Still, certainty and increased consumer demand are needed to encourage trained individuals to become active in the workforce.

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.

This number will rise to 122,000 by 2035 to meet the target of 1.6 million heat pump installations annually.

The findings cover heat pump installers, the workforce needed from the electrical, plumbing, heating, and groundwork trades, and the sales and admin resources required to support the transition.

They 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 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.

Alongside the report's publication, the HPA has published data on its members' training capacity and geographical range, which showcases the sector's capability to train the new and existing workforce.

Currently, HPA members have over 260 training sites, which, in total, have the capacity to train approximately 80,000 individuals a year.
