Construction Sector Plummets Unexpectedly Ahead of Budget Announcement

The UK construction sector has experienced a surprising and sharp decline in activity, marking the fastest fall in over five years. This downturn, recorded in October, precedes the upcoming November Budget and has raised concerns among economists, particularly due to prolonged speculation about potential tax hikes.

Key Takeaways

UK construction activity saw its steepest fall since May 2020.
The Purchasing Managers’ Index (PMI) dropped to 44.1 in October, below economists’ expectations.
This marks the tenth consecutive month of contraction, the longest streak since the 2008 financial crisis.
Client risk aversion and delayed decision-making are cited as primary reasons for reduced workloads.
Job shedding in the sector accelerated to its fastest rate in over five years.

Economic Downturn Deepens

New figures from the S&P Global UK construction purchasing managers’ index (PMI) revealed a significant drop to 44.1 in October, down from 46.2 in September. This figure fell short of the consensus forecast of 46.7, which had anticipated a rise in activity. The sustained period below the neutral 50-point threshold signifies a continuous contraction in the sector, a trend that has persisted for ten months, the longest stretch since the 2008 financial crisis.

Factors Driving the Decline

Experts attribute the slump to a combination of factors, including heightened fiscal worries and persistent rumours of tax increases in the forthcoming Budget. Tim Moore, economics director at S&P Global Market Intelligence, noted that “prolonged weakening of order books” throughout 2025 has led to the sharpest decline in business activity. Clients’ risk aversion and a delay in decision-making have resulted in fewer new projects being initiated. Furthermore, subdued demand, exacerbated by political and economic uncertainty, has led to the most significant drop in input buying since May 2020.

Impact on Employment and GDP

The challenging conditions have also impacted employment, with construction firms shedding jobs at the fastest rate in over five years during October. This includes a reduction in hiring new staff and fewer subcontractors being engaged. Economists at Pantheon Macroeconomics have warned that this downturn in construction activity poses downside risks to current forecasts for fourth-quarter gross domestic product (GDP) growth. Elliott Jordan-Doak, senior UK economist at Pantheon, highlighted that the plummeting PMI suggests projects are being postponed in anticipation of the Budget, underscoring the consequences of prolonged speculation about tax hikes.

Glimmers of Hope

Despite the overall negative trend, some positive indicators emerged from the survey. Build cost inflation increased at its slowest pace in a year, and overall optimism within the sector edged up to its highest level since July. This improved sentiment is partly attributed to the prospect of interest rate cuts, which could potentially boost future demand projections.
