If your organisation holds a UK sponsor licence, keeping the Home Office up to date with any changes to your business or sponsored workers is not optional – it is a legal requirement. Failing to report changes on time, or using the wrong reporting method, can put your licence at serious risk. Most changes are reported through the Sponsor Management System (SMS), but in a small number of situations, a separate sponsor change of circumstances form must be used instead. This guide explains what you need to report, when you need to report it, how to do it correctly, and what happens if things go wrong.
What the sponsor change of circumstances duty actually means
Every organisation that holds a sponsor licence has an ongoing legal duty to inform the Home Office of certain changes – both to the organisation itself and to the circumstances of any workers it sponsors. This duty sits at the heart of the UK sponsorship system, which places a significant level of trust and responsibility on employers. The Home Office monitors compliance continuously and will take enforcement action where sponsors fail to meet their reporting obligations.
In most cases, changes are reported through the Sponsor Management System using either the “Request changes to licence details” or “Report migrant activity” function, depending on the nature of the change. The sponsor change of circumstances form is only used in a limited number of specific situations where SMS access is unavailable – it is not a general-purpose reporting tool and should not be used as a substitute for the SMS.
What organisational changes must be reported to the Home Office
Significant changes to your organisation must generally be reported within 20 working days of the change occurring or of you becoming aware of it. The following are the main types of organisational changes that trigger a reporting duty:
- Any change to the Authorising Officer (AO) or Key Contact (KC), including their personal details
- Any amendment to the sponsor organisation’s name, address, contact details, or head office information
- Changes to the structure of the organisation, such as new branches, sites, or linked entities
- Any change to a registration, accreditation, or approval that the sponsor must hold in order to operate lawfully or to maintain its licence
- The organisation stopping trading or entering an insolvency procedure
- A merger, takeover, demerger, or outsourcing or insourcing arrangement
- A relevant criminal conviction affecting the owner, a director, any key personnel, or anyone involved in day-to-day management
- Any change to the size or charitable status of the organisation where this affects eligibility for fee reductions or route-specific concessions
- Any other significant change to the licence, including adding or removing a representative or surrendering the licence
What worker-related changes must be reported to the Home Office
Changes relating to individual sponsored workers must generally be reported within 10 working days of the relevant event occurring. The following circumstances trigger a reporting duty:
- A sponsored worker does not start their role within 28 days of the start date on their Certificate of Sponsorship, or the date stated on their visa or grant notification, whichever is later
- A sponsored worker is absent from work without permission for more than 10 consecutive working days
- A sponsored worker is absent without pay or on reduced pay for more than four weeks in total in any calendar year, unless a valid exception applies
- A sponsored worker’s salary is reduced from the level stated on their Certificate of Sponsorship
- There are significant changes to the worker’s employment, such as a change of job role or core duties, or a promotion within the same occupation code
- A sponsored worker’s normal work location changes, including to a different site, branch, or client location not previously declared to the Home Office
- A sponsored worker moves to fully remote working or changes their regular working pattern
- A sponsored worker leaves their employment or is no longer being sponsored for any reason
It is worth noting that since changes to the sponsor rules in 2022, sponsors no longer need to report a delayed start where the delay is under 28 days. However, where the delay exceeds 28 days, reporting becomes mandatory unless a recognised exception applies.
When the sponsor change of circumstances form is used instead of the SMS
The sponsor change of circumstances form is a Home Office document that exists specifically for situations where a sponsor licence holder does not have access to the SMS. It is not intended for routine reporting and should only be used in the following circumstances:
- Adding a Level 1 user where no one in the organisation currently has SMS access
- Replacing an Authorising Officer where that individual is also the sole Level 1 user, meaning no one else can make the change through the SMS
- Requesting surrender of the licence where no one in the organisation has SMS access
- Requesting that the licence be made dormant where no one currently has SMS access
The completed form must be emailed to sponsors@homeoffice.gov.uk. Processing under the standard service can take up to 18 weeks, so it is important to act promptly as soon as one of these situations arises. Using the form in any other situation, or using it instead of the SMS when SMS access is available, is likely to result in a missed reporting deadline and a compliance breach.
Who can report changes on behalf of a sponsor
In most cases, changes to the licence or the organisation must be reported by a Level 1 user through the SMS. Level 2 users can report changes in migrant activity, but only in relation to Certificates of Sponsorship that they have personally created and assigned, or that have been transferred to them.
A sponsor must have at least one Level 1 user in place at all times, unless it is in the process of surrendering its licence. If a Level 1 user leaves and no replacement has been added, the sponsor will lose SMS access and will need to use the sponsor change of circumstances form to either add a new Level 1 user or take one of the other actions listed above.
