GBM Service Supplier Visa: How UK Trade Agreements Enable Overseas Contractor Deployments

What Is the GBM Service Supplier Route?

The Service Supplier route is one of five sub-routes within the Global Business Mobility framework introduced in April 2022. It replaced elements of the former Tier 5 (Temporary Worker) scheme and the Tier 2 Intra-Company Transfer route for a specific category of deployment: the supply of services under a trade agreement commitment.

The Foundational Premise: Trade Agreement Commitments

Unlike every other UK visa route, the Service Supplier route is explicitly anchored to the UK's international trade commitments. The Home Office will only grant a Service Supplier visa where the deployment falls within a service sector and a bilateral or multilateral trade relationship that the UK government has formally committed to opening. The operative legal instrument is not solely the Immigration Rules it is the interaction between the Immigration Rules and the UK's trade agreement schedule.

Two Categories of Service Supplier

The route covers two distinct legal categories of applicant, each with different eligibility criteria.

Category 1 Contracted Service Supplier (CSS): An employee of an overseas company that has been awarded a service contract with a UK client. The overseas company is the service provider; the applicant is the employee being deployed to fulfil the contract. The overseas company does not need to hold a UK sponsor licence, but the UK based company receiving the services must hold the sponsor licence.

Category 2 Independent Professional (IP): A self-employed person who has been awarded a service contract with a UK client personally. The applicant supplies the services directly, without an employing company intermediary, but the requirement that the UK based company receiving the services hold a sponsor licence still remains.

The eligibility criteria differ between the two categories in several important respects, particularly around employment history, professional qualifications, and the nature of the contractual relationship.

Which UK Trade Agreements Enable the Service Supplier Route?

The Home Office publishes a list of trade agreements under which the Service Supplier route is available, along with the specific service sectors and nationalities covered under each agreement. Not all trade agreements confer Service Supplier rights, and not all service sectors are covered under every agreement. The operational coverage as of 2026 is as follows.

CPTPP: Comprehensive and Progressive Agreement for Trans-Pacific Partnership

The UK formally acceded to CPTPP in 2023. Service Supplier rights under CPTPP are available to nationals of member states (currently including Japan, Singapore, Malaysia, Vietnam, Australia, Canada, Chile, Mexico, New Zealand, Peru and Brunei, with others acceding) for a broad range of professional service sectors including legal, accounting, engineering, architecture, management consulting, and computer-related services.

UK & Switzerland MRA and Bilateral Agreements

The UK maintains bilateral trade and economic partnership agreements with Switzerland and a number of other countries that confer Service Supplier rights in specified sectors. The coverage and sector-specific commitments vary by agreement and must be checked against the applicable treaty schedule.

UK & India Free Trade Agreement (FTA) Framework

The UK–India FTA, under active negotiation and progressively implemented as of 2026, includes commitments on Mode 4 service supply (the WTO term for the temporary movement of natural persons to supply services). The specific sector coverage and eligibility conditions are determined by the UK–India FTA Annex and may differ from CPTPP commitments.

How to Check Coverage

Before advising a client or planning a deployment under the Service Supplier route, Global Mobility teams must verify: (1) the nationality of the applicant and whether that nationality falls within a qualifying trade agreement; (2) the specific service sector of the deployment and whether that sector is listed in the relevant trade agreement schedule; and (3) the applicable conditions (minimum years of experience, qualification requirements, and maximum stay permitted under the specific agreement). The Home Office publishes this information in the Guidance on the Global Business Mobility routes, Annex: Trade Agreement Commitments.

Contracted Service Supplier (CSS): Eligibility in Detail

For the Contracted Service Supplier category, the following requirements must all be met at the date of application.

Requirement 1: Employment with the Overseas Company

The applicant must be employed by the overseas service-supplying company. They must have been employed by that company for at least 12 months prior to the date of application (or for a shorter period if specified in the applicable trade agreement schedule). The employment must be genuine and ongoing, the role must not have been created for the purpose of facilitating the application.

