The 180-day absence rule means that for most routes to indefinite leave to remain (ILR), you must not spend more than 180 days outside the UK in any rolling 12-month period during your qualifying period. It is tested across every 12-month window, not by calendar or visa year. If you exceed it without a permitted reason, your continuous residence can be broken, and the qualifying period may have to start again.
Most applicants know the number. Fewer know how the window moves, what counts as a day away, or which absences the Home Office will disregard. This guide covers all three. The wider settlement process is explained on our indefinite leave to remain page, and the official rules are in Appendix Continuous Residence on GOV.UK.
Which routes the rule applies to
The rule sits in Appendix Continuous Residence, which covers most work and talent routes that lead to settlement, and their dependants. Family routes work differently, so check which category you are in.
| Route | Continuous residence test |
|---|---|
| Skilled Worker | 180 days in any rolling 12 months |
| Global Talent | 180 days in any rolling 12 months |
| Innovator Founder | 180 days in any rolling 12 months |
| UK Ancestry | 180 days in any rolling 12 months |
| Hong Kong BN(O) | 180 days in any rolling 12 months |
| Ten year long residence | 180 days in any rolling 12 months for absences from 11 April 2024, with older limits for earlier absences |
| Partner routes under Appendix Settlement Family Life | Assessed under different rules, which can allow some longer absences where family life in the UK continues |
The Start-up visa closed to new applicants in 2023, so the Innovator Founder visa is the founder route now relevant to settlement. Some temporary routes, such as the UK Expansion Worker visa, do not lead to settlement at all, and neither does the child student route. Time spent on those routes is a separate question from the rule in this guide.
How the rolling window works
The Home Office does not look at your visa years or calendar years. It looks at every possible 12-month period inside your qualifying period and asks whether your days outside the UK in that period exceeded 180. One bad window is enough.
Here is a worked example. A Skilled Worker takes these trips, none of which looks excessive on its own.
| Trip | Days away |
|---|---|
| March 2025 | 20 |
| October 2025 | 50 |
| December 2025 | 45 |
| January 2026 | 40 |
| March 2026 | 25 |
| June 2026 | 30 |
Her calendar year totals are 115 days for 2025 and 95 days for 2026, both comfortably under 180. But in the window from 1 October 2025 to 30 September 2026, she was away for 190 days. That breaks the limit, even though no calendar year does. This is the trap that catches people who check their totals once a year.
Because the test covers the whole qualifying period, you cannot fix a breach by choosing a different application date. Before January 2018 the test counted back from the date of application, which gave some flexibility. That flexibility no longer exists.
What counts as a day outside the UK
Count every day you are outside the UK, whatever the reason. This includes holidays, family visits and business trips. Work travel counts even where your employer required it, subject to the narrow exceptions below.
There are a few points people miss:
- The gap before you arrive. Practitioners note that the period between your entry clearance being granted and your first arrival in the UK can count as time outside the UK, so a late arrival can use up part of your first-year allowance.
- Day counting. Home Office guidance sets out how departure and return days are treated. Do not assume they are free. Keep exact travel dates and check the current guidance before you apply.
- Remote working abroad. Working from another country is still time outside the UK.
- Time stuck abroad. Being unable to return because of illness or travel disruption still counts unless a permitted absence applies.
Permitted absences
Some absences are disregarded when you calculate your days. These are the permitted absences in Appendix Continuous Residence, and you need evidence to rely on them.
| Permitted absence | What it covers | Evidence you will need |
|---|---|---|
| Compelling and compassionate circumstances | For example, the life-threatening illness of you or a close family member, or the death of a close family member | Medical letters, death certificates, travel records |
| Travel disruption | Natural disasters, military conflict or a pandemic that stopped you returning | Proof of the disruption and your attempts to return |
| Approved research | Certain Skilled Worker or Global Talent research, limited to specific occupation groups and approved by the sponsor | Sponsor letter and role evidence |
| Covid Exceptional Assurance | Where it was granted for a covered period | The Home Office confirmation, usually by email |
The exceptions are narrower than people hope. A long holiday, a family event that is not an emergency or a business trip your employer asked for usually does not qualify. Where a personal circumstance is genuinely compelling, the evidence should explain it plainly, with dates.
If you have gone over 180 days
First, check the arithmetic, including the pre-arrival gap, because calculation errors are common. Then look at whether any absence is permitted, and gather evidence for it.
If a breach stands, you have a few options depending on your case:
- Rely on a permitted absence with strong evidence and a clear explanation.
