Sponsor licence costs · Immigration Skills Charge

The Immigration Skills Charge, in plain English — and what it actually costs your business.

Direct answer

The Immigration Skills Charge (ISC) is a per-worker fee UK sponsors pay to the Home Office when they assign a Certificate of Sponsorship under the Skilled Worker route and most other work routes. Small or charitable sponsors pay £480 for the first 12 months and £240 for each additional 6 months. Medium and large sponsors pay £1,320 for the first 12 months and £660 for each additional 6 months. The charge is paid in full upfront at CoS assignment and cannot be passed on to the worker — doing so can lead to your sponsor licence being revoked.

Who this applies to: UK employers planning to sponsor a worker under the Skilled Worker route, the Senior or Specialist Worker route (Global Business Mobility), or any other work route where the Immigration Skills Charge applies.

Who pays the ISC

Which employers pay the Immigration Skills Charge.

If your business sponsors a worker under the Skilled Worker route, you almost always pay the Immigration Skills Charge. The size of your business decides the rate you pay — not the salary or seniority of the role.

UK employers sponsoring workers under the Skilled Worker route
UK employers sponsoring under the Senior or Specialist Worker route (Global Business Mobility) — subject to specific exemption conditions
Sponsors of any size — the small-sponsor rate is automatic if you meet the size test
Charities — automatically pay the small/charitable rate regardless of headcount or turnover
Most SME employers fall squarely inside the charge

Worked example

Example: medium-sized UK employer hiring one Skilled Worker for 3 years.

First 12 months
Charged at the medium/large rate at CoS assignment.
£1,320
Months 13–18
First additional 6-month block.
£660
Months 19–24
Second additional 6-month block.
£660
Months 25–30
Third additional 6-month block.
£660
Months 31–36
Fourth additional 6-month block.
£660
Total ISC due upfront at CoS assignment
Paid in full when the CoS is assigned — not annually in arrears.
£3,960

A small or charitable sponsor would pay £480 + (4 × £240) = £1,440 for the same 3-year sponsorship period. A medium/large sponsor on a 5-year CoS would pay £1,320 + (8 × £660) = £6,600 upfront.

The non-negotiable rules

When it is paid, who pays — and why you cannot recover it from the worker.

The Immigration Skills Charge is paid by the sponsor at the moment a Certificate of Sponsorship is assigned through the Sponsor Management System. It is paid in full, upfront, for the entire sponsorship period — not annually in arrears.

Paid by the sponsoring employer at CoS assignment, not when the worker arrives
Paid in full upfront for the entire sponsorship period
Cannot be deducted from the worker's salary
Cannot be recovered through repayment-on-leaving or clawback clauses
Home Office position is explicit: a sponsor licence can be revoked for asking the worker to pay the ISC or any other linked application costs
Exemptions and refunds

When the ISC is not payable — and when you can claim it back.

A small number of routes and circumstances are exempt from the Immigration Skills Charge. We recommend you take advice before assuming an exemption applies to your hire — exemption rules are tightly defined and have been updated several times.

PhD-level occupations in research and science (SOC codes 2111–2119, 2161, 2162) and higher education teaching professionals (SOC 2311)
Workers assigned a Certificate of Sponsorship before 6 April 2017
Dependants of sponsored workers (partners and children)
Some study-to-work switches on extension applications
Global Business Mobility Senior or Specialist Worker route — subject to specific conditions on CoS date, nationality and assignment duration
Refunds are paid in full where the worker's visa is refused, the application is withdrawn, or the worker never enters the UK to start work
Partial refunds apply where the worker receives a shorter visa, changes sponsor, or leaves the sponsorship early
What goes wrong

The five Immigration Skills Charge mistakes we see most often.

Budgeting only the licence application fee and forgetting the ISC entirely — then discovering at CoS assignment the per-worker cost is much higher than expected
Assuming the ISC is paid annually in arrears, when it is actually paid in full upfront at CoS assignment
Assigning a CoS for longer than the role really needs, locking the business into a higher upfront ISC than necessary
Trying to recover the ISC from the worker through salary deductions or clawback clauses — a compliance breach that can put the entire sponsor licence at risk
Forgetting that the small-sponsor rate is automatic for charities — and overpaying because the size test was not checked at application

Common questions

Questions employers ask us.

Small or charitable sponsors pay £480 for the first 12 months of sponsorship and £240 for each additional 6 months. Medium and large sponsors pay £1,320 for the first 12 months and £660 for each additional 6 months. The full amount is paid upfront at Certificate of Sponsorship assignment.

The employer pays it in full. The Home Office's published guidance is explicit: the sponsor must pay the Immigration Skills Charge and cannot ask the worker to pay it. Trying to recover the charge from the worker — through salary deductions, clawback clauses, or any other route — can lead to the sponsor licence being revoked.

At the point you assign the Certificate of Sponsorship through the Sponsor Management System. You pay the full charge for the entire sponsorship period at that moment, not annually in arrears.

You qualify as a small sponsor if you meet at least two of three tests: annual turnover of £15m or less, total assets of £7.5m or less, or 50 employees or fewer. Registered charities qualify automatically, regardless of size. All other employers pay the medium/large rate.

Yes, but they are narrow. The most common exemptions cover PhD-level science and higher education roles (specific SOC codes), Certificates of Sponsorship issued before 6 April 2017, dependants, certain study-to-work switches on extension, and some Senior or Specialist Worker assignments under Global Business Mobility. We recommend you take advice before assuming an exemption applies to your hire.

Refunds are possible in defined circumstances. You receive a full refund if the worker's visa is refused or withdrawn, or the worker never enters the UK to start work. You receive a partial refund where the worker is granted a shorter visa than the period charged for, changes sponsor, or leaves sponsorship early. Refunds are processed by the Home Office on its own timescale.
