Department for Energy Security and Net Zero written question – answered at on 29 April 2025.
Sarah Gibson
Liberal Democrat Spokesperson (Business)
To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the comparative merits of (a) air-to-air and (b) other heat pump technologies eligible under the Boiler Upgrade Scheme.
Miatta Fahnbulleh
Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
The Boiler Upgrade Scheme does not currently support air-to-air heat pumps, as heat pump installations must provide both space heating and hot water heating, using liquid as a medium for delivering that heat. We want to target support at technologies that offer the greatest potential to decarbonise our buildings.
The Government is committed to incentivising moves to cleaner, more affordable heating, and will keep its position on alternative heating technologies under review and make further assessments as the supporting evidence base develops.
