Interserve

Interserve is a British construction and support services business based in Reading, Berkshire, which went into administration in 2019 and which is expected to be wound up in 2024. At that time, the group generated revenue of £2.2 billion and had a workforce of 34,721 people.The company was founded in 1884 as the London and Tilbury Lighterage Company Limited. From 1991, it was known as Tilbury Douglas following a merger with RM Douglas, but in 2001 it rebranded as Interserve plc. The name change partly reflected a shift in focus during the 1990s towards maintenance and facilities management services sectors, and this continued in the 2000s, buoyed by further acquisitions.

However, financial issues including problem contracts in Interserve's energy-from-waste business led to profit warnings in 2017. The company was forced to restructure and refinance in March 2018.
