ISG Ltd (formerly Interior Services Group) is a privately-owned, London, England based construction company that employed around 3,000 people, mainly in the UK, mainland Europe and the Middle East. By turnover, it was the sixth biggest contractor in the UK.
In September 2024, following months of concerns about its finances and a stalled sale of the group, eight ISG businesses entered voluntary administration, in UK construction's biggest collapse since Carillion in 2018. At the time of its collapse, ISG was working on 69 UK public sector projects worth at least £1.84bn, and owed its supply chain over £700m. Around 2,200 ISG UK employees were made immediately redundant.
