2026.09.2308:30:00UTC+00UK S&P Global Composite PMI Eases to 51.7 in September, Signalling Moderation in Private-Sector Growth

The United Kingdom’s private-sector growth slowed in September, as the S&P Global Composite PMI edged down to 51.7 from 52.5 in August 2026. While still above the 50.0 threshold that separates expansion from contraction, the latest reading points to a moderation in overall economic momentum.

The September figure, released on 23 September 2026, suggests that activity across both manufacturing and services continued to grow, but at a weaker pace than in the previous month. The easing in the composite index may indicate that demand conditions are becoming more cautious, with businesses potentially facing a more challenging operating environment as the year progresses.

Investors and policymakers are likely to monitor upcoming PMI releases closely for signs of whether this slowdown is temporary or the start of a more sustained loss of momentum in the UK economy. For now, the data still depict an expanding private sector, albeit one growing with reduced vigor compared with late summer.
