Skilled Worker Visa for Employers 2026: Sponsorship Guide

Overview

Hiring international talent through the UK's Skilled Worker visa route involves more than posting a job and making an offer. As an employer, you take on specific legal obligations from the moment you apply for a sponsor licence through to the end of each worker's sponsorship period. The rules have changed significantly since July 2025, with higher salary thresholds, stricter skill level requirements, and increased fees across the board.

This guide walks through the full employer journey: from deciding whether you need a sponsor licence, to understanding salary requirements, managing costs, and meeting your ongoing compliance duties.

Do You Need a Sponsor Licence?

Before you can sponsor anyone on the Skilled Worker route, your business must hold a valid sponsor licence issued by UK Visas and Immigration (UKVI). Without one, you cannot assign a Certificate of Sponsorship, and your prospective employee cannot apply for a visa.

Who needs one

Any UK-based employer that wants to hire a non-UK or non-Irish national who does not already have the right to work in the UK through another route (such as settled status, a Graduate visa, or a spouse visa with work rights) will need a sponsor licence.

What the Home Office looks for

The Home Office assesses whether your business is genuine and operating lawfully, whether it has the financial viability to support the sponsored role, and whether you have appropriate HR systems to meet ongoing sponsor duties. They also check that your key personnel (Authorising Officer, Key Contact, and Level 1 User) are suitable for their roles.

How long it takes

A standard sponsor licence application takes approximately 8 weeks. A priority service is available for around 10 working days, though this is subject to availability. Compliance visits are possible, particularly for newer businesses, those in certain sectors, or first-time applicants.

Understanding Salary Requirements

The salary rules for Skilled Worker sponsorship changed significantly on 22 July 2025. As an employer, the salary you offer on the Certificate of Sponsorship must meet multiple tests simultaneously.

The dual threshold

Every sponsored role must meet both:

1. The general salary threshold: £41,700 per year (or £17.13 per hour based on a 48-hour week)
2. The going rate for the specific SOC code: Each of the 412 eligible occupation codes has its own going rate, set using data from the Annual Survey of Hours and Earnings

The worker must be paid whichever figure is higher. For many roles, particularly in healthcare, construction, and specialist trades, the going rate exceeds the general threshold.

Reduced rates

Not every hire needs to meet the full £41,700. Reduced thresholds apply in specific circumstances:

• New entrants (under 26, switching from a Student or Graduate visa, or in certain postdoctoral roles): the minimum drops to £33,400, or 70% of the going rate
• Immigration Salary List (ISL) roles: a 20% discount on the going rate applies, though the general threshold still stands
• Health and Care Worker visa: separate, lower thresholds apply for eligible health and care roles

Why this matters for employers

Getting the salary wrong is one of the most common reasons for Skilled Worker visa refusals. The calculation is not always straightforward: pro-rata adjustments for part-time roles, different tables for different routes and dates, and transitional arrangements for existing visa holders all add complexity. Many employers discover at the Certificate of Sponsorship stage that the salary they planned to offer falls short of the going rate for the relevant SOC code.

The Certificate of Sponsorship

Once you hold a sponsor licence and have identified the right candidate, the next step is assigning a Certificate of Sponsorship (CoS). This is not a physical document. It is an electronic record within the Home Office's Sponsorship Management System (SMS) that links your business, the specific role, and the individual worker.

Defined vs undefined

There are two types of CoS, and using the wrong one will result in an automatic refusal:

• Defined CoS (DCoS): Required for workers applying from outside the UK (entry clearance). You request each DCoS individually through the SMS. UKVI reviews the request and, once granted (typically 1 to 2 working days), the certificate appears in your SMS account and can be assigned to the worker immediately.
• Undefined CoS (UCoS): Used for workers already in the UK who are switching or extending their visa. UCoS are drawn from an annual allocation pool. If you have available allocation, you can assign a UCoS immediately through the SMS with no per-case UKVI approval required.

The key difference is in how each type is obtained, not in how it is assigned. Both can be assigned instantly once the CoS has been granted or allocation is available.

What goes on the CoS

The CoS contains critical details about the role: the job title, SOC code, salary, working hours, start date, and work location. It also includes the worker's personal details. Any errors, particularly around SOC code selection or salary figures, can lead to refusal. The Home Office will check whether the SOC code genuinely reflects the role being offered and whether the applicant has the skills and qualifications to perform it.

CoS allocation

UCoS allocation is not automatic. When applying for a sponsor licence, you specify how many undefined certificates you expect to need in your first year. You can request zero if you do not yet have candidates in mind. UKVI then decides your allocation based on factors including your business size and compliance history.

If you need more UCoS during the year, you can request an increase through the SMS. The standard processing time for allocation requests is up to 18 weeks. A priority service is available at £350 per request, though acceptance is not guaranteed. Since March 2023, UKVI has automatically renewed annual UCoS allocations based on the number assigned in the previous 12-month period, so established sponsors may not need to request manually each year.

DCoS do not use an allocation system. Each one is requested and granted individually.

What It Costs: The Full Employer Picture

Sponsoring a Skilled Worker involves several distinct fees, spread across different stages of the process. Some are one-off, some are per-hire, and some depend on the size of your organisation.

