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

Received another Excel file.

The entry and exit records were densely listed on three pages, with the highlighted lines adding up to 187 days. The person hadn't slept well for three nights, and his first words were, "Are we going to recount the five years again?" I checked with a calculator, and the actual number was 179 days. The extra 8 days were all due to him counting the day of departure and the day of return 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 because you misread the rules — including things that shouldn't be counted and excluding things that should be.

Home Office The "Continuous residence" guidance for the visa officer clearly states that 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 itinerary shows 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 is this 5 years counted?

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

"Continuous 5 years" — from which day?

It counts the time you have lived in the UK with a valid visa along this route, not the date when you first arrived in the UK. If you came for a two-week tourist visit in 2021, those two weeks do not count; the period before the approval of BN(O) also does not count. Check the start date of your permission on eVisa or your old BRP, that is the starting point.

"United Kingdom" - 180 days is rolling

No more than 180 days can 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 take care of family members spanned two "visa years" and seemed fine at first glance. However, if the total time spent outside the UK exceeded 180 days within any 12-month period that crosses the year, the five-year requirement would be broken there. Appendix Continuous Residence provides a few exceptions (e.g., being dispatched by a UK employer, significant humanitarian reasons), but they require supporting evidence; it's not enough to just write "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 okay to switch to a work visa in the middle, but at the moment of applying for settlement, you must have an active BN(O) route visa. If your company lays you off during the work visa period and you want to quickly apply using five years, this will directly reject your application. Similarly, the person must submit the application 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 level or above (exemption applies for those under 18, over 65, and those with qualifying physical or mental conditions), and pass the suitability review. From April 8, 2026, the settlement application fee will be £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, split 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 "lack", but everything piled up in the recent 18 months - a large part of the second and third years are empty, and visa officers can only guess by themselves.

Secondly, recount the days of departure, using the passport stamp, 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 spent in the UK.

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

The reason is administrative. It has already been clearly stated in the government's "A Fairer Pathway to Settlement" released 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, with over 200,000 responses received. The accompanying Statement of Changes has still not been submitted to Parliament to date, 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 in the settlement phase will be adjusted simultaneously, no one can guarantee for you. Those who have already met the conditions but are being held back without submitting are risking a certain qualification for an un-written document. This is my judgment; you may disagree, but please first make sure you have counted your immigration form correctly.

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 sure to arrange them in advance. During the review period, your original permit is protected. Don't get nervous because the expiration date on the visa card comes first.

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