The Complete Guide to UK Sponsor Licences: Everything Businesses Need to Know

What is a UK Sponsor Licence?

A UK sponsor licence is a permission granted by the Home Office (UK Visas and Immigration, or UKVI) that allows a UK-based employer to hire workers from outside the UK. It acts as a guarantee from the employer that they will take responsibility for the foreign workers they employ.

When you hold a sponsor licence, you can issue a Certificate of Sponsorship (CoS) to a prospective employee. The employee then uses this certificate to apply for their UK work visa.

Who Needs a Sponsor Licence?

You need a sponsor licence to employ anyone who does not already have the right to work in the UK. This includes citizens of the EU, Iceland, Liechtenstein, Norway, and Switzerland who arrived in the UK after 31 December 2020.

You do not need a sponsor licence to employ:

• British or Irish citizens
• Individuals with settled or pre-settled status under the EU Settlement Scheme
• Individuals with Indefinite Leave to Remain (ILR) in the UK
• Individuals holding a visa that allows them to work without sponsorship (such as a Graduate visa, Global Talent visa, or certain dependent visas)

Types of UK Sponsor Licences

The UK immigration system divides sponsor licences into two main categories: Worker licences and Temporary Worker licences. You can apply for a licence covering one or both types, depending on your business needs.

Worker Licence

A Worker licence allows you to sponsor people in skilled employment. This can be for short-term, long-term, or permanent roles. The main routes under this licence include:

• Skilled Worker: The most common route, used to sponsor individuals for specific skilled jobs that meet minimum salary and skill thresholds
• Global Business Mobility (Senior or Specialist Worker): For multinational companies transferring established employees to their UK branch.
• Minister of Religion: For individuals coming to work for a religious organisation.
• International Sportsperson: For elite sportspeople and coaches based in the UK.

Temporary Worker Licence

A Temporary Worker licence allows you to sponsor individuals on a temporary basis, including for volunteering, job-shadowing, or specific short-term contracts. Routes include:

• Scale-up Worker: For fast-growing UK businesses hiring highly skilled individuals.
• Creative Worker: For entertainers or artists working in the creative industry for up to two years.
• Charity Worker: For unpaid workers at a charity for up to one year.
• Seasonal Worker: For individuals working in horticulture or poultry production for up to six months.

Eligibility Requirements for Businesses

To successfully apply for a sponsor licence, your business must prove it is eligible and suitable. The Home Office assesses applications based on several core criteria. Understanding these requirements before you apply is essential. A refused application not only wastes the application fee, but also triggers a cooling-off period before you can reapply.

General Eligibility

You must demonstrate that your business is a genuine organisation operating legally in the UK. You cannot hold unspent criminal convictions for immigration offences or certain other crimes, such as fraud or money laundering. Furthermore, you cannot have had a sponsor licence revoked within the last 12 months .

The Home Office will also check whether any of your key personnel have a history of non-compliance with immigration law. If a director or senior employee has previously been involved in a business whose licence was revoked, that history will be scrutinised.

HR and Monitoring Systems

This is where many applications fail, particularly for smaller businesses. UKVI requires you to have robust, documented HR systems in place before you apply not after. These systems must allow you to:

• Carry out and record right to work checks for all employees, not just sponsored workers
• Store copies of passports, visas, and biometric residence permits
• Track attendance and identify unexplained absences
• Maintain up-to-date contact details for all sponsored workers
• Monitor the expiry dates of sponsored workers' visas

If UKVI conducts a pre-licence compliance visit and finds that your systems are inadequate or poorly documented, your application will be refused. The Home Office does not require you to use a specific software system, but your processes must be consistent, auditable, and capable of producing records on request.

Genuine Vacancies

You must prove that you have genuine employment needs that meet the skill and salary requirements of the relevant visa route. You cannot create a role simply to facilitate someone's entry into the UK.

For the Skilled Worker route, the role must be at or above RQF Level 3 (equivalent to A-level) and meet the relevant salary threshold. The general minimum salary threshold for Skilled Worker sponsorship is £41,700 per year, though lower thresholds apply for shortage occupation roles and certain sectors such as health and education.

Inconsistencies between the job description, the salary offered, and the business's trading history are common grounds for refusal.

Business Viability

Your business must be trading and financially viable. The Home Office will check Companies House records, HMRC registration, and other public data. New businesses without an established trading history face additional scrutiny and may be asked to provide more supporting evidence, such as contracts with clients, bank statements, or business plans.

For a detailed breakdown of these criteria, see: UK Sponsor Licence Eligibility Requirements for Businesses

Key Personnel Roles

When applying for a sponsor licence, you must nominate specific individuals within your organisation to manage the licence and use the Sponsorship Management System (SMS). These are known as 'Key Personnel'.

