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 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 qualification period. Three months earlier, no one dared to give an answer - on April 11, 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 from 2024, regardless of how you count, there will always be years where 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: only the period before April 11, 2024 matters

Appendix Continuous Residence's CR 2.2A is very specific: For the period of eligibility in the long residence application prior to April 11, 2024, each 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 assessed based on any rolling 12-month period not exceeding 180 days. The two sets of limits apply to separate periods, without being combined or overlapping. Home Office The current "Long residence" case processing guidance (August 3, 2026 edition) states that for a ten-year period crossing April 11, 2024, there is no total of 548 days for the entire ten years.

Calculate with today's date. Submit in October 2026, count back the eligibility period to October 2016, where approximately seven and a half years fall under the old criteria (looking at a single trip of 184 days and the total during this period), the most recent two and a half years under the 180-day rolling window. Each segment can be qualified separately.

My judgment is that for those who follow the ten-year rule, the exit risk should be managed based on the duration of each single trip, rather than focusing on the total days within ten years. Splitting a long visit into two parts and squeezing them into different 12-month windows is a valid arrangement under the current rules; delaying the trip in order to meet the "total ten-year days shouldn't exceed 548" target uses an old guideline that no longer applies to people submitting applications now.

Which situations can really make ten years zero?

Once continuous residence is interrupted, the effect is not a pause, but the line that is counted backward breaks at the interruption point: Appendix Continuous Residence calculation method counts back decades from the application date. Time before the break point cannot be counted anymore, so it has to be accumulated again from after the break point. The following are the real cases that would cause this consequence.

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

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

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

This is the most common scenario in the past ten years: 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: periods without permission will break continuous residence; however, there is a specific exception for long-term residency applications - if the person holds a valid permission when leaving and returns to the UK with a valid permission (same route or another route), and the absence does not exceed the CR limit, this gap will not constitute a break.

Exceptions apply, but this does not mean that this period counts toward 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 pushed back. The easy-to-miss part is that the five-year work permit route does not have this permanent resident-specific exception. The same period of absence may lead to different conclusions on the two routes.

To confirm which side you are on, the required materials are simple: list every entry and exit over the past ten years in three columns (departure date, return date to the UK, and the validity dates of the visa held at that time). It will be immediately obvious where any gaps occur and whether the visa was still valid on the day of departure. Remember to count the two cross-year trips 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 three or four times, and the breakpoints are often buried in the journey that no one mentions anymore in the third or fourth year. Making out that three-column chart is more useful than remembering any number of days.
