You cannot renounce your citizenship or nationality if you do not hold another citizenship or nationality or will not acquire another citizenship or nationality within 6 months as doing so could make you stateless.
Applying for a duplicate certificate (form NC)
Select this option if you have lost or damaged a citizenship certificate that was issued after October 1986 and want a new one. You cannot use this form to replace a certificate that was issued before October 1986. For anything before October 1986, you need to contact the National Archives
Applying for a letter to confirm your immigration status (form NS)
