The register
Mgac LLP is licensed to sponsor on Global Business Mobility: Senior or Specialist Worker and Skilled Worker. Its entry on the register dates back to at least 2026, and the organisation is based in London. The register records its rating as Worker (A rating).
Companies House lists it as Mgac LLP, number OC309255, incorporated 2004: 22 years of filings behind the name. The registered office is at The Warehouse, One Crown Place, London, EC2A 4EF, EC2A 4EF. It has traded under other names before, including Robinson Low Francis LLP.
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.
