The report outlines that to meet the previous Government’s target of 600,000 heat pump installations per year by 2028, over 41,000 full-time roles will be needed across the whole heat pump workforce, rising to 122,000 by 2035 to meet the target of 1.6 million heat pump installations per year.

Covering not only heat pump installers but also the workforce needed from the electrical, plumbing, heating and groundwork trades, as well as the sales and admin resources required to support the transition, the findings outline the growth needed in the total heat pump market workforce to accelerate the deployment of heat pumps in UK homes.

With over 7,800 individuals completing a recognised heat pump qualification in 2023, a 133% increase in 2022 levels, and more than 7,000 having already completed training in the first three quarters of 2024, interest in the training is growing. However, the report reveals that despite positive growth in recent heat pump installer training rates, there is a gap between the number of trained individuals and active heat pump installers working in the market with around 39% of those who complete a training course currently not going on to install heat pumps.

Commenting on the report, HPA chief executive Charlotte Lee said: “The publication highlights the need for clarity and action from the Government to increase and sustain interest in heat pump training to meet the UK’s heat pump deployment targets.

The availability and provision of courses are not the limiting factors in this instance; rather, there is a lack of confidence in the market and uncertainty about the heat pump deployment pipeline.

Now is not the time for complacency. Although we have seen continued growth and interest in heat pump training, this momentum must continue.

It is essential that action is taken to encourage those trained to apply their skills and gain the experience that must go hand in hand with the training if we are to have the competent workforce needed to deliver the required growth at scale and speed.”

Commenting on the report, Dr Richard Hauxwell-Baldwin, head of policy, research and campaigns at The MCS Foundation, said: “Training rates to develop a skilled workforce to meet the demand of Net Zero heating are growing, but it is vital that those who train go on to install heat pumps in order to decarbonise UK homes. To ensure continued confidence and growth in the sector, the Government must introduce long-term policies such as the Future Homes Standard, making heat pumps the default in all new homes, and provide clarity to the market to support investment in the transition to clean heat.’

Alongside the publication of the report, the HPA have published data on its members' training capacity and geographical range which showcases the capability of the sector to train the new and existing workforce. Currently, HPA members have over 260 training sites which in total have the capacity to train in the region of 80,000 individuals a year.
