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

Received another Excel file.

The entry and exit records were densely listed over 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 went through it 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 rather because you misread the rules — including what shouldn't be counted and excluding what should be.

Home Office The "Continuous residence" guidance for the visa officer is very straightforward: only days when you are away from the UK all day count as absence. The official example is leaving on Monday morning at 5 AM and returning on Wednesday evening at 10 PM, 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 are these 5 years counted?

BN(O) The permanent residency requirements for the route are set out in Appendix Hong Kong British National (Overseas). Home Office 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" — starting 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 your BN(O) visa also does not count. Look at the start date of your permission on your eVisa or old BRP, that is the starting point.

" In the UK " — 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 based on the visa year or the calendar year, but rather on each sliding 12-month window starting from the application date, which must be individually verified. From August 2023 to March 2024, returning to Hong Kong continuously to take care of 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 exceeded 180, the five-year requirement would be broken there. Appendix Continuous Residence provides a few exceptions (e.g., employed by a UK employer on assignment, significant humanitarian reasons), but they require evidence; you can't just say "there were family matters" and get through. Not even one day over is allowed. I've seen too many people only read this carefully for the first time in a refusal letter.

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

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 all counts", so the child's two years of master's plus PSW are also added in. This is wrong: the Student and Graduate routes themselves do not lead to ILR, therefore they are not considered "route which leads to settlement" mentioned in the provision, and cannot be counted towards five years.

"The last license must be BN(O)"

There is no problem with switching to a work visa in the middle, but at the moment you apply for permanent residency, the valid visa you hold must be under the BN(O) route. 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 level or above (exempt for those under 18, over 65 years old, and those with qualifying physical or mental conditions), and pass the suitability review. Starting 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, split the five years into five segments, each segment must have traces of people living there. 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 "none", but everything piled up in the last 18 months - a large part of the second and third years are empty, and visa officers can only guess for themselves.

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 have enough 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 "A Fairer Pathway to Settlement" released by the government on November 20, 2025, that BN(O) holders retain their original five-year pathway in the "automatic five-year relief" manner, and there is no ambiguity about this. However, the public consultation following that document was not due until February 12, 2026, and more than 200,000 responses were received. The accompanying Statement of Changes has not yet been submitted to the parliament to date, and the official statement is that the relevant changes may fall in the autumn of this year. Before the rule text is finalized, how the 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 applying are risking a definite qualification for an un-written document. This is my judgment, you may disagree, but please first make sure you have counted your own 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 arrangements 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.
