Heat Pump Deployment statistics
Summary
DESNZ expands heat pump deployment statistics to capture all retrofits in the UK, not just those supported by government schemes. The change aims to track total market deployment rather than only policy-supported installations. Data tables provide quarterly counts of hydronic heat pumps up to 45kW capacity.
Why it matters
This statistical expansion reflects the government's desire to claim credit for market-led heat pump adoption alongside its direct spending programmes. As such, it is redistributive data presentation rather than structural market reform — it treats symptoms of expensive heating rather than addressing energy supply or market structure.
Key facts
- •Statistics now cover all UK retrofit heat pumps, not just DESNZ scheme-supported ones
- •Covers hydronic heat pumps up to 45kW capacity
- •Quarterly reporting frequency maintained

Memo
## 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.
