ISA Transfers

You can transfer money from an ISA with another provider to us:

  • Complete the ISA Transfer In section during your application
  • We will receive this the next working day, and once your account is opened we will contact your existing ISA provider to arrange the transfer to your Castle Trust Bank account
  • If your current ISA provider doesn't accept electronic signatures and requires an original signature, we will send a form to you via email and you'll need to return this back to us in the post
  • ISA Transfers can take anything from 5-15 working days to complete

For more information on how the process works, take a look at our ISA Transfer Guide.

ISA Transfer Guide

Funding your account

These tips should help you get started with funding your account:

  • When transferring from your nominated account, use Sort Code 60-84-08, your Castle Trust Bank account number, your full name as the payee, and choose the 'Personal account' option rather than 'Paying a company', as the account is held by you. You can also fund your account from an eligible Castle Trust Bank account, using our Self-Service Portal or mobile app.
  • In addition, you can also transfer existing Cash ISAs from other providers to fund your Fixed Rate e-Cash ISA.
