Most people on a partner or spouse visa can extend their leave using the FLR(M) online form, applying in the UK up to 28 days before their current permission ends. The application must show the same core evidence as your original visa: a genuine relationship, adequate accommodation and proof you meet the financial requirement. If your case is complex, urgent, or your finances have changed, get a solicitor to check your application before you submit it.
TL;DR:
- You must apply for a spouse visa extension within 28 days before your current leave expires, using the FLR(M) online form, to avoid overstaying.
- Valid relationship evidence includes marriage or civil partnership certificates, joint finances, and cohabitation proof of at least two years for unmarried partners.
- The total cost of extending a family visa ranges from £3,000 to £4,000, covering application fees, health surcharge, translation, and legal advice, with processing times often taking several months.
- Preparing a well-organized bundle that matches the Home Office checklist and consulting a solicitor for complex cases can significantly improve the chances of approval.
- Falling short on income does not automatically lead to refusal, but applicants must present strong, corroborated evidence of exceptional circumstances if relying on a lower financial threshold.

Who can apply for a spouse visa extension in the UK?
Your eligibility for a spouse visa extension rests on your sponsor’s immigration status and the strength of your relationship evidence. Your sponsoring partner must be British, Irish, settled in the UK, or hold another qualifying status recognised under Appendix FM of the Immigration Rules. Unmarried couples need to show at least two years of cohabitation, not just a serious relationship on paper.
The rules recognise three relationship categories for extension purposes:
- Married couples, with a valid marriage certificate
- Civil partners, with a civil partnership certificate
- Unmarried partners who have lived together for at least two years, evidenced through joint tenancy agreements, bills, and correspondence
Timing matters as much as eligibility. You must apply while still in the UK, and normally within 28 days of your current leave expiring, using the FLR(M) route as a partner or spouse. Miss that window without a good reason and you risk becoming an overstayer, which complicates everything from future applications to your eventual indefinite leave to remain eligibility. If you are outside the UK when your leave expires, you will usually need a fresh entry clearance application rather than an in-country extension, which follows a different process and timeline entirely.
What documents does a spouse visa extension need?
Home Office caseworkers look for four categories of evidence, and gaps in any one of them are the most common reason extensions stall. Getting the paperwork right the first time avoids a Home Office request for further information, which can add weeks to your case.
- Identity documents: current passport, biometric residence permit (BRP), and any prior Home Office correspondence confirming your immigration history.
- Relationship evidence: marriage or civil partnership certificate, joint bank statements, a shared tenancy or mortgage, utility bills in both names, photographs spanning your relationship, and message or call records showing ongoing contact if you have spent time apart.
- Financial evidence: recent payslips, an employer letter confirming salary and start date, bank statements matching those payslips, and savings evidence if you are relying on capital rather than income. Anyone who submitted their original spouse visa application before 11 April 2024 may still qualify under the earlier, lower financial threshold, which changes which payslips and statements you actually need.
- Accommodation evidence: tenancy agreement or mortgage statement, council tax bill, and confirmation from a landlord or local authority that the property is large enough for everyone living there.
You’ll also need to meet the English language requirement, usually through an approved test or a degree taught in English, and attend a biometric appointment to have your fingerprints and photograph taken.
Pro Tip: Label every document with a short description and page number, then submit them in the order the FLR(M) checklist lists the requirements. Caseworkers process hundreds of files a week, and a bundle that mirrors their checklist gets read faster and misunderstood less often.
How much does a spouse visa extension cost, and how long does it take?
Budget more than just the headline visa fee. Citizens Advice puts the total cost of extending a family visa at roughly £3,000 to £4,000, once you factor in the application fee, the Immigration Health Surcharge, translation costs, and any legal advice.
Three things drive that final figure:
- The Home Office application fee itself, which changes periodically
- The Immigration Health Surcharge, charged per year of the visa granted
- Optional costs such as document translation, courier services, or legal representation
Exact fee amounts move regularly, so always check the current figures on GOV.UK before you pay. Processing times move too. UKVI publishes live estimates on its visa processing times page, and standard in-country decisions often take several months, though premium or priority services can be faster where available. A grant under FLR(M) typically runs for 2 years and 6 months, bringing most applicants closer to the five-year point at which ILR becomes possible.
How do you submit an FLR(M) extension application?
The process runs in a fixed sequence, and skipping steps out of order is where most delays start.
- Create or log into your UKVI account and open the FLR(M) online form.
- Complete every field carefully, checking dates and personal details against your passport and BRP before submitting.
- Pay the application fee and the Immigration Health Surcharge at the same stage.
- Book your biometric appointment once payment clears.
- Compile your evidence into labelled bundles, ideally scanned in the order the online guidance requests them.
- Attend your biometric appointment and upload any outstanding documents through your UKVI account.
- Track your application’s progress online and respond promptly to any Home Office request for further evidence.
If your leave is expiring within days, your finances sit close to the threshold, or you’ve had a previous refusal, a solicitor can review your bundle before submission and flag weaknesses you might miss. Firms offering fast-track preparation can turn around a full application within 24 hours when time is genuinely short.
What if you don’t meet the financial requirement?
Falling short on income doesn’t automatically end your case, but the Home Office scrutinises alternative arguments hard. Citizens Advice is blunt about this: exceptional circumstances are interpreted strictly, and applicants who lean on this ground without strong documentary proof are refused more often than they succeed.
Common causes of refusal include:
- Relationship evidence that’s thin, inconsistent, or covers too short a period
- Income or savings that fall just below the required threshold with no transitional protection
- Accommodation evidence that doesn’t clearly show adequate space for the household
- Unpaid NHS debts, which can block an extension outright regardless of other evidence
Pro Tip: If you’re arguing exceptional circumstances, gather contemporaneous, third-party corroboration, such as medical letters, school records, or employer statements, rather than personal statements alone. Caseworkers weigh independent paperwork far more heavily than your own account of events.
A solicitor’s view on when legal help actually changes the outcome
Legal help earns its cost most clearly when evidence is borderline, finances have shifted since your last grant, or your leave expires within weeks. At Mnssolicitors, every enquiry is handled by a qualified solicitor from the first conversation, not a trainee, which matters when a caseworker’s read of your relationship evidence could go either way. Fixed pricing and same-day preparation for urgent cases mean you know the cost and the timeline before you commit.
