The register
The register lists OYNB 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).
Companies House lists it as Oynb Limited, number 09626599, incorporated 2015: 11 years of filings behind the name. The registered office is at C/O Opus Restructuring Llp 1 Radian Court, Knowlhill, Milton Keynes, MK5 8PJ, MK5 8PJ. Its filed activity puts it in other services.
What the licence tells a candidate is that the door is not locked. Whether it is open this month is a question for OYNB Limited's own careers page and the job boards, and the answer changes with the season and the order book.
