The Boiler Upgrade Scheme (BUS) statistics provide information to monitor the uptake of the scheme, which contributes upfront capital grants to support the installations of low carbon technologies. These include air source heat pumps (ASHP), ground source heat pumps (GSHP), ground source heat pumps shared ground loops (GSHP SGL) and in some circumstances biomass boilers, in domestic and small non-domestic buildings.

The data tables provide monthly and cumulative analyses on voucher applications and redemptions.

These statistics are provisional and are subject to future revisions.

Historical releases are available on request, see contact details below.
