The Green Home Grant has now expired however a new government scheme is set to replace this. It’s called the Boiler Upgrade Scheme (BUS). This is set to go live on 23rd May 2022. Discover more.

What is the Boiler Upgrade Scheme (BUS)?

The government will provide grants to encourage property owners to install low carbon heating systems such as heat pumps, through the Boiler Upgrade Scheme (BUS). These grants will help property owners overcome the upfront cost of low carbon heating technologies. Not everyone can apply so you’ll need to check to see if you are eligible. Please feel free to contact our friendly team if you have any questions or would like to discuss your options.

You can get:

  • £5,000 off the cost and installation of an air source heat pump
  • £5,000 off the cost and installation of a biomass boiler
  • £6,000 off the cost and installation of a ground source heat pump


You may be eligible if you:

  • live in England or Wales
  • own your property (whether this is a home or a small non-domestic property)

The property will need to have:

  • an installation capacity up to 45kWth (this covers most homes)
  • a valid Energy Performance Certificate (EPC) with no outstanding recommendations for loft or cavity wall insulation (unless you have an insulation exemption)

New build properties will not normally be eligible. The only exception is if you’re building your own home.

Heppelthwaite the Red Van Plumbers can advise whether a low carbon heating system is suitable for your property.

If you’re claiming other grants or funding

You can still apply if you’ve received separate funding for energy efficiency upgrades such as insulation, doors or windows.

If you’re replacing an existing low carbon heating system

Funding is not available for the replacement of existing low carbon heating systems. Only properties which are fully replacing existing fossil fuel systems (such as oil, gas or direct electric) are eligible for support

“From the outset Heppelthwaite showed flexibility and competence, factors which were very important given the style of our house. At installation all those involved; scaffolders, roofers and electricians demonstrated professionalism and a high level of customer care. Nothing was too much trouble, and we have been left with an excellent result. We can highly recommend this organisation to anyone. Heppelthwaite was a pleasure to deal with and treated us and our home with utmost respect and consideration. As a well-established, family concern, we know they will be there when we need them in the years to come.”

“We originally chose Heppelthwaite for our installation as they seemed a friendly, professional and local family business. However, following the completion of our installation I would highly recommend this company to anyone. From start to finish we were made to feel like a very important client and every member of their team was good to deal with. We wanted to take maximum advantage of this generous Government Scheme as finding a good home for your savings is virtually impossible. Heppelthwaite worked closely with us to find the very best solution. We are very pleased with the result”
