The register
The register lists Hirsh Limited in London as a licensed sponsor on Skilled Worker, an entry that goes back to at least 2026. Its rating on the register is Worker (A rating).
Hirsh Limited is the registered name (Companies House number 01495932), a private limited company on the register since 1980. The registered office is at 46 Conduit Street, London, W1S 2YW, W1S 2YW. Its filed activity puts it in manufacturing and engineering. It has traded under other names before, including Anthony Hirsh Fine Jewels Limited.
What the licence tells a candidate is that the door is not locked. Whether it is open this month is a question for Hirsh Limited's own careers page and the job boards, and the answer changes with the season and the order book.
