Snook said he placed great emphasis on retaining staff because of the skills crisis facing the industry. He said this was a crucial factor in the success of his business.
He said: "We think Rok is an exciting place to work and we are trying to create an environment that sets us aside from other businesses as a place where people want to work."
Rok chairman Bob Carlton-Porter said the labour force was ageing and recruitment and training had failed to keep pace. He said he expected to see continued consolidation in the sector, with financially strong groups that could provide good training and opportunities taking the lead.

Carlton-Porter said Rok was well placed financially to take advantage of acquisition opportunities that might arise.
He said: "The UK building economy remains strong, especially in the regions. It's buoyed by continuing demand from the public sector in health, education and housing."