Requirement 2: The Service Contract

There must be a genuine contract for services between the overseas company and a UK client for the supply of services in an eligible sector. The contract must be in existence at the date of application. The applicant's role under the deployment must be directly related to fulfilment of that contract.

Requirement 3: Salary Threshold

The applicant must be paid at least £26,200 per year, or the going rate for the occupation as specified in the Immigration Rules, whichever is higher. This salary must be paid by the overseas employer throughout the deployment it is not the responsibility of the UK client.

Requirement 4: Sector and Qualification Eligibility

The deployment must fall within a service sector listed in the applicable trade agreement schedule. Many agreements also require the applicant to hold relevant professional qualifications or a degree in a related field. The specific qualification requirements vary by sector and by agreement.

Requirement 5: No Requirement for a UK Sponsor Licence

This is one of the most commercially significant features of the Service Supplier route. Unlike the Skilled Worker, Senior or Specialist Worker, and most other GBM sub-routes, the Service Supplier route does not require the UK client company to hold a sponsor licence. The UK client is not the sponsor, there is no sponsorship relationship at all. The overseas employer is responsible for the applicant's compliance with the visa conditions.

Independent Professional (IP): Eligibility in Detail

The Independent Professional category has a number of additional requirements compared to the CSS category, reflecting the greater compliance risk associated with self-employed applicants.

Self-Employment and Company Ownership

The applicant must be self-employed in their home country or country of establishment. They must not be placed by a staffing agency or employment business. Where the applicant trades through a company of which they are the majority owner, the Home Office treats this as the equivalent of self-employment for these purposes.

Professional Experience Requirement

Most trade agreements impose a minimum period of professional experience in the relevant sector as a condition of the IP category — commonly six years, though this varies by agreement and sector. This is significantly more demanding than the 12-month employment requirement for the CSS category.

The Service Contract Requirements for IPs

The service contract for an IP must specify the services to be supplied, the duration of the engagement, and the fee payable. The contract must be with an end-client in the UK not with an intermediary or agency. This requirement addresses the risk of disguised employment relationships, which the Home Office treats as a fundamental breach of the route's conditions.

No Recourse to Public Funds

Independent Professionals on the Service Supplier route, like all GBM route applicants, are subject to a no recourse to public funds (NRPF) condition. They may not claim most UK welfare benefits, social housing, or other public funds during their deployment.

Service Supplier vs Secondment Worker vs Business Visitor: Choosing the Right Route

One of the most frequent errors in Global Mobility planning is selecting the wrong route for a deployment. The Service Supplier, Secondment Worker, and Business Visitor routes all cover scenarios involving overseas personnel providing services in the UK, but they are legally and operationally distinct.

The Business Visitor Trap

The most common compliance error is deploying an overseas contractor or specialist to the UK on a standard Business Visitor visa to perform substantive service delivery work. A Business Visitor may attend meetings, negotiate contracts, and undertake certain permitted activities but may not provide services or supply labour under contract to a UK client. This constitutes illegal working and exposes both the individual and the UK client to serious immigration penalties. Where a deployment involves substantive service delivery, the Service Supplier or Secondment Worker route must be used.

Duration, Extension and the ILR Ineligibility Problem

Maximum Duration of Stay

The maximum period of stay on the Service Supplier route varies depending on the applicable trade agreement and the category of applicant. Under most agreements, the maximum is 12 months in any 24-month period. Some agreements provide for shorter maximum stays. The duration is not extendable beyond the maximum permitted under the applicable agreement this is a hard cap, not a guideline.

Multiple Entries and the 24-Month Rolling Period

Unlike some visa routes, the Service Supplier visa may allow multiple entries within the authorised period. However, Global Mobility teams must track carefully against the relevant agreement's maximum stay provisions, as breaching the allowable period is a compliance breach that can affect future applications under any route.

