UK Sponsor Licence Guide for Employers

A sponsor licence is the legal requirement for hiring workers from outside the UK and Ireland on most sponsored visa routes. Without one, you cannot lawfully offer employment to overseas nationals on the Skilled Worker visa, Health and Care Worker visa, or other sponsored routes. This guide covers the full picture — from eligibility and costs to compliance duties and what to do if things go wrong.

1. What Is a Sponsor Licence?

The licence operates through an online system called the Sponsor Management System (SMS). Once approved, your organisation is assigned a licence rating and you can begin assigning Certificates of Sponsorship (CoS) to individual workers you wish to hire.

There are two types of sponsor licence: a Worker licence and a Temporary Worker licence. Most employers looking to hire for skilled, permanent-type roles will need the Worker licence, specifically to sponsor workers on the Skilled Worker route.

What a sponsor licence does not cover

A sponsor licence does not give you permission to hire anyone from anywhere in the world. It applies only to specific immigration routes. Workers from the EU, EEA and Switzerland who arrived in the UK before 31 December 2020 may already have status under the EU Settlement Scheme and do not require sponsorship. Hiring workers with existing right to work in the UK requires no licence at all.

2. Who Needs a Sponsor Licence?

Any UK employer that wants to hire a worker from outside the UK and Ireland who requires a work visa needs a sponsor licence — if that visa route requires sponsorship. The main routes are:

• Skilled Worker visa — the most commonly used route, covering a wide range of occupations
• Health and Care Worker visa — a sub-route of Skilled Worker for NHS and care sector employers
• Senior or Specialist Worker visa — for intracompany transfers
• Graduate Trainee visa — for graduate placements within multinational companies
• Temporary Worker routes — including Charity, Creative and Sporting, Government Authorised Exchange, and others
• Scale-up Worker visa — for high-growth businesses, though this route has specific eligibility criteria

Sectors with high licence uptake

Certain sectors account for a disproportionate share of sponsor licence applications: healthcare, social care, hospitality, engineering, technology, and higher education. This reflects both skills shortages in these areas and higher rates of international recruitment.

Start-ups and newly incorporated companies

There is no minimum trading period required before applying, but the Home Office will scrutinise whether the business is genuine and financially viable. Start-ups applying for a licence should expect closer examination of their business plan, contracts, and funding position. A company registered yesterday with no revenue and no contracts is unlikely to be approved.

3. Sponsor Licence Requirements

Before applying, you need to satisfy a series of eligibility requirements. These fall into two categories: business requirements and HR system requirements.

Business requirements

Your organisation must:

• Be a genuine business operating lawfully in the UK
• Have a UK trading address that the Home Office can visit
• Not have had a sponsor licence refused or revoked in the last 12 months (in most circumstances)
• Not have any directors or senior personnel with unspent convictions for relevant offences
• Be able to demonstrate that you have genuine vacancies that meet the visa route's requirements

HR system requirements

The Home Office expects sponsors to have systems capable of monitoring and tracking sponsored workers. Specifically, you must be able to:

• Keep copies of relevant documents for each sponsored worker
• Track and report changes to a worker's employment or circumstances
• Report to the Home Office if a worker does not show up, leaves, or is absent without explanation
• Retain payroll records and right-to-work documentation

Key personnel roles on the licence

Your licence application requires you to nominate individuals to specific roles. These are people within your organisation, not external advisers.

The Authorising Officer and key personnel must pass basic suitability checks. Anyone with relevant unspent criminal convictions, or who has previously been involved in a revoked licence, will be rejected.

4. Sponsor Licence Costs

There are three categories of cost to account for: the initial application fee, per-worker fees when you begin sponsoring, and ongoing charges.

Application fee

Small sponsor status is determined by Companies House data and HMRC records. A company qualifies as small if it meets at least two of: annual turnover of £10.2 million or less; balance sheet total of £5.1 million or less; 50 employees or fewer. Charities and educational institutions also qualify for the small sponsor fee.

Priority processing

An additional £500 buys priority processing, which aims for a decision within 10 working days rather than the standard 8 weeks. Priority processing does not change the outcome — it only affects speed. It is not a guarantee of approval, and the fee is non-refundable.

Per-worker costs

The Immigration Skills Charge applies to most Skilled Worker and intracompany transfer roles. It is a significant ongoing cost for employers who sponsor multiple workers over several years. For a medium-sized employer sponsoring one worker for five years, the ISC alone amounts to £5,000.

5. Application Process, Step by Step

The application is completed online through the Home Office's Sponsor a Worker service on GOV.UK. Before you begin, gather your documents and have your key personnel confirmed.

1. 1

   Confirm eligibility and vacancy genuineness

   Review the eligibility requirements and satisfy yourself that the roles you intend to fill meet the Skilled Worker visa criteria, including SOC codes and salary thresholds. If a Home Office caseworker questions the genuineness of the vacancy during assessment, you need to be prepared to evidence it.

