Chief executive Paul Cossell, 55, suspended work in March at all construction sites where social distancing measures could not be followed. At the time, ISG was helping to build Edinburgh’s first single-malt whisky distillery for 90 years and won a contract to construct a new innovation centre for media giant Sky in west London. Last year, ISG delivered data centre schemes worth £605m across the world. The fit-out and construction specialist operates across 24 countries and is owned by Cathexis, an American investment firm.
