UK Visa Sponsorship for Employers: A Practical Guide to Licences and Responsibilities

If your business wants to hire skilled talent from outside the UK, you can’t simply extend a job offer and leave the rest to the applicant. You need a sponsorship licence for companies from the Home Office before you can sponsor anyone. This guide explains the different licence types, how the application process works, and what ongoing duties come with holding one.
Why Employers Need a Sponsor Licence
Almost every route that allows someone to come to the UK for skilled or long-term employment, including the skilled worker visa, requires the worker to hold a Certificate of Sponsorship from an approved employer. Without a licence, you simply cannot issue one, no matter how strong the candidate is. This makes the sponsor licence the essential first step for any UK business planning to recruit internationally, whether that’s a one-off senior hire or an ongoing pipeline of overseas talent.
The Two Main Licence Categories
Sponsor licences fall broadly into two groups, and you can apply for one or both depending on your hiring needs.
Worker Licences
A Worker licence covers skilled or long-term employment and splits further into:
- Skilled Worker — for roles that meet the job suitability and salary requirements
- Senior or Specialist Worker (Global Business Mobility) — for multinational companies transferring established employees into the UK
- Minister of Religion — for religious organisations bringing in workers
- International Sportsperson — for elite athletes and coaches based in the UK
Temporary Worker Licences
A Temporary Worker licence covers shorter, more specific arrangements, including:
- Scale-up Worker — for fast-growing UK businesses
- Creative Worker — for entertainers and artists, up to two years
- Charity Worker — for unpaid roles at a registered charity, up to one year
- Religious Worker — up to two years, for religious orders or organisations
- Government Authorised Exchange — for research, training, or short-term knowledge exchange
- International Agreement — for roles covered by international law, such as overseas government employees
- Graduate Trainee, Service Supplier, UK Expansion Worker, and Secondment Worker (Global Business Mobility) — for various intra-group transfers and contracted service provision
- Seasonal Worker — for horticulture and poultry roles during specific windows of the year
Licence Categories Compared
| Licence Type | Typical Duration | Best Suited To |
| Skilled Worker | Up to 5 years, extendable | Long-term skilled hires across most sectors |
| Senior/Specialist Worker (GBM) | Varies by transfer arrangement | Multinationals moving established staff to the UK |
| Scale-up Worker | Sponsorship duties end after 6 months | Fast-growing UK businesses |
| Charity Worker | Up to 1 year | Unpaid roles at registered charities |
| Seasonal Worker | Up to 6 months (poultry: fixed autumn window) | Horticulture and poultry sectors |
Notably, once a scale-up worker has held their permission for six months, your sponsorship responsibilities for that individual end, and they can continue working for you, or even change jobs without a new sponsor, for the remainder of their visa. This is quite different from a standard skilled worker visa holder, who generally needs a sponsor to update their CoS if they change roles.
Job Suitability and Salary Requirements
Not every vacancy qualifies for sponsorship. The role must sit on the list of eligible occupations and meet a minimum salary threshold that varies by job type. Employers should check job suitability carefully before offering sponsorship, since assigning a Certificate of Sponsorship to an ineligible role can jeopardise your licence and, in serious cases, lead to its suspension or revocation.
Sponsorship Management Roles
Once licensed, you’ll need to nominate people within your organisation to manage sponsorship duties, typically an Authorising Officer, a Key Contact, and one or more Level 1 Users who handle day-to-day certificate assignments through the sponsorship management system. Choosing the right people for these roles matters, since they carry legal responsibility for keeping records accurate and reporting changes on time.
Applying for Your Licence
The application is submitted online and requires evidence of your organisation’s legitimacy, HR systems, and right-to-work compliance processes. The Home Office may also carry out a compliance visit before or after granting the licence, so it pays to have your record-keeping in order from day one, including HR files, right-to-work checks, and a clear organisational structure that maps to your nominated sponsorship roles.
