Heat pumps are seen by the government as a vital tool in cutting the carbon emissions from people heating their homes.
To enable more people to benefit from this as well as other low-carbon technologies and to enable the switch from fossil fuel-based heating systems, BUS was introduced in April 2022.
In 2023, the government’s £450m BUS was recently extended until 2028, offering grants of £7,500 towards the cost of a new heat pump.
Home heating accounts for 18% of UK greenhouse gas emissions, despite the government having introduced the BUS Nesta report last year showing that uptake of low-carbon alternatives such as heat pumps has been very slow.
However, according to the government, demand for heat pumps is now surging. March 2025 saw 4,028 applications for BUS – up 88% on the same month last year...
