TL;DR
The UK Scale-Up visa allows a sponsored worker to leave the sponsoring employer after 6 months and continue working in the UK without a new sponsor licence. The Skilled Worker visa does not - leaving the sponsor cancels the visa unless the worker is switched to a new sponsor's certificate within 60 days. Scale-Up requires a salary of at least £36,300 plus the going rate, and the sponsor must show year-on-year growth of 20 percent in turnover or staff headcount over the prior 3 years. Both routes lead to ILR after 5 years.

The Scale-Up route: 6 months tied, then free
The Scale-Up visa launched on 22 August 2022 and is designed to help high-growth UK firms recruit overseas talent without locking either party into a long-term sponsorship relationship. The applicant needs a Certificate of Sponsorship from a Scale-Up sponsor, English language at CEFR B1, and a job at RQF Level 6 (graduate equivalent) paying at least £36,300 plus the published going rate for the occupation code. The visa is granted for 2 years on the initial application, of which the first 6 months are tied to the sponsor: the holder must remain employed by the sponsor and in the sponsored role during that period. After 6 months, the holder is free to leave the sponsor and continue working in the UK on the Scale-Up visa in any role for any employer, including self-employment or unsponsored employment, until the leave expires. Extensions are available in 3-year blocks based on PAYE earnings of at least £36,300 in at least 12 of the preceding 24 months, and the route leads to settlement after 5 years of continuous residence.
The Skilled Worker route: sponsor-tied throughout
The Skilled Worker visa, by contrast, ties the holder to the sponsor for the entire duration of the grant. Leaving the sponsoring employer, or having the sponsorship withdrawn, triggers a 60-day cure period in which the holder must either find a new sponsor and submit a fresh application or leave the UK. The route requires a job at RQF Level 3, a salary above the general threshold of £38,700 (with lower thresholds for the Immigration Salary List, new entrants and certain health and education roles), English at CEFR B1, and a Certificate of Sponsorship from a Worker sponsor licence holder. Detailed cost mechanics including IHS, biometric and priority service add-ons are set out in the UK Skilled Worker visa cost guide. The Skilled Worker route leads to ILR after 5 continuous years, and unlike Scale-Up, time spent unemployed or in non-sponsored work does not count toward the 5 years.
Side-by-side comparison: fee, threshold, ILR period, conditions
The two routes are most easily compared by what each requires at each stage of the visa lifecycle. The figures below apply to an outside-UK applicant, standard occupation, April 2025 fee schedule.
- Sponsor licence type: Scale-Up sponsor licence (with growth test) vs Worker sponsor licence.
- Sponsor growth test: Scale-Up sponsors must show 20 percent year-on-year growth in turnover or staff headcount over the most recent 3 financial years, and at least 10 employees at the start of that 3-year period. The Skilled Worker route has no growth test.
- RQF level: Scale-Up RQF Level 6 (graduate), Skilled Worker RQF Level 3.
- Salary threshold: Scale-Up £36,300, Skilled Worker £38,700 general.
- Going-rate requirement: both routes require 100 percent of the going rate for the occupation code.
- English language: both require CEFR B1.
- Initial leave granted: Scale-Up 2 years, Skilled Worker up to 5 years on the CoS.
- Tied period: Scale-Up 6 months sponsor-tied then free. Skilled Worker tied throughout, 60-day cure on sponsorship loss.
- Application fee, outside UK 3 years: Scale-Up £331, Skilled Worker £719 standard.
- Immigration Health Surcharge: £1,035 per adult per year on both routes.
- Extension test: Scale-Up requires PAYE earnings of £36,300 in 12 of the preceding 24 months. Skilled Worker requires a fresh CoS from a current sponsor.
- Settlement: both lead to ILR after 5 years of continuous residence.
The Scale-Up application fee is notably lower than Skilled Worker, reflecting the policy design intent of lowering barriers for high-growth recruiters and the workers they want to attract.
