British manufacturing exceeded expectations last month as growth accelerated to hit a four-month high, according to a closely watched survey.

IHS Markit’s UK manufacturing purchasing managers' index (PMI) jumped to 56.9 last month, higher than the 55 that had been expected and above the 55.1 reported in July. Any number above 50 suggests growth in the sector’s output.

The survey found “broad-based expansion” across all products, and production rose at the steepest pace in seven months, underpinned by more work received, especially in Europe, the USA, China and Australia.

However, while the trend in new export business remained “robust”, most of the new work was won domestically.

“Although the rate of improvement in foreign demand eased from July’s near-record high, it remained among the strongest seen since new export orders data were first collected in January 1996,” IHS Markit found.

A stronger manufacturing sector also led to more jobs, with the rate of increase in employment the fastest since June 2014.
