How to open an account on behalf of a child

Up to the age of seven we require an adult to sign an application form on behalf of a child when opening a junior account. Here's how it works: 


  • Decide which account you would like to open, from the list shown here.    
  • Read the Key Product Information in conjunction with our Savings Rate Brochure and General Terms & Conditions
  • Complete and sign the application form for the account you wish to open. This form can be downloaded at the bottom of the account information page.
  • The child’s details need to be completed as Applicant 1 on the application form. If the child is 7 years or over, they will also need to sign as Applicant 1.
  • If there is to be an adult signatory on the account, they should complete and sign the application form as Applicant 2.
  • Further signatories will need to complete an Additional Details form, which is available on request from our customer service team.
  • Take the completed application form into any of our Branches or Agencies, or you can email it to or post it to our Head Office.
    • If you are opening an account in one of our Branches or Agencies make sure you have the correct ID with you as outlined in the application form.
    • If you are opening an account by email please send us a copy of the child's birth certificate, copy of photo id if they have it (eg. passport), a photo of the child (a 'selfie' is fine) and a photo of the front and back of the bank card or a statement showing the nominated account details.  If the account is being opened by an adult other than the parent, we also need to see proof of address for the parents (i.e where the child is living).       
    • If you are opening an account on behalf of a child by post, we’ll let you know what we need when we receive your application form. 
  • You can open your account with a cheque payable to yourself or you can send your initial deposit by faster payment from your nominated account once the Bath Building Society account has been opened.  Please contact our customer service team for further details.
  • We will send you a welcome letter once the account has been opened. If you have any queries at any time, then please contact our customer service team or visit one of our Branches or Agencies.
  • Please note the proceeds in the account belong to and are for the sole benefit of the child.