Which fits which applicant
For an applicant whose plan is to take a single role at a UK scale-up and stay in that role for the long term, the Skilled Worker route is arguably simpler because the visa duration is set by the Certificate of Sponsorship and the extension paperwork is handled by the employer. For an applicant whose plan is to use the first role as an entry point to the UK labour market - perhaps to launch a side venture after 6 months, change employers freely, or pivot to self-employment - the Scale-Up route is structurally far superior, because after the 6-month tied period the visa decouples entirely from the sponsor. The Scale-Up route is also a sensible choice for applicants whose sponsoring firm is itself a higher-risk bet: if the scale-up fails or downsizes within the 2-year initial grant, the holder is not forced to leave the UK at the point the company collapses, provided the 6-month tied period has elapsed. The trade-off is the narrower sponsor pool: only firms that meet the growth test can sponsor Scale-Up applicants, so the universe of available roles is smaller than under Skilled Worker.
Cost comparison and the calculator
On a single-applicant 2-year initial grant outside the UK, a Scale-Up applicant pays £331 in application fee plus £2,070 IHS plus £19.20 biometric enrolment, totalling £2,420.20. The Skilled Worker equivalent for a 2-year-equivalent grant is £719 plus £2,070 IHS plus £19.20, totalling £2,808.20. The Scale-Up route is roughly £400 cheaper at the visa stage. On a 5-year settlement journey the totals are closer: Scale-Up pays the initial £331 plus an extension fee at month 24 plus ILR at month 60, while Skilled Worker pays the initial £719 plus the ILR application. The UK visa fee calculator models both routes including dependants. For the applicant, the cost difference is not what should drive route choice: the structural flexibility difference (6-month tied period then free vs sponsor-tied throughout) is the deciding factor in almost every case, and the Scale-Up applicant fee is roughly the same as one month's rent in London, so price comparisons do not move the needle.
Frequently asked questions
Which UK firms qualify as Scale-Up sponsors?
A firm qualifies as a Scale-Up sponsor by holding a Scale-Up sponsor licence, which requires evidence of at least 20 percent year-on-year growth in either turnover or staff headcount over the most recent 3 financial years, and a starting headcount of at least 10 employees at the beginning of that 3-year period. The Home Office publishes a register of licensed sponsors that identifies which firms hold Scale-Up sponsor status. The licence is renewed every 4 years.
What is the Scale-Up salary threshold?
The Scale-Up salary threshold is £36,300 per year plus the published going rate for the occupation code, whichever is higher. The threshold applies at the point of initial application and at extension, where the applicant must show PAYE earnings of at least £36,300 in at least 12 of the 24 months preceding the extension application. The figure is the higher of either the general threshold or the going rate, so for high-paying occupations the going rate sets the floor.
Can a Scale-Up visa lead to UK settlement?
Yes. The Scale-Up route leads to Indefinite Leave to Remain after 5 continuous years of qualifying residence. Time spent on Scale-Up counts toward the 5 years provided the holder meets the extension PAYE earnings test at each extension point, and provided absences from the UK in any 12-month period do not exceed 180 days. The ILR application itself uses the standard settlement fee, currently £2,885.
Can a Scale-Up holder switch to Skilled Worker after the 6 months?
Yes. A Scale-Up holder can switch into the Skilled Worker route from inside the UK by obtaining a Certificate of Sponsorship from a Worker sponsor licence holder and submitting an inside-UK Skilled Worker application. The application fee is £827 for a grant of up to 3 years, plus the standard IHS, and the 5-year ILR clock continues to run from the original Scale-Up entry date provided the residence has been continuous.
Why is the Scale-Up visa less popular than Skilled Worker?
Scale-Up grants run well below Skilled Worker volumes for two structural reasons. First, the sponsor pool is narrower: only firms meeting the growth test can sponsor, and many high-growth UK firms use Skilled Worker sponsorship out of habit or because their HR systems are set up for it. Second, awareness in overseas labour markets is lower: the Skilled Worker route is the default presented by international recruiters, and applicants often do not know the Scale-Up option exists until a UK-based recruiter raises it.
