The Life in the UK test is a computer-based exam testing knowledge of British values, history, traditions and everyday life. Passing it is a requirement for most adults applying for indefinite leave to remain or for naturalisation as a British citizen.
In one line: The Life in the UK test is the knowledge exam most adults must pass to settle in or naturalise as a citizen of the UK.
How the Life in the UK test works
The test has 24 multiple-choice questions drawn from an official handbook, and a pass mark of 75 percent applies, so 18 correct answers are needed within the time limit at an approved test centre.
The standard booking fee is 50 GBP per attempt (Home Office, 2026), and an applicant can retake it as many times as needed, paying the fee each attempt. For example, someone applying for naturalisation in 2026 books a slot, sits the test, and keeps the unique reference number to quote on the application.
The result feeds into ILR and citizenship applications as evidence of the knowledge requirement, alongside any separate English language proof that the route demands.
The test in practice
The Life in the UK test checks knowledge of British life and is distinct from the English language requirement, which is proved separately through a qualification or recognised test.
One pass is generally reusable, so a person who took the test for ILR does not usually need to retake it later for naturalisation, since the same result can support both stages.
