The account was very easy to open. The transfer went very smoothly with Castle Trust Bank keeping me informed at each stage. The transfer was also the quickest and most efficient of any I have done.

First class transfer from previous provider

First class transfer of ISA from previous provider. Completed in just a 2-3 days. In my experience with other companies it takes weeks of stress and chasing. Castle completed the transfer without me having any stress or inconvenience.

The onboarding process was smooth

The onboarding process was smooth, however every time I log into castle trust for the first time (irrespective of using my WiFi or phone network) I am presented with an error. Once I log out and back in I am able to see my account. This has happened at least 4/5 times now.

Quick to set up…

Very easy to set up the accounts online, spoke to a chap on the phone who was who was very informative and answered all my questions. My 3 star rating is because having to make several payments in there was no conformation to confirm they were received,
I have never experienced this with other Banks.
