Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what information his Department holds on the (a) number and (b) type of (i) heat pump and (ii) boiler unit sold by each obligated boiler manufacturer, in the context of the Clean Heat Market Mechanisms; and what assessment his Department has made of the potential merits of publishing these figures on a regular basis.

The Department will receive independently verified annual gas and oil boiler sales data from scheme participants after the completion of each scheme year via the scheme’s administrator, the Environment Agency. Further detail on these reporting processes can be found in the published scheme guidance. It also has access to heat pump installations data from the Microgeneration Certification Scheme and publishes statistics on Government-supported installations at https://www.gov.uk/government/collections/heat-pump-deployment-statistics.

The Department is considering the options to publish some Clean Heat Market Mechanism scheme data, for example aggregated annual verified sales and installation data, but needs to assess commercial sensitivities in doing so.
