Updating your details

If any of your personal details change, please get in touch.

Updating your name

You’ll need to write to us with the reason why you’re changing your name. You’ll also need to provide your old and new signatures, together with original documents -we’ll return everything to you as soon as we’ve finished with it. You might want to send documents to us by recorded delivery so you can check they’ve reached us safely.

Documents we can accept

  • Dissolved civil partnership papers


Other situations

Double-barrelled names
