Holding a sponsor licence isn't a one-off application — it's a standing set of legal duties that the Home Office audits without warning. The duties are exactly the same whether you sponsor two people or two hundred. Here is the whole obligation, as a checklist you can actually run.
1. Report worker changes — within 10 working days
Sponsor guidance Part 3 (version 05/26, 20 May 2026) requires reports "by no later than 10 working days after the relevant change or event has occurred" [^1] for, among others:
- a worker who doesn't start within 28 days of their CoS start date;
- absence without permission for more than 10 consecutive working days;
- employment ending earlier than the CoS says (resignation, dismissal, anything);
- a worker's salary or pay being reduced;
- significant changes to the role, duties or work location — including a move to fully-remote "contractual home worker" status (routine hybrid patterns don't need a report) [^2].
Working days exclude weekends and England & Wales bank holidays — a deadline that crosses the Christmas cluster is shorter than it looks.
2. Report organisation changes — within 20 working days
Changes to your organisation — registered or trading address, Key Personnel (Authorising Officer, Key Contact, Level 1 users), ownership, mergers and takeovers — must be reported "within 20 working days of the relevant event occurring" [^3]. Ownership and structural changes can require a fresh licence application on tight timescales, not just a report: take advice the day the deal becomes real.
3. Keep the Appendix D file — per worker and organisation-wide
Appendix D ("Keeping records for sponsorship", current edition 20 May 2026 [^4]) is the list an inspector works through. Per worker: right-to-work evidence, the employment contract, current contact details with a history of changes, absence records, salary/payslip evidence, a job description matching the CoS, qualifications, and recruitment evidence (adverts, shortlists, interview notes). Organisation-wide: documented HR processes, premises evidence and a hierarchy chart. If you can't produce an item on demand, it might as well not exist.
4. Right-to-work checks — before day one, and again before permission expires
Every worker needs a compliant initial check with the date recorded, and a diarised follow-up before time-limited permission expires. Getting this wrong risks a civil penalty of up to £60,000 per illegal worker [^5] — the statutory excuse from a proper check is the only protection.
5. Keep key personnel real
Your Authorising Officer, Key Contact and Level 1 users must be current, contactable and aware of their duties. A Level 1 user who left six months ago is a silent compliance failure — review annually.
6. The salary floor moves — watch it
The general Skilled Worker threshold is currently £41,700 (or the job's going rate, whichever is higher; new-entrant floor £33,400) [^6], and the occupation going rates were revised as recently as 1 July 2026 [^7]. Any worker within a few thousand pounds of a threshold needs checking every time the rules change.
Run it monthly, prove it annually
The sponsors who sail through visits are the ones with a standing routine: a monthly sweep of the six duties above, and an annual mock audit that assembles the whole file the way an inspector would ask for it. That's the entire reason SponsorFort exists — see where you stand in two minutes.
