Common questions about Serum Life Sciences Limited
- Is Serum Life Sciences Limited a licensed UK visa sponsor?
- Yes. Serum Life Sciences Limited in London holds a UK sponsor licence and appears on the Home Office register of licensed sponsors, where it has been listed since 2021. That means it is permitted to sponsor eligible workers from overseas, though a licence is permission to sponsor rather than a guarantee that any particular vacancy is open to sponsorship.
- What visa routes can Serum Life Sciences Limited sponsor?
- Serum Life Sciences Limited is licensed for Global Business Mobility: Senior or Specialist Worker and Skilled Worker. Its licence is recorded on the register as "Worker (A rating)" — the rating reflects the Home Office's confidence in the sponsor's compliance record.
- Where is Serum Life Sciences Limited based?
- The register lists Serum Life Sciences Limited at 15 Grosvenor Street, London, United Kingdom, W1K 4QZ. This is the address on the sponsor licence, which is usually the head office — a sponsored role may be based at a different site.