Your Licence Rating
Licences are given an A or B rating. An A-rating allows you to assign Certificates of Sponsorship immediately; a B-rating means the Home Office has identified issues that need addressing through an action plan before you regain full sponsorship capability. Falling from an A to a B rating, or having your licence revoked entirely, can happen if compliance duties aren’t met.
Rating and Compliance Overview
| Rating | What It Means | Employer Action |
| A-rating | Full sponsorship capability, no outstanding issues | Maintain records and report duties on schedule |
| B-rating | Compliance concerns identified | Follow the action plan to restore A-rating status |
| Suspended | Sponsorship capability paused pending review | Respond promptly to Home Office correspondence |
| Revoked | Licence withdrawn | Existing sponsored workers’ visas may be curtailed |
ATAS Checks
For certain sensitive subject areas, sponsored workers may need an Academic Technology Approval Scheme (ATAS) certificate before they can start their role. This mostly affects research-related and technical positions, so it’s worth checking early in the recruitment process rather than after an offer has been made, since ATAS processing can take several weeks and delay a start date.
The Immigration Skills Charge
Sponsors are usually required to pay an Immigration Skills Charge for each worker they sponsor on a relevant route. This is separate from the application fee and is charged per year of the certificate’s validity, so it’s worth factoring into your total hiring cost before you commit to a role, particularly for longer sponsorship periods where the charge accumulates significantly.
Your Ongoing Responsibilities as a Sponsor
- Reporting changes in a sponsored worker’s circumstances, such as absences, role changes, or resignation
- Keeping accurate HR and right-to-work records
- Cooperating fully with compliance checks and site visits
- Ensuring roles and salaries continue to meet the eligibility thresholds throughout employment
Failing to meet these responsibilities is one of the most common reasons licences get downgraded or revoked, and the consequences extend beyond the business itself; sponsored employees can see their own visas curtailed if their employer’s licence is suspended.
What Happens When a Sponsored Employee’s Visa Nears Expiry
As your sponsored employees approach the end of their permission to stay, it’s worth planning renewals well ahead of time. Our visa extension support service helps employees keep their status current, and where relevant, some employees may later look at options such as post-study work routes if their circumstances change, or a permitted paid engagement visa for short, specific work-related visits that fall outside standard sponsorship.
Frequently Asked Questions
How long does it take to get a sponsor licence?
Timelines vary depending on Home Office workload and whether a compliance visit is required, so employers planning to hire internationally should apply well before they need to issue a Certificate of Sponsorship.
Can a small business apply for a sponsor licence?
Yes, there’s no minimum size requirement, but the business must demonstrate genuine trading activity and the HR systems needed to meet sponsorship duties.
What happens to sponsored employees if our licence is revoked?
Sponsored workers are typically given a short period to find a new sponsor or otherwise regularise their status, so acting quickly and communicating clearly with affected staff is essential.
Building a Sustainable Sponsorship Function
Businesses that sponsor workers successfully over the long term tend to treat sponsorship as an ongoing HR function rather than a one-off administrative task tied to a single hire. That means building internal checklists for reporting duties, calendar reminders for key dates such as visa expiries and compliance renewals, and clear internal ownership so that responsibilities don’t fall through the cracks when a nominated Level 1 User leaves the business or changes role.
It’s also worth reviewing your sponsorship processes periodically, particularly if your hiring volume grows quickly or if you expand into new licence categories. A compliance framework that worked comfortably for five sponsored workers may need to be strengthened considerably once that number reaches fifty, and the Home Office expects sponsors to scale their internal controls in step with their sponsorship activity.
Final Thoughts
Sponsoring overseas workers gives UK employers access to a much wider talent pool, but it comes with real administrative weight, from choosing the right licence category to maintaining an A-rating year after year. Getting the structure right from the outset, and keeping on top of your ongoing duties, is what separates a smooth sponsorship operation from one that risks losing its licence.
