Heat Pump Deployment statistics
Summary
DESNZ has expanded its heat pump deployment statistics to cover all UK heat pump installations (up to 45kW), not just those supported by government schemes. The statistics now provide quarterly data on total retrofit heat pump deployment including both air source and ground source heat pumps.
Why it matters
This provides better visibility of the overall heat pump market deployment rate, which is crucial for tracking progress against net zero targets and understanding demand-side electrification impacts on the grid.

Change to Heat Pump Deployment statistics release The latest release of the Heat Pump Deployment Official Statistics series took place on Thursday 12 March at 9.30am. In line with our ambitions to present as full a picture of total heat pump deployment in the UK, there will some changes to the statistics going forwards. From now on there will be increased coverage in the statistics, with ‘Total Retrofit UK Heat Pump’ deployment being presented, rather than only those heat pumps deployed with the support of DESNZ policies. Statistics about DESNZ low carbon heating schemes will continue to be available through their existing individual statistics releases, which have been linked below for ease.
