A newly incorporated UK company can apply for a sponsor licence. The current sponsor guidance does not prescribe a minimum period for which an ordinary Skilled Worker sponsor must have traded. It expressly identifies an organisation operating or trading in the UK for less than 18 months as a start up and imposes a specific requirement for evidence of a qualifying UK corporate or business bank account.
That does not mean incorporation is enough. Part 1 of the sponsor guidance requires the applicant to be a genuine organisation operating or trading lawfully in the UK. It must also be capable of performing the sponsor duties, have suitable key personnel and be able and intend to offer an eligible role. For a young business, those propositions are closely connected because there may be little historic evidence from which the Home Office can test them.
The application should therefore be treated as an evidence exercise about the present business, not a prediction that trading will eventually become substantial. Banking, customers, contracts, regulation, premises, people, systems, funding and the proposed job should tell one coherent story about an operating employer with a real vacancy.
