Last updated August 28, 2026
Overview
Oracle Corporation UK Limited is the United Kingdom operating company of Oracle Corporation, the United States-based enterprise technology group. The legal entity is distinct from the publicly traded parent company: it is registered in the UK as a private limited company and does not have its own stock-market ticker. Companies House records identify the company by number 01782505, with a registered office at Oracle Parkway, Thames Valley Park, Reading, Berkshire. The company was incorporated on 12 January 1984 under the name Sierradata Limited and changed its name to Oracle Corporation UK Limited on 3 February 1984. The subsidiary’s activities cover the principal areas in which Oracle serves UK customers. Its registered business classifications include software development, information-technology consultancy, computer-facilities management, and data processing, hosting and related activities. In practical terms, the UK operation supports the sale, implementation, operation and servicing of Oracle technologies for businesses, public-sector bodies and other organisations. The product and service scope associated with Oracle UK includes database management, cloud infrastructure, enterprise applications, data warehousing, customer relationship management, supply-chain management, technical consulting and managed or hosted computing services. Oracle’s UK business operates within the wider Oracle group rather than as an independent product brand. Oracle Corporation’s portfolio spans database and middleware technologies, infrastructure and platform cloud services, software-as-a-service applications, analytics, security, hardware and professional services. The UK subsidiary provides a local commercial, consulting, support and operational presence for these offerings. Reference material identifies customers and markets including BT and the UK National Health Service, although no current customer revenue split or independently reported UK financial figure is established here. The company’s principal registered base is in Reading’s Thames Valley Park technology cluster. Reference material also describes Oracle UK activity through offices or operations in England, Scotland and Ireland. Its market role is therefore best understood as a national and regional enterprise-technology subsidiary serving large organisations, government and other institutional users, while relying on Oracle Corporation for global product development, corporate strategy, financing and brand ownership. Oracle Corporation UK Limited remains active according to Companies House. Its available public filing profile identifies it as a private company and records recent statutory filing dates, but the supplied sources do not establish a reliable current workforce figure, revenue figure, standalone valuation, or detailed breakdown of its cloud activities. The entry should consequently be read as a profile of the UK legal operating company, not as a substitute for the global Oracle Corporation encyclopedia entry.
History
Oracle Corporation UK Limited was incorporated in the United Kingdom on 12 January 1984. The entity initially traded as Sierradata Limited, but that name was used only briefly; the company changed to Oracle Corporation UK Limited on 3 February 1984. This early formation created a UK legal and operating platform for the Oracle business, whose global parent had been established in the United States in 1977. Over time, Oracle UK developed beyond a narrow software-sales function. Its recorded corporate activities encompass software development, information-technology consultancy, computer-facilities management, and data processing and hosting. These classifications reflect the broader evolution of Oracle’s enterprise business: from a database-centred technology supplier into a provider of integrated databases, middleware, cloud infrastructure, business applications, analytics and professional services. The UK subsidiary’s role is to bring that wider portfolio to customers in its local market. Oracle UK has served commercial and public-sector organisations, with reference material identifying BT and the UK National Health Service among its customers. Its work can include licensing and subscription sales, cloud adoption, application and database implementation, technical advice, systems integration, infrastructure operation and customer support. The company has been associated with activity from offices or operations in England, Scotland and Ireland, while its registered office is at Oracle Parkway in Reading, Berkshire. Oracle Corporation’s international expansion has included substantial movement into enterprise applications and cloud computing, supported by acquisitions such as PeopleSoft, Siebel Systems, Hyperion, Sun Microsystems, NetSuite and Cerner. Those transactions belong to the parent group, not necessarily to the UK legal entity, but they have expanded the range of technologies that Oracle UK can market and support. The same distinction applies to Oracle’s public listing: Oracle Corporation is publicly traded, whereas Oracle Corporation UK Limited is a private UK subsidiary and has no separate ticker. Companies House currently records the UK company as active. Its public profile confirms the Reading registered office, its private-company status, incorporation history and technology-related SIC classifications. The supplied sources do not provide a sufficiently reliable standalone chronology of Oracle UK’s product launches, revenue, staffing, campaigns or former leadership to support more detailed claims. The company’s documented history is therefore primarily one of continuity as Oracle’s UK corporate, commercial and service platform.
