Wolseley Group has published a new report highlighting both the scale of the UK’s transition to heat pumps and the real opportunity this presents for the installer community.

Launched at a reception at the Houses of Parliament hosted by Matt Western MP, the report shows that hitting the UK's heat pump installation and net zero targets means rapidly expanding the trained installer base and removing barriers that currently make the switch harder than it needs to be. The number of installation must also increase fifteen-fold.

Emily Nurse, Head of Net Zero at the Climate Change Committee, and Prof. Jan Rosenow, Professor of Energy and Climate Policy at Oxford, both spoke at the launch event before John Hancock, Chief Operating Officer at Wolseley Group, presented the headline finding of the reports.

Key findings include:

  • The UK will need seven times more trained installers by 2035, with some areas, such as Lancashire, requiring an eight-fold increase
  • Installers moving into heat pumps could earn £9,145 more per year than those focusing solely on boilers
  • Consumer interest is growing: 26% of homeowners are now likely to install a heat pump, up from 19% in 2021

Wolseley has already begun scaling up to meet demand. The business has invested in a 100,000ft2 fulfilment centre, opened Renewables Centre locations across the UK, and trained more than 250 installers since June 2025. Its Start at Home scheme, backed by the think tank Nesta, gives installers access to free training, up to £7,500 worth of materials, and full MCS support, giving them confidence and practical experience by fitting a heat pump in their own home.

Hancock commented: “Installers are at the heart of the UK’s low-carbon future and they can’t be expected to make the transition alone. Our report highlights not just the scale of the challenge, but the practical support needed to get there: training, investment in supply chains, and clear long-term policy signals.

"We’ve seen this kind of transformation before, when Wolseley helped drive the rollout of gas heating in the 70s and 80s. Now we have an opportunity to do it again, supporting the trade to grow their businesses and lead the shift to low-carbon heating.”

Wolseley’s policy recommendations include:

  • Extending the Heat Training Grant to March 2029 and rolling it out across Scotland and Wales
  • Publishing clear timelines for the Future Homes Standard and Minimum Energy Efficiency Standards
  • Strengthening consumer protection and supporting a flexible approach – so installers can choose the right solution for each home.
