Sponsor Licence FAQs for UK Employers
Holding a Sponsor Licence involves more than submitting the original application — employers must understand how sponsorship works in practice, including Certificates of Sponsorship, record keeping, reporting, sponsored roles, SMS management and Home Office compliance. These FAQs give concise answers to common employer questions and link to the detailed page that owns each topic. Where the answer depends on the particular organisation, worker or arrangement, we say so rather than turn a fact-sensitive rule into a blanket answer.

Applying for a Sponsor Licence
What does a Sponsor Licence allow an employer to do? +
It allows a Home-Office-approved organisation to sponsor eligible workers on the routes it's licensed for. Holding the licence doesn't mean every proposed job or worker can automatically be sponsored — the relevant route and sponsorship requirements still need to be met. Sponsor Licence overview →
Does every UK business qualify for a Sponsor Licence? +
No. The Home Office assesses whether the organisation is eligible and suitable — including whether it's genuine and operating lawfully, can offer appropriate sponsored work and has systems capable of meeting sponsor duties. Eligibility →
Does a business need a dedicated HR department? +
No. The guidance doesn't require a separate HR department — it requires appropriate HR or other systems and processes capable of supporting sponsor duties. Eligibility · sponsor duties.
Can a small or newly established business obtain a Sponsor Licence? +
There's no rule that only large or long-established organisations can be licensed. The Home Office assesses whether the organisation genuinely operates and can meet the applicable licence, role and compliance requirements. Eligibility →
Can a virtual business obtain a Sponsor Licence? +
A virtual business isn't automatically excluded, but the Home Office may scrutinise where it operates and where sponsored workers work — and a pre-licence compliance check is highly likely where there's little or no physical office space. Eligibility · compliance checks.
Documents and application
What documents are required for a Sponsor Licence application? +
The documents depend on the organisation and sponsorship route. Appendix A contains the supporting-document framework and identifies where particular evidence is required. Supporting documents →
Is there one standard list of four Sponsor Licence documents? +
Not as a universal rule. Appendix A contains different requirements and exceptions depending on the organisation and route — the correct evidence should be identified from the current source applying to that sponsor. Supporting documents →
Can the Home Office ask for additional information after the application? +
Yes. The guidance allows the Home Office to request and verify information, and it may conduct a compliance check where necessary before deciding the application. Application process · compliance checks.
Can the Home Office visit the business before granting a licence? +
Yes. Pre-licence compliance checks form part of the Home Office assessment and can test whether the organisation is genuine and capable of meeting sponsor duties. Compliance checks →
Key Personnel and SMS
Who manages the Sponsor Licence? +
The framework requires Key Personnel, including an Authorising Officer and relevant SMS users. The Authorising Officer provides senior oversight, while authorised Level 1 and Level 2 Users carry out permitted SMS functions. Key Personnel →
Does the Authorising Officer have to use the SMS personally? +
Not necessarily. The Authorising Officer has senior responsibility for sponsorship activity, while permitted SMS functions can be undertaken by appropriately appointed Level 1 and Level 2 Users. Key Personnel →
Can an immigration adviser or representative use the SMS? +
The guidance permits external representatives to hold specified SMS roles in certain circumstances after grant. The sponsor nevertheless remains responsible for activity carried out through its licence. Key Personnel · SMS.
What is the Sponsorship Management System? +
The SMS is the Home Office online system licensed sponsors use to manage sponsorship functions such as CoS activity, reporting, allocations and specified licence/user changes. SMS →
Certificates of Sponsorship
What is a Certificate of Sponsorship? +
A CoS is an electronic sponsorship record a licensed sponsor assigns to a worker in support of an immigration application. It's not itself a visa or immigration permission. CoS overview · applicant-side.
