CACI Ltd

Overview

About

CACI Ltd is a data and technology consultancy based at Caci House, Kensington Village, Avonmore Road, London, W14 8TS, in west London. The company was founded in 1975, giving it more than fifty years of operating history, and it employs between 1,001 and 2,000 people, making it by far the largest company on this list by headcount. The verified record does not name an individual chief executive for the UK business. Its published services are web development, AWS, Azure, backup and recovery, cloud migration, and colocation. Its listed vendor partners are Microsoft, Fortinet, and Cisco. It can be contacted on +44 20 7602 6000, and its website is caci.co.uk. The LinkedIn and X profiles on record point to the global CACI corporate accounts rather than UK-only pages. A founding date of 1975 puts the company's origins in the era of mainframe computing, decades before the internet, which means it has adapted through every major wave of business technology since. With 1,001 to 2,000 employees, CACI operates at a completely different scale from the typical managed service provider, with the capacity to staff large, long-running programmes for major organisations. The Kensington Village address is a well-known business campus in west London. The combination of consultancy, data, and managed technology services in one company means clients can get strategy, build, and ongoing operations from the same supplier.

CACI's web development service covers the design and build of websites and web applications for business use. Its AWS and Azure practices cover work on Amazon's and Microsoft's public cloud platforms, from initial setup through to running production workloads. Backup and recovery means scheduled data protection and the ability to restore systems after incidents. Cloud migration covers moving existing systems into AWS or Azure in a planned way, including the assessment of what should move and in what order. Colocation means housing client-owned servers in professional data centres, where power, cooling, physical security, and network connectivity are handled by the facility. Its three listed partners are among the most widely used enterprise vendors: Microsoft for cloud and productivity platforms, Cisco for networking hardware, and Fortinet for network security appliances. For a company of this size, managed services typically sit alongside consulting engagements, so a client might first get help designing a cloud or data platform and then hand its day-to-day operation to the same provider. The contact number +44 20 7602 6000 and the website caci.co.uk are the published routes for reaching the UK business.
