The register
The register lists Block Aid Limited in Manchester, Lancs 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).
Companies House lists it as Block Aid UK Limited, number 12381715, incorporated 2019: 6 years of filings behind the name. Registered office: Unit 1 Green Farm, Puxley, Northants, NN12 7QS, NN12 7QS. Its filed activity puts it in public administration. It has traded under other names before, including Block Aid UK (smith & West) Limited, Block Aid Holdings Limited.
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.