The required roles are:

• Authorising Officer: A senior, competent person responsible for the actions of all staff and representatives who use the SMS. They hold ultimate responsibility for compliance.
• Key Contact: The main point of contact between your business and UKVI.
• Level 1 User: The person responsible for the day-to-day management of the licence using the SMS. They can assign Certificates of Sponsorship and report changes.

At least one Level 1 User must be an employee, partner, or director of the organisation, and they must usually be a 'settled worker' in the UK .

The True Cost of a Sponsor Licence

Budgeting for a sponsor licence involves considerably more than the initial application fee. Businesses that fail to account for the full cost of sponsorship often find themselves underprepared, particularly when sponsoring multiple workers or planning for long-term recruitment.

Application Fees

The application fee depends on the size and type of your organisation.

You are generally considered a small sponsor if at least two of the following apply: your annual turnover is £15 million or less; your total assets are worth £7.5 million or less; or you have 50 or fewer employees .

Certificate of Sponsorship Fees

Each time you sponsor a worker, you must assign them a Certificate of Sponsorship and pay a fee per certificate. The current fees are

• Worker routes (e.g., Skilled Worker): £239 per certificate
• Temporary Worker routes: £25 per certificate

These fees are non-refundable, even if the worker's visa application is subsequently refused.

Immigration Skills Charge

The Immigration Skills Charge (ISC) is a levy payable by employers when assigning a Certificate of Sponsorship for most Worker routes, including the Skilled Worker route. It is designed to fund skills training for the UK resident workforce.

The charge is calculated based on the length of the worker's visa and your organisation's size:

For a worker on a three-year Skilled Worker visa, a medium or large employer would pay £3,000 in Immigration Skills Charge alone, in addition to the CoS fee and the original licence application fee.

Certain roles are exempt from the ISC, including PhD-level occupations and workers on some Global Business Mobility routes. The charge is also not payable for Temporary Worker routes.

Other Costs to Factor In

Beyond the direct Home Office fees, businesses should also budget for:

• Legal or advisory fees if using an immigration adviser or solicitor to manage the application
• Priority service fee of £500 if you need a faster decision on your licence application
• Compliance costs such as HR software, staff training, or external audits
• Visa application fees paid by the worker (though some employers choose to cover these as part of their relocation package)

The Application Process

Applying for a sponsor licence requires careful preparation. Rushing the process often leads to mistakes and refusals, and a refused application cannot be appealed — only reviewed in limited circumstances.

Step 1: Assess Your Eligibility

Before you begin the application, confirm that your business meets the eligibility criteria. Check that your HR systems are in place, that your key personnel meet the requirements, and that the roles you intend to sponsor are genuine and meet the relevant skill and salary thresholds.

Step 2: Choose the Correct Licence Type

Decide whether you need a Worker licence, a Temporary Worker licence, or both. If you are unsure which visa route applies to the worker you want to hire, take advice before applying. Applying for the wrong licence type wastes both time and money.

Step 3: Appoint Key Personnel

Nominate your Authorising Officer, Key Contact, and at least one Level 1 User. Ensure each person understands their responsibilities before you submit the application, as UKVI may contact them directly during the assessment process.

Step 4: Gather Supporting Documents

UKVI publishes a list of mandatory and optional supporting documents in Appendix A of the sponsor guidance. The documents you need depend on your organisation type and the licence you are applying for. Common requirements include:

• Evidence of registration with HMRC (such as a VAT registration certificate or employer's PAYE reference)
• Evidence that your business is operating and trading (such as a bank statement or signed contract with a client)
• Evidence of your business premises (such as a lease agreement or utility bill)
• Evidence of the Authorising Officer's identity and seniority within the business

Documents not in English or Welsh must be accompanied by a certified translation.

Step 5: Submit the Online Application

Complete the online application form via the UKVI sponsorship management system and pay the relevant fee. At the end of the application, you will receive a submission sheet. You must send this sheet, along with your supporting documents, to the Home Office within five working days.

Step 6: Await a Decision

Standard processing takes approximately eight weeks. During this time, UKVI may contact you for additional information or arrange a compliance visit to your premises. If you need a faster decision, you can pay £750 for the priority service, which aims to deliver a decision within ten working days.

What Happens After Approval

If your application is successful, you will receive a licence number and be listed on the public register of licensed sponsors. You can then begin assigning Certificates of Sponsorship to workers and supporting their visa applications.

Certificates of Sponsorship: Defined vs Undefined

Once you hold a sponsor licence, you can issue a Certificate of Sponsorship (CoS) to each worker you intend to sponsor. There are two types, and understanding the difference is important for planning your recruitment timeline.

Defined Certificate of Sponsorship

A defined CoS is required when a worker is applying for their visa from outside the UK. You must request a defined CoS from UKVI before assigning it to the worker. UKVI will assess the request and, if approved, issue the certificate. The worker then uses it to make their visa application from abroad.

Defined CoS requests are assessed individually and are not issued automatically. You should allow additional time in your recruitment process for this step.

