Statistics

Accurate data is the basis for effective policy and business decisions to support the accelerated deployment of heat pumps in the UK. 

HPA UK collects and publishes robust heat pump factory gate sales and training data, offering a transparent evidence base to inform policy development, market analysis and workforce planning.

By making this data available to the public, HPA UK aims to facilitate collaboration and support the wider sector in understanding trends and guiding informed action. Members of HPA UK receive this information more frequently. Find out more about membership here.

Heat Pump Sales in the UK

Dive into the latest figures on heat pump sales, showcasing the growth in UK heat pump sales.

Our statistics are gathered through a combination of utilising data provided by HPA UK manufacturing members and using market estimation techniques to extrapolate the data to represent the full UK Heat Pump market.

This data includes factory gate sales of Air-to-Water (A2W) monobloc units, Air-to-Water (A2W) split units, Ground and Water Source units, domestic hot water heat pumps (DHWHP) and “other”- which includes , Exhaust Air Heat Pumps and Integrated Hybrid Heat Pumps.

NOTE:
1. It does not include air to air heat pumps and therefore makes it incomparable to many EU data sources.
2. Prior to 2024, DHWHP are included in the “Other Heat Pumps” figures.
3. In March 2025 the previously reported numbers for Ground/Water Source Heat Pumps were retrospectively updated, representing increased levels of sales evidenced in additional data that became available for the whole period 2019-2024.
4. UK Manufactured is defined as to ‘Be wholly produced, manufactured, or assembled within the UK, or have been significantly changed through a treatment or process within the UK.”  “Significantly changed’ occurs when the UK based manufacturing or processing gives the heat pump its essential character. This means UK processes involve the manufacture or assembly of multiple major internal component systems (e.g. integration of the refrigerant circuit, charging and sealing of the system, installation of heat exchangers, integrating electronics, adding the hydronic water circuit, etc.) to create a finished unit that is materially different from its imported parts.

Qualified Heat Pump Installers

The backbone of the heat pump revolution lies in the skilled professionals equipped to install these systems.

To the left you’ll find HPA UK data gathered on the number of individuals who successfully completed training to install Heat Pumps in the UK.

NOTES:

  1. Data referenced in this release is based on the number of individuals who have successfully completed one of the Heat Pump training courses that are eligible for the Heat Training Grant.
  2. The data does not include apprenticeships. The Low Carbon Heating Technician Apprenticeship was approved in 2023, and the first completed apprenticeships will begin to be reported towards the end of 2026. To the end of Q1 2026, 441 individuals had completed the Refrigeration Air Conditioning and Heat Pump Engineering Technician apprenticeship which has been active since 2018.

Cumulative total of individuals trained to install heat pumps in the UK

To the right you’ll find HPA UK data gathered on the cumulative total of individuals who successfully completed training to install Heat Pumps in the UK.

The targets are expressed as upper and lower estimates of the training needed to meet the Warm Homes Plan target of installing over 450,000 heat pumps per year by 2030.

The upper estimate would provide the maximum flexibility of trained resource to react to growing demand and is based on the expected workforce in 2035 which is beyond the period of the Warm Homes Plan.

The lower estimate is the absolute minimum training necessary to meet the Warm Homes Plan by 2030 and would require an increased training rate from 2030 to 2035.
