The True Cost of Sponsoring a Worker in 2026: Immigration Skills Charge, Fees and the Numbers HR Forgets
Most employers budget for a sponsored hire by looking at the salary and maybe the visa fee. Then the real bill arrives. The Immigration Skills Charge (ISC) — the single biggest hidden cost of sponsorship — rose by 32% on 16 December 2025 , and it is charged per worker for every year of sponsorship , paid up front. If your hiring budget still uses last year's numbers, you are underestimating the cost of every sponsored role.

Skilled Worker sponsor licence
Licence fees, sponsor duties and how we help you apply.
Find out moreThis post lays out the true, all-in cost of sponsoring a Skilled Worker in 2026, who actually pays each charge, and where the genuine exemptions are. It is written for employers and HR teams, not lawyers — so we define terms as we go.
What is the Immigration Skills Charge, and who pays it?
The Immigration Skills Charge is a fee the government levies on employers who sponsor most Skilled Worker and Senior or Specialist Worker visa holders. The policy aim is to nudge employers to train domestic workers rather than rely on overseas recruitment.
The critical point: the ISC is the sponsor’s cost. You cannot lawfully pass it on to the worker. Trying to recover it from the employee — by deduction, side agreement, or otherwise — puts your sponsor licence at risk.
How much did the Immigration Skills Charge increase in December 2025?
For Certificates of Sponsorship assigned on or after 16 December 2025, the rates rose by 32%:
| Sponsor type | First 12 months | Each further 6 months | 5-year total |
|---|---|---|---|
| Medium / large sponsor | £1,320 | £660 | £6,600 |
| Small or charitable sponsor | £480 | £240 | £2,400 |
So sponsoring one worker for a five-year visa now costs a large employer £6,600 in ISC alone (up from £5,000), and a small employer £2,400 (up from £1,820) — before a single other fee.
Status note: Rates reflect the position from 16 December 2025 and apply to CoS assigned on or after that date. Always confirm the current figures and your sponsor-size classification before budgeting a hire.
The true cost of sponsoring a worker in the UK: the full stack
The ISC is only one line. Here is the realistic cost stack for a sponsored Skilled Worker, and who pays each part:
- Sponsor licence fee (one-off, to hold a licence at all) — the employer.
- Certificate of Sponsorship fee (per worker) — the employer.
- Immigration Skills Charge (per worker, per year) — the employer, non-recoverable.
- Visa application fee — the worker, though employers often cover it as part of the package.
- Immigration Health Surcharge (IHS) (per year of the visa) — the worker, again frequently absorbed by employers.
For a single five-year hire by a large sponsor, the employer-side mandatory costs (licence apportioned, CoS and ISC) run into several thousand pounds before you add anything you choose to cover for the worker. The lesson HR teams learn the hard way: sponsorship is a multi-thousand-pound commitment per head, not a form-filling fee.
Who is exempt from the Immigration Skills Charge?
There are real exemptions — and missing them means overpaying. The ISC generally does not apply in cases including:
- Workers sponsored in certain research and higher-education occupation codes specified by the Home Office.
- Some applicants switching from the student route to Skilled Worker may be exempt from the Immigration Skills Charge where the specific Home Office exemption requirements are met.
- Workers applying from outside the UK for a visa of less than 6 months.
Whether an exemption applies is fact-specific and tied to the exact occupation code and the worker’s history. Confirm it before you assign the CoS, because the charge is taken up front based on the sponsorship period.
The “going rate” multiplier most budgets miss
Cost is not just the ISC. Since 22 July 2025, the salary floor for many roles is higher — the general threshold is £41,700, and you must pay the higher of that or the role’s going rate. So the true cost of a sponsored hire is often a higher salary plus the increased ISC plus the other fees, stacking together. (For the salary and skill-level changes, see our guide to Skilled Worker sponsorship after July 2025.)
Equipping HR to defend the budget to the C-suite
If you have to justify these costs to a CFO, give them the one-line version: sponsorship in 2026 is a deliberate, multi-thousand-pound-per-head investment, not a routine admin cost — and the ISC alone now adds up to £6,600 over a five-year hire for a large employer. Budget it as a strategic spend reserved for business-critical roles, plan the exemptions properly, and keep your compliance tight so the investment isn’t lost to a licence problem. (See our guide on how to handle a Home Office compliance visit.)
Bottom line
The December 2025 increase made an already significant cost materially heavier. Employers who model the full stack — licence, CoS, ISC, and any worker costs they absorb — and who check exemptions before assigning each CoS, make better hiring decisions and avoid nasty surprises. Those who budget on salary alone keep getting caught out.
