UK Spouse Visa Extension and ILR: The Route to Settlement

The UK spouse visa is not a one-time application. It is the start of a defined immigration pathway that ends at Indefinite Leave to Remain (ILR) — and eventually British citizenship. The standard route takes five years. Some applicants end up on the 10-year route. The requirements change at each stage, including a higher English language level at extension and a different financial calculation for ILR. Here is how the full route works.

The Standard 5-Year Route

Stage 1: Initial visa Out-of-country: 33-month visa from entry into the UK. In-country: 30-month leave to remain.

Stage 2: Extension (FLR(M)) Apply before your initial visa expires. The extension gives another 30 months. English language requirement increases from A1 to A2 at this stage. All other requirements — financial threshold, relationship evidence, accommodation — must still be met.

Time spent in the UK on a fiancé(e) visa does not count toward the five-year qualifying period for ILR.

Stage 3: Indefinite Leave to Remain After 60 months (five years) of continuous residence in the UK on the partner route, you can apply for ILR using the SET(M) form. The ILR application fee is £3,226 (2026 rate). There is no IHS payment at ILR stage.

ILR Requirements at the 5-Year Stage

Life in the UK test: Must be passed before applying. The test covers British history, culture, and values. It costs £50 and must be booked through an official test centre.

English language at B1: Higher than the A2 required for extension. The B1 test must also be a Secure English Language Test from an approved provider. Citizens of majority English-speaking countries and those with ECCTIS-verified degrees are exempt.

Financial requirement: You must still demonstrate the financial threshold is met. For new applicants (entered the route after April 2024): £29,000. For transitional applicants: £18,600 (plus any child additions).

The cash savings calculation changes at ILR: For initial and extension applications, the savings formula is (shortfall × 2.5) + £16,000. At ILR, the 2.5 multiplier is removed. Any eligible savings above £16,000 offset the income shortfall on a 1:1 basis. This makes the cash savings requirement significantly lower at ILR compared to the earlier stages.

Continuous residence: You must not have spent more than 180 days outside the UK in any 12-month period during the five years. Extended absences can disqualify the ILR application on continuity grounds.

Relationship still subsisting: You must still be in a genuine and subsisting relationship with the same UK-based sponsor. If the relationship has broken down, ILR under the partner route is not available (though there may be other routes, including those for domestic abuse victims).

What Happens After ILR: British Citizenship

Once ILR is granted, the holder can apply for naturalisation as a British citizen after 12 months with ILR — or immediately if they are married to or in a civil partnership with a British citizen, provided the continuous residency requirements are met:

• Have been legally resident in the UK for at least three years before applying
• Have not been absent from the UK for more than 270 days in the three years preceding the application, or more than 90 days in the final year
• Hold ILR and pass the good character requirement

Naturalisation as an adult costs £1,709 (2026 rate).

The 10-Year Route to Settlement

If an applicant cannot meet the standard eligibility requirements — most commonly the financial threshold — but qualifies under Article 8 on exceptional circumstances grounds, they are placed on the 10-year route rather than the standard 5-year route.

The 10-year route requires four 30-month extensions before ILR eligibility:

1. Initial visa (out-of-country: 33 months, or in-country: 30 months)
2. Extension 1 (30 months)
3. Extension 2 (30 months)
4. Extension 3 (30 months)
5. ILR after 120 months total continuous residence

At ILR on the 10-year route, the Life in the UK test and B1 English are still required. The financial threshold applies differently — if the exceptional circumstances that originally justified the 10-year route persist, strict financial threshold compliance is assessed differently under GEN.3.1.

Total government fees on the 10-year route (adult, no dependants): approximately £20,378.50 compared to £12,389.50 on the 5-year route. The additional cost is roughly £8,000 — entirely a result of not meeting the income threshold at the initial application stage.

The Extension Application: Timing and Process

Apply for your extension before your current visa expires. The standard processing time is 8 weeks. Submit at least 2–3 months before expiry to allow for processing, potential information requests, and any delays.

While your extension application is pending with a valid "section 3C leave" in place, you can legally remain in the UK. Your existing conditions (including permission to work) continue until a decision is made. Do not travel outside the UK while your extension application is pending without advice on the travel implications for your status.

The FLR(M) extension form requires the same core evidence as the initial application — financial documents, relationship evidence (cohabitation evidence is now more important), and accommodation. English language evidence at A2 level must be submitted.

Planning the Full Route

The partner route is a long-term commitment with significant ongoing costs. Planning ahead — particularly around the income threshold, language tests at each stage, and the Life in the UK test — prevents last-minute scrambles before each renewal deadline.
