The 180-day absence rule is the single biggest source of anxiety for people on the ILR journey. Most articles explain it badly. This one explains it with real numbers.
To qualify for ILR, you must not spend more than 180 days outside the UK in any rolling 12-month period during your qualifying years.
Two words in that sentence matter: rolling and any.
The window is not January to December. It is not your visa anniversary to anniversary. It is every possible 12-month window across your entire qualifying period. The Home Office checks all of them.
Say you left the UK on 1 June 2023 and returned on 1 December 2023. That is 183 days outside the UK.
Now the Home Office looks at every 12-month window that contains that trip:
| 12-month window | Days absent | Result |
|---|---|---|
| 1 June 2023 – 31 May 2024 | 183 days | Over limit |
| 2 May 2023 – 1 May 2024 | 183 days | Over limit |
| 1 December 2022 – 30 November 2023 | 183 days | Over limit |
A single long trip can fail multiple windows simultaneously. That is why one bad trip matters far more than people expect.
The Home Office counts the number of days you were physically outside the UK. Your departure day and return day are generally not counted as absences. But this can vary. When in doubt, count them and stay safely under 180.
Going over 180 days in a rolling window does not automatically end your ILR eligibility. The Home Office has discretion. But you will need to explain it.
If you exceeded 180 days, do this before you apply:
Applications with excess absences are not automatically refused. But they take longer and receive more scrutiny. Do not apply without a clear explanation ready.
If your absences happened between 23 March 2020 and 18 March 2022, the Home Office may treat them as exceptional circumstances due to COVID-19 travel restrictions.
This is discretionary, not automatic. It does not mean absences in that period are ignored. It means you can ask the Home Office to use their judgement.
If you have COVID-period absences that pushed you over 180 days, include a covering letter explaining:
Settle Easy UK shows both your standard absence total and your COVID-adjusted total, so you can see exactly where you stand before you apply.
A spreadsheet can record trips, but it cannot check rolling windows. To be safe, you need to check every possible 12-month window across 5 years. That is hundreds of windows.
Settle Easy UK's absence tracker does this automatically. Log your trips and it shows you your worst window, your total days, and whether you are in the safe, warning, or danger zone.
"I only took 150 days off in 2023" is not the same as passing the 180-day test. You need to check every rolling window, not just each January-to-December period.
A long weekend in Europe, a quick visit home: they all count. Log every trip, no matter how short.
If you stopped over in another country on the way somewhere, those days count as time outside the UK.
Log your trips once. Settle Easy UK checks every rolling window automatically and tells you if any period is at risk.
