The register
The register lists Accept & Proceed 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).
Companies House lists it as Accept & Proceed Limited, number 06225749, incorporated 2007: 19 years of filings behind the name. The registered office is at Asm House, 103a Keymer Road, Hassocks, West Sussex, BN6 8QL, BN6 8QL. Its filed activity puts it in professional and technical services.
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.
