Revenue: £72.8m (+23%)
Net profit: 2.7%
Centerprise founder Rafi Razzak told us last December that he would gradually hand over control of the company to newly appointed chief executive Jeremy Nash after spending 30 years at the firm's helm. Nash is a former RAF officer, which plays to Centerprise's heritage in the defence and public sector verticals. For its year to 31 August 2017, Centerprise Group saw revenue vault 23 per cent, which it attributed partly to an investment in its business continuity and disaster recovery business.
