UK Construction PMI Rises to 46.1 in September — Slowest Decline in Eight Months
What happened
The S&P Global/CIPS UK Construction Purchasing Managers' Index rose to 46.1 in September, up from 44.3 in August — marking the weakest rate of decline since January 2026.
The index remains below the 50.0 threshold that separates contraction from growth, meaning the sector is still shrinking. But the pace is easing. Tim Moore, Economics Director at S&P Global Market Intelligence, noted that total new orders remained "relatively subdued" as clients deferred decisions on major projects and sales conversion cycles lengthened.
Housebuilding was again the weakest-performing subsector, followed by civil engineering. Commercial construction showed only a marginal decline. The improvement from August's 44.3 reading suggests the floor may be forming — but recovery is still some way off.
What this means for tradespeople
The headline is encouraging but don't confuse "less bad" with "good." At 46.1, the construction sector has now contracted for over a year straight. For self-employed tradespeople, that means fewer new projects filtering through from developers, longer gaps between jobs, and more competition for domestic work.
If you're a plumber, electrician, or builder relying on residential work, the housebuilding sub-index is the one that matters — and it's still deep in contraction. The commercial side is stabilising, which may help trades working on fit-outs and refurbishments.
The practical takeaway: when work is harder to win, your reputation is your pipeline. Tradespeople with strong Google reviews and a visible online presence are the ones who stay busy when the market tightens.
What to do about it
- Keep your Google Business Profile active. Post updates, respond to reviews, and keep your photos current. When homeowners are choosing between five plumbers, the one with 40 recent reviews wins.
- Ask every happy customer for a review. In a tighter market, each review is worth more. TapReview is a £9/month tool that helps UK tradespeople get more Google reviews with one tap — sending automated review requests via WhatsApp and SMS after every job.
- Diversify into commercial if you can. The commercial sub-index is stabilising — trades with commercial experience may find more opportunities there.
