Nationality checking service

We work in partnership with the Home Office to provide a service to help applying for British citizenship.

The Nationality Checking Service (NCS) will help ensure that your citizenship application is properly completed and submitted with all the relevant supporting documents.

All adult applicants for naturalisation will need to demonstrate knowledge of life in the United Kingdom. The aim is to ensure that new British citizens are equipped with basic level understanding of British culture, customs and life in UK in general.

You can apply for British citizenship if:

  • you are over 18
  • you are of good character, you don’t have a serious or recent criminal record, and you haven’t tried to deceive the Home Office or been involved in immigration offences in the last 10 years
  • passed the Life in the UK test
  • an English for Speakers of Other Languages (ESOL) qualifications at B1, B2, C1 or C2 level from an approved test centre
  • a degree taught or researched in English . If done abroad an original letter or certificate from UK NARIC on 0871 330 7033 confirming the equivalent level of your degree, plus an official letter from your university with your name and degree confirming that your degree was taught in English.

Nationalities that are exempt

You won’t need to prove your knowledge of English if you are a citizen of these countries.

The Nationality Checking Service does NOT offer:

  • a priority service for processing your application with the Home Office (however, complete and accurate forms are processed on average, more quickly than those that are incomplete or which need further enquires.)
  • any advice on nationality other than in relation to the completion of the application form
  • any advice on other matters such as visas, immigration or asylum
  • we cannot act as agents for the applicant. Further enquiries about your application progress or the decision should be made to the Home Office

If you require further advice, please contact the Home Office .
