Already registered?

If you've already registered, you can update your personal details such as your phone number, address and email address through Online Services . You can also ask us to do this for you at a branch, or by calling us on 0800 121 8899 .

To tell us that you’ve changed your address

Fill in a change of address form and send it to us at:

FREEPOST CBS CUSTOMER SERVICE

It's important that you write the address exactly like this, in capital letters, all on one line. You don't need a stamp. Royal Mail delivers Freepost as Second Class mail.

If you ask us to change your address, we’ll confirm this in writing by posting a letter to you at both your new address and your old address. We need to do this as a fraud prevention measure.

To tell us that your name has changed

The easiest way to do this is ask us to do this at a branch - bring your documents and we can verify the change and update your details then and there.

Alternatively, you can fill in a change of name form and send it to us, with supporting documents (see below), at: 

FREEPOST CBS CUSTOMER SERVICE

It's important that you write the address exactly like this, in capital letters, all on one line. You don't need a stamp. Royal Mail delivers Freepost as Second Class mail.

Please note: if you change your name with us, we automatically re-issue any cash or debit cards you have for your accounts. You’ll receive them in the post and you can use the same PIN. Your cards with your old name on will become inactive as soon as the new cards are produced.

Documents we need to see if you change your name 

If you want to change your title (for example Mrs to Ms or Ms to Dr), we don’t need to see documentation.

If you want to change your name on your accounts with us, you must show us original documents or certified copies of documents to prove the change. (There’s more about how to certify documents here: Identification)

The documents we need to see depend on what change you’re making. We accept these documents:

  • Marriage Certificate
    (If you get married overseas and have a foreign marriage certificate, please call us or ask at a branch and we’ll explain what we can accept.)
  • Civil Partnership document
  • Certificate of Deed Poll or Deed Poll prepared by UK Deed Poll Service 
  • Statutory Declaration on Change of Name
  • Decree Absolute
  • Civil Partnership dissolution document
  • Birth certificate or Marriage Certificate
    (If you’re changing back to your maiden name. This must be accompanied by a signed letter from you.)
  • Adoption Deed
  • Birth Certificate, re-issued (under 18s only)

We can’t accept passports or driving licences as proof of a name change because they don’t show the link between your old name and new name. 

To add someone to your savings account

Call us on 0800 121 8899 or ask at any branch . If it’s possible to add an account holder to your account, we’ll let you know what information we need from them.
