Common questions about Rio ESG Ltd
- Is Rio ESG Ltd a licensed UK visa sponsor?
- Yes. Rio ESG Ltd in London holds a UK sponsor licence and appears on the Home Office register of licensed sponsors, where it has been listed since 2022. 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 Rio ESG Ltd sponsor?
- Rio ESG Ltd is licensed for 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 Rio ESG Ltd based?
- The register lists Rio ESG Ltd at Old Street Works Level 1, 197 City Road, London, England, EC1V 1JN. This is the address on the sponsor licence, which is usually the head office — a sponsored role may be based at a different site.
- How current is this information?
- This page is built from the UK Home Office register of licensed sponsors. We resync the register daily and keep a dated history of every addition and removal, alongside Companies House records for company number 06863577. The register itself is the authoritative source — always confirm on GOV.UK before relying on a licence status.
