UK Skilled Worker Visa Sponsor Licence Explained
How a UK employer's sponsor licence connects to a Skilled Worker visa applicant through a Certificate of Sponsorship, and why current Home Office guidance needs confirming before relying on it.
A quick but important note before anything else: the UK's sponsor licence and Skilled Worker visa framework is set by the Home Office and administered by UK Visas and Immigration, and its fees, salary thresholds, points requirements, and processing times are reviewed and revised on an ongoing basis. This article describes the general structure of how sponsor licences and the Skilled Worker route fit together — it does not state any specific current fee, salary threshold, points total, or processing time as fact, because none of those figures are fixed and repeating a stale one could genuinely mislead an employer or applicant. Always confirm current requirements directly on GOV.UK, or with a registered immigration adviser, before relying on any of this for a specific case.
For a consultancy that advises both individual visa applicants and the UK employers looking to hire them, the sponsor licence is one of the least understood parts of the Skilled Worker route — largely because it sits on the employer's side of the process rather than the applicant's. Getting the underlying structure right matters, because whether an employer already holds a valid licence, or needs to apply for one, is generally the first question that determines whether a Skilled Worker visa application is even possible for a given candidate.
Why the licence sits with the employer, not the worker
The UK's Skilled Worker route is generally built around the idea that an employer, not the individual worker, takes on responsibility for sponsorship. A UK employer wanting to sponsor a Skilled Worker visa applicant generally must first hold a valid sponsor licence issued by UK Visas and Immigration, a part of the Home Office. A prospective employee generally cannot sponsor themselves — the employer is the party that applies for, and holds, the licence, and it is the employer's compliance record that the Home Office monitors on an ongoing basis, not the individual worker's. This is a structural feature of the route worth explaining clearly to candidates, because it means a consultancy is often advising two different parties — the worker and the employer — with different obligations under the same overall framework.
The employer holds the licence, not the worker
A UK employer generally must hold a valid sponsor licence, issued by UK Visas and Immigration (part of the Home Office), before it can sponsor anyone for a Skilled Worker visa. A worker generally cannot sponsor themselves — the employer applies for, and holds, the licence.
The licence application is a compliance check, not a formality
An employer applying for a sponsor licence is generally expected to demonstrate a genuine need for the role being sponsored, suitable HR systems for tracking sponsored workers, and to pass a Home Office review of its processes — not simply fill in a form.
A Certificate of Sponsorship links the employer to the worker
Once licensed, an employer can generally assign a Certificate of Sponsorship (CoS) to a specific worker for a specific role, which the worker then generally uses as part of their own Skilled Worker visa application, alongside the visa's own separate eligibility requirements.
The licence carries ongoing duties, not a one-time approval
Holding a sponsor licence generally comes with continuing reporting duties to the Home Office, and a licence that is revoked or downgraded for non-compliance can generally affect every worker that employer currently sponsors — not just future applications.
Applying for a sponsor licence: genuine need, HR systems, and compliance
An employer applying for a sponsor licence is generally expected to demonstrate more than a wish to hire from overseas. The Home Office review process generally looks at whether the employer has a genuine need for the role or roles it wants to sponsor, whether it has suitable HR systems in place for tracking sponsored workers and monitoring their circumstances, and whether the organisation itself is suitable to be trusted with sponsorship responsibilities in the first place. This is generally described as a compliance-oriented process rather than a simple registration — the Home Office can, and generally does, carry out checks on an applicant employer before a licence is granted. The exact documentation and evidence expected, and how that process is currently run, is set out in Home Office sponsor guidance and should be confirmed there, or with a registered immigration adviser, rather than assumed from general knowledge.
Sponsor ratings: a general concept, not fixed terminology
Sponsor licences have generally been categorised by a rating reflecting how well the sponsor is meeting its compliance obligations — historically discussed in terms of an "A-rating" for a sponsor in good standing, and a "B-rating" or action-plan status for a sponsor the Home Office has identified as having compliance issues that need to be corrected, sometimes within a set period, before the sponsor can return to full standing. It's worth being direct that this article treats rating names and mechanics as a general concept rather than fixed, current fact — the terminology, the consequences of a downgrade, and the process for addressing compliance issues are set by Home Office policy and have been revised before. A consultancy advising an employer on its rating, or on a compliance visit, should check the current framework directly against Home Office sponsor guidance rather than relying on a description from a previous year.
From licence to worker: the Certificate of Sponsorship
Once an employer holds a valid sponsor licence, it can generally assign a Certificate of Sponsorship (CoS) to a specific worker for a specific role. The CoS is generally what the worker then uses as part of their own Skilled Worker visa application — it is a record linking that worker to that employer and that role, not the visa itself. The worker generally still needs to separately meet the Skilled Worker visa's own eligibility requirements, which can include factors such as the skill and salary level associated with the sponsored role and the applicant's English language ability, among others set by current Home Office rules. This article deliberately does not attempt to state any of those requirements as a fixed number or threshold, since they are exactly the kind of detail that is reviewed and revised over time, and a consultancy should confirm what currently applies before advising a specific candidate.
