The register
The register lists Lette Ltd 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 Lette Ltd, number 14864500, incorporated 2023: 3 years of filings behind the name. The registered office is at 39/40 St James's Pl., London, SW1A 1NS, SW1A 1NS. Its filed activity puts it in professional and technical services.
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.
