The company operates in continental Europe, the Middle East, the Asia Pacific region, including Australia and Hong Kong, and North America.

The company began providing technical and engineering services to the British War Office during the Second World War. During the Cold War era, it specialised in the provision of defense systems engineering and facilities management services, including the maintenance of sonar, early warning radar and satellite systems. Following a management buyout, the firm changed to the name Serco in 1987 and was listed on the London Stock Exchange one year later. The company was restructured during the 1980s, reorientated itself towards services beyond engineering, and expanded its presence globally. Wikipedia
