Housebuilding slump drives deeper UK construction downturn
Britain’s construction sector contracted at a faster pace in October as a sharp slump in housebuilding dragged overall activity lower. The headline S&P Global UK Construction PMI fell to 43.6 in October from 46.1 in September, signalling the steepest decline in output since June and remaining below the neutral 50.0 level that separates expansion from contraction.
The index has now registered below 50.0 for twenty-two consecutive months, underlining a prolonged period of weakness across the sector. The latest reading also came in below economists’ expectations, which had pointed to no change from September.
Residential construction under intense pressure
Housing was the weakest-performing area of construction, with residential activity falling sharply. The sector’s index dropped to 35.1 in October, the lowest level since December 2025 and indicative of a steep decline in housebuilding work.
Construction companies cited rising borrowing costs, low consumer confidence and elevated risk aversion as key factors weighing on new housing projects. They also pointed to broader economic uncertainty as an additional headwind for residential development.
Civil engineering and commercial segments also contract
Civil engineering and commercial construction activity also declined in October, adding to the overall fall in the PMI. Civil engineering recorded an index level of 45.9, while commercial work stood at 46.3, both remaining in contraction territory.
However, the downturn in civil engineering was relatively less severe, with the pace of contraction the slowest since May 2025. Commercial activity showed some resilience, although it eased back from a recent high seen in September.
Costs, confidence and sector outlook
Input cost pressures intensified, with the survey’s index of input prices rising to its highest level since June after a jump of more than 10 points on the month. Firms highlighted fuel surcharges and energy costs as key contributors to higher expenses.
Business optimism weakened, with confidence among construction firms slipping to its lowest point since May. Despite this, some companies reported strong demand for data centre projects and increasing workloads in the energy and utilities sectors, with resilient infrastructure spending helping to limit the downturn in civil engineering.
Construction weak spot contrasts with broader economy
While construction remained in contraction, broader UK private sector activity showed modest improvement. The composite all-sector PMI, combining construction, manufacturing and services, rose to 52.1 in October from 51.5, its strongest reading since February, indicating expansion at the overall economy level even as construction stayed under pressure.
Key Takeaways
- 01The UK construction sector remains a clear weak point in the economy, with October marking nearly two years of continuous contraction.
- 02Housebuilding is bearing the brunt of higher borrowing costs and weak confidence, pulling the wider construction index lower.
- 03Rising input costs and fading business optimism suggest that pressure on margins and investment plans could persist in the near term.
