The register lists Aufgabe Limited in Northampton 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 Aufgabe Limited, number 12034223, incorporated 2019: 7 years of filings behind the name. The registered office is at C/O Aardvark Accounting 1 Cedar Office Park, Cobham Road, Wimborne, BH21 7SB, BH21 7SB. Its filed activity puts it in it, software and media.
What the licence tells a candidate is that the door is not locked. Whether it is open this month is a question for Aufgabe Limited's own careers page and the job boards, and the answer changes with the season and the order book.
