How is the 10-year permanent residency gap calculated? Which departures will reset the 10 years?

In July 2024, the Home Department added a clarification to the Long Residence case guidance, narrowing the old figure of 548 days into a very limited scope: it only applies to the period before April 11, 2024, within the ten-year qualifying period. Three months earlier, no one dared to give an answer - on April 11, 2024, Appendix Long Residence officially replaced paragraph 276B, changing the exit limit from "no more than 184 days per trip and no more than 548 days in total over ten years" to "no more than 180 days in any rolling 12-month period." Going back decades from 2024, no matter how you count, there will always be years when the old rules were still valid.

So, the question "Will there be a gap in ten years?" should be answered by looking at different time periods.

Is 548 days still valid: just the period before April 11, 2024.

Appendix Continuous Residence's CR 2.2A is very specific: For the period of eligibility in the long-term residency application prior to April 11, 2024, each single absence must not exceed 184 days, and the total for this period must not exceed 548 days; absences on April 11, 2024, and thereafter will be counted based on any rolling 12-month period not exceeding 180 days. The two sets of limits each apply to their respective periods, without being combined or overlapping. Home Office The current "Long residence" case handling guidelines (August 3, 2026 version) state that for a ten-year period crossing April 11, 2024, there is no total of 548 days for the entire ten years.

Calculate again with today's date. Submit in October 2026, the qualification period is counted back to October 2016, of which approximately 7.5 years fall under the old criteria (looking at a single trip of 184 days and the total during this period), the most recent 2.5 years are calculated using an 180-day rolling window. Each segment can meet the requirements separately.

My judgment is that people following the ten-year line should have their outbound risks managed based on the duration of each trip, rather than focusing on the total days within ten years. Splitting a long visit into two segments and fitting them into different 12-month windows is a valid arrangement under the current rules; delaying the trip in order to meet the "total ten years shouldn't exceed 548 days" target uses an old guideline that no longer applies to those submitting applications now.

Which situations can really make ten years count as zero?

Once continuous residence is interrupted, the effect is not a pause, but the line of counting back is broken at the interruption point: Appendix Continuous Residence calculation method counts back decades from the application date. Time before the interruption point cannot be counted again, so it needs to be accumulated again from after the interruption point. The following are the types that will really cause this consequence.

LR 11.2 clearly excludes immigration bail, temporary entry, temporary release, and the duration of overstaying from the ten years. The fifth row in the table is most prone to issues because the parties usually still live in the UK and are still working, and do not realize they have already crossed that line.

In other words, as long as the absence in each rolling 12-month period is within 180 days, leaving for five months in a year does not constitute a gap. The number of days itself does not become a problem just because "it seems too long."

Return to the country before the visa expires to wait for a new visa, how is this gap period calculated?

This is the most common scenario in the past decade: students' visas are about to expire, they return home first, and then fly back a few weeks or months later with a new visa.

Appendix Continuous Residence rules state that periods without permission will break continuous residence; however, there is a specific exception for long residency applications - if the person was holding a permit when leaving and holds a valid permit upon returning to the UK (by the same route or another route), and the absence does not exceed the CR limit, this gap will not constitute a break.

Exceptions apply, which do not mean that this period can be counted towards the ten years. LR 11.1 requires that each day of the qualifying period falls within the validity of the permit (excluding visitors, Short-term Student language courses, and seasonal workers). The days when the person is outside the country and does not have a permit are neither considered as gaps nor as legal residence within the ten years, resulting in the expiry date being extended. The easy-to-miss part is that the five-year work permit route does not have this special exception for long-term residents. The same period of absence may lead to different conclusions on the two routes.

The materials needed to confirm which side you are on are very simple: list every entry and exit over the past ten years in three columns (departure date, return date to the UK, and the validity period of the visa held at that time). It will be immediately clear where the gaps are and whether the visa was still valid on the day of departure. The two trips crossing the year should be counted separately according to the overlapping periods with each window.

The characteristics of the ten-year line are that the time is too long, the route often changes several times, and the breakpoints are often buried in the journey from the third or fourth year, which is never mentioned again. Making out that three-column table is more useful than remembering any number of days.
