The register
The register lists Intsol Recruitment 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).
Intsol Recruitment Limited is the registered name (Companies House number 07647610), a private limited company on the register since 2011. The registered office is at 1 Kings Avenue, London, N21 3NA, N21 3NA. Its filed activity puts it in recruitment and employment agencies.
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.
