With sharp falls in housing, commercial and civil engineering activity,  the seasonally adjusted S&P Global UK ɫèֱ²¥ Purchasing Managers’ Index registered 40.1 in December 2025, up from 39.4 in November but below the neutral 50.0 value for the 12th successive month.
The December 2025 reading was the second-lowest since May 2020 but was at least not quite as bad as November.
Civil engineering was the weakest-performing category of construction activity in December (index at 32.9), despite recording a softer rate of contraction than in November. Both housing activity (33.5) and commercial construction (42.0) decreased to the greatest extent since May 2020.
Anecdotal evidence suggested that fragile confidence among clients and subdued underlying demand had resulted in lower workloads at the end of the year. Many firms also noted that delayed investment decisions ahead of the budget in November had weighed on their sales pipelines.
December data signalled a sharp decline in total new work across the construction sector. Reduced volumes of new business were recorded in each month of 2025, but the pace of contraction moderated since November.
Despite sluggish demand conditions and a lack of new orders to replace completed projects, the latest survey pointed to a recovery in business optimism at UK construction companies. Around 37% of the survey panel predict a rise in output levels during the year ahead, compared to 20% that forecast a decline. This signalled the highest level of business confidence for five months. A number of firms cited forthcoming new work in the utilities sector, related to investments in water and energy infrastructure. Lower interest rates and an improvement in domestic economic conditions were also reported as factors that could help to boost construction activity over the course of 2026.
Mirroring the trend for business activity in December, construction companies recorded relatively sharp reductions in employment and input buying. However, the rates of decline moderated since November, which was partly attributed to improved projections for workloads in the year ahead.
Tim Moore, economics director at S&P Global Market Intelligence, said: "UK construction companies once again reported challenging business conditions and falling workloads in December, but the speed of the downturn moderated from the five-and-a-half-year record seen in November. Many firms cited subdued demand and fragile client confidence. Despite a lifting of Budget-related uncertainty, delayed spending decisions were still cited as contributing to weak sales pipelines at the close of the year.
"By sector, latest data indicated the fastest reductions in housing and commercial construction since May 2020, while civil engineering was the only segment to signal a slower pace of decline than in the previous month.
"Total new orders nonetheless decreased to a much lesser degree than in November, while business activity expectations for the year ahead rebounded to a five-month high. Some survey respondents attributed greater optimism to projections of rising infrastructure spending, especially in the utilities sector. There were also hopes that lower borrowing costs and easing inflationary pressures could boost demand across the construction sector.
"Supplier performance meanwhile improved for the fifth month running, largely due to lower input buying. This also contributed to a slowdown in purchasing price inflation to its weakest since October 2024."
