The Boiler Upgrade Scheme

The Boiler Upgrade Scheme provides grants to encourage property owners to replace existing fossil fuel heating with more efficient, low carbon heating systems.

Through the Boiler Upgrade Scheme, you could get a grant to cover part of the cost of replacing fossil fuel heating systems with a heat pump or biomass boiler.
Fossil fuel heating systems include oil, gas, electric or LPG (liquefied petroleum gas).

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

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 maximum capacity is 45kWth for individual systems and 300kWth for shared ground loops.
