Sponsor licence reporting usually becomes important because something ordinary has happened inside the business.
An employee resigns.
Their salary changes.
They are promoted.
They stop attending work.
They move permanently to another office.
The company changes address.
A director responsible for sponsorship leaves.
The business is acquired.
None of those events begins as an immigration application. Some of them nevertheless create a Home Office reporting obligation. For licensed Worker and Temporary Worker sponsors, the broad timetable is:
Changes affecting a sponsored worker usually need to be reported within 10 working days.
Specified changes affecting the sponsoring organisation usually need to be reported within 20 working days.
There are exceptions and some events have their own rules. The real compliance challenge is therefore not memorising the numbers 10 and 20. It is making sure the person responsible for the sponsor licence finds out that something has changed while there is still time to report it.
Why sponsor reporting duties matter
The Home Office sponsorship system relies partly on employers providing information after a worker has been sponsored.
UKVI does not sit inside the business.
It will not automatically know that an employee has resigned, moved office or received a significant change in duties.
The reporting system is designed to keep the sponsorship record aligned with what is happening in practice.
That means reporting duties are not simply an administrative addition to the licence.
They are part of the bargain the organisation accepts when it becomes a sponsor.
Failure to meet sponsor duties can result in compliance action.
Depending on the seriousness and circumstances, that can include reduction of the organisation’s Certificate of Sponsorship allocation, downgrade to a B-rating, suspension or revocation of the sponsor licence.
The sensible objective is therefore not merely to report changes after somebody remembers.
It is to build reporting triggers into ordinary business processes.
The basic rule: 10 working days for worker changes
Current Home Office sponsor guidance requires specified changes affecting sponsored workers to be reported within 10 working days of the relevant event occurring, unless a different period applies.
This can include changes relating to:
- delayed starts
- unauthorised absence
- certain periods of unpaid or reduced-pay absence
- salary reductions
- certain changes to job role, title or duties
- changes to normal work location
- the end of sponsorship
- additional route-specific matters
Most worker reports are made through the Report migrant activity function in the Sponsorship Management System.
That sounds simple.
The difficult part is determining whether the event falls into a category that can simply be reported, whether no report is needed, or whether the proposed change is significant enough to require a new immigration application.
A report does not make an otherwise impermissible employment change lawful.
The basic rule: 20 working days for organisational changes
Changes to the sponsoring organisation usually operate on a different timetable.
Specified organisational changes must generally be reported within 20 working days after the sponsor became aware of the change, unless another rule applies.
These can include changes to:
- organisation name
- address or head office
- contact details
- branches or sites
- organisational structure
- legally required registrations or accreditations
- size classification or charitable status
- business activities
- insolvency position
- Key Personnel
- mergers, takeovers and similar transactions
Some of these changes are straightforward updates.
Others can affect whether the existing sponsor licence can continue at all.
A change in office address is not the same type of sponsorship event as a change in direct ownership.
Both may need action, but the consequences are very different.
“The reporting deadline is rarely the difficult part. The difficult part is recognising that something ordinary inside the business is also a sponsorship event. Payroll sees a salary change. A manager sees a promotion. The company secretary sees a restructure. The Level 1 User needs the right information from all three.”
Abdul Jabbar, Principal Immigration Adviser
What if a sponsored worker does not start on time?
A Certificate of Sponsorship contains an intended employment start date.
Real recruitment does not always run precisely to that date.
A worker may have notice to serve.
Travel can be delayed.
A visa decision may arrive later than expected.
A family issue may interfere with relocation.
The sponsor guidance allows some flexibility around delayed starts.
The key issue is whether the worker starts within the permitted period.
Where a sponsored worker does not begin the sponsored role within 28 days of the relevant date specified by the sponsor guidance, the sponsor needs to consider its reporting obligations and whether it will continue sponsoring them.
This should not be left unresolved simply because the employer still intends to employ the person eventually.
A delayed start needs to be understood and recorded.
Where action is required through the SMS, the reason for the delay should be explained accurately.
