The register
IBM UK Ltd is licensed to sponsor on Global Business Mobility: Senior or Specialist Worker and Skilled Worker. Its entry on the register dates back to at least 2026, and the organisation is based in Winchester, Hampshire. The register records its rating as Worker (A rating).
Companies House lists it as IBM Limited, number 01503908, incorporated 1980: 46 years of filings behind the name. The registered office is at Building C Ibm Hursley Office, Hursley Park Road, Winchester, Hampshire, SO21 2JN, SO21 2JN. It has traded under other names before, including LS3 Limited.
A licence says an organisation may sponsor; it does not say it is hiring today. The way to find out is the same as for any employer: the careers page, the job boards, and a direct approach with a UK-style CV that says early that sponsorship would be needed.
