ICL Locations
ICL was concentrated in the United Kingdom, with its corporate headquarters in Putney.
At the time of the original merger, the company inherited extensive engineering and manufacturing facilities in West Gorton and Stevenage from ICT, and from English Electric in Kidsgrove (Staffordshire) and Winsford (Cheshire). The company had a large research, operating system and superstructure development and support centre in Bracknell, another smaller one at Dalkeith in Scotland, application development in Reading, and training centres at Moor Hall (Cookham), Beaumont College (Old Windsor) (sales, support and software) and Letchworth (Hertfordshire) (manufacturing & field engineering). The company also had manufacturing facilities in a former textile mill in Dukinfield and a purpose built factory at Ashton-under-Lyne.
For some years ICL maintained a training and presentation facility for senior management at Hedsor House, near Taplow, Berkshire.
Outside the UK, ICL's offices around the world were mainly sales and marketing operations, with some application development for the local market. The exceptions were development and manufacturing sites arising from acquisitions, such as Utica in the United States from the Singer merger, and a variety of former Nokia Data sites in Sweden and Finland.
ICL and its customers often referred to these locations by the Site Code, especially where multiple sites may exist in a town, with for instance with the Putney Headquarters being LON11 (London 11), the training college at Beaumont being WSR01 (Windsor 01) and the southern System Support Centre (SCC) at Bracknell being BRA05 (Bracknell 05).
