ISG, one of the UK’s largest privately held construction firms, defied turbulence in the sector following the collapse of Carillion to post a dramatic surge in revenues and profits.
The company, which specialises in office and shop fit-outs and complex buildings such as science labs, made £27m in pre-tax profits in 2018, up from £9m the year before, as sales rocketed 30% to a record £2.3bn.
Its strong performance contrasts with others in the sector, including Kier Group and Interserve, which have run into trouble in the past 18 months.
