UK Skilled Worker Visa Sponsorship: A Guide for Employers

Sponsoring a worker on the UK Skilled Worker visa has become significantly more expensive and more restrictive since July 2025. The minimum salary threshold is now £41,700, the eligible skill level has moved to RQF Level 6 (degree-equivalent), and around 180 previously eligible roles have been removed from the route.

If you’re hiring from outside the UK or considering whether a sponsor licence makes sense for your business, this guide covers the full process, the costs, and the compliance obligations that come with it.

Who Needs a Sponsor Licence

Non-UK, non-Irish nationals who do not already hold permission to work in the UK need a sponsored visa to take up employment.

That means any company hiring someone from outside the UK and Ireland, whether the candidate is based abroad or already in the country on a different visa category, must hold a valid sponsor licence before making a job offer that depends on immigration permission.

The requirement does not apply to every international hire. Citizens with settled or pre-settled status under the EU Settlement Scheme, holders of a Global Talent visa, and those on a Youth Mobility Scheme visa can work without sponsorship.

For employers, the practical implication is straightforward: check the candidate’s right to work before assuming sponsorship is needed, since some internationally mobile candidates already have permission that covers the role.

If you are using an Employer of Record to hire in the UK, the EOR holds the sponsor licence and takes on the compliance obligations. That changes the picture significantly for companies making one or two hires without a UK entity.

For a direct comparison of when an EOR makes more sense than obtaining your own licence, see the final section of this guide.

How to Apply for a Sponsor Licence

The application is submitted online through the UKVI sponsorship portal. Before applying, you need to appoint key personnel: an Authorising Officer (a senior person legally responsible for the licence), at least one Level 1 User (the person who will manage sponsorship day-to-day via the Sponsorship Management System), and optionally a Key Contact as the main point of communication with UKVI.

Supporting documents submitted alongside the application typically include your certificate of incorporation, employer’s liability insurance certificate, most recent business bank statements, and VAT registration certificate if applicable.

The Home Office publishes a full list of acceptable evidence in its Part 1 guidance, and the documents required vary depending on your business type and how long you have been trading.

Standard processing takes up to 8 weeks from the date of application. A priority service is available for an additional £750 fee, which targets a decision within 10 working days, though this is subject to a daily cap and does not apply if UKVI decides to conduct a compliance visit before granting the licence.

Compliance visits are more common for newer businesses and certain higher-risk sectors, and they can be either announced or unannounced.

Eligible Roles: Skill Levels and SOC Codes

From 22 July 2025, new Skilled Worker applications are limited to roles rated at RQF Level 6 or above, which is broadly equivalent to degree level. The job itself must be at that skill level; the worker does not need to hold a degree. Around 180 occupations previously eligible at RQF Levels 3 to 5 (A-level equivalent) have been removed from the route as a result.

Two lists provide limited exceptions for sub-degree roles. The Immigration Salary List (ISL) covers occupations the Migration Advisory Committee has identified as being in genuine shortage, where a reduced general salary threshold applies.

The Temporary Shortage List (TSL) covers around 60 RQF 3-5 occupations deemed critical to the UK’s industrial strategy, including engineering technicians, data analysts, and certain trades. The TSL carries no salary discount and the ISL is due to be phased out by December 2026.

Every sponsored role must be matched to the correct Standard Occupational Classification (SOC) code from Appendix Skilled Occupations. The SOC code determines the going rate and the salary threshold that applies. UKVI publishes the CASCOT tool for employers who need help identifying the correct code.

Choosing the wrong SOC code is one of the most common triggers for a compliance visit, so it is worth verifying the classification before assigning a Certificate of Sponsorship.

Salary Requirements

The salary a sponsored worker must be paid is whichever is higher: the general minimum threshold of £41,700 per year, or the going rate for the specific SOC code under Appendix Skilled Occupations.

For most Table 1 roles (graduate-level occupations outside health and care), a minimum hourly rate of £17.13 also applies, calculated against a maximum of 48 paid hours per week. All three tests must be satisfied simultaneously.

Several reduced thresholds apply in specific circumstances. Workers with a PhD relevant to the job can qualify at £37,500 and 90% of the going rate. Those on the new entrant route (broadly, applicants under 26 or recent graduates) can qualify at £33,400 and 70% of the going rate, for a maximum of four years.

Workers who entered the Skilled Worker route before April 2024 and are extending or changing employment face a transitional minimum of £31,300 rather than £41,700. From 9 April 2025, any repayments deducted from a worker’s salary, including clawback arrangements, must be factored into the gross pay calculation when checking threshold compliance.

Only guaranteed basic gross pay counts toward the salary requirement. Allowances, including London weighting and guaranteed bonuses, do not count unless they are permanent, paid for the full duration of the visa, and available to settled workers on the same terms.

The Certificate of Sponsorship

A Certificate of Sponsorship (CoS) is an electronic record, not a physical document, assigned to a specific worker for a specific role via the Sponsorship Management System. There are two types. A Defined CoS is used for workers applying from outside the UK on the Skilled Worker route; each one must be applied for individually.

An Undefined CoS is drawn from an annual allocation and is used for workers already in the UK switching visa categories or extending permission.

Before assigning a CoS, the sponsor must confirm the role is eligible, the salary meets the applicable threshold, and the SOC code is correct. The CoS must be assigned no more than 3 months before the worker’s intended start date, and the worker must submit their visa application within 3 months of the CoS being assigned.

