Immigration Skills Charge rates have risen faster than many sponsors' hiring budgets have kept pace with, and the increase applies per year of Certificate of Sponsorship validity, so a rate rise multiplies across every year of a multi-year sponsorship rather than hitting once.
Why the charge went up
The ISC was introduced to encourage employers to invest in training the resident workforce rather than defaulting to sponsored recruitment, and rate increases have generally been framed the same way — as a lever to make sponsorship reflect its real cost. The current rate sits within the wider set of sponsor licence fees and salary rules covered in the government's sponsor duties and compliance guidance, which is the only place to confirm the number that actually applies on the date you assign a certificate.
How the charge is actually structured
The ISC isn't a flat one-off fee — it's charged per Certificate of Sponsorship, scaled by how many years the certificate covers, and the amount differs depending on whether the sponsoring organisation qualifies as a small or charitable sponsor versus a medium or large one. A certificate covering part of a year is generally rounded up to the next full year for charging purposes rather than charged pro rata, which catches out sponsors who assume a nine-month assignment will cost proportionally less than a full one. None of this changes the direction of a rate increase, but it does mean two employers sponsoring what looks like the same role can end up facing different totals, so it's worth confirming your organisation's size classification is still current before you budget — a company that's grown since its licence was first assessed may no longer sit in the band it did when someone last checked.
Recalculating cost per hire
An increase changes more than the invoice — it changes the real all-in cost of a sponsored hire, which should sit alongside salary when you're deciding whether a role clears your internal hiring bar. For roles assessed against going rate thresholds, it's worth modelling the ISC as a fixed multi-year overhead on top of salary, not a rounding error, particularly for three-to-five-year certificates where the charge compounds across every sponsored year. It's worth checking the role against the current salary floor at the same time, since both figures tend to move on similar timelines and a role that cleared the bar last year may need a fresh salary check this year, before the ISC is even added on top.
What the charge can't be used to cover
Sponsor guidance is explicit that the Immigration Skills Charge must be paid by the sponsor and must not be recovered from the sponsored worker, whether through a direct deduction or indirectly by making it a condition of the job offer. This matters for budgeting in a very direct way — the full charge sits on the employer's books as a genuine cost of hiring, and any arrangement that shifts even part of it back to the worker is a compliance risk in its own right, not a legitimate way to soften the impact of an increase.
Sectors where this bites hardest
Volume sponsors — care providers, hospitality groups, logistics operators — feel rate increases disproportionately because they're sponsoring at scale across roles that are often close to margin already. Care sector employers working through care worker sponsorship requirements in particular need to re-run their per-hire cost model whenever the rate moves, since a small per-year increase applied across dozens of overseas hires adds up to a material line in the annual budget.
Forecasting across a renewing cohort
The budgeting mistake that's easy to make is treating the ISC as a one-time hiring cost rather than a recurring one. Every certificate renewal — a promotion, a role change, or simply reaching the end of a worker's current permission — triggers a fresh ISC charge at whatever rate applies on that future date, not the rate paid originally. A sponsor with a large cohort of overseas staff approaching renewal in the same window can face a cluster of charges landing in a single quarter, at a rate that may be higher than the one budgeted for when those workers were first sponsored. Mapping renewal dates across your whole sponsored population, not just tracking new hires, is the difference between an increase being a manageable line item and an unbudgeted surprise.
Building rate changes into your process
Don't rely on remembering the rate from last year's hiring round. Bake a rate check into whatever step assigns a Certificate of Sponsorship, so the current figure is pulled fresh each time rather than copied from an old spreadsheet — this is exactly the kind of drift that sponsorship compliance software is designed to catch before a certificate goes out at the wrong cost. It's also worth setting a reminder tied to renewal dates rather than only new-hire dates, so finance sees an upcoming ISC liability before the certificate is assigned rather than after the invoice lands.
FAQs
Does the increase apply to certificates already assigned before the change?
No — the rate in force on the date a Certificate of Sponsorship is assigned is the one that applies; certificates assigned earlier aren't retrospectively charged more.
Does a rate increase affect the salary threshold a role must meet?
No, the ISC and the minimum salary requirement are assessed separately — a rate rise doesn't change what salary a role needs to clear, only what the certificate itself costs.
Can we pass any part of the Immigration Skills Charge on to the sponsored worker?
No — the charge must be met by the sponsor, and recovering it from the worker in any form is treated as a breach of sponsor duties rather than a legitimate budgeting workaround.
Does extending a worker's visa trigger the charge again?
Yes — an extension generally requires a new Certificate of Sponsorship, and the ISC is payable again at whatever rate applies on the date that new certificate is assigned, not the rate paid on the original one.
