UK manufacturers have experienced a weakening of output growth and a softening of their order books, a survey shows.

A rounded balance of one per cent of manufacturers consider their total order books to be below-normal, according to the Confederation of British Industry’s latest monthly survey. This balance is arrived at by subtracting the proportion reporting above-normal order books from that declaring a worse-than-usual position.

In the previous monthly survey, a net 7% of manufacturers had reported above-normal order books.

A balance of 5% of manufacturers described their export order books as above-normal in the latest survey. This is a deterioration from last month’s survey, in which a balance of 9% of manufacturers reported above-normal export order books.

In the latest survey, a balance of 11% of manufacturers reported a rise in output volumes over the latest three months. In August’s survey, a net 21% of companies in the sector had recorded an increase in output volumes over a three-month timeframe.

Anna Leach, head of economic intelligence at the CBI, said: “While manufacturing order books remain strong and output is still growing, Brexit uncertainty continues to cloud the outlook.

“Heightened fears of a ‘no deal’ Brexit scenario have prompted some firms to move publicly from contingency planning to action.”

She added: “Efforts on all sides must be geared towards securing the withdrawal agreement and –crucially – the transition period. This will provide temporary but essential relief for businesses of all sizes and sectors.”

The CBI said: “We expect UK manufacturers to continue benefiting from healthy external demand and a lower sterling exchange rate, but overall economic growth is expected to remain subdued, reflecting weak household income growth and the drag on investment from Brexit uncertainty.”

Tom Crotty, group director at Ineos and chair of the CBI’s manufacturing council, said: “In the coming months, manufacturers will be looking to the Government to protect the frictionless trade with the EU that they need to thrive.”