What is the difference between Defined and Undefined CoS? +
For Skilled Worker, a Defined CoS is used where the worker applies for entry clearance from outside the UK; an Undefined CoS is used where the Skilled Worker applies for permission to stay from inside the UK. Other sponsored routes use Undefined CoS under the general framework. Defined vs Undefined →
Can an employer use an Undefined CoS because it already has one available? +
Not if a Defined CoS is required. Using an Undefined CoS where a Defined CoS is required can result in serious Sponsor Licence action. Defined vs Undefined →
Does assigning a CoS guarantee that the worker's visa will be granted? +
No. The immigration application is decided separately by the Home Office. CoS overview · Skilled Worker route.
How long can an assigned CoS be used? +
The guidance sets a time limit within which an assigned CoS must be used in a valid application — currently 3 months from assignment (as at August 2026 — confirm against the latest guidance). Assigning a CoS →
Sponsored jobs and occupation codes
Does appearing on an eligible occupation list mean the job can automatically be sponsored? +
No. Role eligibility is broader than occupation-code eligibility — the role must genuinely exist, correspond with the actual duties and arrangements, meet the route requirements and be appropriate to the sponsor's business. Genuine role · occupation codes.
Can an employer change the job description to fit an eligible occupation code? +
The occupation code should reflect the actual sponsored job. The Home Office can scrutinise cases where an inappropriate code or exaggerated job description appears to have been used. Genuine role · occupation codes.
Must every sponsored job be advertised? +
The general guidance doesn't impose a blanket advertising requirement. Where recruitment was undertaken, Appendix D requires specified evidence to be retained — and if the role wasn't advertised, the sponsor should be able to explain how the worker was identified. Genuine role · record keeping.
Can a sponsored worker work at a client's premises? +
Potentially, but the arrangement must comply with the third-party working rules. The sponsor must retain the required responsibility for the worker's role — sponsorship can't be used simply to supply routine labour to another organisation. Genuine role →
Immigration Skills Charge and sponsorship costs
Who pays the Immigration Skills Charge? +
The ISC is an employer sponsorship charge where it applies. The sponsor must not pass it on to, or recover it from, the sponsored worker. Immigration Skills Charge →
How much is the Immigration Skills Charge? +
The amount depends on the sponsor's size/status, the sponsored period and the current rates. Use the current ISC estimator for the verified rate rather than a remembered figure. ISC estimator →
Is every Skilled Worker subject to the ISC? +
No. The current guidance contains exemptions, including specified worker, occupation and circumstance-based exemptions. Immigration Skills Charge →
Is the ISC refunded if the Sponsor Licence is revoked? +
No. The current guidance expressly lists Sponsor Licence revocation among the circumstances where the ISC is not refunded. Immigration Skills Charge →
Ongoing Sponsor Licence duties
Do sponsor duties continue after the licence is granted? +
Yes. Sponsor duties begin when the licence is granted and continue while the licence remains active. Sponsor duties →
What changes must sponsors report? +
The guidance requires specified changes affecting sponsored workers and the sponsor organisation to be reported. The particular event and deadline should be checked against the reporting guidance. Reporting duties →
What records must sponsors keep? +
Appendix D requires prescribed records relating to sponsored workers, recruitment, employment, pay and other sponsorship matters, together with specified Sponsor Licence application evidence. Record keeping →
Can sponsor records be stored electronically? +
Yes. The guidance allows records to be retained in permitted electronic or paper form, provided required evidence remains available for Home Office inspection. Record keeping →
Reporting worker changes
Does a sponsor need to report when a worker resigns or is dismissed? +
Where sponsorship ends earlier than the date recorded for sponsorship, the sponsor must make the applicable report. Reporting duties →
Do salary changes have to be reported? +
Specified salary changes fall within the reporting framework. Employers must also separately check that the changed salary remains compatible with the worker's immigration route. Reporting · salary requirements.
Do changes in work location have to be reported? +
Specified changes to a sponsored worker's work location are reportable. Reporting duties →
What if the worker does not start employment? +
Establish why the worker hasn't started and apply the current start-date/reporting provisions. A delayed start can have both CoS and reporting consequences. Assigning a CoS · reporting.
