British citizenship services

We offer two services relating to British citizenship. Submit a request form below depending on if you want:

1. Evidence that someone obtained or renounced British nationality

  • We will carry out a search of our records of British nationality from January 1949 to October 1986 (or to December 1982 for a renunciation).
  • If we find a certificate, we will provide the certificate number and explain how to order a copy.
  • The initial search is free of charge.

Many certificates, including those issued before January 1949, can be located by a simple name search in our catalogue. Try a search there yourself first, as you may not need to use this service.

2. A letter confirming that someone did not obtain British nationality

  • We will carry out a search of our records of British nationality from November 1844 to October 1986.
  • If we do not find evidence of British nationality, we will send you a letter signed in wet ink confirming this.
  • There is a non-refundable charge of £27.15 for this service, covering the search and the letter.
