ISG Ltd (formerly Interior Services Group) is a privately-owned, London-based construction company that employed around 3,000 people, mainly in the UK, mainland Europe and the Middle East. In terms of turnover, at one point it was the sixth biggest contractor in the UK.
It was founded in 1989 as Stanhope Interiors; it was renamed Interior plc following a management buyout during 1995. Two years later, the business, which was then trading as Interior Services Group, was floated on the Alternative Investment Market of the London Stock Exchange. It expanded rapidly during the late 1990s and early 2000s, branching into construction management and facilities management. During the mid 2000s, the firm opted to reduce its presence in some markets, such as France and Germany, while embarking on an spree of acquisitions, including Propencity, Commtech Asia, and Pearce Group.
Following the start of the Great Recession in the late 2000s, both orders and profits at the company dipped sharply. In response, ISG sought out new business on the still-growing international market. During March 2016, ISG was taken private by the US-based firm Cathexis (the investment vehicle of Texan billionaire William Harrison). During the early 2020s, the company's fiscal condition was impacted by the COVID-19 pandemic. In September 2024, following months of concerns about its finances and a stalled sale of the group, eight ISG businesses entered voluntary administration; the situation has been called the biggest collapse in Britain's construction sector 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 immediately made redundant.
