For HR teams managing international hires on the UK Skilled Worker route, the five-year ILR window is a predictable event — but it requires proactive tracking to navigate cleanly. This article covers the eligibility criteria HR teams need to monitor, the employer-side obligations that affect ILR outcomes, and what to build into your HR workflows to support employees approaching settlement.
The ILR eligibility framework
Indefinite Leave to Remain (ILR) — formally referred to as "settlement" in UK immigration law — is the status that grants the right to live and work in the UK without immigration restrictions. For Skilled Worker route holders, the qualifying period is five continuous years of lawful residence.
The key compliance variables HR needs to track:
1. Continuous residence — the rolling absence threshold
The Home Office applies a 180-day absence rule. Absences from the UK must not exceed 180 days in any 12-month period within the qualifying five years. The critical detail: the Home Office evaluates every possible 12-month window within the qualifying period — not just calendar years or windows rolling from the entry date.
In practice, if an employee took a 90-day absence in the second year and another 100-day absence in the third year, the overlap between those periods in a single rolling 12-month window may cause a breach — even if neither individual year exceeds 180 days.
HR should maintain accurate records of international travel for sponsored workers, particularly extended leaves or remote working arrangements from abroad. Many organisations extend hybrid-working agreements without flagging overseas periods to immigration compliance teams.
What to build into your HR system:
- A travel log per sponsored employee with departure/return dates
- A rolling 12-month absence calculator that checks all windows in the qualifying period, not just calendar years
- Alerts when cumulative absences within any 12-month window exceed 150 days (early warning threshold)
2. Sponsor licence status continuity
An employee's ILR application will be assessed against the employer's sponsor licence status throughout the qualifying period. A licence suspension, revocation, or downgrade during the five-year window can complicate an ILR application — even if the licence was later reinstated.
HR teams should maintain an internal audit log of any UKVI compliance actions against the licence, including civil penalty notices, Sponsor Management System (SMS) changes, or formal notifications from the Home Office.
Practical check: Before an employee submits their ILR application, verify the employer's sponsor licence is currently listed as "Active" on the Register of Licensed Sponsors. Tools like ImmigrationGPT provide a searchable interface to check sponsor status in real time.
3. Salary and occupation code compliance at point of application
At the point of ILR application, the employee's current salary must still meet the going rate for their Standard Occupational Classification (SOC) code under the current Home Office thresholds — not the thresholds that applied when the original CoS was assigned.
Going rate requirements are updated periodically. Employees whose roles have changed internally — promotions, internal transfers, function changes — should have their SOC code reviewed. If the occupation has changed materially, a new Certificate of Sponsorship may need to be assigned before the ILR application is submitted.
HR workflow addition:
- Include a going rate salary check in the annual salary review process for all employees within two years of their ILR qualifying date
- Flag where an employee's job title or function has diverged from their original SOC code
4. Gap in lawful leave
A gap in continuous lawful leave — even a single day where leave expired before a renewal application was received — breaks the continuity requirement. This is distinct from absence abroad; it's about the unbroken chain of permission to be in the UK.
HR should track visa expiry dates and send extension reminders at least six months before expiry. UKVI processing times for Skilled Worker renewals are typically two to eight weeks, but delays can occur. A 28-day buffer before submission is a common compliance standard.
5. Criminal record disclosure
ILR applications require disclosure of criminal convictions or cautions received during the qualifying period (spent convictions are generally excluded). HR does not hold this data, but compliance leads should advise employees approaching ILR to seek legal advice if any incidents occurred during their qualifying period.
Pre-application compliance review checklist
Initiate this review at least six months before the five-year anniversary:
- Export full absence record; run rolling 180-day calculation across all 12-month windows
- Confirm employer sponsor licence is "Active" on the Register of Licensed Sponsors
- Confirm current salary meets going rate for current SOC code
- Confirm no gap exists in the employee's continuous leave record
- Confirm employee's role/SOC code is still consistent with the original CoS
- Advise employee to obtain legal advice on any criminal record disclosures
After ILR is granted
Once an employee holds ILR, the sponsor obligation ends — they no longer need to be sponsored. HR should:
- Update the HR system to reflect the change in immigration status
- End sponsor monitoring obligations for that employee
- Advise the employee that ILR lapses if they remain outside the UK for more than two consecutive years
ILR holders can apply for British citizenship after a further 12 months (subject to other requirements), which HR may be asked to support with employment reference documentation.