Unauthorised absence
A sponsored worker who is absent from work without permission for more than 10 consecutive working days must be reported.
Importantly, this reporting duty can arise even where the employer intends to continue sponsoring them.
The report must normally be made no later than 10 working days after the tenth day of unauthorised absence.
The Home Office expects relevant information about the absence, which can include:
- when the unauthorised absence began
- whether and when the worker returned
- attempts to contact them
- any salary deductions
- whether sponsorship will continue
This is a good example of why line managers need some awareness of the sponsor process.
The Level 1 User is unlikely to be the first person to notice that an employee has stopped attending work.
The manager is.
If that information sits within the department for three weeks before reaching HR, the sponsor may already have a reporting problem.
Unpaid or reduced-pay absence
There are separate rules concerning sponsored workers who are absent without pay or on reduced pay.
As a general position, a sponsored worker should not remain away from work without pay, or on reduced pay, for more than four weeks in total in a calendar year unless one of the permitted exceptions in the sponsor guidance applies.
Where the relevant circumstances arise, the sponsor may need to report the absence.
Specified exceptions can apply to particular forms of authorised absence.
This is an area where employers should avoid treating every period of reduced pay in the same way.
Statutory family leave, sickness-related arrangements and other permitted circumstances may operate differently from an employee simply taking a lengthy unpaid career break.
The immigration position should be checked against the reason for the absence.
Salary reductions
A reduction in a sponsored worker’s salary or pay from the level stated on their Certificate of Sponsorship is generally reportable.
This deserves particular care.
A salary change can arise in many ways:
- reduced working hours
- a business-wide pay reduction
- removal of a regular allowance
- contractual variation
- change in responsibilities
- return from a temporary arrangement
- reduced pay during an absence
The employer needs to do more than make the SMS report.
It must also consider whether the worker continues to meet the salary requirements of their sponsored route.
If a Skilled Worker is no longer being paid enough to satisfy the Immigration Rules, reporting the reduced figure does not solve the underlying problem.
The immigration assessment should therefore take place before the salary change is implemented wherever possible.
Do salary increases need to be reported?
Ordinary salary increases generally do not need to be reported merely because the worker is now earning more than the amount on their CoS.
There are route-specific exceptions.
For example, particular reporting requirements can arise in relation to a pre-registration nurse or midwife completing the relevant registration process.
For most employers, the main reporting risk is therefore salary reduction rather than a routine annual increase.
The business should still retain accurate payroll and employment records.
A salary increase may not require an SMS report, but the sponsor should be able to explain what the worker is actually being paid if UKVI later compares sponsorship information with HMRC records.
Promotions and changes to job duties
Sponsored workers can be promoted.
Their job titles can change.
Their responsibilities can develop.
But the immigration consequence depends on what has actually changed.
A significant change in role, title or core duties can potentially be reported where the new position remains within the same occupation code and the relevant conditions in the sponsor guidance are satisfied.
A more fundamental change may require a new Certificate of Sponsorship and a new immigration application before the worker starts the new role.
That distinction matters.
Suppose an employee is promoted from Senior Analyst to Team Lead.
If the underlying occupation remains the same and the duties continue to fit the same occupation code, reporting may be sufficient.
Suppose instead that an employee moves from an engineering role into a substantially different commercial management position.
That may be a different sponsorship event entirely.
The answer is found in the duties, not in the word “promotion”.
Report first or implement first?
Where a proposed employment change may affect sponsorship, the safest internal sequence is usually:
identify the proposed change,
check the immigration implications,
decide whether it is permissible,
establish whether a report or fresh application is required,
then implement it in the correct order.
This is preferable to changing the employee’s role on Monday and asking the immigration question three months later.
Businesses naturally want employment decisions to move quickly.
Sponsor compliance does not need to obstruct that.
It simply needs to be part of the approval process for sponsored workers.
Changes to normal work location
A sponsor must report a change to a sponsored worker’s normal work location where required.