If any detail on the CoS is wrong, salary, job title, start date, SOC code, it can result in a visa refusal and the loss of the £525 CoS fee with no guarantee of a replacement.

Sponsors cannot assign a Defined CoS without first requesting approval from UKVI for each one. This is a separate process from the annual Undefined CoS allocation and adds time to the hiring process for overseas candidates. Build this into your recruitment timeline before making an offer.

What Sponsorship Actually Costs

The headline sponsor licence fee is £611 for small or charitable organisations and £1,682 for medium or large organisations, based on UKVI’s size classification criteria. Each CoS assigned under the Skilled Worker route costs £525, payable per worker.

On top of that, the Immigration Skills Charge (ISC) applies to most Skilled Worker hires: £480 per year for small sponsors and £1,320 per year for large sponsors, following a 32% increase that took effect on 16 December 2025. The ISC is paid upfront in full when the CoS is assigned, covering the entire visa period.

Since 31 December 2024, sponsors are legally prohibited from recovering the licence fee, CoS fee, or ISC from sponsored workers. Attempting to do so is a ground for licence revocation.

The only costs that can still be recovered through a properly structured clawback agreement are the worker’s own visa application fee and Immigration Health Surcharge, which are paid by the worker directly.

For a single Skilled Worker on a three-year visa, the employer’s minimum outlay before the worker’s first day looks like this: sponsor licence fee (one-off, amortised across all hires), £525 CoS fee, and ISC of £1,440 for a small sponsor or £3,960 for a large sponsor.

Add legal support if used, and the total cost of a first sponsored hire on a three-year visa regularly reaches £8,000 to £12,000 for a large organisation.

Ongoing Sponsor Duties

Holding a sponsor licence is an ongoing regulatory obligation, not a one-time approval. The Home Office Part 3 compliance guidance sets out three core duties: keeping accurate records for every sponsored worker, monitoring their attendance and immigration status, and reporting specified changes to UKVI via the Sponsorship Management System within 10 working days.

Changes that must be reported include a worker’s failure to show up on their start date, unexplained absences, resignation, dismissal, or a material change to their role or salary.

From April 2026, UKVI cross-references HMRC payroll data directly against information held on the SMS. This means discrepancies between the salary stated on the CoS and what the worker is actually paid can be identified without a compliance visit.

Sponsored workers must receive at least their required salary in every individual pay period; making up a shortfall in one month through a higher payment in the next is no longer acceptable. Employers using variable pay structures need to review their payroll processes against this requirement before it creates a compliance issue.

Right-to-work checks are now conducted via eVisa rather than physical documents, following the full transition away from Biometric Residence Permits. Sponsors must verify digital immigration status before employment begins and retain evidence of having done so.

From March 2026, updated Appendix D guidance also requires sponsors to document that they have informed sponsored workers of their employment rights under UK law, including changes introduced by the Employment Rights Act 2025. This applies to the entire sponsored workforce, not only new starters.

Statutory leave entitlements for sponsored workers are identical to those for any UK employee, including the right to maternity and paternity leave. For a full breakdown of those obligations, see our UK maternity and paternity leave guide.

Recent Rule Changes to Know Before You Hire

The Skilled Worker route has changed more in the past 18 months than in the previous five years combined.

The most significant shift is the move to RQF Level 6 as the minimum skill threshold from 22 July 2025, which removed around 180 occupations from the route and effectively ended the use of the Skilled Worker visa for most mid-skilled roles.

The general salary floor moved from £38,700 to £41,700 on the same date, based on updated Annual Survey of Hours and Earnings data.

From 8 January 2026, first-time Skilled Worker applicants must demonstrate English language proficiency at B2 level rather than the previous B1 standard. This raises the bar for candidate eligibility and can extend pre-application timelines if candidates need to resit tests.

The ban on recovering sponsorship costs from workers took effect on 31 December 2024 for the Skilled Worker route, making the full cost stack an employer liability with no contractual workaround.

From April 2026, automatic HMRC and SMS data matching has replaced reliance on self-reporting for salary compliance. And the March 2026 update to sponsor guidance lowered the threshold for enforcement action from proven non-compliance to reasonable suspicion, a meaningful shift in how UKVI approaches inspections.

EOR vs Sponsor Licence for UK Hiring

For companies hiring one to three people in the UK without an existing entity, an EOR is almost always the faster and lower-risk route.

The EOR holds the sponsor licence, absorbs the compliance obligations, and can typically onboard a Skilled Worker candidate within one to three weeks once the visa is in place. You avoid the 8-week licence application window, the upfront ISC payment, and the ongoing SMS reporting duties.

Our UK EOR rankings cover the providers best equipped to handle Skilled Worker sponsorship alongside PAYE and IR35 compliance.

The calculus shifts once you are hiring at volume or planning a long-term UK presence. At five or more sponsored hires per year, the per-hire cost of the ISC and CoS fees is the same whether you hold the licence or route through an EOR, but the EOR’s monthly fee adds a recurring cost that a direct licence does not.

Companies building a UK team of 10 or more, or those needing to sponsor workers in roles where the EOR’s own licence coverage is limited, are generally better served by obtaining their own licence.

The one scenario where neither option is straightforward is contractor conversion. If your UK contractors are at risk of being reclassified as employees under IR35, that reclassification does not automatically trigger a visa requirement, but if the contractor is a non-UK national whose right to work depends on their current immigration permission, converting them to employment may require a sponsored visa under a new or existing licence. Get legal advice before making that change.
