The UK’s heating industry is approaching a critical turning point. As demand for air source heat pumps and renewable heating grows, the sector faces a major shortage of skilled plumbers and heating engineers. With many tradespeople nearing retirement and too few new entrants joining the field, this skills gap threatens to slow the nation’s low-carbon transition. But with the right investment in training, apprenticeships, and green technology, the industry has a chance to turn this challenge into an opportunity for lasting change.