This can include a worker moving to:
- another branch
- a different regular client site
- another location not previously recorded
- permanent or substantially full-time home working
The key idea is the normal working arrangement.
Day-to-day movement does not ordinarily need reporting.
A worker attending another branch for a meeting is not the same as permanently transferring to it.
A consultant spending one afternoon at a client site is not necessarily changing their normal work location.
The sponsor guidance focuses on material changes to the regular working pattern.
What about hybrid working?
The Home Office recognises hybrid working.
A sponsored worker can work part of the week remotely and part from the sponsor’s office or another regular workplace.
Moving into a hybrid working arrangement does not, by itself, need to be reported simply because the worker now works from home on some days.
The sponsor must still:
- report changes to the worker’s main office location where applicable
- report new regular client sites where required
- keep suitable records of working patterns
The position is different where the worker becomes a contractual home worker with little or no requirement to attend the employer’s premises or a client site.
Permanent or substantially full-time remote working must be reported.
The Home Office also reserves the right to ask why a worker needs sponsorship to come to the UK if the role can apparently be performed entirely remotely from another country.
When sponsorship ends
A sponsor must report when it stops sponsoring a worker.
This can happen for many reasons.
The employee may:
- resign
- be dismissed
- be made redundant
- decide not to take up the job
- have their offer withdrawn
- finish employment earlier than the CoS end date
- obtain settlement
- move onto an immigration route that no longer requires sponsorship
There can also be circumstances in which sponsorship must end because a required professional registration has been withdrawn or because an employment arrangement no longer complies with the sponsorship rules.
The report should reflect the actual reason.
Where the sponsor reports that it is no longer sponsoring the worker, the Home Office requires additional contact information, including the last recorded residential address, telephone number and personal email address held for the worker.
This information can subsequently be relevant to action on the worker’s immigration permission.
What happens to the worker after sponsorship ends?
The employer reports the sponsorship event.
The Home Office decides what happens to the individual’s immigration permission.
Those are separate functions.
An employer should not tell the worker that their permission has automatically ended on the date of resignation unless that is actually the legal position.
Nor should it promise that they will have a guaranteed period in which to find another sponsor.
UKVI may subsequently take cancellation action.
The worker’s immigration position needs to be considered separately.
The sponsor’s responsibility is to make the required report accurately and on time.
What changes to the business need reporting?
The sponsor guidance requires significant organisational changes to be reported.
Some of the most common are deceptively ordinary.
Change of address
If the business changes its main or head office address, the sponsor licence needs to be updated.
Where Key Personnel work at the same location, their address information may also need to be updated separately.
The SMS may require more than one action.
A sponsor should not assume that changing the company address in one place automatically updates every connected record.
Change of business name
A change to the organisation’s name or the name of relevant branches should be reported.
Supporting information may be required.
New branches or sites
Changes to the organisational structure, including additional branches or sites, can require reporting.
This can be particularly important where sponsored workers will be based at those locations.
Regulatory registration
If the organisation requires a registration, licence or accreditation to trade lawfully or for sponsorship purposes, a change in that status needs to be reported.
Losing a legally required regulatory authorisation can have consequences beyond a simple administrative update.
Change in sponsor size
A Worker sponsor should report where its size classification changes, for example from small to large or large to small.
The same applies where charitable status is gained or lost.
This matters because sponsor size can affect Home Office charges, including the Immigration Skills Charge.
Key Personnel changes
The sponsor licence needs current Key Personnel.
Changes to the Authorising Officer, Key Contact and relevant SMS users need to be managed through the correct sponsor process.
This has become increasingly important with the latest SMS changes.
New Level 2 Users can no longer be appointed from 9 September 2026, and Level 1 access is subject to the updated Home Office security and multi-factor authentication arrangements.
A departing employee should not remain indefinitely as the business’s sponsorship contact.
Likewise, an organisation should not discover after somebody leaves that they were the only person capable of accessing the SMS.
Key Personnel should form part of the leaver process for anyone involved in sponsorship.
