About Us | Clarke Talbot Renewable Energy Ltd

The Boiler Upgrade Scheme (BUS) supports the decarbonisation of homes and small non-domestic buildings in England and Wales. The scheme provides upfront capital grants of up to £7,500 to encourage property owners to replace existing fossil fuel heating with more efficient, low carbon heating systems such as air or ground sourced heat pumps.

These grants help property owners overcome the upfront cost of installing a low carbon heating system.
