Apply online with the Self Service Portal

Since launching our new Self Service Portal last summer, many of our customers have already registered to manage their savings online. With all of your details already stored in our system, you can apply for a new account in minutes once your Self Service Portal access is set up.

Our Self Service Portal makes it easy for you to keep on top of your Castle Trust Bank accounts online. Once your log in has been activated you'll be able to:

Please note, log in details used for our previous Self Service Portal (for customers who held a Castle Trust investment) will no longer work and we have sent new credentials to customers who have provided us with a mobile phone number, email address and nominated bank account. Passwords are provided by email so please check your spam folders if you have not received them, or contact us to set up new log in credentials.

Our Best Rate Promise

Our fixed rate accounts benefit from 'Our Best Rate Promise', which means if we increase the interest rate for the account you have applied for at any point in the 14 days following the opening of your account, you will automatically receive the higher rate. If we reduce rates don't worry, you will still receive the same rate that you applied for. If our rates do change, you do not need to contact us, we will do everything and then send you confirmation of the new terms applicable to your Fixed Rate Saver or Fixed Rate Cash ISA.
