The employer carries the compliance risk — not the candidate. UK work permit sponsorship is employer-led. Before any candidate can apply, you must hold a valid Sponsor Licence from the Home Office. Getting this wrong isn’t just a delay — it’s a legal exposure.
Costs add up faster than most businesses expect. Between the Sponsor Licence fee, Certificate of Sponsorship, Immigration Skills Charge, and visa application costs, a single 3-year hire can easily run to £5,000–£8,000+ in government fees alone — before any professional support.
Sponsorship is an ongoing HR function, not a one-off task. Securing the visa is just the start. Sponsors have continuous duties: right to work checks, reporting role or salary changes, tracking visa expiry dates, and cooperating with Home Office inspections. Most compliance failures happen months after hire, not at the application stage.
Finding the right person for a role doesn’t stop at borders. For scaleups and growing businesses, some of the best candidates are already working internationally — and hiring them into UK roles means navigating the UK’s post-Brexit work permit system from the employer’s side.
Most guides on UK work permits focus on what the employee needs to do. This one focuses on what you, as the hiring organisation, are responsible for — because it’s companies, not candidates, that carry the compliance risk.
This guide covers the main visa routes relevant to employer-sponsored hiring, the steps you need to take to become a licensed sponsor, what the process realistically involves, and where professional support can prevent costly delays.
In the UK, work authorisation under the points-based immigration system is employer-led. That means before a candidate can apply for a visa, you as the employer must hold a valid Sponsor Licence issued by the Home Office.
Without it, you cannot legally employ someone who requires immigration permission to work in the UK — regardless of how well-suited they are to the role. This is the step most businesses underestimate.
The UK uses a points-based immigration system. Below are the routes most relevant to employers hiring international talent into skilled roles.
| Visa Route | Best for | Min. Salary (2026) | Sponsor Needed? | Typical Timeline |
|---|---|---|---|---|
| Skilled Worker Visa | Most skilled/professional hires | £41,700 (or going rate, if higher) | Yes | 3–8 weeks (employee) |
| Health & Care Worker Visa | Healthcare professionals, NHS supply chain | As per NHS pay scales | Yes | 3–8 weeks (employee) |
| Scale-up Visa | Fast-growth companies sponsoring senior talent | £39,100+ | Yes (year 1 only) | 2–6 weeks (employee) |
| Global Talent Visa | Exceptional talent in tech, science, arts | No minimum | No (endorsement body instead) | 3–8 weeks |
| Graduate Visa | Candidates who studied in the UK | No minimum | No | N/A — self-led |
If you intend to hire on a Skilled Worker Visa, the first step is obtaining a Sponsor Licence from the Home Office. This is a one-time application that, once granted, allows you to issue Certificates of Sponsorship (CoS) to individual candidates.
The fee charged for the UK Sponsor License depends on the size of the company and a type of the license.
| Type of Licence | Fee for small or charitable sponsors | Fee for medium or large sponsors |
|---|---|---|
| Worker | £611 | £1,682 |
| Temporary Worker | £611 | £611 |
A common mistake at this stage is assuming the licence application is straightforward. The Home Office conducts pre-licence visits on a proportion of applicants, and licence refusals are difficult and slow to appeal. Getting the application right first time matters.
“In our experience, most Sponsor Licence applications are delayed not because of missing documents, but because the Home Office isn’t convinced the company has the infrastructure to properly manage sponsorship responsibilities.”
— Zaka Ullah, UK Operations Lead at ThisWorks
Once licenced, you don’t issue a physical document to your candidate. Instead, you assign a Certificate of Sponsorship — a digital reference number — through the Sponsorship Management System (SMS). The candidate then uses this reference in their visa application.
There are two types of CoS relevant for Skilled Worker applications:
Once you have assigned the CoS, your candidate can submit their Skilled Worker Visa application via the UK Visas and Immigration (UKVI) online portal. This is largely the candidate’s process to manage — but the quality of information in the CoS you have issued directly affects the outcome.
Processing times vary. Standard processing for most Skilled Worker applications from outside the UK is around 3 weeks, with a priority service available for an additional fee. Employers should factor this into their start date planning.
Obtaining the licence and securing the visa is not the end of your obligations. UK sponsors are subject to ongoing duties enforced by the Home Office — and non-compliance can result in licence suspension, downgrading, or revocation.
“Most compliance issues don’t happen at the application stage — they happen 6–12 months later when reporting duties are missed or internal ownership becomes unclear. Sponsorship is an ongoing HR function, not a one-off process.”

| Sponsor Licence Application | Employer | £611 (small) / £1,682 (medium/large) |
| Certificate of Sponsorship | Employer | £525 per CoS |
| Immigration Skills Charge | Employer | £480/yr (small) or £1,320/yr (large) — per worker |
| Skilled Worker Visa Application | Candidate (or employer) | £819–£1,865 per applicant depending on salary & duration |
| Immigration Health Surcharge | Candidate (or employer) | £1,035 per year of visa |
| Priority Processing (optional) | Candidate | £500+ |

For a single hire on a 3-year Skilled Worker Visa, an employer can easily spend £5,000–£8,000+ in government fees alone before counting professional support costs. That’s before factoring in internal HR time, potential delays, and compliance overhead.
Based on the experience of employers across the UK, these are the points of failure most likely to delay or derail a sponsored hire:
“One of the most common situations we see is tech scaleups hiring their first non-EEA employee after years of EU-only recruitment. It often turns into a time pressure issue — they’ve made an offer, but only then realise a Sponsor Licence is required and not yet in place.”
— ThisWorks Team
Not every business is in a position to hold its own Sponsor Licence — and not every hire requires it. An Employer of Record (EOR) model offers an alternative route for companies that:
Under an EOR arrangement, the provider becomes the legal employer of your worker in the UK — handling payroll, employment contracts, tax compliance, and, where applicable, work permit sponsorship through their own licence. You retain day-to-day management of the employee and the commercial relationship.
“We recently worked with a Dutch software company hiring their first UK-based engineer. They used our EOR setup to get the employee started within three weeks, while we prepared their Sponsor Licence at the same time. This meant there was no hiring delay, and once the licence was approved, they moved straight into direct sponsorship for their next hire.”

No — for Skilled Worker Visa hires, a valid Sponsor Licence is mandatory before you can assign a CoS. The only alternatives are hiring through an EOR who holds their own licence, or hiring candidates who already have the right to work in the UK independently (e.g. British citizens, settled status holders, Graduate Visa holders).
Standard processing is currently up to 8 weeks. A priority service is available for an additional fee, reducing this to around 10 working days. Factor this into your hiring timeline — apply before you need it, not after you’ve made an offer.
Yes — intra-company transfers previously had a dedicated visa route, but this was closed in 2024. International employees now use the Skilled Worker Visa route, provided the role meets the salary and skill requirements.
Yes — a Skilled Worker Visa is tied to the sponsoring employer. If the employee changes jobs, the new employer must also be a licensed sponsor and assign a new CoS. You are also required to inform the Home Office if a sponsored worker leaves your employment.
Non-compliance can result in your Sponsor Licence being downgraded to ‘B’ rating, suspended, or revoked. If your licence is revoked, sponsored workers typically have 60 days to find a new sponsor or leave the UK. The reputational and operational risk is significant — particularly for businesses with multiple sponsored employees.
Hiring internationally doesn’t have to mean setting up a local entity, building payroll infrastructure or navigating complex employment legislation on your own. Whether you are hiring your first remote employee or expanding an international team, our specialists can support a smooth, compliant onboarding process in just a few days.
