Life in the UK Test ILR vs Citizenship: When Do You Need It?

Published 22 June 2026

If you're planning to settle permanently in the UK or become a British citizen, you'll likely need to pass the Life in the UK test. However, many people are confused about when exactly this test is required and whether passing it once covers both Indefinite Leave to Remain (ILR) and citizenship applications. Understanding the difference between these two immigration milestones—and how the test fits into each—can save you time, money, and stress as you plan your journey.

What Is Indefinite Leave to Remain (ILR)?

Indefinite Leave to Remain, commonly known as ILR or settlement, is your permission to live and work in the UK permanently without any time restrictions. Once you have ILR, you no longer need a visa to stay in the country, though you're not yet a British citizen. Most people apply for ILR after living in the UK for a qualifying period, typically five years on a work visa or family visa, though some routes allow settlement after just two or three years.

For most ILR applications, you must demonstrate your knowledge of British life and the English language. This is where the Life in the UK test comes in. You'll need to pass the test and provide your pass notification as part of your ILR application, unless you qualify for an exemption based on age or medical grounds.

What Is British Citizenship?

British citizenship (naturalisation) is the next step after ILR for many people. As a British citizen, you gain additional rights including the ability to hold a British passport, vote in all UK elections, and live abroad without losing your status. Most applicants can apply for citizenship one year after receiving ILR, provided they meet residency and other requirements.

The citizenship application also requires proof that you understand British life and can speak English. This means you'll need evidence of passing the Life in the UK test for this application as well—but here's the good news.

Do You Need to Take the Test Twice?

No. A pass in the Life in the UK test never expires, so you only need to take and pass it once. If you passed the test for your ILR application, you can use the same pass notification when you later apply for British citizenship. You won't need to sit the test again or pay the £50 fee a second time.

This is an important distinction: whilst ILR and citizenship are separate applications with different requirements, the Life in the UK test result can be used for both. Just make sure you keep your pass notification letter safe, as you'll need the reference number for future applications.

When Exactly Do You Need to Pass the Test?

The timing depends on which application you're making:

Remember, you must book your test online via GOV.UK at least three days in advance at a registered test centre. The test itself consists of 24 multiple-choice questions based on the official handbook, and you have 45 minutes to complete it. You need to score at least 18 out of 24 (75%) to pass. Practising with free mock tests can help you prepare and build confidence before the actual exam.

Key Differences Between ILR and Citizenship Requirements

While both applications require the Life in the UK test, there are other important differences:

Both applications require proof of English language ability and the Life in the UK test, but only one test pass is needed to satisfy both. Keep your documentation organised, and you'll be well-prepared for each stage of your settlement journey.
