How to Withdraw a Certificate of Sponsorship (CoS) in the UK? HR guide

What Does It Mean to Withdraw a CoS?

Withdrawing a CoS means cancelling it in the Sponsor Management System (SMS) before it results in a granted visa. There are two scenarios where this applies: 

• CoS assigned, visa not yet applied for, the worker holds a CoS reference number but has not yet submitted their visa application to UKVI.
• CoS assigned, visa application already submitted, the worker has used the CoS reference in a live application. This is significantly more complex and requires UKVI notification.

Once CoS is withdrawn,

• The CoS reference number is cancelled and cannot be reused. 
• The withdrawal counts against your annual allocation and the £525 fee is not refunded.

CoS withdrawal in the scenario where CoS is assigned and visa application already submitted, carries real risk to the worker's immigration status and should not be actioned without specialist advice.

7 Valid Reasons to Withdraw a CoS

A Certificate of Sponsorship (CoS) can only be withdrawn before the worker submits their visa application. If any of the following scenarios occur, cancel the CoS in the SMS portal immediately.

• Rescinded Job Offer: The role is eliminated or the offer is canceled before the worker applies.
• Redundancy or Restructure: A company re-org eliminates the position. Ensure you document the business reason internally for your files.
• Candidate Backed Out: The worker declines the role or withdraws their acceptance after the CoS is generated.
• Unfixable CoS Errors: Major mistakes (such as an incorrect SOC code or salary tier) that cannot be fixed with a sponsor note. You must withdraw the CoS and issue a fresh one.
• Failed Background Checks: The candidate fails mandatory pre-employment vetting, references, or background checks. Keep these failed results in your Appendix D compliance files.
• Expiry Date Missed: The candidate fails to submit their visa application within the strict 3-month validity window after CoS assignment.
• Internal Hiring Freeze: A company-wide freeze makes the hire impossible. The Home Office expects to see a clear, documented business rationale for this during audits.

Critical Situations Where You Cannot Withdraw a CoS

When You CANNOT Withdraw a CoS

A CoS can only be canceled before a visa decision is made. You cannot withdraw a CoS if:

• The visa has already been granted.
• The worker has entered the UK.
• The employee has started working.

Any changes to their employment status must go through the SMS reporting route.

What The HR Must Do Instead

• Use SMS Reporting: If an employment relationship ends after visa approval, notify the Home Office via the "Report new activity" section in the SMS portal. This triggers the correct visa curtailment process.
• Respect the 10-Day Window: You must report a departure or contract termination within 10 working days of the employee's last day.  

⚠️ The Compliance Risk: Attempting to "withdraw" a CoS for an active or departed employee leaves a major gap in your SMS records. Home Office inspectors actively look for these reporting mismatches during audits.

How to Withdraw a CoS: Step-by-Step

Step 1: Log into the SMS

Only Level 1 and Level 2 Users can action a CoS withdrawal. Level 1 Users have full licence-level access; Level 2 Users can manage CoS tasks but not licence settings. Log in at the Home Office SMS portal using your individual credentials, shared logins are a compliance violation.

Step 2: Check the CoS status before acting

Locate the CoS under 'Manage live CoS' in the SMS dashboard. Check the status: assigned (not yet used in an application), used (submitted with a visa application), or expired. Acting without checking status first can create irreversible compliance issues, particularly if the application is already live with UKVI.

Step 3: Initiate the withdrawal

Under 'Sponsorship duties' → 'Manage live CoS', locate the relevant CoS record. Select 'Withdraw CoS' and confirm. The SMS will generate a confirmation. Save a screenshot or record the confirmation timestamp for your Appendix D file.

Step 4: Notify the worker

You have a legal and ethical obligation to inform the worker promptly. Communicate clearly: what has happened, why, and what it means for their visa process. If they have already submitted an application using this CoS, advise them to seek immigration advice immediately, they may need to withdraw or pause their application. Document your notification in writing and retain it in your Appendix D compliance records.

Step 5: Update your internal records

Remove the CoS from your active sponsorship tracking log, update your HR system, and retain all withdrawal documentation. The Home Office recommends keeping withdrawal records for at least one year after the event, longer if there is any associated compliance query.

Step 6: Assess whether a new CoS is needed

If the same role is being re-offered, whether to the same worker or a new candidate, a fresh Certificate of Sponsorship must be assigned. The withdrawn CoS cannot be reused. Budget for the £525 fee again; there is no waiver or credit for a previously withdrawn CoS.

Impact of CoS Withdrawal on the Worker

A CoS withdrawal affects a candidate differently depending on where they are in the visa process:

• Visa Not Yet Applied For: The CoS reference number becomes instantly invalid. The candidate cannot proceed until you issue a new one.
• Visa Application In Progress: UKVI must be notified. The application will be refused unless the candidate formally withdraws it first.
• Worker Already in the UK: Proceed with extreme caution. If the worker is relying on Section 3C leave (staying legally while awaiting a visa decision), withdrawing the CoS can immediately end their lawful stay in the UK. Seek legal advice before acting.

HR Best Practice: Communicate changes immediately. Candidates take major financial and personal risks to move to the UK. Being transparent and documenting everything protects your reputation as an international employer.

Impact on Your Sponsor Licence

• A single withdrawal with a documented business reason is unlikely to trigger a compliance review.
• Repeated withdrawals, especially without clear documentation, can raise red flags during a Home Office audit. UKVI looks for patterns that suggest speculative CoS assignment.
• Always document the reason for every withdrawal in your Appendix D records. "Role made redundant" or "worker withdrew acceptance" is defensible. An undocumented withdrawal is not.
• If the withdrawal involves a worker who has already submitted a visa application, the compliance stakes are higher, seek advice from a CoS management specialist before proceeding.

Best Practices to Avoid Unnecessary CoS Withdrawals

• Double-Check Core Details: Verify the SOC code, salary threshold, and job description against UKVI rules before hitting submit. Review against the CoS Document checklist.
• Match Passports Exactly: Cross-check the candidate’s name, date of birth, and nationality. Typos in these fields often cannot be fixed with a sponsor note and require a full restart.
• Get Written Acceptance: Never assign a Defined CoS based on a verbal agreement. Secure written confirmation from the candidate first to ensure they are committed.
• Create Internal Sign-Offs: Require dual approval from HR and the hiring manager before generating a CoS to catch last-minute role or salary changes.
• Track Expiry Dates: Set automated alerts for the 3-month Defined CoS validity window. Letting a CoS lapse means paying new fees and delaying your hire.
• Consult Experts for Complex Cases: Seek specialist advice immediately if a candidate has already submitted their visa, or if the cancellation involves redundancy, misconduct, or failed background checks.

Leverage Global Mobility Tech: Avoid manual mistakes entirely by using a managed service like Jobbatical. We run pre-submission compliance checks on every CoS to catch errors before they reach the SMS portal. Book a demo to see how it works.

Summary

• CoS withdrawal is easy when the worker has not yet applied for a visa; but gets complicated, and consequential, once a visa application is live. 
• It is important to understand the difference between withdrawal and termination reporting as it has compliance breach and serious disruption risk to your worker's immigration status.
• If you are unsure whether withdrawal is the right step, or if you are dealing with a live visa application, talk to Jobbatical's UK immigration team before actioning anything in the SMS.
