To apply for British citizenship, you must meet the Knowledge of Language and Life in the UK (KoLL) requirement. This means proving your English language skills and passing the Life in the UK Test. Here’s everything you need to know.
KoLL requirement explained: What is required for British naturalisation?
You must show:
English language ability: Prove you can speak and understand English at B1 level or higher. From January 2026, migrants applying for major UK visa routes must prove B2-level English (equivalent to A-level standard) under the CEFR.
Life in the UK knowledge: Pass the Life in the UK Test about British culture, history, and laws.
If you already met these when getting Indefinite Leave to Remain (ILR), you usually don’t need to do them again.
UK English language requirement
You can prove your English in one of these ways:
Pass an approved test (SELT) at B1, B2, C1 or C2 level.
Hold a degree taught in English, confirmed by UK ENIC if it’s from abroad.
If your degree was taught in English, you can use it as proof.
If it’s from outside the UK, you must get confirmation from UK ENIC (Ecctis) that it was taught in English.
Be from a majority English-speaking country (like the USA, Canada, or Australia). See full list here.
When you don’t need to take a test?
You’re exempt if:
You’re under 18 or over 65.
You have a long-term physical or mental condition that prevents you from taking the test (you’ll need medical proof).
You already met the English requirement when you got ILR.
Life in the UK Test
You must pass the Life in the UK Test to show you understand British life and values. You’ll be tested on information from the official handbook “Life in the United Kingdom: A Guide for New Residents”, including:
British history and major events
Government and law
Culture and traditions
Everyday life and community
Rights and responsibilities of residents

Big picture
Meeting the English language and Life in the UK test requirements is a key step toward British citizenship. These tests prove that you can communicate in English and understand how life, law, and culture work in the UK.
By preparing early, using official study materials, and choosing an approved test provider, you can meet both parts of the KoLL requirement smoothly. Once passed, you’ll be ready to complete your UK naturalisation application with confidence and take the final step toward becoming a British citizen.
