Heat Pumps
The question
To ask the Secretary of State for Energy Security and Net Zero, for what reason air to air reversible heat pumps do not qualify for the (a) Clean Heat Market Mechanism and (b) Boiler Upgrade Scheme.
Answered by Martin McCluskey
The Clean Heat Market Mechanism is focused on developing the market and supply chain for upgrading homes with hydronic heat pumps – a core technology for the UK’s transition to cleaner heating since around 90% of UK homes have water-based central heating systems. The Government will keep the scope of the scheme under regular review.
The Government has published a response to the consultation on proposed Boiler Upgrade Scheme changes, confirming grants of £2,500 for air-to-air heat pumps in domestic properties, starting in 2026. This will increase consumer choice and support the UK’s transition towards low carbon heating systems.
