What the Boiler Upgrade Scheme covers
The Boiler Upgrade Scheme (BUS) is a government grant towards the cost of installing an air source, ground source, or biomass heating system in England and Wales, in place of an older fossil-fuel boiler.
The exact grant amounts, eligibility rules, and how the grant is applied are set out on GOV.UK. See our dedicated grant page for the figures, quoted directly from GOV.UK and checked on the date shown.
The grant is paid to your MCS-certified installer, who deducts it from your invoice — you don't apply for the money yourself, your installer handles the paperwork as part of the job.
Because eligibility and figures can change, always confirm the current position on GOV.UK before you commission any work, rather than relying on a figure you've seen elsewhere.
