The Hull business said it will pay 1.97p per share to investors.
It reported a three per cent rise in group revenues to £177.9m in the six months to September 30.
Earnings before interest, tax, debt and amortisation also rose 3 per cent to £37.2m.
Bill Halbert, chief executive, said: “The group has delivered improved performance across all target segments.
“The results are clear evidence of the potential of our strategy and of the level of opportunity we have in our chosen markets.
“Our focus on generating targeted organic revenue growth, coupled with further steps to simplify the operating structure of the business, places us in a strong position to create a single, unified and simplified business by the end of this financial year.
“Consistent with our prior commitment of a minimum of 10 per cent year on year growth, the board confirms its intention to pay an interim dividend of 1.97 pence per share.”
