The register
The register lists Service to the Aged 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).
At Companies House the business is Service To the Aged (company number 02580196), a company limited by guarantee incorporated in 1991, 35 years ago. The registered office is at New Burlington House, 1075 Finchley Road, London, NW11 0PU, NW11 0PU. Its filed activity puts it in social care and care homes.
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.
