The register
The register lists M & R 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 M & R Limited, number 06163545, incorporated 2007: 19 years of filings behind the name. Registered office: 348 Coombe Lane, London, SW20 0RL, SW20 0RL. By its SIC codes the business is in retail.
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.
