The UK Sponsor Licence is an employer authorisation. Understanding what it permits, what it restricts, and how it interacts with the work rights of the individuals it sponsors is essential for both employers and the overseas workers they employ. The rules governing what a sponsored worker can and cannot do professionally are set out in the Skilled Worker Visa conditions, the Immigration Rules, and the Home Office's published sponsor guidance.
This article explains the work, employment, and self-employment rules that apply to workers sponsored under a UK Sponsor Licence, with a specific focus on the Skilled Worker route — the most common category. It covers what work is permitted, whether self-employment or freelancing is allowed, what happens when an employee changes jobs, and how side income and consulting arrangements are treated.
Work Rights Granted by This Visa
A worker sponsored under the Skilled Worker Visa route is granted leave to remain in the UK specifically to work for their sponsoring employer, in the role and at the location specified in their Certificate of Sponsorship. This is the fundamental structure of sponsored employment under the UK immigration system: the leave is granted for a specific purpose, with a specific employer, in a specific role.
This means the sponsored worker may work for their sponsoring employer in the sponsored role, including reasonable variations of that role within the same occupation code. They may work at different locations operated by the same employer. They may receive promotions, salary increases, and changes in seniority within the sponsored occupation without needing a new visa, provided the role remains within the same Standard Occupational Classification (SOC) code, and the salary continues to meet the applicable threshold.
The sponsored worker may not, however, work for a different employer without the new employer obtaining their own Sponsor Licence and issuing a new Certificate of Sponsorship. Working for an employer who is not a licensed sponsor — even informally, even on a short-term basis — is a breach of visa conditions and can result in curtailment of leave and consequences for future immigration applications.

Self-Employment and Freelance Permissions
The Skilled Worker Visa does not permit self-employment. A Skilled Worker Visa holder may not work as a sole trader, as a freelancer invoicing their own clients directly, or as a self-employed contractor outside their sponsoring employer relationship. Self-employment is a distinct work status from employment, and the Skilled Worker route explicitly requires the holder to be employed by a licensed sponsor in a qualifying role.
This is one of the most significant structural differences between the Skilled Worker Visa and the Global Talent Visa. Global Talent Visa holders have entirely unrestricted work rights — they may be employed, self-employed, a company director, a freelancer, or any combination of these, without restriction. Skilled Worker Visa holders are tied to their sponsoring employer and the sponsored role.
Employer Requirements (If Any)
The employer sponsoring a Skilled Worker must hold a valid Sponsor Licence issued by the Home Office and must assign a Certificate of Sponsorship to the worker before the visa application is submitted. The employer must pay the worker at least the minimum salary threshold for the sponsored role — currently £38,700 per year for most roles (as of April 2024), or the going rate for the specific occupation code if higher — and must continue to pay at or above this threshold throughout the period of sponsorship.
The employer must also notify the Home Office of certain changes in the worker's circumstances — including if the worker stops working for them, changes role significantly, or takes unpaid leave beyond a short permitted period. These reporting obligations are the employer's responsibility, not the worker's, but the immigration consequences of a sponsor's failure to report also fall on the sponsored worker.
If the Home Office revokes the sponsor licence — due to non-compliance with sponsor duties, a failed compliance visit, or other grounds — sponsored workers are given 60 days to find a new licensed sponsor and obtain a new Certificate of Sponsorship, or to make alternative immigration arrangements. A revocation does not immediately terminate the worker's leave, but it ends the sponsoring relationship and creates a 60-day window within which the worker must act.
Self-Employment and Freelance Allowed?
As noted above, the Skilled Worker Visa does not permit self-employment or freelance work outside the sponsored employment relationship. This is a firm restriction with no discretionary exceptions.
However, the following activities are generally considered permissible for Skilled Worker Visa holders and do not constitute prohibited self-employment:
Passive income: Income from investments, rental properties, dividends from shares, or interest on savings is not work income and is not restricted by the Skilled Worker Visa conditions. A sponsored worker who owns a rental property and receives rental income, or who holds shares and receives dividends, is not in breach of their visa conditions.
Directorship without remuneration: Being a director of a company — for example, a holding company for investment assets — is generally permissible provided the directorship does not involve active trading, does not generate employment income for the visa holder, and does not represent a separate occupation. Legal advice should be sought before taking on any directorship to confirm it does not breach the sponsored worker conditions.
Voluntary work: Volunteering for a charity or community organisation — provided it is genuinely unpaid and not displacing paid employment — is generally permissible and not considered a breach of Skilled Worker Visa conditions.
Writing, speaking, and media: Sponsored workers who receive occasional fees for speaking at conferences, writing articles, or media appearances should seek advice on whether this constitutes secondary employment. One-off or occasional payments that are incidental to the primary employment are generally lower risk; regular income from a separate professional activity is higher risk and should be assessed.
The sponsoring employer must maintain a valid Sponsor Licence throughout the period of the worker's sponsored leave. If the licence expires, is suspended, or is revoked, the sponsored worker's leave is not automatically terminated, but the sponsoring relationship ends, and the Home Office must be notified.
The employer must continue to pay the worker at or above the applicable salary threshold. If the worker's salary falls below the threshold, for example, due to a role change, reduced hours, or unpaid leave, the employer must notify the Home Office, and the worker's leave may be curtailed.
