Indefinite Leave to Remain (ILR) gives you the right to live and work in the UK permanently — but not a British passport. British citizenship gives you a passport, the right to vote in all elections, and a status that cannot lapse through absence. Both require passing the Life in the UK test. Most people apply for ILR first, then citizenship after one further year of residence. The key difference is permanence: ILR can be lost through absence; citizenship cannot be revoked except in exceptional circumstances.

Quick Overview
✅ Both ILR and British citizenship require passing the Life in the UK test
✅ ILR comes first — citizenship is the step after ILR for most applicants
✅ After ILR, you can apply for citizenship after 1 year of further residence
⚠️ ILR can be lost if you leave the UK for more than 2 continuous years
⚠️ British citizenship acquired by naturalisation cannot normally be revoked
📌 If you are married to a British citizen, you can apply for citizenship after 3 years without needing ILR first
📌 The 2025 Immigration White Paper proposes extending the ILR qualifying period from 5 to 10 years — transitional protections exist for people already in the system. Verify your specific route at GOV.UK
💡 Most people take the Life in the UK test once and use it for whichever application comes first — the pass certificate does not expire
💡 Keep a record of all absences from the UK — UK Visas and Immigration (UKVI) checks your travel history carefully for both ILR and citizenship
What Is ILR?
Indefinite Leave to Remain is the UK's form of permanent residence. When you have ILR, you can:
- Live and work in the UK without any time restriction
- Access public funds and the NHS on the same basis as UK nationals
- Travel to and from the UK freely (with some limits)
- Apply to bring family members to the UK
ILR does not make you a British citizen. You cannot vote in UK general elections or obtain a British passport. If you leave the UK for more than 2 continuous years, your ILR lapses and a new application is required.
Who can apply for ILR?
Most people apply for ILR after a qualifying period on a work or family visa. Common routes include:
- Skilled Worker — typically 5 years' continuous residence (Life in the UK test for Skilled Worker visa ILR)
- Spouse or partner of a British citizen — typically 5 years' residence after the initial family visa
- Long Residence — 10 years' continuous lawful residence in the UK
- UK Ancestry — 5 years on a UK Ancestry visa
Use our ILR eligibility calculator to find your exact eligibility date based on your qualifying period and visa start date. When you are close to applying, our free ILR document checklist helps you confirm every document is in order for your specific visa route.
What Is British Citizenship?
British citizenship (obtained through naturalisation) is the highest immigration status available. Once you are a British citizen, you have the right to:
- Hold a British passport
- Vote in all UK elections, including general elections
- Pass citizenship to your children born overseas
- Return to the UK at any time without immigration restrictions
British citizenship by naturalisation cannot be revoked except in limited circumstances involving fraud or national security. Unlike ILR, it cannot be lost simply through absence.
How long does it take to reach citizenship?
For most people the path is:
- Enter UK on a work or family visa
- Live and work in the UK for 5 years (possibly 10 years under new rules)
- Apply for ILR
- Live in the UK for 1 further year with ILR
- Apply for naturalisation as a British citizen
Under the existing 5-year ILR route, the total minimum from arrival to citizenship is around 6 years. Under the proposed 10-year route (announced May 2025), this would extend significantly. If you are married to a British citizen, you can apply for citizenship after 3 years' residence without needing ILR first. Use our citizenship planner to find your exact citizenship eligibility date and see the total cost breakdown for your route.
Where Does the Life in the UK Test Fit In?
The Life in the UK test is a requirement for both ILR and naturalisation applications. You must have passed it before submitting either application.
You only need to pass the test once. If you pass while applying for ILR, your pass certificate is valid for your citizenship application years later — it does not expire.
The test covers British history, values, culture, government, and law. It is 24 questions, 45 minutes, with a pass mark of 75%. The cost is £50 per attempt.
If you are applying for citizenship (not ILR), some applicants can use an ESOL with Citizenship qualification as an alternative to the standard test.
Should You Apply for ILR or Citizenship?
Apply for ILR first if you have completed your qualifying period and want to secure permanent residence. ILR removes the uncertainty of visa renewals and gives you full rights to work and access public services.
