PMI at 44.3: Why the Downturn Isn't Delivering Cheaper Tenders

6 September 2026 · 4 min read · Market Intelligence

August's PMI makes grim reading at the headline level: 44.3, the twentieth consecutive sub-50 reading and a deeper contraction than forecasters expected. The drag is housebuilding — a sharp, accelerating fall in residential activity more than offset slower declines in commercial and civil engineering. But underneath, the picture is more nuanced than the headline suggests: new orders are still falling, yet at the gentlest pace in a year, and firms cut jobs at the slowest rate since September 2025. Read in isolation, that looks like a market with spare capacity and pricing power drifting towards clients.

In practice, it isn't. The pricing data tells a different story. BCIS reports tender prices up 1.0% in the latest quarter and 3.2% across the year, with further increases of around 2.1% expected over the next twelve months and roughly 15% cumulatively over five years. Output is falling; prices are not. For anyone preparing a cost plan or development appraisal right now, that gap is the single most important fact in the market.

A Downturn Without Price Relief

Why does a shrinking market keep getting more expensive? Three reasons stand out. First, capacity has already left: two years of elevated insolvencies removed subcontractors and specialists from the supply chain, and the firms that remain are pricing for balance-sheet risk, not volume. Second, input costs persist — BCIS flags renewed materials pressure in aluminium, steel, electrical cable and aggregates, with energy-intensive products and long supply routes exposed to Middle East disruption, while scarcity in MEP, civil engineering and specialist groundworks trades keeps localised labour pressure alive even as general wage inflation moderates. Third, risk is being priced: tier one contractors are selecting which opportunities to pursue, favouring two-stage and negotiated routes, and single-stage fixed prices are increasingly difficult to secure — or carry a stiff premium when they are.

The Two-Speed Picture

The headline number also hides sharp divergence. RICS's latest commercial property survey shows tenant demand improving for a second quarter, but the recovery is concentrated in London. Infrastructure and public-sector-backed work retains the strongest pipelines, while private housing contends with a sharp repricing in mortgage rates and weaker real income growth. The CPA's downgrade of its 2026 output forecast from +1.7% to −3.3% reflects exactly this split. Meanwhile, the government confirmed this week that a construction jobs plan will be published later this year — a clear signal that workforce shortage, not just demand, is seen as the binding constraint on delivery when the cycle turns.

Practical Steps Now

1. Budget for escalation, not deflation. The assumption that a shrinking market means cheaper tenders is not supported by the data. Cost plans should carry realistic escalation allowances — around 2% near term, consistent with BCIS forecasts — and be re-benchmarked against current tender returns, not last year's.
2. Match the procurement route to the market. Competition is strongest on smaller projects. On larger schemes, expect tier one selectivity and use it: two-stage and early contractor involvement buy the scope, programme and risk testing that single-stage fixed pricing currently delivers expensively, or not at all.
3. Interrogate the cheapest bid. In this market, an outlier-low tender usually signals unpriced escalation or a stretched balance sheet, not a bargain. Compare bidders' escalation assumptions and supply chain reliance before ranking on price.
4. Retest viability with fresh inputs. Funders looking at a −3.3% output forecast will expect appraisals to reflect realistic build cost growth and slower sales or letting assumptions — particularly for schemes outside London and the South East.
5. Move while the window is open. With infrastructure pipelines strengthening and forecasters still expecting output growth of 2–3% from 2027, today's competitive tension in tendering is unlikely to persist indefinitely. Schemes procured into that window will lock in better value than those that wait for a recovery that starts without them.

What This Means

Falling output alongside rising prices is the signature of a market that has shrunk its capacity faster than its demand — and it is precisely the condition in which naive cost planning fails. Clients who treat the downturn as a discount window will be disappointed by tender returns; contractors who chase volume on unfunded risk will add to the insolvency figures. The schemes that perform in this environment are those with honest escalation allowances, a procurement route that matches bidder behaviour, and cost benchmarks refreshed against live market data rather than yesterday's indices.

That is the discipline we apply across our cost management portfolio — and the reason we'd rather re-benchmark a cost plan today than defend an optimistic one at tender return.
