Ambulance builder O&H Vehicle Technology has completed a management buyout from private equity owner Endless. Managing director Oliver North and entrepreneur Ken Davy have led the buyout, having worked together to grow fire fighting equipment supplier North Fire prior to its acquisition in 2014. O&H is responsible for the majority of ambulances on Yorkshire’s roads. In 2018, Yorkshire Ambulance Service (YAS) placed an order for over 300 new units.
