The register
The register lists Nichebox UK Limited in London as a licensed sponsor on Skilled Worker, an entry that goes back to at least 2026. The register records its rating as Worker (A rating).
Companies House lists it as Nichebox UK Limited, number 01384942, incorporated 1978: 48 years of filings behind the name. The registered office is at 32 Brook Street, London, W1K 5DH, W1K 5DH. Its filed activity puts it in professional and technical services. It has traded under other names before, including Clive Christian Limited, Clive Christian PLC.
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.
