Starting life as a lines and minutes business in 2004, today Focus Group's portfolio spans telecoms, IT, data and energy. A nine per cent revenue jump in its year to 30 November 2018 was driven by organic growth and the contribution from August 2018 acquisitions Calibre Networks and Calibre Telecoms. With support from HSBC, Focus has coughed up £12m for three further acquisitions since its year end, and in July moved into a new 25,000 sq ft HQ in Shoreham, West Sussex.
