Contractor's maintenance division helps drive turnover 12% as 2005 acqusitions bed in.

Contractor ROK has revealed record results for 2005, with a 38% growth in pre-tax profit to £16.1m and a healthy 12% hike in turnover to £555.8m.

The firm cashed in on a number of framework agreements, worth a total of £1.1bn, and a confirmed order book of £330m.

Rok's results were also helped by rapid growth in its maintenance division, where revenue grew 78% in the year to £48.2m.

The year was also marked by the acquisitions of social housing provider Durose & Gourlay, Lincolnshire-based Topcon Building & Contracting and contractor Lemmeleg in Yorkshire.

Rok chairman Stephen Pettit said: "2005 has been another successful year for the group with revenue, profit before tax, operating margins and earnings per share all at record levels.

"This has been particularly pleasing considering the scale of the investment we have been making in our maintenance operations which have grown substantially over last year.'

"We describe this phase for Rok as 'the end of the beginning'. The strategy has been tested on a larger scale, the executive team is in place and the opportunities for further growth are significant. We are confident that 2006 should be another year of good progress."
