The survey for March showed that businesses reined in their expectations for the coming year in light of uncertainty over the long term performance of the stock market and slower manufacturing growth.
The balance - the percentage of firms expecting higher activity in the next 12 months minus the percentage of firms with lower expectations - fell by 10 points from 66% in February to 56% in March.
Business and financial services firms were most shaken by the stock market performance, predicting this was a precursor for slower global economic growth and demand for their services. This was reflected in the balance of services firms expecting higher rather than lower activity, which dropped 27 points to 52% in March.
Despite the drop in confidence in their own activity, predictions for the UK economy as a whole remained strong. The balance of firms more rather than less optimistic rose by 1 point in March to 29%, well above the survey average of 17%.
Trevor Williams, chief economist at Lloyds TSB Corporate Markets, said: "The unpredictable stock market performance this month has forced UK firms to take a sense check on their activity expectations for the coming year. This looks like it will be just a blip rather than a sustained trough in confidence because underlying UK economic conditions remain strong."
