What counts as an absence for ILR?

The basic definition: whole days outside the UK

Appendix Continuous Residence of the Immigration Rules is the part that decides whether your time in the UK counts towards indefinite leave to remain. It measures absence in whole days spent outside the United Kingdom. The Home Office’s continuous residence guidance for caseworkers confirms the two edges of every trip:

• The day you leave the UK is not counted as a day of absence.
• The day you return to the UK is not counted as a day of absence.

So a trip that departs on Friday evening and lands back on Monday morning counts as two days of absence (Saturday and Sunday), not four. A same-day return — out in the morning, back at night — counts as zero. This is more generous than the way the Schengen 90/180 rule counts days, where both ends of a trip count, so do not reuse a Schengen tally for an ILR application.

Why you were away does not change whether a day counts. Holidays, business trips, visiting family, working remotely from abroad, medical treatment and study trips are all absences. The reason only matters if you go over the limit and need an absence disregarded (see the exceptions below).

The limit: 180 days in any rolling 12 months

Paragraph CR 3.1 of Appendix Continuous Residence sets the cap: you must not have been outside the UK for more than 180 days in any 12-month period during your qualifying period. Three features of that sentence catch people out:

1. 1It is rolling, not calendar. Every possible 12-month window inside your qualifying period is tested, not just January to December or visa year to visa year. A 100-day trip in November and another 100-day trip the following May sit in the same window.
2. 2It is cumulative. All trips inside a window are added together. Twenty short trips of nine days each breach the cap just as surely as one long one.
3. 3It applies across the whole qualifying period. Five years on Skilled Worker means roughly 1,460 distinct 12-month windows, and each one has to pass.

If any window exceeds 180 days and no exception applies, continuous residence is broken at that point and the clock generally restarts. The mechanics of the rolling window are explained on the ILR 180-day absence rule page and in what a rolling 180-day period means; the consequences for your application date are in when you can apply for ILR.

Absences that can be disregarded

Paragraph CR 3.4 lists the circumstances in which an absence that would otherwise break continuous residence can be disregarded. The caseworker does not ignore the absence automatically — you have to show the reason and support it with evidence — but where it is accepted, the excess days do not count against you. The permitted reasons are:

• Serious or life-threatening illness of the applicant or of a close family member;
• Conflict in the country you were in;
• Natural disaster;
• Travel disruption — the rules give the pandemic and volcanic ash clouds as examples;
• Compelling and compassionate personal reasons that were outside your control.

Some routes go further. Depending on the route, absences for work-related travel, research or study may be treated differently — typically on the talent, research and entrepreneur routes, where time abroad that is part of the work the visa was granted for is addressed specifically. Whether that applies to you depends on the appendix for your own route, so read that appendix alongside Appendix Continuous Residence rather than assuming a colleague’s treatment carries over.

What does not qualify

Ordinary annual leave, a long visit home, a sabbatical, remote working from another country by choice, and being "asked" by an employer to spend months abroad without any of the CR 3.4 circumstances are not permitted reasons. Nor is not knowing about the rule.

Ireland, the Isle of Man and the Channel Islands

The Common Travel Area lets you move between the UK, Ireland, the Isle of Man and the Channel Islands without routine passport control, and you are allowed to travel there while an ILR application is pending. That does not make those places part of the United Kingdom. For Appendix Continuous Residence, time spent in Ireland or the Crown Dependencies is time outside the UK and counts towards your 180 days unless the rules for your route say otherwise. Because there is often no stamp or eGate record for these journeys, they are also the easiest absences to forget when you compile your list — check the GOV.UK guidance for your route and include them.

Proving your absences

The application form asks you to list every absence during the qualifying period with dates and reasons. Caseworkers check this against Home Office travel records where they exist, and will write out if the two do not reconcile — the most common avoidable delay on an ILR application.

• Passport stamps are no longer reliable. eGates do not stamp on entry to the UK, and many other countries have stopped stamping too. A passport alone will not reconstruct your travel history.
• A day-by-day log is what caseworkers want — departure date, return date, destination, reason — supported by boarding passes, e-tickets, hotel bookings or employer letters for trips that need a permitted reason.
• Do it before you apply, not after a request. An accurate list at submission avoids the pause while you reconstruct it, and lets you spot a breaching window while you can still do something about it.

Bounded records border crossings automatically as you travel and exports the list, so the log exists before the form asks for it. To check the totals, the free UK ILR absence calculator applies the departure-and-return-day convention, tests every rolling 12-month window against 180 days and shows your earliest application date. The wider process — tests, fees, documents — is covered in the ILR guide and the document checklist.

Worked examples

• Weekend in Paris, Friday to Monday. Two days of absence (Saturday, Sunday).
• Three-week holiday, out 1 August, back 22 August. Twenty days of absence (2 to 21 August inclusive).
• Six months caring for a seriously ill parent abroad, plus 30 days of earlier holidays in the same 12 months. Around 210 days in one window — over the cap — but the caring absence falls under CR 3.4 if evidenced, so it can be disregarded.
• Working from Dublin for three months. Roughly 90 days of absence: Ireland counts as outside the UK, and remote working by choice is not a permitted reason.