This situation highlights why it is so important to maintain continuity of key personnel on the licence and to ensure that replacements are added promptly whenever someone in a named role leaves the organisation.
How long the Home Office takes to process change requests
Under the standard service, change of circumstances requests can take up to 18 weeks to be processed. This is a significant waiting period, particularly where the change relates to key personnel or Certificate of Sponsorship allocations that are needed for active recruitment.
For eligible sponsors, a priority service is available that aims to process certain types of change within five working days. The fee for using the priority service is Β£350 per request. This fee is non-refundable if the request is rejected, and the service does not guarantee approval – it only accelerates consideration. The priority service is available to A-rated Worker and Temporary Worker sponsors and can be used for changes such as updating key personnel, requesting additional undefined CoS allocation, and amending organisation details. It cannot be used for defined CoS requests, Student route cases, or certain Global Business Mobility sub-routes.
If your case is approaching the 18-week standard processing deadline without a decision, you can contact the Home Office by email, noting the submission date in the subject line.
How much it costs to report a change of circumstances
Reporting a change of circumstances through the standard service is free of charge. The priority service costs Β£350 per request, and each separate SMS action requires its own fee if priority handling is requested. The standard service fee is nil regardless of how many changes are being reported, though each change must be submitted as a separate action in the SMS where more than one is required.
What the priority change of circumstances service covers
The priority service allows A-rated Worker and Temporary Worker sponsors to request faster consideration of certain post-licence change submissions. Eligible request types include adding or changing a Level 1 user, replacing or updating the Authorising Officer or Key Contact, requesting additional or annual undefined Certificate of Sponsorship allocation, appointing a representative, and updating organisation details such as a business address.
To use the service, the change must first be submitted through the SMS. Once that is done, an email must be sent to postlicencepriorityservice@homeoffice.gov.uk with the subject line: “Priority service request: [organisation name] ([sponsor licence number]): [request type]”. The Worker and Temporary Worker priority request form must be attached, along with all supporting documents. For certain changes β such as replacing an Authorising Officer or appointing a representative β a signed submission sheet generated from the SMS must also be included.
The mailbox operates Monday to Friday from 7am to 5pm UK time. A minimum of 120 requests are accepted each working day, but demand is high and the daily allocation often fills early. Submitting shortly after 7am gives the best chance of acceptance. If accepted, a payment link will be sent and must be paid within 72 hours – weekends count toward this deadline. If no confirmation is received, you should assume the request was not accepted and plan accordingly.
What happens if a sponsor fails to report changes on time
The consequences of missing a reporting deadline or failing to report at all can be serious. The Home Office treats non-compliance with reporting duties as a significant breach of sponsor obligations, and enforcement action is likely where failures are identified.
At the lower end, a missed or late report may result in the licence being downgraded from an A-rating to a B-rating. A B-rated sponsor cannot assign new Certificates of Sponsorship and must follow and fund a Home Office action plan to reinstate their A-rating within three months. This carries both financial and operational costs.
More serious or repeated breaches can result in the licence being suspended while a compliance investigation is carried out. In the most severe cases – where non-compliance is systemic or particularly serious – the licence can be revoked entirely. Revocation means the loss of the entire sponsored workforce, as existing workers would need to find an alternative sponsor or face having their leave curtailed. A 12-month cooling-off period applies before a new licence can be applied for.
It is also important to understand that reporting a change can itself trigger a compliance review. For example, reporting a worker’s unauthorised absence may prompt the Home Office to examine the sponsor’s broader HR systems and practices. This is not a reason to avoid reporting – failing to report carries far greater risks – but it does underline the importance of having robust internal compliance processes in place before any issue arises.
How to make sure your organisation stays on top of its reporting duties
The practical challenge for most sponsors is not understanding the rules in the abstract – it is recognising in the day-to-day running of the business when a reportable event has occurred and making sure the right person knows about it in time to act. Common failure points include HR not being informed of a change, staff being too busy with other demands, or uncertainty about which reporting route applies.
The Home Office will not accept operational pressure or internal miscommunication as justification for missed deadlines. Sponsors should put in place clear internal notification and escalation procedures so that key information does not fall through the gaps. This means ensuring that Level 1 users are trained, that HR and line managers know which events need to be escalated, and that there is always at least one active Level 1 user with SMS access in place at all times.
Where more than one change needs to be reported, remember that each must be submitted as a separate action in the SMS, even if they relate to the same underlying event. For example, a change of address may also require a separate update to the working address details for key personnel.
