The Boiler Upgrade Scheme

What you can get.

You can get one grant per property. Current grants are available for:

  • £7,500 towards an air source heat pump
  • £7,500 towards a ground source heat pump (including water source heat pumps and those on shared ground loops)
  • £5,000 towards a biomass boiler


The grants for heat pumps went up on 23 October 2023. If you applied before 23 October and your installer has not fitted your new heat pump yet, talk to them about cancelling your grant and reapplying to get the increased amount.


You cannot get a grant for a hybrid heat pump system (for example a combination of gas boiler and air source heat pump).

The system you install must meet certain standards, such as minimum efficiency levels (your installer can advise you on these).

The system’s maximum capacity must be less than 45kWth – anything over is not eligible.

You cannot get a grant to replace a low carbon heating system.
