Switching Employers on a Sponsored Work Visa UK 2026

If you hold a UK Skilled Worker visa and want to change jobs, your visa does not travel with you automatically — it is tied to your current licensed sponsor. You must secure a new Certificate of Sponsorship from your prospective employer and submit a fresh visa application to UK Visas and Immigration (UKVI) before you can legally start work for anyone new.

This guide is written for sponsored workers navigating an employer change in 2026. It covers the full sequence of steps, the obligations that fall on your new employer, the mistakes that derail switches, and the situations where you genuinely need professional immigration advice.

Why Your Visa Is Employer-Specific

When you were granted a Skilled Worker visa, UKVI approved you to work for a named sponsor in a specific role defined by a Standard Occupational Classification (SOC) code. That permission does not extend to other employers — even if the job title, salary, and sector are identical.

This matters because many workers assume that because they are legal residents in the UK, they can simply take another job. That assumption is wrong and can have serious consequences: working for an unauthorised employer is a breach of your visa conditions, which could lead to curtailment of your leave, a bar on re-entry, or, in serious cases, enforcement action.

The good news is that the UK's Skilled Worker route is designed to be portable. The system allows you to switch without leaving the country, provided the process is followed correctly.

The Step-by-Step Process for Switching Employers

Step 1 — Confirm the New Employer Holds a Valid Sponsor Licence

Before you go any further in the recruitment process, verify that your prospective employer is on the Home Office's register of licensed sponsors. This is a publicly searchable list at gov.uk. An employer who is not on the register cannot legally assign you a Certificate of Sponsorship, full stop. You can learn how to run this check in our guide on how to check if a company holds a sponsor licence.

If the employer you want to work for is not yet licensed, they would need to apply for a sponsor licence before they could hire you — a process that typically takes several weeks at minimum, though timescales vary. For context on how long that takes, see our article on the UK sponsor licence application timeline.

Step 2 — Secure a Job Offer That Meets Skilled Worker Requirements

Not every job at a licensed employer qualifies for Skilled Worker sponsorship. The role must:

• Be assigned an eligible SOC code (broadly, RQF Level 3 or above)
• Meet the applicable minimum salary threshold — either the general threshold or the going rate for that SOC code, whichever is higher
• Be a genuine vacancy

Salary thresholds have changed more than once in recent years. Always check the current thresholds on the gov.uk Skilled Worker visa page before assuming a salary will qualify. If your occupation appears on the Immigration Salary List, a different (and sometimes lower) threshold may apply — but this list is subject to review. Verify its current status officially.

Before accepting any offer, read our guide on what to check before accepting a sponsored job offer. It covers the questions you should ask — and answers you should get in writing — before you commit.

Step 3 — The New Employer Assigns a Certificate of Sponsorship

Once you have a confirmed offer, the employer's authorising officer or key contact logs into the Sponsor Management System (SMS) and assigns you a Certificate of Sponsorship (COS). This is not a physical document — it is an electronic record with a unique reference number.

The COS will specify:

• Your name and personal details
• The SOC code and job title
• The salary
• The start date and duration of the role

You will need the COS reference number to make your visa application. For a detailed breakdown of what a COS contains and how employers assign one, see our guide on the Certificate of Sponsorship explained for employers.

One important point: the COS must be assigned before you submit your visa application. You cannot apply first and supply the reference number later.

Step 4 — Submit Your In-Country Visa Application

With the COS reference number in hand, you apply online via the UKVI application portal. This is technically an application to vary your leave — you are not applying for a brand-new visa from scratch, but you are applying for permission to work for a new sponsor.

You will need to pay:

• The visa application fee (currently variable based on the length of leave and whether the role is on the Immigration Salary List — check the current fee schedule at gov.uk/visa-fees)
• The Immigration Health Surcharge (IHS), unless you are exempt

Your new employer will separately pay the Immigration Skills Charge — this is their cost, not yours, and it is illegal for them to pass it on to you. The charge is paid at the point the COS is assigned.

