Leave to Remain vs Indefinite Leave to Remain: Key Differences Explained

Key points

• Leave to Remain is temporary permission to stay in the UK, granted for a fixed period with conditions attached; Indefinite Leave to Remain is permanent settlement with no time limit and far fewer restrictions.
• Most work and family visa holders pay the Immigration Health Surcharge of £1,035 per year while on limited leave, but this charge does not apply once ILR is granted.
• The five-year qualifying period for ILR on most work and family routes is expected to increase to ten years under the Government’s earned settlement proposals, with implementation planned for April 2026.
• Section 3C of the Immigration Act 1971 protects applicants who submit an extension or settlement application before their existing leave expires, continuing their lawful status until a decision is made.
• ILR lapses automatically if the holder spends more than two consecutive years outside the UK, while limited leave expires on a fixed date regardless of whether the holder is in the UK or abroad.

Two forms of immigration permission

UK immigration law draws a clear line between temporary and permanent residence. For anyone on a work or family visa, understanding that line is essential, because it determines your rights, your obligations, and the cost of remaining in the UK over time.

Leave to Remain and Indefinite Leave to Remain are both granted under section 3 of the Immigration Act 1971. They share the same statutory origin but operate in fundamentally different ways. Leave to Remain is time-limited and subject to conditions. Indefinite Leave to Remain removes those time limits and, in most respects, places you on the same footing as a British citizen.

What is Leave to Remain

Leave to Remain (often referred to as limited leave to remain) is temporary permission granted by the Home Office allowing a person to stay in the UK for a specified period. Section 3(1)(a) of the Immigration Act 1971 provides that a person who is not a British citizen may be given “leave to enter or remain in the United Kingdom” for a limited period, subject to conditions.

Common visa categories that grant limited leave include:

• Skilled Worker visa (typically granted for up to five years).
• Health and Care Worker visa.
• Family visa under Appendix FM (granted in 30-month periods).
• Student visa.
• Graduate route.
• Innovator Founder visa.

Each category carries its own conditions. A Skilled Worker Visa holder must remain employed by their sponsoring employer in the approved role. A spouse visa holder must continue to meet the relationship, financial, and accommodation requirements of Appendix FM. When limited leave approaches its expiry date, the holder must apply for an extension, switch to a different eligible route, apply for ILR if qualified, or leave the UK. Failing to act before leave expires results in overstaying, which carries serious consequences including potential re-entry bans.

What is Indefinite Leave to Remain

Indefinite Leave to Remain, granted under section 3(1)(b) of the Immigration Act 1971, is permanent permission to remain in the UK with no time limit attached. It is also known as settlement. Once granted, the holder may live, work, study, and access public funds without restriction. There is no requirement for employer sponsorship, no restriction on the type of work, and no prohibition on recourse to public funds.

ILR also opens the door to British citizenship. After holding ILR for 12 months (or immediately, for those married to a British citizen), the holder becomes eligible to apply for naturalisation under section 6 of the British Nationality Act 1981.

Eligibility for ILR

The standard qualifying period for most settlement routes is five years of continuous lawful residence in the UK. This applies to the Skilled Worker visa, the Health and Care Worker visa, family visas under Appendix FM, and the Ancestry visa. Some routes offer shorter timelines: the Global Talent visa and Innovator Founder visa may permit settlement after three years.

In addition to completing the qualifying period, applicants must:

• Pass the Life in the UK Test.
• Demonstrate English language proficiency at CEFR B1 level or above.
• Satisfy the good character requirement, assessed with reference to criminal history, tax compliance, immigration record, and honesty.
• Ensure absences from the UK have not exceeded 180 days in any 12-month period during the qualifying residence.

Application costs compared

The financial burden of the two statuses is one of the most significant practical differences. Limited leave requires repeated applications and annual health surcharge payments. ILR is a one-off cost, and settlement removes the obligation to pay the Immigration Health Surcharge. The fees below are effective from 9 April 2025.

Fee	Limited leave (FLR(M) spouse extension)	Limited leave (Skilled Worker extension, up to 3 years)	Indefinite Leave to Remain
Application fee	£1,321 per person	£885 per person (if applying inside the UK). If applying from outside the UK for up to 3 years, the fee is £769.	£3,029 per person
Immigration Health Surcharge	£1,035/year (adult)	£1,035/year (adult)	Not payable
Total for grant period (adult)	£3,908.50 (2.5 years)	£3,990 (3 years)	£3,029 (one-off)
Life in the UK Test	Not required at extension	Not required at extension	£50
Priority service (optional)	Generally not available	Available (£500)	£500
Super Priority (optional)	Available (£1,000)	Available (£1,000)	£1,000

A spouse visa holder who enters the UK on a 30-month initial visa and then extends for a further 30 months will pay the application fee and IHS twice before reaching the five-year ILR qualifying point. The cumulative cost of limited leave, including two rounds of IHS payments, typically exceeds the single ILR application fee. Each dependant, including children, pays the full ILR fee of £3,029 individually. A family of four therefore faces a combined ILR cost of £12,116 before additional charges.

Rights and restrictions compared

	Limited Leave to Remain	Indefinite Leave to Remain

Access to public funds	Normally prohibited (“no recourse to public funds”)	Full access, subject to standard eligibility rules
Immigration Health Surcharge	Payable on each application	Exempt
Travel	Must maintain valid visa; absences risk breaking continuous residence	Free to travel; lapses only after 2+ consecutive years abroad
Conditions	Work, study, and conduct restrictions may apply	No immigration conditions
Citizenship pathway	Cannot apply directly for naturalisation	Eligible after 12 months

Section 3C leave and the transition from limited leave to ILR

One of the most practically important provisions for anyone transitioning from limited leave to ILR is section 3C of the Immigration Act 1971. Where a person submits a valid application to extend or vary their leave before their existing permission expires, section 3C automatically continues their previous leave on the same conditions until the Home Office makes a decision. This protection also extends through any period during which an administrative review or in-country appeal is pending.

