How to Sponsor an Engineering Professional Under SOC 2129

Step-by-Step Sponsorship Process

1. Check that your organisation holds a valid sponsor licence for the Skilled Worker route.
2. Confirm the role qualifies under SOC Code 2129 and meets skill and salary requirements.
3. Carry out a Resident Labour Market Test if applicable, or confirm an exemption applies.

5. Ensure the candidate applies for their Skilled Worker visa before beginning work.
6. Conduct right to work checks and maintain accurate records throughout employment.

Applying for a Sponsor Licence

If your business does not yet hold a sponsor licence, you must apply to the Home Office before you can assign a Certificate of Sponsorship. The application requires evidence that your organisation is genuine, operating legally, and has appropriate HR systems in place. You can find full guidance on the gov.uk sponsor licence application page.
