The Heat Pump Association, the Ground Source Heat Pump Association and the Heat Pump Federation have merged to form a single body, HPA UK. The organisation said the transition followed "the successful merger of the Heat Pump Association, Ground Source Heat Pump Association and Heat Pump Federation", reflecting what it describes as an expanded role in unifying the sector1.
HPA UK states that it represents over 350 member organisations working in the heat pump sector, and that its members account for around 90% of the volume of heat pumps sold in the UK market1. Its membership is given as manufacturers of heat pumps, components and associated equipment, alongside energy companies, certification bodies, installers and training providers1. The merger brings together bodies that previously covered the sector separately, including the ground source specialists whose technology is described in our guide to ground source heat pumps and in the heat pumps hub.
The announcement of the merger came alongside the publication of new analysis by HPA UK, titled From Carbon to Competitiveness: The UK Opportunity Associated with Decarbonising Residential Heating1. The report models accelerating the deployment of decarbonised heating in line with the Government's Carbon Budget and Growth Delivery Plan for 2025 to 2035, and is based on Government assumptions published in that plan together with modelling generated from data in the Climate Change Committee's Seventh Carbon Budget1. It focuses on residential space heating appliances: hydronic heat pumps, fossil fuel boilers and direct electric heating1.
The headline figures in that analysis are set out below.
| Measure | Figure given |
|---|---|
| GVA from residential heating, today | £12.2 billion |
| GVA from residential heating, 2035 | £22.5 billion (an 85% rise from 2025) |
| Heat pump manufacturing, installation and use, 2025 | £1.0 billion |
| Same, opportunity by 2035 | £15.0 billion |
| Heat pump related employment growth by 2035 | Over 110,000 full-time equivalent jobs |
| Share of residential heating sector jobs | 82% |
| UK manufacturing expansion by 2035 | Between 15-fold and 27-fold |
| Gas demand fall, 2025 to 2035 | 63 TWh |
| Reduction in overall UK air pollution by 2035 | 6% |
| Carbon abatement from heat pump rollout | Up to 17 MtCO₂e annually by 2035 |
Charlotte Lee, HPA UK's Chief Executive, said:
"Today's findings show that decarbonising residential heating should not be viewed as a cost burden, but a major economic opportunity. Heat pumps can drive billions of pounds in growth, support tens of thousands of skilled jobs across the country and strengthen the UK's energy security by reducing reliance on imported gas. With the right long term policy clarity, the UK can build a world-leading heat pump industry, grow our domestic manufacturing, and deliver cleaner, healthier homes for millions of residents."
The report notes that the assumptions in the Warm Homes Plan are presented on a different basis from the Carbon Budget and Growth Delivery Plan, and would represent slower growth up to 2030, followed by a 9% increase in the heat pumps to be installed from 2031 to 2035 to realise the opportunities included in the report1.
Why it matters for households
The merger concentrates the sector's representation in one body at a time when the analysis it published puts the economic case for heat pumps at the centre of the debate. For a household considering a heat pump, the practical questions are largely unchanged: what the equipment and installation cost, what it costs to run, and what happens to the home's exposure to gas prices. The report's claim that gas demand could fall by 63 TWh between 2025 and 2035 is a national figure, not a household one, but it points to the direction of travel the industry is arguing for1.
Ground source systems, which the Ground Source Heat Pump Association represented before the merger, are one of the options covered by the sector. Our pages on ground loops and boreholes and shared ground loop networks explain how those installations work, and ground source heat pump cost sets out what is known about pricing. The report does not give household-level cost or saving figures, and no per-home running cost estimates have been reported in it1.
Two of the quoted responses to the analysis focus on electricity prices rather than equipment. Chris Galpin of the climate think tank E3G said the UK "should stop overtaxing electricity to unlock billions more in additional investment towards these bill-saving home upgrades", and Garry Felgate of The MCS Foundation said it is "critical the Government reduce disproportionately high electricity prices"1. Neither statement sets out a specific policy or rate.
What happens next
HPA UK has opened registration for a free webinar on the analysis1. The report and its executive summary are available to download1. No date has been reported for any Government response to the analysis, and no further detail on the merger's governance has been published beyond the statement that it has completed1.