Undefined Certificate of Sponsorship

An undefined CoS is used when a worker is already in the UK and applying to switch to a sponsored route (for example, switching from a Graduate visa to a Skilled Worker visa). It is also used for most Temporary Worker routes.

Unlike defined CoS, undefined CoS are allocated to you in an annual batch. You can assign them to workers without seeking individual approval from UKVI, provided the role meets the relevant requirements. If you need more undefined CoS than your annual allocation allows, you can request additional certificates through the Sponsorship Management System.

Sponsor Licence Ratings

If your application is successful, you will be awarded an 'A-rating'. This allows you to start assigning Certificates of Sponsorship to workers.

Your business will be listed on the public register of sponsors. You must maintain your compliance to keep your A-rating.

If UKVI finds that you are failing in your sponsor duties, they may downgrade your licence to a 'B-rating'. A B-rating means you cannot issue new Certificates of Sponsorship until you have completed a time-limited action plan to improve your processes. If you fail to improve, your licence may be revoked.

Your Responsibilities as a Sponsor

Holding a sponsor licence is a privilege, not a right. The Home Office places significant trust in sponsors to act as a first line of immigration control. Businesses that treat compliance as an afterthought — rather than an ongoing operational commitment — are the ones that face enforcement action.

Record Keeping

You must maintain accurate, up-to-date records for every sponsored worker throughout their employment. This includes:

• A copy of their current passport or travel document
• A copy of their visa or biometric residence permit (BRP)
• Evidence of their right to work check, carried out before they started work
• Their current UK contact address and personal contact details
• Their National Insurance number
• A record of their absences from work, including any unpaid leave

These records must be kept for the duration of the worker's employment and for at least two years after they leave. UKVI can request access to these records at any time, including during an unannounced compliance visit.

Reporting Duties

You are required to report certain events to UKVI using the Sponsorship Management System (SMS). Most reports must be made within 10 working days of the event. Reportable events include:

• A sponsored worker failing to turn up for their first day of work
• A sponsored worker's employment ending earlier than stated on their CoS
• A sponsored worker being absent from work for more than 10 consecutive working days without authorisation
• A significant change in the worker's role, salary, or working location
• Any significant changes to your business, such as a change of ownership, merger, or insolvency proceedings

Failure to report these events is one of the most common reasons for compliance action. UKVI treats unreported changes as evidence that a business is not managing its sponsorship duties properly.

Compliance with UK Employment Law

As a sponsor, you must comply with all relevant UK employment legislation. This includes paying sponsored workers at least the National Minimum Wage, providing written terms of employment, and complying with working time regulations. UKVI works alongside HMRC and the Employment Agency Standards Inspectorate, and non-compliance in one area can trigger scrutiny in another.

Preparing for Compliance Visits

UKVI conducts compliance visits to verify that sponsors are meeting their duties. These visits can be pre-announced or unannounced, and they can happen at any point during the life of your licence — not just after a complaint or concern has been raised.

During a visit, a UKVI officer will typically review your HR records, speak with key personnel, and assess whether your monitoring systems are functioning as described in your application. Businesses that are well-prepared for these visits — with organised, accessible records and trained staff — are far less likely to face enforcement action.

Consequences of Non-Compliance

The Home Office takes sponsor licence compliance seriously, and the consequences of falling short range from administrative penalties to criminal prosecution. Understanding the enforcement framework is essential for any business that holds or is considering applying for a licence.

Licence Suspension

If UKVI believes you are breaching your sponsor duties or pose a threat to immigration control, it can suspend your licence immediately. During a suspension, you cannot assign new Certificates of Sponsorship, though workers you have already sponsored can usually continue working. You will have 20 working days to respond to the suspension notice. UKVI will then either lift the suspension, downgrade your licence to a B-rating, or revoke it entirely.

Licence Downgrade

A downgrade from an A-rating to a B-rating means you cannot issue new Certificates of Sponsorship until you have completed a mandatory, paid action plan set by UKVI. You typically have three months to complete the plan. A second B-rating within a rolling four-year period is treated as evidence of systemic failure and makes revocation highly likely.

Licence Revocation

Revocation is the most serious outcome. If your licence is revoked, you lose the right to sponsor workers immediately. Any workers you currently sponsor will have their permission to stay in the UK curtailed, and they will need to find alternative employment or leave the country. You will generally be barred from reapplying for a sponsor licence for at least 12 months.

Civil Penalties for Illegal Working

Separate from the licence enforcement regime, employers who are found to have employed illegal workers face significant civil penalties. As of 2024, the maximum fines are :

• £45,000 per illegal worker for a first offence
• £60,000 per illegal worker for each subsequent offence

These penalties apply regardless of whether you hold a sponsor licence. A business can face civil penalties for employing an illegal worker even if the worker was not sponsored through the licence system. For example, if a right to work check was not carried out correctly.

Serious or repeated breaches can also result in criminal prosecution of company directors and senior managers, with potential custodial sentences.
