PARLIAMENTARY WRITTEN QUESTION
(19 June 2025)

To ask the Secretary of State for Energy Security and Net Zero, what assessment his Department has made of the potential impact of hybrid heat pumps on (a) consumer energy bills and (b) UK greenhouse gas emissions.

Asked by:
Mark Garnier (Conservative)

The specific greenhouse gas emissions and running costs of a hybrid heat pump are impacted by a range of factors including the proportion of heating met by the heat pump. However, the Government noted in the recent ‘Raising product standards for space heating’ consultation that hybrids could reduce fossil fuel usage and reduce a consumer’s bills, depending on wider energy pricing and other factors.

The Government will publish a response to this consultation in due course and will continue to gather and assess evidence and monitor market developments in relation to hybrid heat pumps.