Supporting documents typically required include your current BRP or eVisa, passport, COS reference number, evidence of English language proficiency (unless exempt), and financial evidence if applicable. Check the specific document list on gov.uk for your circumstances, as requirements can vary.

Step 5 — Do Not Start Work Until You Have Approval

This cannot be overstated. You must not begin work for the new employer until UKVI has approved your application and you have valid permission to work for that sponsor. Starting work before approval is a breach of your visa conditions.

If you are worried about the gap between leaving your current employer and your new visa being approved, this is precisely the situation where you should take advice from a licensed immigration solicitor or an OISC-regulated adviser rather than guessing.

What Your Current Employer Must Do

When you resign, your current employer is legally required to report your departure to the Home Office via the Sponsor Management System. This is one of their core compliance duties as a licence holder. Once they report it, the Home Office will typically curtail your existing leave — meaning your current visa will be given an end date, often aligned to the date your employment ends or shortly after.

This is why timing matters. If your new visa application is already approved or in progress when this happens, the curtailment may be academic. If it is not in progress, you will be working against a hard deadline. Do not leave a wide gap between your current role ending and your new application being submitted.

For employers reading this section: failing to report a leaver promptly is a compliance breach that can result in your licence being downgraded or revoked. Reporting duties are covered in detail in our sponsor licence compliance duties guide.

Illustrative Example: How a Switch Works in Practice

This example is illustrative only and uses approximate figures. It does not represent any real individual and should not be treated as advice.

Amara holds a Skilled Worker visa valid until March 2028. She is employed as a data analyst (SOC code 2425) at a mid-sized logistics firm at £38,000 per year. She receives an offer from a financial services company at £47,000 per year for a similar role.

1. Amara checks the register of licensed sponsors — the new employer is listed.
2. The new employer's HR team assigns a COS via the SMS for the data analyst role at £47,000, ticking all the salary and SOC requirements.
3. Amara receives the COS reference number and submits her in-country variation application, paying the applicable fee and IHS.
4. She gives notice to her current employer and agrees a leaving date four weeks away.
5. Her current employer reports her departure via SMS the day she leaves.
6. UKVI approves her application (under the standard timeline published on gov.uk) before her current employer's report triggers a curtailment action.
7. Amara begins work for the new employer on the agreed start date, which is after her new permission is confirmed.

The key factor here: Amara submitted her application before giving notice, and her new start date was timed conservatively to give UKVI time to process. This kind of sequencing is what prevents gaps.

If she were switching into accountancy, she might also find our guide to accountant jobs in the UK with visa sponsorship useful for understanding what employers in that sector typically offer sponsored workers.

What the New Employer Needs to Know

Employers often underestimate the cost and administrative work of hiring someone who is switching sponsors. Here is a summary of their obligations:

Employers new to sponsorship sometimes underestimate the ongoing compliance burden. Our guide on hiring international workers and employer obligations covers the full picture. For smaller businesses thinking about whether the cost and administration is manageable, the small business guide to sponsoring overseas staff is a practical starting point.

Common Mistakes — and How to Avoid Them

1. Starting work before the new visa is approved. Fix: treat your new start date as provisional until you have written confirmation from UKVI. Build buffer into your notice period and negotiations with the new employer.

2. Accepting a job where the salary is just below the threshold. Fix: check the current salary thresholds and the going rate for the specific SOC code on gov.uk before formally accepting. A small shortfall disqualifies the application entirely.

3. Assuming the new employer can sponsor because they are large or well-known. Fix: always search the register of licensed sponsors. Size and reputation do not equal a licence. Companies lose their licences, and new employers may never have applied.

4. Not telling the new employer about processing times. Fix: share the current UKVI standard processing time (published at gov.uk/check-immigration-status) with HR early. Many employers assume switches happen in days. Unrealistic start dates create pressure that leads to compliance errors.

