Common questions about Diffblue Ltd

Is Diffblue Ltd a licensed UK visa sponsor?
Yes. Diffblue Ltd in Oxford holds a UK sponsor licence and appears on the Home Office register of licensed sponsors, where it has been listed since 2019. 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 Diffblue Ltd sponsor?
Diffblue 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 Diffblue Ltd based?
The register lists Diffblue Ltd at Ramsey House, 10 St. Ebbes Street, Oxford, England, OX1 1PT. This is the address on the sponsor licence, which is usually the head office — a sponsored role may be based at a different site.