Apply for citizenship when you want a British passport, the right to vote, or the strongest possible status — and you have completed the ILR qualifying period plus one further year.
Apply for citizenship directly (without ILR first) only if you are married to a British citizen and have lived in the UK for 3 or more years — this is a different route.
Common Mistakes to Avoid
❌ Thinking ILR is the same as citizenship ILR gives you the right to live and work permanently in the UK, but not a British passport. You cannot vote in general elections, and your ILR status does not automatically pass to children born overseas. Candidates who apply for ILR assuming it grants full citizenship rights are often surprised to discover the additional steps and fees required for naturalisation.
❌ Letting ILR lapse through absence If you travel outside the UK for 2 or more continuous years, your ILR may lapse — requiring a new application and a new qualifying period. This is a significant consequence of extended overseas travel. Keep a record of all trips and check the rules before any extended overseas period. British citizenship, once granted, does not lapse through absence.
❌ Retaking the Life in the UK test unnecessarily The pass certificate does not expire. If you passed the test for your ILR application, the same certificate is valid for your citizenship application years later — there is no need to retake it. Retaking the test costs £50 and requires preparation time. Always check whether you already hold a valid pass certificate before booking.
❌ Not checking the qualifying period for your specific route The standard 5-year qualifying period applies to most work routes, but varies for some categories and has been subject to proposed changes. The 10-year extension announced in 2025 has transitional arrangements that depend on when you entered the UK. Always verify your specific qualifying period at GOV.UK before making any immigration decisions — general guidance may not apply to your exact circumstances.
❌ Not checking your good character history before applying Both ILR and citizenship require a good character assessment. Criminal convictions, immigration violations, and financial issues can all affect the outcome. Use our free good character checker to assess your situation before submitting.
Frequently Asked Questions
Do I need to take the Life in the UK test twice — once for ILR and once for citizenship?
No. You take the test once. Your pass certificate is valid indefinitely and can be used for both your ILR application and your subsequent citizenship (naturalisation) application.
Can I apply for British citizenship without ILR?
Yes — if you are married to or in a civil partnership with a British citizen, you can apply for naturalisation after 3 years' residence without needing ILR first. This is the spouse route to citizenship.
What happens if I lose my ILR?
ILR lapses if you leave the UK for 2 or more continuous years. If this happens, a fresh visa application and a new qualifying period will be required. Citizenship, once granted, does not lapse through absence.
Is the qualifying period really changing to 10 years?
The 2025 Immigration White Paper proposed extending the qualifying period from 5 to 10 years for most immigration routes, with implementation from April 2026. Transitional arrangements protect people already in the system. Verify your situation at GOV.UK. See our full article on UK immigration changes 2026.
How much does it cost to apply for ILR vs citizenship?
As of 8 April 2026, ILR costs £3,226 per person. The citizenship (naturalisation) fee is £1,709, plus a mandatory £130 citizenship ceremony fee — a total of £1,839. Both fees are set by the Home Office. Check GOV.UK for current figures before applying.
Expert Tips
1. Pass the Life in the UK test before you need it. The test has a 67% first-attempt pass rate. Passing it with 12–18 months to spare before your ILR application removes one variable from an already complex process. Start with free practice questions.
2. Keep a record of your absences from the UK. Both ILR and citizenship applications require a detailed travel history. UKVI checks this carefully. A simple spreadsheet updated as you travel prevents problems later. Use our free UK absence calculator to check if any 12-month window exceeds the 180-day limit.
3. The citizenship ceremony is not optional. After your naturalisation application is approved, you must attend a citizenship ceremony to receive your certificate. The ceremony must be completed within 90 days of approval. Budget for this in your planning.
How This Aligns With Official Guidance
Information on qualifying periods, fees, and requirements is based on GOV.UK guidance. The proposed 10-year qualifying period reflects the Immigration White Paper published May 2025. Always verify current requirements before submitting any immigration application. Last reviewed: April 2026 — figures correct at time of publication. Always check GOV.UK for the latest fees and requirements.
