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 your qualifying anniversary — but applying even one day before that window opens results in an automatic refusal and no refund of the £3,226 application fee.

The calculation sounds simple. It isn't.

How the 28-Day Window Works

Your ILR qualifying period is typically 5 years or 10 years, depending on your route. The 28-day window opens exactly 28 days before the date you complete that qualifying period.

Example for a 5-year Skilled Worker: 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 does not always start on the date your first visa was granted. There are two possible starting points:

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 most Skilled Worker and Partner route applicants, the qualifying period runs from the date of entry to the UK, not the visa grant date. 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.

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.

Some routes have different rules. Global Talent visa holders may count from the date of entry; UK Ancestry holders also count from entry. Always check the specific rules for your route.

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.

For the standard 5-year Skilled Worker route, only time spent on the Skilled Worker (or its predecessor, Tier 2 General) visa counts. Time on a student visa does not carry over, even if it was lawful leave.

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 five years.

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+ for 3 years) can apply at year 5 even though the base line for non-accelerated routes is now 10 years
• Very high earners (£125,140+) can apply at year 3
• Standard earners without an accelerator apply at year 10

If you entered the UK on a Skilled Worker visa after the relevant reform dates, your qualifying period may be 10 years unless you meet a salary accelerator. If you're uncertain which baseline applies to you, check whether your sponsorship date falls before or after the April 2024 and July 2025 reform thresholds.

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 (5 years, 10 years, or accelerated)
3. Determine whether the period runs from your visa grant date or your UK entry 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. The ILR decision clock starts from your biometrics appointment, not your submission date — submitting on March 13 versus March 30 has no meaningful impact on when you receive a decision.

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 begins when you book and attend your biometrics appointment at UKVCAS. The application submission and the biometrics appointment are separate steps.

For standard processing, expect 4–8 weeks from the biometrics appointment. For priority service, 5 working days from biometrics. So if you submit on day one of the 28-day window but can't get a biometrics appointment for three weeks, the decision clock hasn't even started.

Book your biometrics appointment 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, grant date, and entry date 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.
