BNO after 5 years applies for permanent residency: How to count leaving the country for 180 days, how many years of materials to prepare

Received another Excel file.

The entry and exit records were densely listed over three pages, with the highlighted lines totaling 187 days. The person hadn't slept for three nights, and his first words were, "Are we going to recount the five years again?" I checked with a calculator, and it was actually 179 days. The extra 8 days were all due to him counting the day of departure and the day of returning to the UK as "not in the UK."

This kind of mistake in counting days happens several times a month. BN(O), taking this step after five years, most of the obstacles are not about qualifications, but about misunderstanding the rules — including things that shouldn't be counted and missing things that should be.

Home Office The "Continuous residence" guidance for the visa officer is very explicit: only days when you are away from the UK all day count as absence. The official example is leaving on Monday morning at 5 o'clock and returning on Wednesday evening at 10 o'clock, which counts as 1 day. Your air ticket itineraries show three days, but according to the rules, it's only one day. A family visiting relatives in Hong Kong four times a year can save more than ten days just by this rule.

Permanent residency clause, one sentence at a time: how exactly are these 5 years counted?

BN(O) The permanent residency requirements are set out in Appendix Hong Kong British National (Overseas), and the accompanying "Hong Kong British National (Overseas) route" guidance was last updated on 8 April 2026, version 14.0. Breaking down the key sentence, it actually consists of four independent conditions stacked together; if any one is not met, the other three, no matter how good, are useless.

"Continuous 5 years" — starting from which day?

It counts the time with a valid visa allowing you to reside in the UK, not the date when you first arrived in the UK. If you came for a two-week tourist visa in 2021, those two weeks do not count; the waiting period before the BN(O) visa is approved also does not count. Look at the start date of your eVisa or old BRP visa, that is the starting point.

" In the UK " - 180 days is rolling

No more than 180 days may be spent outside the UK within any 12-month period. The most common pitfall is the word "any": it's not divided by the visa year or the calendar year, but each sliding 12-month window from the application date must be considered individually. From August 2023 to March 2024, returning to Hong Kong continuously to care for family members spanned two "visa years" and appeared to be within limits, but if in any 12-month period that crosses a year, the total days spent outside the UK exceed 180, the five-year requirement will be broken. Appendix Continuous Residence provides a few exceptions (e.g., employed by a UK employer on assignment, significant humanitarian reasons), but they require supporting evidence; it's not enough to just write "there were family matters." Not even one day over is allowed; I've seen too many people only read this carefully for the first time in the refusal letter.

"Or other paths to permanent residency" — during the years of study, don't assume it can be counted by default.

The provision allows the accumulation of BN(O) visa and "another route to settlement". The version circulating in circles is often simplified to "as long as you are legally in the UK, it can all count", and children who have studied two years of master's plus PSW are also added in. This is wrong: the Student and Graduate routes do not lead to ILR by themselves, therefore they are not considered as "route which leads to settlement" mentioned in the provision, and cannot be counted towards five years.

"The last license must be BN(O)"

It's fine to switch to a work visa in the middle, but at the moment you apply for settlement, you must have an active BN(O) pathway visa. If your company lays you off during the work visa period and you want to quickly submit the application using five years, this will directly reject your application. Similarly, the person must apply while in the UK.

Five years is just a ticket to enter. You also need to pass Life in the UK Test, have English at B1 or higher (exemption applies for those under 18, over 65, or with qualifying physical or mental conditions), and pass the suitability check. From April 8, 2026, the settlement application fee is £3,226 per person, and no additional IHS will be charged in the ILR phase.

I will definitely check three things before sending it.

First, divide the five years into five segments, each segment must have traces of people's lives. Leases, council tax, utility bills, bank statements, employer or school letters, GP registration records, evenly spread across each year. The most common material issue is not "absence", but rather everything piled up in the last 18 months - a large part of the second and third years are empty, leaving the visa officer to guess on their own.

Second, recount the days of departure, using the passport stamp, flight ticket and eVisa record for verification, rather than relying on memory. Remember the full-day rule: the day you leave and the day you return are both counted as days in the UK.

Third, the judgment I want to say the most. Those who can afford five years within 2026, don't delay until next year to apply.

The reason is administrative. It has already been clearly stated in the "A Fairer Pathway to Settlement" released by the government on November 20, 2025, that BN(O) holders retain their original five-year pathway through "automatic relief of five years," and there is no ambiguity about this. However, the public consultation following that document was not closed until February 12, 2026, and more than 200,000 responses were received. The accompanying Statement of Changes has not yet been submitted to Parliament, and the official statement is that the relevant changes may fall in autumn this year. Before the rule text is finalized, how transitional provisions will be connected, and whether other requirements during the settlement phase will be adjusted simultaneously, no one can guarantee for you. Those who have met the conditions but are being held back from submitting are risking a definite qualification for a document that has not yet been written. This is my judgment; you may disagree, but please first make sure you have accurately filled out your immigration form.

After the application is submitted, the standard processing time is usually within six months. During this period, your passport will be submitted or you may need to cooperate with identity verification. If you have travel plans, make arrangements in advance. During the processing period, your original permit is protected, so don't get nervous because of the expiration date on the visa card.

For the past five years, the first four and a half years were about living well, and the last half year was about translating life into evidence that Home Office recognizes. Both things are done, the rest is just waiting for a letter.
