ILR 10-Year Route: Long Residence Requirements and How It Works

The 10-year Long Residence route to ILR is one of the most flexible pathways available — it doesn't require a specific visa type, a job, or a salary threshold. If you've spent 10 continuous years in the UK on valid leave, you may qualify regardless of which visa categories you held during that time.

But this flexibility comes with the most demanding evidential requirements in the settlement system. Proving a decade of continuous lawful residence is a document-heavy process with no margin for gaps.

Who the 10-Year Route Is For

The Long Residence route — applied for on form SET(LR) — serves applicants who don't qualify under a standard five-year route or who have accumulated ten years through a mixture of visa categories.

Typical applicants include:

• People who spent years on student visas, then switched to work visas, and want to use the entire period
• Individuals who were on routes that don't have a direct five-year settlement track
• Former family visa holders whose relationship broke down before the five-year point
• Applicants who held multiple short-term visas that individually don't lead to settlement
• Workers in the UK on routes that were later closed or changed

The route also attracts applicants who technically qualify for a shorter-route ILR but prefer the Long Residence path because it carries different evidentiary requirements around salary — there is no salary threshold for Long Residence ILR.

The Lawful Residence Requirement

Every single day of the 10-year period must be covered by valid leave. This means no overstays, no gaps between visa expiry and new visa grant, and no time spent on expired leave. Even a single day of unlawful presence during the qualifying period can break the continuous residence chain.

Section 3C leave is an important exception: if you submitted an in-time application that is still pending, your previous visa conditions are automatically extended under Section 3C leave. Time spent under 3C leave counts toward the 10-year qualifying period, provided the application is eventually granted.

A key change introduced in 2026 is the elimination of the "historical period" rule. You can no longer use a 10-year period that ended years ago. The qualifying period must be the 10 years immediately preceding your application date.

The Hybrid Absence Rule

The absence calculation for Long Residence ILR is more complex than for five-year routes because of the April 11, 2024 transition date.

For the period before April 11, 2024: the old rules apply — no single absence may exceed 184 days, and total absences across the period must not exceed 548 days.

For the period from April 11, 2024 onwards: the new rolling 180-day rule applies — you must not be absent for more than 180 days in any rolling 12-month window.

If your 10-year qualifying period straddles this date (which it will for anyone applying between 2024 and 2034), you need to run both calculations separately. It's not sufficient to pass one and assume the other is fine.

This hybrid calculation is where most Long Residence applications run into difficulty. The 548-day total cap under the old rules is often well-managed, but the rolling 180-day test applied to the post-2024 portion catches applicants who took long trips abroad in 2024 or 2025 without realising the new standard had taken effect.

Building Your Residence Evidence File

Unlike the Skilled Worker route, where employment records do most of the evidential work, Long Residence applicants must independently prove they were physically present in the UK across the entire decade. Employment records alone don't prove residence; they prove employment, which is different.

The Home Office expects a chronological evidential trail:

Passports — every passport held in the 10-year period, including all data pages. If you renewed your passport during this time, you need both. If a passport was lost or stolen, document that through a police report or new passport application record.

Annual address evidence — at least one piece of address correspondence per year, for each year of the decade. Tenancy agreements, mortgage statements, council tax bills, and bank statements all work. Utility bills work but are slightly less valued than financial correspondence. Gaps in address evidence require written explanation.

Annual employment or study evidence — P60s, letters from employers confirming dates of employment, or university letters confirming study periods. One per year is the minimum; two is safer.

Absence log — a complete record of every departure from the UK and every return, covering all 10 years, with dates, destinations, and reasons for travel. This must reconcile with your passport stamps and with Border Force records.

All visa grants and decision letters — every ILR, extension, and leave-to-remain document from the 10-year period. This demonstrates that every day was covered by lawful leave.

If you have a Subject Access Request (SAR) from the Home Office with your UK Border Force travel history, include it. It's not mandatory, but it shows transparency and often eliminates caseworker doubt.

What Doesn't Count

Time spent outside the UK doesn't pause the clock — it just has to stay within the absence limits. What does interrupt the qualifying period is any period of unlawful presence: overstaying a visa, remaining in the UK after a refusal without Section 3C cover, or entering without leave.

If you've had any immigration compliance issues during the 10 years — even minor ones you resolved at the time — document them carefully. An unexplained gap in your lawful leave history will invite scrutiny.

The Missing Form Question: SET(LR)

Long Residence applicants use form SET(LR), not SET(O) or SET(M). Filing the wrong form can result in the application being treated as invalid, with no refund of the fee. The form is submitted online through the UKVI system.

Preparing for the Application

Most immigration solicitors recommend starting your document-gathering process 18–24 months before your application date for a Long Residence case. The volume of historical records required — employment letters, tenancy agreements, and utility bills stretching back a decade — often involves contacting former landlords, employers, and HMRC for replacement copies of documents you no longer have.

Don't leave document-gathering until the 28-day window before your qualifying date. By that point, there's no time to obtain replacement records or resolve discrepancies.