One-off costs

Since April 2024, sponsor licences no longer expire after four years. The Home Office removed the routine renewal requirement, and licences are now valid indefinitely unless revoked or surrendered. However, sponsors remain subject to ongoing compliance duties and unannounced Home Office audits throughout the life of the licence.

Per-hire costs (employer's responsibility)

The Immigration Skills Charge adds up quickly over multi-year sponsorships. For a 5-year visa, a medium or large employer pays £6,600 per worker in ISC alone.

Visa application fees (typically the worker's responsibility)

The visa fee depends on whether the worker is applying from outside the UK (entry clearance) or from within the UK (switching or extending), and on the length of the visa. All fees below are the rates effective from 8 April 2026. Applications submitted before that date are charged at slightly lower current rates.

The Immigration Health Surcharge is £1,035 per person per year, paid upfront for the full duration of the visa. This applies to both entry clearance and in-country applications.

There is no legal requirement for employers to cover the worker's visa fee or the Immigration Health Surcharge, though many employers in competitive sectors choose to do so as part of a relocation package. However, the CoS fee and the Immigration Skills Charge must be paid by the employer. Passing these costs to the worker, whether directly or through salary deductions, is a breach of sponsor duties and can lead to licence revocation.

Example: total cost for a 3-year sponsorship (from 8 April 2026)

This example shows the combined government fees for a medium or large employer sponsoring one worker from overseas on a 3-year visa, where the employer also covers the worker's visa and health surcharge costs.

Of this, £4,485 is the employer's mandatory cost (CoS + ISC). The visa fee and IHS are the worker's responsibility by default, but many employers cover these as part of a relocation package, bringing the total employer outlay closer to £8,400 per hire. The sponsor licence fee (£1,682 for medium/large from 8 April) is additional but shared across all hires over the life of the licence.

Ongoing Employer Duties

Holding a sponsor licence is not a one-off event. It creates a continuous compliance relationship with the Home Office. These duties apply for as long as you hold the licence, regardless of how many workers you are actively sponsoring.

Reporting duties

You must report certain events to UKVI through the Sponsorship Management System, typically within 10 working days. Key reportable events include:

• The worker does not start the job
• The worker is absent from work for more than 10 consecutive working days without permission
• The worker's role, salary, or work location changes significantly
• The worker's employment ends (for any reason)
• There are changes to your organisation's circumstances (e.g. merger, acquisition, change of address, insolvency)

Record keeping

Sponsors must maintain up-to-date records for each sponsored worker, including copies of their passport, visa, right to work evidence, contact details, and attendance records. These records must be available for inspection if UKVI requests them.

Right to work checks

You must carry out right to work checks on all employees, not just sponsored workers. For sponsored workers, this means verifying their visa status before they start work and conducting follow-up checks before their visa expires. The civil penalty for employing someone without the right to work can be up to £60,000 per worker.

Compliance visits

The Home Office can carry out announced or unannounced visits to check that you are meeting your sponsor duties. These visits are more likely for businesses that are new to sponsorship, in sectors with higher non-compliance rates (such as care, hospitality, and retail), or where UKVI has identified concerns. A compliance visit typically involves reviewing your records, interviewing key personnel, and inspecting working conditions.

Common Mistakes Employers Make

Several patterns consistently lead to problems, from visa refusals to licence revocations.

Choosing the wrong SOC code

The SOC code must accurately reflect the role being performed, not just the job title. The Home Office will cross-check the code against the job description, the worker's qualifications, and the employer's track record. Choosing a higher-skilled code to meet the salary threshold, or a lower-skilled code to access a different going rate, is a common reason for refusal.

Underestimating total costs

Many employers budget only for the licence fee and discover the ISC, CoS fee, and potential worker relocation costs later in the process. Building a full cost model before beginning recruitment avoids surprises that can delay or derail a hire.

Failing to report changes

Sponsors sometimes forget to report changes, particularly when a worker moves to a different office, takes extended leave, or has their hours reduced. Unreported changes can accumulate and create serious compliance issues if discovered during a visit.

Treating sponsorship as a one-off

The licence creates ongoing duties that require designated staff, clear processes, and regular attention. Businesses that treat it as a box-ticking exercise at the application stage often struggle when the Home Office comes to check.

Timeline: From Decision to Day One

The full process from deciding to sponsor through to the worker starting typically takes 3 to 5 months. Here is a realistic timeline:

For workers already in the UK switching from another visa, the timeline is shorter because the licence application (if needed) is the main bottleneck. If UCoS allocation is available, a CoS can be assigned immediately. However, if the employer needs to request additional UCoS allocation, this can take up to 18 weeks through the standard process. In-country visa applications typically take around 8 weeks for a standard decision.

How AssessNow Can Help

The salary and eligibility rules for Skilled Worker sponsorship involve multiple variables: the specific SOC code, whether the worker qualifies as a new entrant, which salary table applies, and whether transitional provisions are relevant. Our Skilled Worker Salary Assessment checks a proposed salary against the going rate for the relevant SOC code and identifies which options apply, so you can confirm compliance before assigning the CoS.

If you are earlier in the process and need to understand whether your business is likely to qualify for a sponsor licence, our Sponsor Licence Eligibility Assessment evaluates your organisation against the Home Office's key criteria and identifies potential risks before you submit the application.
