Skilled Worker sponsor licence: what it covers and what it doesn't

A Skilled Worker sponsor licence is a sponsor licence with the Skilled Worker route on it. The route sits in the Home Office's "Worker" category, the licence costs £1,682 for a medium or large employer and £611 for a small or charitable one, and once granted it stays valid until it is revoked or surrendered. The catch is in paragraph L6.22 of the sponsor guidance: the routes you choose on your application "will then be the only routes on which you can sponsor workers."

For a business hiring into one kind of role, that sentence never matters. For a group that later wants to move a manager in from an overseas office, bring in a graduate trainee, or use the Scale-up route, it matters a lot, because most of the routes a growing employer reaches for next are not on a Worker licence at all. This guide sets out what the licence covers, what it doesn't, what adding the rest costs, and the structural decision that decides how far a compliance problem at one site can travel.

What a Worker licence actually covers

Part 1 of the Home Office sponsor guidance (version 08/26, published 28 August 2026) sorts every sponsored work route into two groups, "for convenience": Worker and Temporary Worker. You can apply to be licensed on as many routes as are appropriate for your organisation (L1.11), provided you are eligible for them (L6.22), and you can hold both types on the same licence. The Worker group has four routes (L1.14), and the Temporary Worker group has the rest (L1.15). GOV.UK's own types of licence page lists them the same way.

The Temporary Worker group also holds Creative Worker, Charity Worker, Religious Worker, Government Authorised Exchange, International Agreement, and Seasonal Worker.

The routes you reach for next are mostly Temporary Worker routes

Look at where the growth routes sit. Scale-up is a Temporary Worker route, even though it exists for fast-growing businesses hiring highly skilled people. Four of the five Global Business Mobility routes are Temporary Worker routes too. Only Senior or Specialist Worker, the successor to the intra-company transfer, sits alongside Skilled Worker in the Worker group.

So an employer that applied for Skilled Worker alone and later wants to second someone in on a client contract, or run a graduate programme with an overseas parent, has to add a route before it can assign a single Certificate of Sponsorship (CoS) on it. Adding a route is an application in its own right (the guidance's fee list refers to "applying to add routes", L6.12), and there are moments when the Home Office will not let you do it, which are covered below.

Three details to know before you plan around these routes:

• Every Global Business Mobility route requires you to register the linked overseas business the workers are assigned from (L5.7).
• Scale-up and UK Expansion Worker licences are time-limited. Every other licence is valid indefinitely, but you can only be licensed on those two routes for a maximum of four years (L3.8). A UK Expansion Worker sponsor must normally have established a UK trading presence and applied to add at least one other route within two years (L3.9).
• The Immigration Skills Charge applies to Senior or Specialist Workers as well as Skilled Workers, unless an exemption applies (L6.12). Budget for it on intra-company transfers the same way you would for a new hire.

What adding the other licence type costs

The fee depends on which type you hold first. These are the figures on GOV.UK's apply for your licence page as read on 30 September 2026.

The asymmetry looks like a penalty for doing things in the wrong order. It isn't. A medium or large employer that starts on Temporary Worker at £611 and later adds Worker at £1,071 has paid £1,682, exactly what it would have paid for both at once. The expensive part of a new route is never the licence line: it is the CoS fees, the Immigration Skills Charge where it applies, and the time it takes.

Two rules sit around those numbers. Your organisation size is not fixed at application: a Worker sponsor must report a change to its size or charitable status through the sponsorship management system (SMS), because it changes what you pay for licence fees and the Immigration Skills Charge (Part 3, C2.5). And the fee is yours to pay. Recouping the licence fee, including the fee for adding a route, or any associated administrative costs from a sponsored worker will normally lead to revocation (L6.17).

To see the licence fee in the context of everything that follows it, the Sponsor Licence Calculator totals the bill for your organisation, including the costs that arrive after approval.

When you cannot add a route

The worst time to discover a missing route is while your licence is under a B-rating and action plan. During the action plan period you cannot add branches or a new route to your licence, and you cannot assign a CoS to any new worker, though you can still assign one to a worker you were already sponsoring who needs to extend (Part 3, C8.15). A compliance problem at the wrong moment therefore freezes your expansion plans as well as your hiring.

The same logic applies to branches. The Home Office will not let you add a branch that holds a licence rated B or suspended, a branch whose licence was revoked in the past 12 months (24 months if it has been revoked more than once), or a branch it isn't satisfied can offer an eligible role (L5.8).

One licence or several: the decision that sets your blast radius

For an organisation with more than one site or UK entity, the bigger question is not which routes to hold but how many licences. Section L5 of Part 1 gives three options for offices, sites, UK subsidiaries, and related entities, all of which it calls branches (L5.5):

• a single licence covering your head office and all UK branches
• each branch applying for its own licence
• groups of branches under a single licence, for example all operations in one region

The guidance does not tell you which to choose. It tells you what happens when something goes wrong, and that is the part to put in front of your finance and legal colleagues. If you hold a single head office and all branches licence and it is downgraded to a B-rating or revoked, that applies to every branch, and on revocation none of them can sponsor anyone. The Home Office will normally cancel the permission of the workers you sponsor, because they are no longer working for a licensed sponsor (L5.10).

If your branches are individually licensed and one is revoked or downgraded, the others are not automatically revoked or downgraded, but the Home Office will investigate them (L5.9). Separate licences contain the damage. They don't make it disappear. Each one is also its own application with its own fee, and a branch that later applies for its own licence has any previous non-compliance taken into account (L5.11).

Whichever structure you hold, it has to stay accurate. New branches or sites, and new linked entities in the UK (or overseas, if you are on a Global Business Mobility route), are changes you report through the SMS (Part 3, C2.4), within 20 working days of becoming aware of them (C2.3). The Home Office may ask for evidence that a branch is linked by common ownership or control (L5.6).

Before you apply, decide three things

Paragraph L3.2 of Part 1 lists what to settle before you apply, and three of its points are the ones that shape everything above. First, which routes you need, not just this year's hire but the next two years of your hiring plan, because a route you leave off has to be applied for later, and cannot be added at all while you are on an action plan. Second, whether your branches hold one licence or several. Third, how many Certificates of Sponsorship you expect to assign in your first year on each route, which the application asks you to estimate and justify (L6.23). For Skilled Worker, that estimate is for Undefined CoS, the ones assigned to workers applying from inside the UK; CoS for workers coming from overseas are requested separately (L6.24). If the Home Office isn't satisfied with your reasons, it may give you a lower allocation or set it to zero (L6.26).

The application process itself, the documents, and the Key Personnel you need are in our sponsor licence application guide. If the Temporary Worker routes are the ones you're weighing, the Temporary Worker sponsor licence guide covers that side, and our map of the sponsor guidance shows which part of the Home Office's rulebook governs what.

The licence is the easy part

Most sponsors choose their routes once, on an online form the guidance says takes 20 to 30 minutes to complete (L6.21), and then live with that choice for years. The licence lasts indefinitely now, so the routes, branches, and linked entities on it have to keep pace with how the business actually hires. Borderless Immigration handles sponsor licence applications and the compliance work that follows them.
