John Doyle Group has posted a 6% drop in comparable turnover for the year ended 31 December 2007.
The figure of £168m was down on £178.1m for the previous year, which saw a management buyout in May.
Comparable pre-tax profit was down by a third from £2.4m to £1.6m after what Richard Clancy, its finance director, said had been “an exceptionally good 2006”.
He said: “We are not yet seeing the credit crunch have any major impact on schemes.”
Although Clancy said the company, which has been renamed Doyle Group, was aiming to exceed £200m turnover in 2008, he conceded there was more uncertainty beyond then.
“There’s a nervousness but it’s the same for everyone. The worry is that the larger schemes will be postponed.”
