What the wider market is doing

Across construction, demand is softening: the UK Construction PMI was 43.6 in October 2026 (S&P Global UK Construction PMI, 5 Nov 2026) and the CPA expects private housing repair, maintenance and improvement work to fall 8% in 2026 (CPA Autumn forecasts, 26 Oct 2026). Training takes time, so it's worth thinking about where demand will be when you qualify, not just today. See all demand signals.
