Regulated legal advice. Fixed fees. Support from start to decision.
What is an extension of leave?
Extension of leave applications, also known as further leave to remain, allow a person already in the UK with permission to remain in the same or a related immigration route. They are made on different forms depending on the route, including FLR(M), FLR(FP), FLR(IR), and the relevant in-country forms for work routes such as Skilled Worker.
The eVisa context
The UK has moved to an eVisa system. Most applicants no longer receive a physical Biometric Residence Permit. Once an extension is granted, status is held digitally in the UKVI online account and evidenced by a share code. We assist with linking accounts and verifying the position post grant.
The main extension routes
Partner route under Appendix FM (FLR(M))
For partners on the 5 year route, after the initial 33 month period. Granted for 30 months. Requirements include:
- Continuing genuine and subsisting relationship.
- Financial requirement of at least £29,000 gross annual income, or the relevant transitional figure where the route began before 11 April 2024.
- English language at CEFR Level A2.
- Adequate accommodation.
- Continuing intention to live together permanently in the UK.
For full details of the partner route, see our Spouse Visa page.
Family and private life route (FLR(FP))
For applicants on the 10 year partner, parent or private life route. Granted in 30 month tranches. The financial requirement does not apply, but EX.1 and EX.2 of Appendix FM, or the private life provisions in Appendix Private Life, must be engaged.
Family and human rights based applications (FLR(IR))
For applications on the basis of family and private life that fall outside the routes above, including some discretionary cases.
Skilled Worker extension
For sponsored workers continuing in employment with the same or a new sponsor. Requirements include:
- A new Certificate of Sponsorship.
- The relevant going rate and general salary threshold for the occupation.
- The English language requirement, set at CEFR Level B1 from January 2026 for new applicants, with B2 required for ILR.
Other routes
We also advise on extensions across the Global Talent, Innovator Founder, Student, Graduate, Senior or Specialist Worker, and Representative of an Overseas Business routes, and on switching between categories where in-country switching is permitted.
Out of time applications
Where an application has not been submitted before existing leave expires, the position is serious but sometimes recoverable. Paragraph 39E of the Immigration Rules permits limited disregard of overstaying where the application is made within 14 days of the end of leave and there is good reason. We advise urgently in such cases.
Documents commonly required
- Current passport and previous passports covering the period of UK leave.
- Evidence of current immigration status (eVisa share code or BRP).
- Relationship and financial evidence on partner route applications.
- EX.1 and EX.2 evidence on the 10 year route.
- Certificate of Sponsorship and salary evidence on Skilled Worker extensions.
- English language qualification at the level required for the route.
- Evidence of accommodation where required.

Frequently asked questions
How long can I stay in the UK after submitting an extension application?
If the application is submitted before existing leave expires, leave is automatically extended under section 3C of the Immigration Act 1971 until the application is decided. This is known as 3C leave.
What happens if my application is refused?
There may be a right of administrative review or, in human rights cases, an appeal. We advise on remedies and on the option of a fresh application where appropriate.
I have a Biometric Residence Permit. Do I still need it?
The eVisa system has replaced new BRPs. Existing BRPs may still be relied on for the period of validity stated on the card, but the UKVI online account is the primary record of status. We advise clients on the eVisa transition where it affects their case.
Can I work while my application is pending?
Yes, while you have 3C leave on the same conditions as your previous grant of leave. If you are switching between routes, the conditions of the previous leave continue to apply until decision.
When can I apply for ILR after my extension?
For most partner route applicants, after 5 years of continuous leave on the route. For most Skilled Worker applicants, also after 5 years. The 10 year long residence and family routes have their own qualifying periods.