Ongoing compliance duties after the licence is granted
Holding a sponsor licence is generally not a one-time approval — it generally comes with continuing duties that last for as long as the licence is held. A licensed sponsor is generally expected to report certain changes in a sponsored worker's circumstances to the Home Office, such as unexplained absence from work, a change in the worker's role or salary, or the end of their employment with the sponsor, along with maintaining records and carrying out right-to-work checks. A sponsor that fails to meet these duties can generally have its licence downgraded, suspended, or revoked, and because a worker's ability to remain on the Skilled Worker route is generally tied to their sponsor's licence remaining valid, a compliance failure on the employer's side can directly affect the worker being sponsored — not just the employer's ability to sponsor future hires.
What this means for advising employer clients, not just applicants
A consultancy that only tracks the applicant's side of a Skilled Worker case is generally missing half the picture, because the employer's licence status, its rating, and its ongoing reporting duties are all facts that can affect whether a case can proceed at all. Our UK visa consultant software page covers how VisaBOS helps a consultancy track UK cases — including employer sponsor details alongside the applicant's own case record — on one connected system, though it is a case-management tool and not a source of current immigration policy, so it does not replace confirming live requirements with the Home Office. If your consultancy is also advising Skilled Worker applicants on what happens after the visa is granted, our companion piece on the UK Graduate Route visa covers a related but separate post-study pathway, and our guide to the UK Immigration Health Surcharge is worth reviewing since it applies across most UK visa categories, including the Skilled Worker route.
To be direct about what this article will not do: it will not state a specific current sponsor licence fee, Skilled Worker salary threshold, points total, or processing time as fixed fact, because none of those figures stay fixed for long, and a consultancy repeating a stale one to an employer or applicant could genuinely cause harm to a real case.
Frequently asked questions
Who actually applies for a UK sponsor licence — the employer or the worker?
The employer applies for, and holds, the sponsor licence. A prospective Skilled Worker visa applicant generally cannot sponsor themselves; they need a UK employer that already holds a valid sponsor licence, or one that is willing to apply for and obtain one, before that employer can assign a Certificate of Sponsorship to them. This distinction matters for a consultancy advising individual candidates, because part of the advice process is generally establishing whether the prospective employer is already a licensed sponsor, or whether a licence application needs to happen first — and that timeline is a separate process from the worker's own visa application.
What does a UK employer generally need to show when applying for a sponsor licence?
A UK employer applying for a sponsor licence is generally expected to demonstrate a genuine need for the role or roles it wants to sponsor, evidence of suitable HR systems and right-to-work checking processes for tracking sponsored workers, and to satisfy the Home Office that its organisation is suitable to hold sponsorship responsibilities. This is a general description of the underlying concept rather than a checklist of current requirements — the exact documentation, evidence, and process UK Visas and Immigration expects is set out in current Home Office guidance and should be confirmed there, or with a registered immigration adviser, before an employer begins its application.
What is a sponsor rating, and does it matter for the workers being sponsored?
Sponsor licences have generally been categorised by a rating that reflects the Home Office's assessment of how well a sponsor is meeting its compliance duties — historically referred to in terms such as an "A-rating" for a compliant sponsor, and a "B-rating" or action-plan status for a sponsor found to have compliance issues that need addressing before it can return to full standing. This article describes the general concept rather than fixed, current terminology or mechanics, because rating names, thresholds, and consequences are set by Home Office policy and can be revised. A consultancy should confirm the current rating framework, and what a downgrade means in practice, against current Home Office guidance rather than relying on a description from a prior year.
What is a Certificate of Sponsorship, and is it the same thing as the visa?
A Certificate of Sponsorship (CoS) is generally a record, assigned by a licensed employer to a specific worker for a specific role, that the worker then uses as part of their own Skilled Worker visa application. It is not itself the visa — the worker generally still needs to meet the Skilled Worker visa's own separate eligibility requirements, which can include factors such as the skill and salary level of the role and English language ability, and this article deliberately does not attempt to state any of those as a fixed current figure or threshold, since they are set and periodically revised by the Home Office.
What happens to a sponsored worker if their employer loses its sponsor licence?
If a sponsor licence is revoked or the sponsor otherwise stops being able to sponsor a worker, this generally affects that worker's ability to remain on their current visa route through that employer, and the worker may generally need to find a new licensed sponsor within a period set by the Home Office, or otherwise regularise their status, depending on their circumstances. Because the consequences and any applicable timeframes are set by current Home Office policy and can change, a consultancy supporting an affected worker or employer should treat this as a case requiring immediate, current guidance from GOV.UK or a registered immigration adviser rather than general assumptions.
What ongoing duties does a sponsor take on after the licence is granted?
A licensed sponsor generally takes on continuing reporting duties to the Home Office about changes affecting a sponsored worker's circumstances — for example matters such as unexplained absence, a change in the worker's role or salary, or the end of their employment — along with record-keeping and right-to-work checking obligations that continue for as long as the licence is held. These are generally described in current Home Office sponsor guidance in more specific terms than this article covers, and a consultancy advising an employer client should point them to that current guidance, since reporting duties and deadlines are exactly the kind of detail that changes and needs verifying rather than assumed.
