The Group also announced a £2bn order book for the six months ending 31 January 2010, up from £1.9bn in July last year.
It said bidding opportunities had increased as local authorities look to outsource work to the private sector.
Richard Cuthbert, chief executive added: “The business has regained momentum and once again we can look forward with confidence.”
But the ownership of the group hangs in the balance following a takeover bid from industrial giant VT Group.
Cuthbert recently described VT Group’s offer of 260p per share as hostile and opportunistic.
Analysts expect the company to post pre-tax profit of £38.7m for the year to 31 July, down on £40.1m the previous year.
