Change your name

To change the name on your account you'll need to send in an original or certified copy of your marriage certificate, decree absolute or deed poll document plus examples of your old and new signatures.

Please post this information to:

The Co-operative Bank
PO Box 4931
Swindon
SN4 4PL

Once we receive your change of details, we'll update your name and confirm this in writing to you. We'll also return any supporting evidence you've provided. This usually takes between 7-10 working days.

If you don't want to post your documents, you can take them into your local Co-operative Bank branch.