Business changes and Sponsor Licence ownership
Can a Sponsor Licence be transferred when a company is sold? +
No. A Sponsor Licence is not transferable. A change in direct ownership can require different Sponsor Licence action, including a new licence application by the receiving organisation. Changes, mergers & takeovers →
Does every shareholder change mean a new Sponsor Licence is required? +
Not necessarily. The guidance distinguishes changes in direct ownership from certain changes further up the corporate ownership structure. Changes, mergers & takeovers →
What happens to sponsored workers under TUPE? +
Where the conditions for TUPE or similar protection are met, workers can transfer sponsorship responsibility without a new application or new CoS merely because of the transfer. The receiving organisation must hold or obtain the appropriate licence and meet the applicable requirements. Changes, mergers & takeovers →
Home Office compliance checks
Can the Home Office visit without notice? +
Yes. Compliance visits and interviews can be announced or unannounced. Compliance checks →
Can UKVI interview sponsored workers? +
Yes. Compliance officers can interview sponsored workers and other relevant people involved in sponsored recruitment and employment. Compliance checks →
Will the compliance officer tell the employer whether it passed? +
No. The compliance officer doesn't provide an on-the-day assessment — UKVI later communicates its decision in writing. Compliance checks →
B-rating and action plans
What does a B-rated Sponsor Licence mean? +
A B-rating means the licence remains in place but the sponsor is subject to restrictions and normally must follow a sponsorship action plan designed to address specified compliance weaknesses. Ratings →
Can a B-rated sponsor sponsor new workers? +
The guidance places restrictions on sponsoring new workers during the B-rated/action-plan period. Ratings →
Sponsor Licence suspension
Can a sponsor assign a CoS while the licence is suspended? +
No. A suspended Sponsor Licence cannot be used to assign new Certificates of Sponsorship. Suspension →
Are existing sponsored workers' visas cancelled as soon as the licence is suspended? +
No. Existing workers with valid permission aren't affected simply because of suspension unless and until further Home Office action affects their permission. Suspension →
How long does the sponsor have to respond to a suspension letter? +
The current guidance gives 20 working days from the date of the written notification (as at May 2026 — confirm against the suspension letter and latest guidance). Suspension →
Sponsor Licence revocation
Is revocation the same as suspension? +
No. Suspension restricts sponsorship activity while the Home Office considers compliance concerns; revocation terminates the licence. Suspension · revocation.
Can the Home Office revoke without suspending first? +
Yes. The guidance allows direct revocation where the applicable ground permits or requires it. Revocation →
What happens to sponsored workers if the Sponsor Licence is revoked? +
Their immigration permission can be affected. The precise treatment depends on the worker's circumstances and the reason for revocation — there's no single universal cancellation period. Revocation →
Can a revoked sponsor apply again? +
Potentially, but an applicable cooling-off restriction may apply, and a new application is assessed against the requirements in force at that time, including previous sponsorship history. Revocation →
Right to Work and civil penalties
Are Right to Work checks the same as Sponsor Licence duties? +
No. Right to Work compliance interacts with Sponsor Licence compliance, but the statutory check procedure belongs to a separate Home Office employer regime — the detailed Right to Work checking rules aren't in this source set and need separate Home Office employer guidance.
Are civil penalties covered by the Sponsor Licence guidance? +
The sponsor guidance can refer to illegal-working/civil-penalty issues when considering sponsor suitability, but the detailed civil-penalty regime comes from separate Home Office guidance and isn't covered here.
Some questions depend on the specific facts. Whether an application will be approved, a vacancy is genuine, a code is correct, a visit will pass, a licence will be revoked, TUPE applies, a worker can switch, or a business is compliant all turn on the particular circumstances — these FAQs point you to the factors to review and the owner page rather than a blanket yes/no.
