The UK partner route — covering spouses, civil partners, and unmarried partners of British citizens and settled persons — is one of the most heavily used immigration pathways, but also one of the most demanding. Applicants must navigate a multi-stage visa process, meet a financial requirement that has risen sharply in recent years, and produce substantial evidence of a genuine and subsisting relationship at every stage. The reward at the end is Indefinite Leave to Remain (ILR), which removes all immigration conditions and opens the path to British citizenship. This article walks through the route from initial spouse visa to ILR, with emphasis on the rules that changed in 2024 and 2025.
The 5-year and 3-year routes compared
The standard partner route is structured as a 30-month initial visa followed by a 30-month extension, after which the applicant qualifies for ILR — five years in total. Each stage has its own application form, fee, and evidence requirements. The initial visa is applied for from outside the UK (entry clearance) using form VAF4A, or from inside the UK (leave to remain) using form FLR(M). The extension is filed on form FLR(M), and the ILR application is filed on form SET(M).
For spouses and civil partners of British citizens — and only of British citizens — the qualifying period is shortened to three years. The 3-year route does not require a separate application; the applicant simply applies for ILR on form SET(M) after three years of leave as a partner. The reduction reflects Parliament's view that integration is presumed faster when the sponsor is a citizen. There is no equivalent reduction for partners of settled persons (those with ILR); they must complete the full five years regardless of how long the relationship has existed.
Who qualifies for the 3-year route
The 3-year route is available only to partners of British citizens by naturalisation or descent — not partners of settled persons, and not partners of those with pre-settled status under the EU Settlement Scheme. The applicant must have been granted leave as a partner (spouse, civil partner, or unmarried partner) and must have completed three years of continuous residence in the UK on that leave. The three years are counted from the date the initial partner leave was granted, not the date of marriage or the date of first arrival in the UK.
If the applicant's spouse became a British citizen during the relationship — for example, the spouse naturalised in year two of the partner's five-year route — the applicant cannot switch to the 3-year route mid-stream. The 3-year clock starts from the date the applicant's partner visa was granted; if the sponsor was not yet a British citizen at that point, the 5-year route applies. The distinction is technical but important, and applicants in this situation should seek legal advice before applying.
The financial requirement: £29,000 in 2025
The financial requirement for a partner visa has been the subject of controversy and litigation since its introduction in 2012. The threshold was set at £18,600 in 2012 and remained frozen for 12 years, until the Home Office announced a staged increase beginning in April 2024. The threshold rose to £29,000 on April 11, 2024, and is currently £29,000 for initial applications and extensions in 2025. The original plan called for a further rise to £34,500 and eventually £38,700, but the new government elected in July 2024 paused those planned increases indefinitely.
The £29,000 threshold applies to sponsors with no children; an additional £3,800 is required for the first child and £2,400 for each additional child. The income can be met by the sponsor alone, the applicant alone, or a combination. Income from employment must be at the required level for at least six months before the application if the sponsor is employed; self-employed sponsors and those relying on dividend income must meet a more complex 12-month or two-year average test. Savings above £16,000 can be substituted for income at a ratio of 2.5x — meaning £88,500 in savings (above the £16,000 baseline) substitutes for £29,000 of income.
Certain benefits — including Carer's Allowance, Disability Living Allowance, and Personal Independence Payment — exempt the sponsor from the income threshold, replacing it with "adequate maintenance" test. This exemption is narrow and the calculation of adequate maintenance has its own formula, but it is a critical route for disabled sponsors who would otherwise struggle to meet the income requirement.
English language: A1 to B1 progression
The English language requirement escalates at each stage of the partner route. The initial spouse visa requires A1 CEFR; the first extension requires A2; and the ILR application requires B1. The progression is designed to push applicants toward genuine integration rather than rote learning. Each level must be demonstrated by a Secure English Language Test (SELT) from an approved provider — Trinity College London or IELTS SELT Consortium — and the test certificate is valid for two years.
Applicants from majority-English-speaking countries (a list that includes the United States, Canada, Australia, New Zealand, Ireland, and several Caribbean nations) are exempt from the test at every level. Applicants who hold a degree taught or researched in English can meet the requirement with a NARIC statement of comparability. The B1 test costs approximately £150 and consists of a speaking and listening component; reading and writing are not tested for partner-route purposes. Failure to plan for the B1 test in advance is a common reason for delayed ILR applications — applicants who put off the test until their visa is about to expire often find test centres fully booked for months ahead.
Proving the genuine relationship
At every stage of the partner route, the applicant must demonstrate that the relationship is genuine and subsisting. The Home Office caseworker is looking for evidence that the couple lives together, shares finances, and presents themselves to the world as a couple. Standard evidence includes: joint tenancy agreements or mortgage documents; utility bills addressed to both partners at the same address; joint bank accounts; correspondence addressed to each partner at the same address (typically six items spread evenly across the qualifying period); photographs of the couple together at different times and with family; and statements from friends or family attesting to the relationship.
The Home Office pays particular attention to whether the couple actually lives together. Extended periods of living apart — for work, study, or family reasons — require explanation and evidence that the separation was temporary and that the couple maintained contact. Couples who maintain separate addresses for cultural or practical reasons (such as caring for elderly parents) should explain this clearly in a cover letter and provide evidence of regular visits and shared financial commitments. Applications that look like a "marriage of convenience" — minimal joint financial evidence, no shared address, brief acquaintance before marriage — are refused and can lead to a ban on future applications.
Life in the UK test and the SET(M) form
The ILR application on form SET(M) requires the applicant to have passed the Life in the UK test, a 24-question multiple-choice exam based on the official Home Office handbook. The pass mark is 75% (18 of 24 correct), the test costs £50, and it can be retaken as many times as needed. The test must have been passed before the SET(M) application is submitted — booking the test for a date after the visa expires risks leaving the applicant with no valid leave while waiting for the test date. The English language B1 test (or exemption) is also required at ILR stage, even if the applicant passed A2 for the previous extension.
The SET(M) form is filed online and the 2025 fee is £2,885 per applicant, with an additional fee for each dependent child included on the application. Biometric enrollment at a UK Visa and Citizenship Application Services (UKVCAS) centre is required, and the standard decision time is six months — though a super-priority service (£1,000 additional) gives a decision by the end of the next working day. The applicant's existing leave is extended under Section 3C of the Immigration Act 1971 while the application is pending, so work and travel can continue.
