Receive a £7,500 grant with the Boiler Upgrade Scheme (BUS) The Government-backed Boiler Upgrade Scheme has recently been introduced to help property owners switch to a low carbon heating system, with a £7,500 grant towards the cost to supply and install an Air Source Heat Pump. The scheme runs until 2025 and is open to domestic and small non-domestic properties in England and Wales.



Frequently asked questions

To claim the BUS grant, you'll need to check off the following:

  • You'll need to own your home.
  • You'll need to have an EPC from the past 10 years. If you don't, no worries.
    We can arrange that for you.
  • You'll need to check you have enough space for your new system. Check out our sizing guide here.
  • If your home is undergoing renovation you'll need to wait until it's complete. In the meantime, here are some tips to help you on your way.

To apply for the Boiler Upgrade Scheme (BUS), you will need to find an eligible installer who is registered with TrustMark or Microgeneration Certification Scheme (MCS).

The installer will help you through the application process, including submitting the application on your behalf.

The outside bit of a heat pump is roughly 1m x 1m x 2m (or to help you visualise - the size of a moped). It needs a space of around a meter in-front and to each side to breathe.

Inside you need space for a hot water tank - 2m x 1m x 1m (the size of a modern fridge freezer), on the ground or first floor of your home (the closer to the outside the better).

The cylinder can also be installed in a garage, outdoors in a purpose-built store, or in the loft, but this may decrease efficiency (it takes more energy to heat the water when the cylinder is exposed to the cold).



If you don't have the room right now, new space saving technology is being developed all the time, so expect this to come down considerably in future (more on this to come 👀).
