UK Work Permits and Visas

In order to enter and work in London or the rest of the UK, you will need a UK Work Permit or visa. How difficult the application process for a UK Working Visa will depend on your personal circumstances.

To apply for a Work Permit UK, you will need to hold a formal job offer from a company with a valid sponsorship license. There is also an opportunity to enter the country on so-called ‘shortage occupations’. This can make your application easier and cost less in Home Office fees. There are several categories of Work Permits in the UK on offer for non-EEA citizens. The type of UK Work Visa you require will depend on your career, the amount of time you expect to spend in the UK, the UK work permit requirements and demand for your chosen position.

A large number of companies offer work permits in the UK and the government produce a list of all organisations that currently hold a valid Sponsor Licence which allows them to recruit overseas staff. The industries offering work permit sponsorship vary and range from care providers to international technology firms.

Document & Evidence Checklist for Applicants

Submitting a complete and well-organised application is one of the most effective things you can do to avoid delays and refusals.

• Proof of English language ability
• Tuberculosis (TB) test certificate (if you are from a listed country)
• Bank statement or financial evidence showing sufficient funds to support yourself upon arrival, unless your sponsor is an A-rated licensed sponsor who certifies maintenance
• Proof of qualifications
• UKVI application form (online) and payment confirmation
• Biometric Residence Permit (BRP) or eVisa

Additional Documents for Specific Circumstances

Top 10 Common Refusal Reasons & How to Avoid Them

A UK work visa refusal can be devastating as not only does it delay your plans, but certain refusals can affect future applications and, in some cases, result in you being barred from re-applying for a period of time. Understanding why applications are refused, and taking proactive steps to address those risks, is the most effective thing you can do before you submit.

1. Salary Does Not Meet the Required Threshold –  Incorrect calculation of the applicable going rate for the SOC code remains the single most common cause of refusal.

2. Certificate of Sponsorship Not Valid or Withdrawn – A CoS that has expired, been withdrawn by the sponsor, or does not match the details in the application will result in refusal.

3. English Language Requirement Not Met  – Submitting the wrong type of test, an expired result, or a score below the required level is a frequent reason for refusal.

4. Insufficient Funds / Maintenance Not Demonstrated – Where the sponsor does not certify maintenance, applicants must demonstrate they hold sufficient funds. Funds must have been held for 28 continuous days.

5. Role Does Not Meet RQF Level 6 – Applications submitted for roles no longer eligible under the skill threshold introduced on 22 July 2025 will be refused.

6. Genuine Vacancy Test Not Satisfied – The Home Office must be satisfied that the role is a genuine vacancy that a resident worker could not fill. Vague job descriptions, salaries that undercut industry norms, or employers with compliance issues may face greater scrutiny.

7. Sponsor Licence Suspended or Revoked -If your sponsor’s licence is suspended or revoked after your application is submitted but before a decision is made, your application will be refused.

8. Character or Criminality Concerns –  Unspent convictions particularly for certain serious offences can result in refusal.

9. Previous Visa Refusals or Immigration Breaches Not Declared – Failure to declare a previous refusal, overstay, or removal is treated as deception and will result in refusal and potentially a ban on future applications.

10. Documents Unclear, Untranslated, or Inconsistent –  Applications where documents are low quality, not in English without a certified translation, or contain inconsistencies, for example, different names across documents — are at elevated risk of refusal.

Recent Policy Changes and Upcoming Rule Updates

The UK’s work visa system has changed significantly since mid-2025, and anyone applying now, or planning to apply soon, needs to understand what has shifted and what may still be coming.

The most substantial change took effect in July 2025. The minimum skill level for the Skilled Worker visa rose from RQF Level 3 to RQF Level 6, which is the equivalent of graduate-level work. This removed more than 100 occupations from eligibility for new applicants.

Salary thresholds also increased  with the general minimum salary for Skilled Worker visa sponsorship rising from £38,700 to £41,700.  While the threshold for new entrants and roles on the Immigration Salary List increased  to £30,960.

Your role must meet whichever figure is higher: the general threshold, or the going rate for your specific occupation code.

English language requirements have also tightened. As of January 2026, first-time Skilled Worker applicants must demonstrate English at B2 level, up from the previous B1 standard. This applies to new applications rather than those extending an existing visa, but it is worth factoring into your planning well in advance, as approved English language tests must be taken at a recognised test centre.

Looking further ahead, the Government’s 2025 Immigration White Paper proposes extending the standard qualifying period for Indefinite Leave to Remain from five years to ten years under what the Home Office calls an “Earned Settlement” model.

At the moment. the five-year ILR route remains in force, and the Home Office is reviewing consultation responses, with implementation targeted for autumn 2026.

If you are currently eligible or will become eligible before any change takes effect, this is an important reason not to delay your application.

If you are unsure how these changes affect your specific situation, speaking with one of our immigration advisers is the safest first step.

Sponsor Licence: Employer Compliance Checklist

If you are a UK employer sponsoring overseas workers, holding a sponsor licence is only the beginning. The Home Office expects licence holders to maintain ongoing compliance with a detailed set of duties, and it conducts both announced and unannounced audits to check that those duties are being met. Failing an audit can result in your licence being downgraded, suspended, or revoked entirely, which can leave your sponsored employees without valid immigration status.

Your core responsibilities as a sponsor centre on the following:

• keeping accurate records
• reporting changes promptly
• ensuring every sponsored role continues to meet the relevant salary and skill requirements

In terms of record-keeping, you are required to hold up-to-date contact details, right-to-work check evidence, and employment records for every sponsored worker on your books. These must be readily accessible if an audit team requests them.

You should also audit every sponsored worker’s payroll and confirm that no pay period falls below the salary stated on their Certificate of Sponsorship, taking into account any deductions, salary sacrifice arrangements, or changes to contracted hours. A shortfall, even a temporary one, can be treated as a breach of your sponsor duties.

On reporting, you must notify the Home Office through the Sponsor Management System (SMS) within ten working days of a number of trigger events. These include a sponsored worker failing to turn up for their first day of work, being absent from work without permission for ten or more consecutive working days, having their employment terminated early, or changing the location, role, or hours of their sponsored position beyond what was set out in the original Certificate of Sponsorship.

Common audit findings include payroll records that do not match CoS salaries, expired or incomplete right-to-work checks, incorrect Standard Occupational Classification codes, outdated HR contact details on the SMS, and a failure to track visa expiry dates. Each of these is avoidable with the right internal systems in place. We recommend maintaining a centralised compliance log that covers right-to-work checks, absence monitoring, salary reviews, and visa expiry dates for every sponsored worker, reviewed at least quarterly.

Falling to a B-rating following an audit gives you a set period to put things right, but your ability to issue new Certificates of Sponsorship will be restricted during that time. Revocation is the most serious outcome, and recovering from it is a lengthy and uncertain process. Getting compliance right from the outset is significantly easier than remedying it afterwards.