Section 3C leave does not apply where the application is submitted after existing leave has expired. In that situation, the applicant becomes an overstayer immediately, and any subsequent work is unlawful for both the individual and the employer. The Supreme Court considered the operation of section 3C in R (Mirza) v Secretary of State for the Home Department [2016] UKSC 63, confirming that where an application is treated as invalid, section 3C leave does not arise because no valid application is pending.

How ILR can be lost

ILR is permanent, but it is not unconditional. Under Article 13(4)(a) of the Immigration (Leave to Enter and Remain) Order 2000, ILR lapses automatically if the holder remains outside the UK for a continuous period of more than two years. Once lapsed, the holder must apply for entry clearance as a returning resident, demonstrating strong ties to the UK during their absence. A person who returns briefly every two years solely to preserve their ILR, without genuinely residing in the UK, risks having their status cancelled at the border. ILR may also be revoked where it was obtained by deception, or where the holder commits a serious criminal offence that leads to a deportation order.

Routes that lead to settlement and routes that do not

A critical point for anyone holding limited leave is that not all visa categories lead to ILR.

Routes that lead to ILR (standard five-year qualifying period unless stated):

• Skilled Worker visa.
• Health and Care Worker visa.
• Global Talent visa (three years).
• Innovator Founder visa (three years).
• Family visas under Appendix FM (spouse, partner, parent).
• Ancestry visa.

Routes that do not lead directly to ILR:

• Student visa.
• Graduate route (two-year post-study work; no direct path to settlement).
• Youth Mobility Scheme.
• Visitor visa.
• High Potential Individual visa.

A student visa holder who wishes to settle must switch to a qualifying route and complete the required period of continuous lawful residence on that route. Time spent on a student visa does not count towards the five-year Skilled Worker qualifying period, although it may count towards 10-year long residence under paragraph 276B of the Immigration Rules.

The earned settlement proposals

The Government’s May 2025 White Paper, “Restoring Control Over the Immigration System,” proposed extending the standard qualifying period for ILR from five years to ten years for most work visa routes. A public consultation closed on 12 February 2026, and implementation is expected from April 2026. The key elements include:

• A 10-year baseline qualifying period for most sponsored workers.
• A 15-year qualifying period for roles below degree level (RQF level 6).
• Points-based “earned settlement” factors that may reduce the qualifying period; high earners with taxable income above £50,270 for three years may retain the five-year timeline.
• Abolition of the 10-year long residence route.
• Partners of British citizens on Appendix FM routes are expected to retain their current five-year pathway.

Anyone currently holding limited leave on a work route and approaching the end of their five-year qualifying period should consider whether to submit their ILR application before the new rules take effect.

Practical guidance

• Track your absence days carefully. The 180-day rule in any 12-month period is strictly enforced and is the single most common reason for ILR refusal.
• Submit any extension or ILR application before your current leave expires. Section 3C protection only applies to in-time applications.
• Keep organised records of your immigration history, travel dates, payslips, and tax returns from the start of your qualifying period.
• Check whether your visa route leads to settlement. If it does not, consider whether switching to a qualifying route is possible and advisable.

Concluding comments

The transition from limited leave to settlement represents the most significant upgrade in immigration status available short of British citizenship itself. Limited leave keeps you in the UK on borrowed time, subject to conditions, renewal obligations, and annual surcharge payments. ILR removes those burdens and provides a stable, long-term foundation. As the earned settlement proposals take shape, planning for that transition early, and understanding the legal and financial differences between the two statuses, ensures the best possible outcome.

FAQs

Can I apply for ILR before my current visa expires?

Yes, you can apply for ILR as soon as you have completed the qualifying period of continuous lawful residence, typically five years. Applying before expiry ensures section 3C of the Immigration Act 1971 protects your lawful status while the decision is pending.

Does time on a student visa count towards the five-year ILR qualifying period?

No, time spent on a student visa does not count towards the five-year qualifying period on work or family routes. It may, however, count towards the 10-year long residence route under paragraph 276B of the Immigration Rules, provided you have maintained continuous lawful residence throughout.

What happens if my ILR application is refused?

You will receive a written refusal notice setting out the reasons. Depending on the circumstances, you may be able to seek an administrative review, submit a fresh application with corrected evidence, or challenge the decision through an appeal on human rights grounds. If you applied in time, section 3C leave continues during any administrative review or appeal period.

How much does ILR cost compared to extending my visa?

The ILR application fee is £3,029 per person, with no Immigration Health Surcharge payable. A Skilled Worker extension (in-country, up to 3 years) costs £885 plus £1,035 per year in IHS. A spouse extension under FLR(M) costs £1,321 plus £1,035 per year in IHS. Over multiple extensions, limited leave is typically more expensive than ILR in cumulative terms.

Will the earned settlement proposals affect people already on a work visa in the UK?

The consultation document indicates that anyone in the UK who has not yet obtained ILR may be affected by the new framework once implemented. The Government has stated there will be some transitional arrangements, but details have not been confirmed. Those nearing the end of their current five-year qualifying period should seek professional advice on whether to apply before the new rules take effect.