ILR Ineligibility: A Critical Long-Term Planning Point

The Service Supplier route does not lead to Indefinite Leave to Remain. Time spent in the UK on a Service Supplier visa does not count towards the five-year continuous residence requirement for ILR under any route. This is a fundamental distinction from the Senior or Specialist Worker route (the only GBM route that leads to settlement) and from the Skilled Worker route.

For multinationals considering deploying a specialist to the UK on a long-term or permanent basis, the Service Supplier route is not appropriate beyond its maximum permitted duration. Where long-term presence or settlement is the strategic objective, the Senior or Specialist Worker or Skilled Worker route with their associated sponsor licence requirements must be planned from the outset.

ILR Ineligibility and Long-Term Deployment Planning for HR

From a Global Mobility strategy perspective, the Service Supplier route is best understood as a short-term deployment mechanism rather than a long-term presence pathway. For HR Directors and Global Mobility teams managing complex international assignments, the following planning considerations apply.

Assignment Lifecycle Planning

A Service Supplier deployment should be planned against the maximum permitted stay under the applicable trade agreement. At the point where the assignment is expected to exceed that maximum or where the business need shifts from project-specific service delivery to ongoing operational presence the deployment must transition to a different route. The most common transition is from Service Supplier to Senior or Specialist Worker (requiring a sponsor licence with K rating) or Skilled Worker.

The Sponsor Licence Investment Decision

The absence of a sponsor licence requirement for Service Supplier deployments is commercially attractive for short-term assignments. However, for companies that regularly deploy overseas specialists to the UK on a recurring basis, the investment in obtaining and maintaining a sponsor licence for the Senior or Specialist Worker or Skilled Worker route may be more commercially rational in the medium term, given the greater flexibility, longer duration, and settlement eligibility those routes provide.

Tax and Employment Law Interaction

A Service Supplier deployment does not change the applicant's employment status for UK tax and employment law purposes. The overseas employer remains the legal employer. However, where a deployment exceeds 183 days in a UK tax year, UK PAYE obligations may arise for the overseas employer. Global Mobility teams should ensure that tax advice is obtained alongside immigration advice for all Service Supplier deployments of significant duration.

Frequently Asked Questions

Does the UK client need to do anything to sponsor a Service Supplier visa?

No. The Service Supplier route does not require the UK client to hold a sponsor licence or to take any formal sponsorship action. The application is made by the overseas company or the individual. However, the UK client must provide evidence of the service contract, which is a mandatory document in the application.

Can a Service Supplier visa holder bring dependants to the UK?

Yes. Dependants (spouse or partner and children under 18) of a Service Supplier visa holder may apply for a Dependant visa to accompany or join the main applicant in the UK, provided the main applicant meets the financial maintenance requirements for dependants.

What happens if the service contract is terminated early?

If the service contract is terminated before the visa expires, the legal basis for the deployment no longer exists. The visa holder should not continue to supply services in the UK. The Home Office should be notified. The visa holder may remain in the UK until the expiry date of their visa but must not engage in further service delivery under the terminated contract.

Is the Service Supplier route available to all nationalities?

No. Eligibility depends on the nationality of the applicant and the trade agreements to which their country of nationality or establishment is a party with the UK. Nationals of countries with which the UK has no qualifying trade agreement covering the relevant service sector are not eligible for this route.

Can a Service Supplier visa holder switch to a Skilled Worker visa?

Yes, in principle. A Service Supplier visa holder who is offered a job with a UK employer holding a valid sponsor licence may apply to switch to a Skilled Worker visa from within the UK, subject to meeting all the Skilled Worker eligibility requirements at the date of the switching application.

What are the most common reasons for Service Supplier visa refusals?

The most common refusal grounds are: the deployment does not fall within a service sector covered by the applicable trade agreement; the service contract does not meet the required specifications; the applicant does not have the required minimum period of employment or experience; the salary evidence is insufficient; or the application was made without professional legal assistance and key evidential requirements were not addressed.
