British Citizenship by Marriage

British Citizenship by Marriage: the Three-Year Route in 2026

If you are married to or the civil partner of a British citizen, you do not have to wait as long as everyone else. The three-year route under section 6(2) of the British Nationality Act 1981 is shorter, more generous on absences, and drops one requirement entirely.

It is also widely misunderstood. People assume marriage to a British citizen makes them British, or that it removes the need for settled status. It does neither. What it does is change the timetable — and for many couples that is worth a year or more.

Fees and requirements checked against GOV.UK on 31 August 2026. Home Office rules and fees change frequently — verify before you apply, or ask us to.

Three ways the spouse route differs

Everything else is the same as the standard route. These three differences are the whole advantage:

That last row is the one almost nobody mentions, and it matters. The future intentions requirement — that you intend your principal home to be in the UK — applies to applicants under section 6(1). It does not apply to spouses applying under section 6(2). If your work takes you abroad regularly, or you expect to spend significant time overseas after naturalising, the spouse route removes a question you would otherwise have to answer.

The absence allowance is proportionally more generous too: 270 days across three years is 90 days a year, against 90 days a year on the five-year route. The same, in annual terms — but you reach the finish line two years sooner.

Who qualifies

You can apply on this route if, on the date the Home Office receives your application, all of the following are true:

• You are 18 or over
• You are married to, or the civil partner of, a British citizen
• You hold indefinite leave to remain, settled status or indefinite leave to enter — with no minimum holding period
• You have been in the UK for three years before the date of application
• You were physically in the UK on the day exactly three years before the Home Office receives the application
• You have not been outside the UK for more than 270 days in those three years, nor more than 90 days in the final twelve months
• You are of good character
• You meet the English language requirement at CEFR B1 or above, and have passed the Life in the UK test

Your spouse must be a British citizen — not just settled

This is the most common misunderstanding we see. Your partner must actually hold British citizenship. If they have indefinite leave to remain but have not naturalised, the three-year route is not open to you: you fall back on the standard five-year route with its twelve-month wait.

Where both partners are eligible, there is sometimes a sequencing argument for your spouse naturalising first, which then opens the shorter route to you. Whether that is faster overall depends on your own timeline, and it is worth modelling before either of you files.

The marriage must be valid, and it must still exist

The Home Office needs a marriage or civil partnership recognised under UK law. Religious ceremonies not registered under the law of the country where they took place are a recurring problem, as are divorces from earlier marriages that were never properly finalised.

You must still be married on the date of application. There is no requirement to be living together at that moment, and no minimum length of marriage — but a marriage that has broken down, or one the Home Office considers was entered into for immigration purposes, raises issues under good character rather than under the relationship rules.

Counting your absences

The 270-day limit is the requirement that most often trips people on this route, precisely because it is tighter in absolute terms than the 450 days allowed over five years.

Count every trip. Weekend breaks, family visits, work travel — all of it. If you are close to the limit, waiting a few months is almost always cheaper than testing the Home Office's discretion to overlook excess absences, which exists but is exercised sparingly and is not something to plan around.

Check the final twelve months separately. It is entirely possible to be comfortably inside 270 days over three years while breaching the 90-day limit in the last year, and that alone will sink the application.

Good character, English and Life in the UK

These are identical to the standard route, and marriage to a British citizen gives you no latitude on any of them.

Good character covers convictions and cautions — including spent ones, which must still be declared for nationality purposes — fixed penalty notices, driving offences, immigration breaches in the last ten years, unpaid tax, and any deception in an earlier application. Declare everything and explain it. A disclosed issue is often survivable; the same issue found by the Home Office after you failed to mention it is treated as deception and can bar you for ten years.

English must be evidenced at CEFR B1 or above, by an approved Secure English Language Test, a degree taught or researched in English, or nationality of a recognised majority English-speaking country. Exemptions apply if you are 65 or over or have a qualifying long-term condition.

Life in the UK is a 24-question test needing 75% to pass. If you sat it for your settlement application, that pass still counts — keep the reference number.

What it costs and how long it takes

The fee is the same as the standard route. As at 31 August 2026:

• £1,709 application fee
• £130 citizenship ceremony fee
• £1,839 total

The Home Office aims to decide within six months. After a grant you attend a citizenship ceremony, normally within three months, and only then can you apply for a British passport.

The fee is not refunded if the application fails.

What you will need to provide

• Your passport and any previous passports covering the three-year period
• Your marriage or civil partnership certificate
• Evidence your spouse is a British citizen — their passport or certificate of naturalisation or registration
• Proof of your own settled status or indefinite leave to remain, including eVisa or UKVI account details
• Your Life in the UK test reference and English language evidence
• A complete list of absences with dates
• Evidence of residence across the three years — employment, tax, tenancy or mortgage, council tax, GP records
• Two referees, one of professional standing and generally one a British citizen aged 25 or over, both of whom have known you three years and are not related to you or to your adviser

Where these applications go wrong

1. The spouse has ILR, not citizenship. The route simply is not available, and the application is refused.
2. Absences over 270 days. Often by a small margin, and almost always because short trips were not counted.
3. The 90-day rule in the final year, overlooked because the three-year total looked comfortable.
4. A marriage not recognised under UK law, or an earlier divorce that was never properly completed.
5. Undeclared minor matters — a fixed penalty, a spent caution — omitted as irrelevant and then treated as deception.
6. Not being in the UK on the qualifying date exactly three years before the application is received.
