Key Findings:

Output levels fall for the third month in a row
Lowest business optimism since October 2023
Input cost inflation highest for 26 months

UK construction companies indicated a sustained downturn in business activity, alongside pressure on margins from sharply rising input costs.

Combined with a drop in new orders, this contributed to the fastest reduction in employment numbers for nearly four-anda-half years.

The headline S&P Global UK Construction Purchasing Managers’ Index™ (PMI®) – a seasonally adjusted index tracking changes in total industry activity – posted 46.4 in March, up from a 57-month low of 44.6 in February but still well below the neutral 50.0 threshold. Lower volumes of construction output have now been recorded for three consecutive months and the latest reading indicated a solid pace of contraction.

Civil engineering (index at 38.8) was the weakest-performing area of activity in March. The sharp decline in output levels was attributed to delayed decision-making on new projects and a generally subdued pipeline of major infrastructure work. The rate of contraction accelerated to its fastest since October 2020.

Residential construction activity declined at a slower pace than in February, but the respective seasonally adjusted index was still well inside negative territory (44.7). Survey respondents typically commented on weak demand conditions, although some suggested that easing borrowing costs had helped to support confidence.

Commercial building (47.4) deceased only moderately in March. That said, the rate of contraction was the fastest since January 2021. Lower business activity was linked to lacklustre UK economic prospects and the impact of rising geopolitical uncertainty on clients’ investment spending.

Sluggish demand conditions contributed to another marked deterioration in construction order books. Lower levels of incoming new work have been recorded throughout 2025 to date. Construction companies often noted a lack of sales enquiries and greater competition for new work.

Lower workloads, elevated interest rates and worries about the broader economic outlook continued to weigh on business activity expectations in March. Confidence across the construction sector slipped to its lowest since October 2023. Some firms nonetheless noted positive sentiment regarding the outlook for demand across the renewable energy sector and hopes of a turnaround in infrastructure workloads.

Mirroring the trends for output and new work, latest survey data indicated a reduction in staffing numbers for the third consecutive month. The rate of job shedding was the steepest since October 2020. Subcontractor usage also decreased at a solid pace in March, while construction companies reported further cutbacks to their input buying in response to lower workloads.

Finally, higher payroll costs due to forthcoming rises in National Insurance contributions and the National Minimum Wage continued to push up average cost burdens. The overall rate of input price inflation accelerated to its strongest since January 2023.

Tim Moore, Economics Director at S&P Global Market Intelligence, said, “March data highlighted a challenging month for UK construction companies as sharply reduced order volumes continued to weigh on overall workloads.

“Civil engineering experienced the biggest setback as activity decreased to the greatest extent since October 2020. Survey respondents commented on subdued sales pipelines and a subsequent lack of infrastructure work to replace completed projects.

“Commercial work also saw a headwind from delayed decision-making on major projects, largely due to worries about the impact of rising global economic uncertainty. The downturn in residential construction activity nonetheless eased since February, providing a source of encouragement despite ongoing reports of sluggish demand conditions.

“Construction companies remained cautious about their year ahead growth prospects, as fewer sales conversions and a third successive monthly reduction in total new work hit confidence levels. Overall business optimism slipped to its lowest since October 2023.

“A lack of new projects, alongside pressure on margins from rising payroll costs, led to hiring freezes and the non-replacement of departing staff in March. The net result was the fastest pace of job shedding across the construction sector for nearly four-and-a-half years.”
