carbon footprint. It is a step towards achieving the net zero target by 2025.

If you’re looking to make the switch to a low carbon heating system and would like to take advantage of this grant, speak to JL Phillips or a certified heat pump installer.