2. 2

   Audit your HR systems

   Identify who will hold the Authorising Officer, Key Contact, and Level 1 User roles. Confirm you have record-keeping processes capable of meeting sponsor duties from day one of the licence being granted. The Home Office can and does conduct compliance visits shortly after a licence is granted.

3. 3

   Gather supporting documents

   The Home Office publishes a list of required documents based on your business type. Most employers must submit at least four documents, including evidence of registration, VAT registration (where applicable), employer's liability insurance, and evidence of a UK office.

4. 4

   Complete the online application

   The form covers your business details, the immigration routes you want to sponsor under, and details of your nominated personnel. It takes 1–2 hours for a straightforward application. There is no option to save and return mid-way through, so prepare thoroughly before starting.

5. 5

   Pay the application fee

   Payment is made online at the point of submission. The fee is non-refundable regardless of outcome. The priority processing fee is paid separately if you elect to use that service.

6. 6

   Await the decision

   Standard processing is approximately 8 weeks. The Home Office may request additional information during this period. Respond promptly — delays in response can slow the process or, in some cases, result in a refusal on procedural grounds.

7. 7

   Access the Sponsor Management System (SMS)

   On approval, your Level 1 User receives login credentials for the SMS. This is where you will assign Certificates of Sponsorship, report changes, and manage your licence. Set up your internal processes immediately — there is no grace period before your compliance obligations begin.

Common reasons applications are refused

• The Home Office is not satisfied the vacancy is genuine
• Nominated personnel have suitability issues
• Inadequate HR or record-keeping systems
• Insufficient documentation submitted
• Business address cannot be verified
• Previous licence refusal or revocation within the restricted period

6. Sponsor Duties and Ongoing Obligations

Obtaining a sponsor licence is not a one-off process. The licence comes with a set of ongoing legal duties, breach of which can result in downgrade, suspension, or revocation.

Record keeping

You must keep specific records for each sponsored worker throughout their employment and for a period after it ends. This includes:

• Passport and visa documentation
• Contact details including UK address
• National Insurance number
• A copy of the Certificate of Sponsorship
• Payslips (to evidence salary compliance)
• Attendance records for certain roles

Reporting duties

You must report specific events to the Home Office within prescribed timeframes via the SMS. These include:

• A sponsored worker not turning up for their first day — within 10 working days
• A sponsored worker being absent for more than 10 consecutive working days without permission — within 10 working days of that absence becoming apparent
• A sponsored worker leaving employment — within 10 working days
• Any significant change to the sponsored worker's employment, such as a change in role, salary, or working location

Cooperation with the Home Office

You must permit Home Office compliance officers to enter your premises, inspect records, and interview staff. Obstructing an officer or failing to cooperate will be treated as a serious compliance breach.

Genuine employment

Each sponsored worker must be performing the role described on their Certificate of Sponsorship. Using a sponsored worker for a different role, or for a third-party employer, is a serious breach. The Home Office does check.

7. Home Office Compliance Visits

The Home Office conducts compliance visits to sponsors — both announced and unannounced. These are sometimes referred to as inspections or audits. They can happen at any time, including shortly after a new licence is granted.

What officers look for

During a visit, a Home Office compliance officer will typically:

• Review personnel files for sponsored workers
• Check that records match what is recorded in the SMS
• Interview sponsored workers and, in some cases, line managers
• Verify that the roles being performed match the Certificate of Sponsorship
• Assess whether HR systems are adequate for your compliance obligations

What happens after a visit

Following a compliance visit, the Home Office will usually communicate whether they are satisfied with your compliance. Concerns may result in a formal action plan request, downgrade of your licence rating, or — in serious cases — suspension. Satisfactory visits generally require no further action.

8. Sponsor Licence Problems: Suspension and Revocation

Licence suspension

Suspension means the Home Office has concerns about your compliance. During suspension, you cannot assign new Certificates of Sponsorship. Your existing sponsored workers can usually continue to work, but their status is at risk if the licence is subsequently revoked.

Common causes of suspension include:

• Compliance visit identifying record-keeping failures
• Reports from HMRC or other government bodies about the employer
• Failure to report a worker's absence or departure
• Worker complaints or tip-offs to the Home Office
• Discrepancies identified in the SMS

Responding to suspension

The suspension letter will set out the grounds for concern and invite you to respond. Your response typically needs to include an action plan demonstrating that the issue has been identified, addressed, and that systems are in place to prevent recurrence. The quality of that response matters significantly — a generic response without specific evidence is unlikely to satisfy the Home Office.

Licence revocation

Revocation is the permanent removal of your sponsor licence. It is a serious outcome with significant consequences: all existing sponsored workers lose their permission to work in the UK and will need to make alternative arrangements. Your organisation is typically barred from applying for a new licence for at least 12 months.

Licence downgrade

A downgrade from an A-rated to a B-rated licence is a less severe outcome than suspension or revocation, but it still restricts your ability to take on new sponsored workers and requires an action plan to regain A-rating status. It is a formal signal that the Home Office has concerns about your compliance.
