During your ILR qualifying period, you must not spend more than 180 days outside the UK in any rolling 12-month window. Exceeding this in any single window breaks your continuous residence — regardless of what your total absences look like across the whole qualifying period. This is one of the most misunderstood aspects of ILR eligibility. For a full overview of all ILR requirements, see our ILR requirements guide, or our ILR service page for how we can help.
What Is Continuous Residence?
Continuous residence is the legal requirement that you have been lawfully present in the UK throughout your qualifying period without a material break. Break it at any point and your qualifying period — and the five or ten years you have been counting down — resets. Three things can break continuous residence:
- Spending more than 180 days outside the UK in any rolling 12-month period
- A single absence of more than six months, even if within the 180-day total
- Being in the UK unlawfully at any point — for example, after a visa expiry and before a renewal
How Absences Are Counted
The Home Office does not look at absences per calendar year. It uses rolling 12-month windows. Every date within your qualifying period is treated as the end-point of a 12-month lookback. If you spent more than 180 days outside the UK in the 12 months ending on any particular date, your continuous residence is broken from the date the limit was first exceeded.
Worked example
| Period | Days abroad | Rolling 12-month window breached? |
|---|---|---|
| Jan–Dec 2022 (calendar year) | 160 days | No (calendar year view) |
| Jul 2022–Jun 2023 (rolling window) | 195 days | Yes — residence broken from approx. Dec 2022 |
In the example above, an applicant counting absences per calendar year would think they are within the limit. But the rolling window that crosses the year boundary shows 195 days — over the limit. The qualifying clock restarts from when the applicant returned to the UK. Counting absences per calendar year is one of the most common errors in ILR applications. Always use rolling 12-month windows.
Circumstances That May Break Continuous Residence
- Single absence over six months — breaks residence even if total absences are under 180 days in that window
- Visa expiry without renewal — any period of overstay, however short, breaks lawful residence
- Deportation or removal — terminates continuous residence from the date of removal
- Curtailment of leave — where the Home Office curtailed your leave during the qualifying period
Home Office Discretion Over Excess Absences
The Home Office has the power to exercise discretion and overlook excess absences in exceptional circumstances. In practice, discretion is applied narrowly. The circumstances most likely to support a discretion argument are serious illness that prevented return to the UK, bereavement requiring extended time abroad, and compulsory overseas posting required by your employer. Voluntary decisions to spend extended time abroad — even for legitimate personal reasons — are unlikely to attract discretion.
There is no right of appeal against a refusal to exercise discretion in the same way there is against a refusal under the Rules. If you are depending on discretion, gather every piece of evidence supporting your circumstances before applying, and take professional advice. See our ILR adviser service for help with borderline cases.
Worked Examples
Example 1 — borderline absences, no discretion needed
An applicant on a Skilled Worker visa took multiple trips between 2021 and 2025. In total across the five years she was abroad for 620 days. In any single rolling 12-month window, the maximum was 178 days. Her continuous residence is intact. She can apply for ILR on the qualifying date.
Example 2 — excess absences, restart required
An applicant on a spouse visa was abroad for 210 days during a rolling 12-month period in 2022. His continuous residence broke when his running total hit 181 days. His qualifying period restarted from his return date. His five-year qualifying date moved from 2024 to 2028.
Example 3 — excess absences with discretion argument
An applicant spent six months and three weeks abroad in 2023 following a serious accident that left her hospitalised overseas. She holds hospital records, consultant letters, and correspondence with her employer. This is the kind of documented, genuinely exceptional circumstance that supports a discretion argument — though it is not guaranteed to succeed.
What to Do If You Have Excess Absences
Do not apply until you understand the position properly. A refusal for excess absences costs you the £3,226 application fee and leaves a refusal on your immigration record. Calculate all your absences using rolling 12-month windows across the full qualifying period. Identify whether any rolling window exceeds 180 days. If it does, identify when continuous residence broke and when your qualifying period would restart. If there are exceptional circumstances, gather documentation before applying.

Frequently Asked Questions
What is the ILR 180 day rule?
The 180-day rule limits the time you can spend outside the UK in any 12-month period during your ILR qualifying period. Exceed 180 days in any rolling 12-month window and your continuous residence is broken from the point the limit was reached. Your qualifying clock then restarts.
How does the Home Office calculate absences?
Using rolling 12-month windows, not calendar years. Every date in your qualifying period is the end-point of a 12-month lookback. This method often produces a different — and worse — result than counting absences per calendar year.
Does the day of departure or arrival count as an absence?
UKVI guidance states that departure and arrival days do not count as days of absence — only complete days spent abroad are counted. Do not rely on this to bring a borderline total within the limit; keep your absences well within 180 days wherever possible.
Can the Home Office exercise discretion over excess absences?
Yes, but narrowly. Discretion is most commonly applied where absences resulted from serious illness, bereavement, or compulsory overseas work. It is not applied consistently. Do not treat it as a reliable fallback — gather all evidence and take advice before applying.
