Knowledge of Language (KOL) Requirement for British Citizenship

Updated 27 March 20268 min read

What you need to know

British citizenship applicants must demonstrate English language ability at B1 level (CEFR) in speaking and listening. This can be shown through an approved test, a degree taught in English, or nationality of an English-speaking country. The requirement is the same as for ILR.

What B1 Level Means

B1 on the Common European Framework of Reference (CEFR) is an intermediate level of English. At B1, you can:

  • Understand the main points of clear speech on familiar matters (work, school, leisure)
  • Deal with most situations that arise while travelling
  • Describe experiences, events, hopes, and ambitions
  • Give reasons and explanations for opinions and plans

For citizenship, only speaking and listening skills are tested. You do not need to demonstrate reading or writing ability, though the Life in the UK test requires you to read questions in English.

How to Prove Your English

Option 1: Approved English Language Test

Take one of the approved English language tests:

  • IELTS Life Skills B1: A speaking and listening test, about 22 minutes long. Cost around £150.
  • Trinity College London GESE Grade 5: An oral exam with an examiner, about 10 minutes. Cost around £150.

You must take the test at an approved test centre. Results are usually available within a few days.

Option 2: Degree Taught in English

If you hold a degree that was taught in English (from the UK or overseas), this is accepted as proof of English ability. You may need a statement from UK ENIC confirming the qualification.

Option 3: Nationality

If you are a national of a majority English-speaking country, you are exempt from taking a test. See our exemptions guide for the full list of qualifying countries.

Reusing Your ILR Test

If you passed an English language test for your ILR application, you can use the same certificate for citizenship. The test does not need to be retaken. Keep your certificate safe — you will need it for the citizenship application.

If you have lost your certificate, contact the test provider (IELTS or Trinity) for a replacement or verification letter.

Exemptions

You are exempt from the KOL requirement if:

  • You are aged 65 or over
  • You have a long-term physical or mental condition that prevents you from meeting the requirement (with medical evidence)
  • You are a national of a majority English-speaking country

For full details on exemptions, see our English language exemptions guide.

Preparing for the Test

If you need to take a test:

  • Practice with sample tests available on the IELTS and Trinity College websites
  • Focus on speaking clearly and listening carefully — these are the only skills tested
  • Take a preparation course if you are not confident (many are available online and at local colleges)
  • Book your test well in advance — popular test centres fill up