5. Letting the current employer's HR report the departure before the new application is submitted. Fix: be transparent with your current employer about timing. There is no obligation to leave on a specific date; notice periods are contractual, and you have some control over when your departure is formally logged in the SMS.

6. Accepting a role where the SOC code does not match the actual work. Fix: if the employer assigns a COS with a SOC code that does not genuinely reflect what you will be doing, this is a compliance risk for them and an immigration risk for you. Raise it. If in doubt, get independent advice from an OISC-regulated adviser.

7. Paying a recruiter or agent for help securing the sponsorship. Fix: no legitimate employer or agent charges a worker for a job or a visa. If anyone asks you to pay for a Certificate of Sponsorship or a job placement, walk away and report it.

Scenarios Where You Should Always Take Professional Advice

The general process above covers the straightforward case. But some situations genuinely require input from a licensed immigration solicitor or an OISC-regulated adviser:

• You have been made redundant unexpectedly and are working against a curtailment deadline.
• Your visa has already expired or is close to expiry and you are mid job search.
• The new role involves a significant change in SOC code and you are unsure whether it still qualifies.
• You have had previous immigration refusals or any enforcement history.
• You are on a visa that has conditions beyond standard Skilled Worker terms (e.g. conditions attached to your original entry clearance).
• The new employer's licence is very recently granted and they have not yet sponsored anyone — their processes may need guidance.

Sectors Where Switching Is Most Common

Employer switching is prevalent across a wide range of sponsored roles in the UK. Workers in care and health frequently find themselves seeking new sponsors when an employer closes a service or loses their licence. If you work in the care sector, our guide to care assistant jobs in the UK with visa sponsorship covers the landscape of employers who actively sponsor in that field.

In technology, switching between employers is arguably the most common use of the Skilled Worker route's portability. If you are exploring your options in that sector, take a look at our overview of tech and software firms that sponsor international hires.

For workers considering switching not just employers but countries entirely, the processes differ substantially — each country has its own sponsorship framework. Our guides to roles in Europe and further afield can help you understand the different landscapes involved.

A Note on Salary Negotiations During a Switch

When switching employers, the salary on your new COS is the salary UKVI will assess against the thresholds. It must meet the going rate for the SOC code and the general minimum — whichever is higher. You cannot negotiate a lower salary in exchange for other benefits and then have the COS show a higher figure. The salary on the COS must reflect what you will actually be paid.

This matters particularly if you are negotiating hybrid arrangements — for example, a base salary plus commission or bonuses. UKVI's salary assessment is based on guaranteed basic pay, not on-target earnings or variable components. Confirm this with the employer's HR team and, if necessary, with an immigration adviser before the COS is assigned.

Keeping Your Options Open: Building a Portable Career

The most practically useful mindset for a sponsored worker is to treat your immigration status as something you actively manage, not something that just happens to you. This means:

• Keeping copies of all your immigration documents, COS reference numbers, and correspondence with UKVI.
• Monitoring your visa expiry date and building in adequate time if you expect a switch.
• Staying informed about changes to the Skilled Worker route, salary thresholds, and the Immigration Salary List — these change, sometimes with relatively short notice.
• Understanding that if you want to change your working pattern substantially (for example, move to part-time), your employer may need to report this change and you may need to vary your leave.

The visa sponsorship application process end to end guide gives a useful grounding in how the overall system fits together, which helps you anticipate the administrative steps involved in any future change.

Summary: What You Need Before You Move

To switch employers lawfully on a UK Skilled Worker visa, you need three things confirmed before your first day with the new employer:

1. A job offer at a salary and SOC code that meets current Skilled Worker requirements — verified against the official thresholds on gov.uk, not against what you heard from a friend or read in an outdated article.
2. A Certificate of Sponsorship assigned by a licensed sponsor — with a reference number you have received directly.
3. A valid, approved visa variation — confirmed in writing by UKVI before you start work.

Everything else — the notice period, the start date, the onboarding — should be sequenced around these three requirements, not the other way around.