The employer must ensure the worker is actually performing the sponsored role. Assigning a Certificate of Sponsorship for a role the worker will not actually perform — sometimes called "ghost sponsorship" is a serious breach of sponsor duties that can result in licence revocation and criminal prosecution.
Switching Employer or Career
Switching Employer or Career
A Skilled Worker Visa holder who wishes to change employer must have their new employer obtain their own Sponsor Licence — if they do not already hold one; and assign a new Certificate of Sponsorship for the new role. The worker must then make a new visa application (a further leave to remain application, not a fresh entry clearance application if already in the UK) before beginning work for the new employer.
The worker may not begin working for the new employer before the new Certificate of Sponsorship has been assigned, and a valid further leave to remain application has been submitted. The section 3C leave provisions, which allow a worker to continue working while a renewal application is pending, apply once the new application is submitted, not from the point at which the old employer relationship ends.
Changing occupation code: Moving to a role under a different SOC code is permissible provided the new employer holds a Sponsor Licence for that code, and the new role meets all the eligibility requirements for the Skilled Worker route, including the applicable salary threshold and going rate. Some occupation codes have higher going rates than others; the worker and employer should confirm the applicable rate before proceeding.
Gap between employers: There is no formal grace period for a Skilled Worker Visa holder who leaves one employer before the new employer's Certificate of Sponsorship is in place. The holder's leave remains valid — it does not expire immediately upon leaving employment, but working without a valid CoS is a breach of conditions. Workers should aim to have the new CoS in place before leaving their current employer, and should take legal advice if a gap is unavoidable.
Tax and Side-Income Considerations
The Skilled Worker Visa permits supplementary employment in specific circumstances, but the rules are narrow and frequently misunderstood.
Supplementary employment is permitted if it is in the same occupation code as the sponsored role, or in a shortage occupation, is with a licensed sponsor, and does not exceed 20 hours per week. This is a specific carve-out designed for workers who wish to take on a second employed position.
This means a Skilled Worker Visa holder whose primary role is as a software engineer (SOC code 2135) may take on a second employed position in the same or a shortage occupation, provided that second employer is a licensed sponsor and the total secondary employment does not exceed 20 hours per week. They may not, however, take on freelance software engineering work invoiced directly to clients.
Multiple jobs with the same employer: A worker who holds more than one role with their sponsoring employer, for example, an employment contract for a primary role and a separate arrangement for occasional teaching or internal consulting, should ensure both roles are clearly documented in their sponsorship arrangements and do not create compliance issues for the employer.
Tax on side income: All income earned in the UK — whether from employment, supplementary employment, or permissible passive sources is subject to UK income tax under HMRC rules. Sponsored workers who receive income from multiple sources should ensure they are registered with HMRC appropriately and filing self-assessment returns where required. HMRC's tax obligations are entirely separate from the Home Office's immigration conditions, but a worker whose tax affairs are not in order may face complications at the ILR stage, where good character is assessed.
UK income tax applies to all employment income earned in the UK, regardless of immigration status. Skilled Worker Visa holders are taxed in the same way as UK citizens and settled residents — through the Pay As You Earn (PAYE) system for employment income, and through self-assessment for any income not covered by PAYE.
National Insurance contributions are also mandatory for most employed workers in the UK, including those on Skilled Worker Visas. Contributions count towards the UK state pension and certain benefits entitlements, though the practical value of these entitlements for non-settled workers depends on the length of stay and future intentions.
Sponsored workers who have income arising in another country, for example, from property, investments, or a business retained in their country of origin, should take advice from a qualified tax adviser on their UK tax obligations. The UK has double taxation treaties with many countries that may reduce or eliminate double taxation on cross-border income. Still, the specific treatment depends on the nature of the income and the relevant treaty.
The Immigration Skills Charge — paid by the employer when assigning a Certificate of Sponsorship is not a tax on the worker and is not deductible from the worker's salary.
Job-Seeker Route After Arrival
There is no formal "job-seeker" visa category in the UK. A Skilled Worker Visa holder who loses their job — whether through redundancy, resignation, or dismissal; does not automatically have a period of leave in which to seek new employment in the same way that some other immigration systems provide.
Upon leaving sponsored employment, the worker's leave does not immediately expire, but the basis for their leave — the Certificate of Sponsorship and the employment relationship has ended. The Home Office may curtail leave if it becomes aware that the employment has ended and no new sponsoring relationship is in place.
In practice, the Home Office does not monitor individual employment relationships in real time, but the sponsoring employer is required to notify the Home Office when a sponsored worker leaves their employment. From the date of that notification, the worker should treat their position as time-limited and seek alternative immigration arrangements promptly.
Options for a worker who has lost sponsored employment: If the worker can find a new licensed sponsor promptly, a further leave to remain application based on the new Certificate of Sponsorship resolves the situation. If the worker's profile supports an application for the Global Talent Visa, which requires no employer sponsor, this may be a stronger long-term option, as it removes the dependency on employer sponsorship entirely. If the worker has accrued five years of continuous lawful residence and meets the ILR requirements, an immediate ILR application may be the most efficient resolution.
