Skilled worker visa guidance for UK employers

Employers across the UK continue to rely on international talent to fill key roles, from tech and engineering to healthcare and hospitality. The skilled worker visa provides a structured route to hire qualified overseas staff — but it also places detailed compliance duties on sponsoring employers. Understanding these obligations is vital to avoid delays, refusals, or even the loss of your sponsor licence.

Whether you are applying for a sponsor licence for the first time or managing an existing one, our immigration solicitors can support you through each stage of the process — ensuring your business remains compliant and ready to employ the best talent from abroad.

Whatever industry you’re recruiting for, contact our solicitors for clear, practical advice on skilled worker visa applications and compliance.

Understanding the skilled worker visa route

The skilled worker visa sits at the core of the UK’s points-based immigration system. It allows licensed employers to sponsor non-UK nationals for eligible skilled roles, provided both the employer and the job meet strict criteria.

To qualify, the position must:

• Be a genuine vacancy at an eligible skill level — generally RQF Level 6 or above, following the latest October 2025 reforms.
• Offer a salary meeting or exceeding the current Home Office threshold or the going rate for that occupation.
• Be filled by an individual who meets the English-language and eligibility requirements.
• Employers must hold a valid sponsor licence before they can sponsor any worker under this route.

Employer sponsorship duties

Holding a sponsor licence brings ongoing compliance responsibilities. The Home Office expects sponsors to act with integrity, maintain accurate records, and monitor their sponsored employees throughout their employment.

Key duties include:

• Conducting right-to-work checks before employment begins.
• Keeping records of employment contracts, job descriptions, and salary details.
• Reporting changes such as promotions, role changes, or early terminations through the sponsor management system (SMS).
• Co-operating fully with Home Office compliance visits, including unannounced audits introduced under the October 2025 framework.

Failure to meet these duties can result in penalties, suspension, or revocation of the licence — potentially leaving sponsored workers without valid leave to remain.

Assigning a certificate of sponsorship

Once a licence is in place, the employer must assign a certificate of sponsorship (CoS) to each new hire. This electronic document confirms the details of the job and the sponsor’s authorisation.

There are two types of CoS:

• Defined CoS: used for overseas applicants applying from outside the UK.
• Undefined CoS: used for those already in the UK under a different visa route or for ongoing employment.

Accuracy is crucial. Errors in the job description, SOC code, or salary details can lead to refusal or delay. Employers should also ensure they have enough CoS allocations each year to meet recruitment needs

Meeting salary and skill level requirements

These thresholds are reviewed regularly. Following the October 2025 reforms (HC 1333), the general salary threshold remains £41,700, but the Home Office has expanded the Immigration Salary List (ISL) and tightened compliance conditions for discounted roles.

Employers must check that:

• The job’s SOC code appears on the current ISL or other eligible-occupation list.
• The salary offered meets both the general threshold and the going rate for that occupation.
• Any allowances or benefits used to reach the threshold comply with the rules.

Roles previously eligible under transitional July 2025 provisions may now require reassessment to ensure they still qualify under the updated ISL.

Failing to meet these salary or skill level criteria is one of the most common reasons for visa refusals.

Visa application process for employees

Once a CoS is assigned, the sponsored employee can apply for their visa online. Employers should be prepared to provide supporting documents and respond promptly to any Home Office queries.

Processing times typically range from three to eight weeks, depending on the applicant’s location and the service used. A new super-priority option introduced in October 2025 offers faster decisions in some cases.

Employers should avoid setting firm start dates until the visa has been approved to prevent potential breaches of immigration law.

Renewals, extensions, and changes

Sponsorship duties do not end once the visa is granted. Employers must continue to monitor each worker’s status and report key changes such as:

• Job title, duties, or salary adjustments.
• Changes in work location, including hybrid or remote arrangements.
• Termination of employment or long absences.

Since 6 April 2024, a sponsorship licence has been valid for ten years, following an automatic extension. Under the October 2025 compliance update, the Home Office may now conduct licence reviews at any time within that period. Employers must adhere to all sponsor responsibilities to avoid penalties.

Common pitfalls and compliance risks

Even experienced employers can fall foul of immigration compliance rules. Typical issues include:

• Late or incomplete reporting through the SMS.
• Assigning CoS to roles that do not meet the required skill or salary level.
• Poor record-keeping or missing documentation.
• Lack of internal oversight or training for staff managing the sponsorship process.

The October 2025 reforms introduced tiered civil penalties and wider powers for the Home Office to suspend CoS allocations where compliance concerns arise.

A proactive approach — including periodic internal audits and legal reviews — can prevent these risks and demonstrate compliance if inspected by the Home Office.

How immigration solicitors can help employers

Professional support can make the sponsorship process far smoother. Our immigration solicitors regularly assist employers with:

• Preparing for Home Office compliance visits.
• Conducting mock audits to identify potential issues.
• Advising on SOC code selection, salary calculations, and job descriptions.
• Challenging licence suspensions or refusals.

By partnering with experienced legal advisers, businesses can focus on recruitment and growth rather than administrative risk.