Insolvency and stopping trade
If the organisation stops trading or enters an insolvency process, sponsorship needs immediate attention.
The Home Office must be informed.
The consequences depend on the particular event and what happens to the business and its sponsored workers.
This is not an area where a company should simply wait for insolvency practitioners to update Companies House.
The sponsor licence has its own reporting requirements.
If sponsored workers move to another entity, the merger, takeover or TUPE rules may also become relevant.
Mergers, acquisitions and changes of ownership
Corporate transactions have separate and potentially serious sponsor implications.
A sponsor licence is not transferable.
Where direct ownership changes, a new licence may be required even if the employing company continues to exist.
Where sponsored workers transfer to another employer under TUPE or similar protection, both outgoing and incoming sponsors may have obligations.
These changes generally operate within the 20-working-day reporting framework, but the analysis should happen before the transaction completes.
Reporting is not the only question.
The transaction may change which legal entity is entitled to sponsor the workers at all.
Substantial changes to the nature of the business
The Home Office also expects sponsors to report where the nature of the business changes substantially.
Not every new product line creates a sponsor report.
Businesses evolve.
The issue is material change.
If an organisation originally licensed as a technology consultancy transforms into a materially different type of operation, that may affect the Home Office’s understanding of the sponsor, its roles and its suitability to continue sponsoring workers.
Where there is doubt, the business should consider the significance of the change rather than assuming it is irrelevant because the company number remains the same.
The reporting clock depends on information moving internally
This is where sponsor reporting most often becomes operationally difficult.
Take a 100-person company.
Payroll knows salary.
HR knows contracts.
Line managers know duties and absences.
Facilities knows office moves.
The company secretary knows ownership changes.
The Level 1 User knows the SMS.
No one person naturally sees every relevant event.
So sponsor reporting needs an escalation structure.
Payroll needs to know that reducing a sponsored worker’s salary requires review.
Managers need to know that a material change of duties should be escalated.
HR needs to identify sponsored workers when approving contractual changes.
Senior management needs to involve the sponsor function in corporate transactions.
The Level 1 User does not need to control every business decision.
They need to receive the information in time.
“A reporting system should sit inside the business, not beside it. The immigration adviser or Level 1 User cannot report a change they were never told about. The practical question is always: who learns about this event first, and how does it reach the person responsible for sponsorship?”
Abdul Jabbar, Principal Immigration Adviser
Should every change be reported just to be safe?
No.
Over-reporting is not necessarily good compliance.
The purpose is to make the reports the sponsor guidance requires.
Reporting every minor event can create unnecessary records and make the licence harder to manage.
A sponsored worker changing desk within the same office is not ordinarily a Home Office event.
Occasional home working is not the same as a permanent change in normal work location.
A routine salary increase usually does not need to be reported.
A minor evolution in duties does not automatically amount to a new sponsored role.
The correct approach is neither under-reporting nor reporting everything.
It is understanding the threshold.
What if you are unsure whether a change is reportable?
Start by identifying the facts precisely.
“Job changed” is too vague.
What duties changed?
Did the occupation code change?
“Worker is remote” is too vague.
Do they work from home twice a week, or have they permanently stopped attending any workplace?
“Salary changed” is too vague.
Did it increase, decrease or change because hours changed?
Once the facts are clear, check the current sponsor guidance and relevant route-specific rules.
That is often enough to resolve the question.
Where the change could affect the worker’s immigration eligibility, the answer should be established before the employment change is implemented.
What if a reporting deadline has already been missed?
Do not invent a report date.
Do not alter records to suggest the business acted earlier.
First establish:
what happened,
when it happened,
when the business became aware,
whether the event remains reportable,
whether the underlying employment arrangement is lawful,
and whether the same problem affects other workers.
A late report may be appropriate, with an accurate explanation.
More significant historic failures may require a broader compliance review.
The correct response depends on the nature of the missed event.
The important point is that discovering a late report is a reason to investigate, not a reason to create a false history.
Keep evidence of reporting
The organisation should have a reliable way of showing what it reported and when.
