Boiler Upgrade Scheme (BUS)

The Boiler Upgrade Scheme (BUS) offers homeowners and landlords in England and Wales up to £7,500 off the cost of installing an air source or ground source heat pump. The grant helps reduce carbon emissions and energy bills by replacing old gas or oil boilers with modern low-carbon heating.
