If you’re a homeowner in Scotland exploring low‑carbon heating, here’s the key point: the Boiler Upgrade Scheme (BUS) does not operate in Scotland. BUS is a UK Government grant for properties in England and Wales only. In Scotland, support is provided through Scottish Government schemes—primarily the Home Energy Scotland Grant and Loan—plus GB‑wide programmes such as ECO4 and the Great British Insulation Scheme (GBIS).
For a clear, Scotland‑focused overview, see the independently hosted resource: Independent guide to Scotland boiler grants.
What is the Boiler Upgrade Scheme (and where does it apply)?

- Technologies: Air-source and ground-source heat pumps; limited biomass in rural/off-gas areas
