Recommendation 22
22
Accepted in Part
DESNZ is developing improved data series and dashboards to monitor heat pump progress.
Conclusion
DESNZ told us that it was looking to produce a more regular data series that it could publish by combining some of its data sources. It was also developing a dashboard that will show the number of heat pumps installed through each government scheme. The NAO found that regular monitoring of progress would help DESNZ better understand whether it was on track to deliver an elevenfold increase in heat pump installations to reach its target of 600,000 installations by 2028. It found that it would also help to determine where further intervention may be required from government or industry.40
Government Response Summary
The government agrees to publish quarterly data for retrofit installations funded by the government by Winter 2024. However, it is still investigating methods to collect and publish data for new build and non-government funded installations, unable to commit until a suitable mechanism is found.

4.1 The government agrees with the Committee’s recommendation. Target implementation date: Winter 2024 4.2 The government agrees to publish data quarterly for retrofit installations using government funding. The government is also investigating whether there is a way to collect and publish data on installations in new build and installations not using government funding and cannot commit to do this until a suitable mechanism is found. 4.3 There is currently no single data source that measures the number of heat pumps installed. According to the Heat Pump Association more than 60,000 heat pumps were sold in 2023, including around 40,000 Microgeneration Certification Scheme (MCS) certified heat pump installations. However, new build and installations not using government funding are not systematically recorded by MCS. The department is currently exploring whether it is possible to use various data sources to cover these gaps. Across each of its schemes, the department currently publishes details on the number of measures installed on a regular basis, including heat pumps deployed, allowing for ongoing monitoring of the number of heat pumps installed.