- Ask for discretion where the circumstances are compelling. Discretion exists but is narrow, and larger breaches are harder to excuse than minor ones.
- Wait and apply later once the qualifying period has restarted, if that is realistic.
- Consider another route, such as long residence, if your overall history supports it.
A refusal on continuous residence grounds can be challenged in some cases, so read our guide on UK visa refusals and our page on appeals and judicial review if you receive one. Do not submit an application you know breaches the rule without a clear plan, because a refusal creates a record and costs the fee, which is currently £3,226.
Rules people confuse with the 180-day rule
Three other absence rules are often mixed up with it.
| Rule | What it says | Where it applies |
|---|---|---|
| 180 days in any rolling 12 months | The ILR continuous residence test | Most work and talent routes |
| 450 days in five years, and 90 days in the final 12 months | The naturalisation absence limits | British citizenship applications |
| Two years continuously outside the UK | ILR can lapse if you stay away this long | After ILR is granted |
The citizenship limits are stricter and counted differently, so passing the ILR test does not mean you pass the citizenship test. Our guides to British citizenship and days outside the UK and British citizenship after ILR explain how, and our British citizenship page covers the application itself.
What the earned settlement proposals mean for absences
The government has proposed an earned settlement model that would extend the standard qualifying period from five years to ten for most migrants. As far as I could confirm in mid-October 2026, that has not been brought into the Immigration Rules, and the current five year rules still apply. Our guide to the proposed earned settlement reforms tracks the position.
One change is already in the rules but not yet in force. The March 2026 Statement of Changes raised the English language requirement for settlement on several routes to CEFR level B2, from 26 March 2027. If your application date is near that date, check which level applies to you.
Whatever happens to the qualifying period, absence limits are likely to matter just as much, because a longer qualifying period gives you more windows to breach. Keep your records from day one.
How to track your absences
- List every departure and return from your passport, e-tickets, boarding passes and the Home Office travel history.
- Record the exact dates in a spreadsheet, one row per trip.
- Test every rolling 12-month window, not just calendar or visa years.
- Include the pre-arrival gap if you were granted entry clearance before you travelled.
- Note the reason for each trip, and keep evidence for any you may argue are permitted.
- Check again before you book any long trip in your final two years.
Our guide to UK immigration timelines helps you plan the application date around your travel. You can usually apply up to 28 days before your qualifying period ends, which gives a small amount of flexibility on timing but does not cure a breach.
Common mistakes
| Mistake | Why it hurts | Better approach |
|---|---|---|
| Checking calendar year totals only | Misses a bad rolling window | Test every 12-month window |
| Forgetting the pre-arrival gap | Understates your first-year absence | Count from the grant date |
| Assuming employer-required travel is excluded | It still counts | Treat work trips as absences |
| Relying on memory | Passport stamps are incomplete | Keep dated records as you go |
| Applying despite a known breach | Wastes the fee and creates a refusal | Get advice first |
| Mixing up ILR and citizenship rules | Passes one test, fails the other | Check both before you plan |
Dependants and family members
Dependants of work route holders generally follow the same absence limits as the main applicant, though their own qualifying periods can differ if they arrived later. Our guide to Skilled Worker dependants explains how timelines work for families. Partners settling through a family route are assessed under different rules, as our pages on the spouse visa and the unmarried partner visa explain.
Frequently asked questions
What is the ILR 180-day absence rule?
You must not spend more than 180 days outside the UK in any rolling 12-month period during your qualifying period. It applies to most work and talent routes and their dependants.
Is it 180 days per year or in total?
It is 180 days in any rolling 12-month window, and there is no separate overall cap for the whole five years. But every window is checked, so one bad window is enough to cause a breach.
Do business trips count?
Yes. Time outside the UK counts even where your employer required the travel, unless a specific permitted exception applies.
What happens if I exceed 180 days?
Your continuous residence may be broken, and the qualifying period may have to restart. You may be able to rely on a permitted absence or, in narrow cases, ask for discretion.
Does the rule apply to British citizenship?
No, citizenship has its own, stricter limits of 450 days in five years and 90 days in the final 12 months. See our guide to days outside the UK for citizenship.
Can ILR be lost by staying abroad?
Yes. ILR can lapse if you spend more than two continuous years outside the UK, which is a separate rule from the 180-day test.
Get your absences checked before you apply
A single miscounted trip can cost you years. If you are close to the limit, have a complicated travel history or have already gone over, our immigration solicitors in London can check your calculation, identify any permitted absences and advise on the safest way to apply.
