Sponsor maintenance certification letter
For sponsors who certify maintenance on the CoS. Keep this factual and aligned with the Certificate of Sponsorship and HR records. Avoid quoting changing thresholds; the application will reference current rules.
When to use this
- Skilled Worker (or similar work routes) where the sponsor certifies maintenance on the CoS.
- To provide a clear HR contact and confirm employment intent and start date.
Good practice
- Put this on letterhead or include full company details and a named authorised officer.
- Keep statements consistent with the CoS details (role, location, start date).
- Avoid quoting specific monetary thresholds — they change. Refer to “current sponsor guidance”.
Common pitfalls
- Mismatch with CoS: ensure title, location, start date and any salary figure match the CoS.
- Vague contact: include a named HR/authorised officer with an email (and phone).
- Over-committing: keep the promise aligned to what the CoS certification means in guidance.