SMS activity itself provides part of that record.
For internal compliance purposes, it can also be useful to retain the information supporting the decision.
If a worker’s salary was changed, keep the relevant employment and payroll record.
If a work location changed, retain the evidence explaining the arrangement.
If a promotion was assessed as remaining within the same occupation code, retain an appropriate record of the assessment.
This makes future audits and compliance visits easier.
The objective is not to create paperwork for its own sake.
It is to be able to reconstruct why a sponsorship decision was made.
A simple reporting matrix can help
For many employers, a short internal matrix is enough.
For example:
Employee resigns
HR informs Level 1 User immediately.
Salary or hours proposed to change
Payroll or HR seeks sponsorship review before implementation.
Duties or promotion proposed
Manager informs HR before the change.
Normal work location changes
HR or Facilities escalates before permanent move.
Unauthorised absence
Manager escalates once internal trigger is reached, before the Home Office deadline.
Company address changes
Company Secretary or Operations informs Authorising Officer.
Corporate transaction
Sponsor licence implications considered before completion.
That does not replace the sponsor guidance.
It gives the organisation a mechanism for spotting events to which the guidance may apply.
Frequently asked questions
How long do sponsors have to report worker changes?
Unless a different period applies, specified changes affecting a sponsored worker must generally be reported within 10 working days of the relevant event.
How long do sponsors have to report business changes?
Specified changes affecting the sponsor organisation must generally be reported within 20 working days, subject to the detailed rules applying to the event.
Do I have to report a sponsored worker’s salary increase?
Ordinary salary increases generally do not need to be reported simply because pay has increased, although route-specific exceptions can apply.
Salary reductions require much greater care.
Do I have to report a change in working hours?
Potentially.
A change in hours can affect salary and the conditions under which the worker qualified for sponsorship.
The immigration effect should be assessed before implementing a material change.
Do I need to report hybrid working?
Not simply because a sponsored worker adopts an ordinary hybrid pattern.
Changes to the main office, new regular client locations or permanent or substantially full-time home working can require reporting.
Do I need to report when a sponsored employee resigns?
Yes.
The sponsor must report that it has stopped sponsoring the worker.
Do I need to report a promotion?
Potentially.
A promotion or significant change in job title or duties may be reportable where the worker remains within the same occupation code and the relevant conditions are met.
A more substantial change can require a new immigration application.
Do I need to report an office move?
Yes, a relevant change to the sponsor’s main or head office details needs to be reported through the sponsorship management process.
Do I need to report if the company becomes larger?
Worker sponsors must report changes to their size classification where relevant because this can affect sponsorship fees and the Immigration Skills Charge.
What happens if a sponsor forgets to report a change?
Failure to meet reporting duties can lead to Home Office compliance action.
The appropriate response depends on what was missed, how late the report is, whether the underlying change was permissible and whether the failure indicates a wider compliance problem.
Good reporting starts before the deadline
The most effective sponsor reporting systems do not begin when somebody logs into the SMS.
They begin where the business decision happens.
When payroll receives a salary instruction.
When the manager agrees a promotion.
When HR processes a resignation.
When the board approves an office move.
When the company begins discussing a sale.
Those are the moments when sponsorship needs to enter the conversation.
Once the right information reaches the Level 1 User, making the report itself is usually the straightforward part.
The real compliance work is ensuring that sponsorship is connected to the normal operation of the organisation.
That is why the 10-working-day and 20-working-day rules should not simply sit in an immigration manual.
They should sit behind the processes that generate reportable events.
If the business gets that right, reporting becomes routine.
If it does not, the first person to connect the event with the sponsor licence may eventually be a Home Office compliance officer.
Unsure whether a change needs to be reported?
If your organisation holds a sponsor licence and a sponsored worker’s role, salary, work location or circumstances have changed, or the business itself has undergone a material change, you can request a Free Case Assessment.
Tell us what changed, when it happened and which sponsored workers are affected.
We can then consider the reporting position and whether Knightsbridge Immigration can assist.
