Use this service if you:
- want us to confirm that we can find no evidence that you or someone else acquired British citizenship through naturalisation. We can confirm this up to October 1986 – for confirmation from October 1986 onwards apply through UK Visas and Immigration
- want a headed letter from us confirming this, for legal reasons
We can search the British citizenship records up to October 1986 held by The National Archives. If the subject of your request did not obtain British citizenship there will be no record and we will confirm this.
If you want to check whether someone held British citizenship from October 1986 onwards, contact UK Visas and Immigration.
If you meant to request a search for a certificate of British citizenship, use this service.
How it works
Click on ‘Start now’ below to complete the form. Once completed, click ‘Submit’ and we will conduct a search based on the information submitted at no charge to you.
We will email you with the results of the search within 10 working days.
If we find no evidence of British naturalisation, we will confirm this in the email. If you need this information for legal use, we will conduct a second search, carried out by a different team, and issue a signed letter confirming no evidence has been found. There is a charge for the letter and second search.
We will issue and send the letter within 16 working days of payment.
How much does the letter and second search cost?
Each headed letter confirming no evidence of naturalisation costs £27.15 GBP.
If you need more than one copy of the headed letter – for example, for a family member – you will need to fill in this form again, using their contact details.
