Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment she has made of the reasons for change in the mean cost of heat pump installations through the Boiler Upgrade Scheme.

With the growth in heat pump demand encouraged by the Boiler Upgrade Scheme (BUS) in combination with the Clean Heat Market Mechanism, Government expects to see continued real terms cost reductions over time.

Government actively engages with installers and suppliers participating in the scheme, and will continue to monitor BUS scheme data, wider industry data, and use the outputs of the BUS evaluation programme to understand price trends.
