If your naturalisation or registration certificate is lost, stolen or damaged, or has a mistake on it, you can apply to UK Visas and Immigration for a replacement or correction. Most people need the certificate only once, for a first British passport, but a replacement can be needed for a child's application or for records abroad.

Who can apply

If you became British after 30 September 1986, apply to UKVI online (in the UK) or by post.
If you became British on or before 30 September 1986, UKVI cannot replace the certificate; you request a certified copy from The National Archives instead.

Fee

£456, correct on 13 October 2026. The same fee applies to a correction where the mistake was yours; if it was the Home Office's error, UKVI writes to confirm whether a fee is due.

What you need

For a replacement: your details, the date and place of the ceremony or registration, any reference numbers, and identity evidence. A stolen certificate must be reported to the police and the crime reference given. For a correction: the correction form, the original certificate and evidence of the correct details.

This is not a complete list. What you need depends on your circumstances, and the documents vary from case to case. Your solicitor will tell you exactly what applies to you.

Do you actually need it?

Often you do not. A British passport is proof of citizenship, and the Home Office can confirm citizenship by letter in some situations. We check what the body asking for the certificate will accept before you pay the fee.

What we do

We prepare and submit the application, deal with UKVI's questions, and where the citizenship record itself is in doubt we obtain the Home Office records that prove it.
