Funding your account

The easiest way to fund your savings account is by making a bank transfer. This should be made from your nominated account, using the Sort Code 60-84-08 and your Castle Trust Bank account number (which you will find on your welcome letter and on the Self Service Portal). You can also fund your savings account by sending us a cheque, or by debit card through the Self Service Portal.

Fixed Rate Cash ISAs can also be funded by transferring the cash value of an existing ISA from another ISA Manager.

When you open your account, you will have a 14 day funding window to make your deposit(s) into your account to meet the minimum required balance. For fixed rate accounts, after this time you will not be able to make any further deposits.

We're here to help you get started on the Self Service Portal

Since launching our new Self Service Portal in the summer, many of our customers have already registered to manage their savings online. We have a support area to help you take your first steps to managing your savings online.
