When Can I Apply for ILR? How to Calculate Your Qualifying Date

The 28-day rule for ILR timing is a mathematical trap. You can submit your ILR application up to 28 days before the qualifying period for your route is completed — but applying even one day before that window opens results in automatic refusal, and the £3,226 application fee is not refunded if the application is refused.

The calculation sounds simple. It isn't.

How the 28-Day Window Works

Your ILR qualifying period can be 3, 5, 10, 15, or 20 years, depending on your route and qualifying factors. The 28-day window opens exactly 28 days before the date you complete that qualifying period.

Example for a Skilled Worker applicant whose applicable qualifying period is 5 years: If your qualifying period started on June 15, 2021, you complete five years on June 15, 2026. The 28-day window opens on May 18, 2026 (28 days before June 15). The earliest you can submit is May 18, 2026. Submitting on May 17 is too early and results in automatic refusal.

The Harder Question: Which Date Does Your Qualifying Period Start From?

This is where applicants go wrong. The qualifying period for ILR is route-specific. The applicable rules determine the reference date; common possibilities include:

Option A: Date of visa grant — the date the Home Office issued your visa.

Option B: Date of entry to the UK — the date you first entered the UK under that visa.

For a route whose rules count from entry, if your visa was granted on March 1, 2021, but you entered the UK on April 20, 2021, your five-year qualifying period starts on April 20, 2021 — not March 1. For a route with a different rule, the qualifying date may instead use the grant date or another route-specific date.

This means your 28-day window opens on March 23, 2026, and you cannot submit before that date — even though the grant date might suggest an earlier timeline.

For Global Talent, use the date of entry for the 3-year Talent and 5-year Promise periods. UK Ancestry and other routes have their own route-specific rules, so always check the applicable guidance.

If You Changed Visa Category

If you've held multiple visa types during your qualifying period — for example, a student visa followed by a Graduate visa followed by a Skilled Worker visa — the question is whether the time on the earlier visas counts toward the ILR qualifying period.

Under the 2026 framework, Skilled Worker standard settlement is a 10-year qualifying period; a specified high-earner cohort may reduce it to 5 years. Time on student or Graduate leave should not be assumed to satisfy the Skilled Worker route's qualifying-period rules.

For the 10-year Long Residence route, time on almost any lawful leave counts — including student, work, and family visas — provided there were no gaps in lawful status.

This is why some applicants hold a Skilled Worker visa but apply for ILR under the Long Residence route: they have 10 years of total lawful residence across multiple categories, even though their Skilled Worker clock hasn't yet reached its applicable qualifying period.

The Earned Settlement Complexity

The 2026 reforms introduce a further layer of timing complexity for Skilled Worker applicants through the "Earned Settlement" framework. Under the standard rules:

• High earners (£50,270 or more for the 3 years preceding the application) can apply at year 5 even though the baseline for non-accelerated routes is now 10 years
• Very high earners (£125,140 or more) can apply at year 3
• Standard earners without an accelerator apply at year 10

Your applicable qualifying period depends on the route, cohort, and qualifying factors. For Skilled Worker applicants, check the baseline and any eligible reduction under the applicable framework; the April 2024 and July 2025 dates also affect salary cohorts, but do not by themselves determine the qualifying period.

Calculating Your Earliest Application Date: Step by Step

1. Identify your route (Skilled Worker, Long Residence, Partner, etc.)
2. Find the qualifying period length for your route (3, 5, 10, 15, or 20 years, depending on route and qualifying factors)
3. Apply the route-specific rule for the reference date (grant, entry, or another specified date)
4. Calculate the exact date you complete the qualifying period
5. Count back 28 days from that date — that is your earliest application date

For example:

Why You Shouldn't Wait Until the Last Day

Gathering documents takes time. The employer letter, bank statements, P60s, and travel history log all need to be current and accurate at the point of submission. If you calculate your earliest date and then immediately start collecting documents, you'll likely be ready 2–4 weeks later anyway.

The 28-day window gives you a useful runway. Use it to submit when your documents are complete and verified, not at the earliest possible moment. Processing usually starts after the required biometrics or identity-verification step, not simply when the form is submitted — submitting on March 13 versus March 30 has no meaningful impact on when you receive a decision if that step happens at the same time.

Beware of Contradictory Advice Online

The qualifying date calculation generates a disproportionate amount of contradictory advice on forums like r/ukvisa. The reason: the rules changed, and advice from applications submitted before April 2024 may describe a different calculation methodology.

Before the 2026 framework took effect, some routes used different starting-point logic. Advice from someone who applied in 2022 or 2023 may not apply to your situation. Always base your calculation on current Home Office guidance for your specific route.

If you genuinely aren't sure which date your qualifying period starts from — particularly if you had an unusual entry (e.g., you entered on a visitor visa and switched, or your first entry was under a different route) — getting a one-off professional opinion on this single question is worth the cost. A £150 advice session to confirm your qualifying date is cheap insurance against a £3,226 invalid application.

The Relationship Between Application Date and Processing Time

Submitting your application on the earliest possible date doesn't mean you'll receive your ILR decision quickly. Processing starts after you complete the required biometrics or identity-verification step. The application submission and that step are separate.

For Skilled Worker applications, standard processing is usually within 6 months. Partner and Long Residence timing varies by case. Priority service is 5 working days and super priority is next working day where available, subject to route and service availability. So if you submit on day one of the 28-day window but cannot complete the required biometrics or identity-verification step for three weeks, the decision clock may not have started.

Complete the required biometrics or identity-verification step as soon as your application is submitted. In busy periods (spring and autumn tend to be peak application seasons), UKVCAS appointments can fill up quickly, particularly for standard slots at central London service points.

What the Guide Covers

The UK ILR Settlement Guide includes a qualifying date calculator tool that takes your visa route, relevant grant or entry dates, and qualifying factors as inputs and outputs your earliest application date and recommended submission window — so you know exactly when your 28-day window opens and can plan your document preparation accordingly.
