Are heat pump installers getting busier or quieter?
Busier. Longest wait of any common home trade (median 14 weeks) and lengthening year on year per TradeMatch; the CPA says heat pump activity is still growing while wider home improvement shrinks. Across construction as a whole, most indicators point quieter: the UK Construction PMI was 43.6 in October 2026.
