Boiler upgrade scheme

Are you interested in installing a low carbon heating system, but are worried about the initial cost? Have you heard about the boiler upgrade scheme (BUS)?

From April 1st, 2022, the government will be offering grants to encourage property owners to upgrade their boilers to low carbon heating systems, such as heat pumps through a boiler upgrade scheme (BUS). The scheme will run from 2022 to 2025 and will be available in England and Wales for owners of domestic and small non-domestic properties.

In a bid to offer support and promote low carbon heating solutions, Swale Heating can assist customers through the grant process. You will require an EPC certificate for your property to apply for a grant. You can find or apply for an EPC certificate for your property online at

The grant offers the following:

  • £7,500 off the cost and installation of an air source heat pump
  • £5,000 off the cost and installation of a biomass boiler
  • £7,500 off the cost and installation of a ground source heat pump

Hybrid-style pump systems are not available under the grant.

In order to be eligible for the scheme, you must:

  • Live in England or Wales
  • Own your own property
  • Have a property that has an installation capacity of up to 45kWth
  • Have a current EPC with no outstanding recommendations for loft or cavity wall insulation

Due to this, landlords are also eligible for the grant. What’s more, you can apply for the BUS even if you’ve claimed for other grants or funding for energy efficiency upgrades.

However, if your property has already received funding or support for a heat pump or biomass boiler, then you will not be eligible for the scheme.

Additionally, the heat system that is installed under this grant must meet the following criteria:

  • The new renewable system must meet the full space heating and hot water requirements for the property
  • The new renewable system must replace an existing fossil fuel heating system, including gas and electric
  • The new renewable system must meet particular standards, including minimum efficiency requirements

You are not able to receive this grant to replace any existing low carbon heating systems you may already have.  

This funding works a little differently compared to other grants as installers apply for the grant on your behalf. Once your installer has visited the property and determined which type of installation is appropriate for the property, a quote will be agreed upon. You will then receive an email from Ofgem to confirm that your chosen installer is acting upon your behalf.

Thankfully, our engineers at Swale Heating are MCS registered, so we can advise you on the best renewable option for your property before applying upon your behalf.

Swale Heating specialise in the installation of air-source heat pumps. We have a dedicated renewable heating solution team who are all MCS certified. MCS is an industry-led quality assurance scheme, which demonstrates the quality and reliability of approved products and installation companies.
