Revenue: £50.1m (+14%)
Net profit: 1.3%
This Sheffield-based reseller broke through the £50m revenue barrier in its year ending 31 July 2017 on the back of 14 per cent growth. The impact of currency movements stemming from the Brexit referendum squeezed its margins, however, causing net profits to shrink from £997,000 to £654,000. Sister company Millgate Connect, a wireless comms specialist whose numbers are not included in this profile, turned over £4.7m in its year to 31 December 2017.
