Castle Trust Bank Reviews 

Everything went smoothly as we had hoped, I did have to speak to customer services during the application to clear up a discrepancy, but the phone was answered quickly and the advisor was soon able to confirm how to complete the application for the transfer.

Good rate. Easy to set the account up, and customer service was good when I had a problem logging in, due to forgetting my password.

Recently this bank came up on a search for best 5 year fixed rate cash ISA. Never heard of them before but the reviews were generally positive and also had the FSCS protection. Decided to open a new 5 Year fixed rate cash ISA for my wife on 8th June 2026 since her present ISA was due to mature with another provider. With the present uncertainty in the political world, fixing at a decent rate made 100% sense for our needs.

I have to say the process was flawless after having spoken to customer services first to ensure what was being planned was actually possible with an ISA transfer also to follow. The ISA was opened without any issues and the follow up communication was excellent. Once an account was opened the format and ease of navigating between the different sub-menus was straightforward. On this evidence, I will use them for my own ISA later in the year if the rate is good.

In summary, not yet a household name but I would not hesitate to recommend this bank for a savings account "Great trees grow from small seeds".

The transfer from my existing CT ISA was completed very quickly as was the introduction of new money. Immensely impressed by Customer Service.
Would thoroughly recommend CT to friends & family

I always get the good and correct Service. And I don’t have to wait for a long time on the phone.
Your staff are well trained and motivated to help the customers.

Transfer of funds to a new savings account was an easy process, via the portal.

It was my first experience of opening an online
savings account and with my poor hearing it was difficult for me, at times, to follow the instructions that I was being given over the telephone but your
member of staff but she was very kind and patient and
I appreciated that very much

Very easy to communicate over the phone with a real person!

Excellent service on the phone and help with online queries.

I found Castle Trust easy to deal with, both in the initial online account set-up for a Fixed Term Cash ISA, and in speaking to them directly when I had a query. Their App is straightforward. I was particularly pleased with the available Rate and that they are protected by the FSCS scheme.

Always find your staff most helpfull, please keep up the good work.

It was great as I managed to extend it when I was not in the country.
However I extended 2 days later then the renewal date and I feel that I can't start the same date when it's expired. It's a let down.

I had not held a savings account with Castle Trust before but found opening the account on line very straightforward and I received helpful and timely communications about my account. I was also pleased with my competitive interest rate on my chosen fixed rate account

Great interest rate and a smooth isa transfer

I recently opened a 5 year cash ISA with CTB and transferred in a Virgin Money maturing ISA. The set up was simplicity itself, and I love the communication from CTB; they send a text to tell you that they have messaged you which is perfect. The transfer itself was made the day after my Virgin Money ISA matured so you can't ask for more than that (apart from the interest rate, which was great). Thoroughly recommended.

Applying online for a new fixed term isa account was straightforward. Then 14 days to fund account seemed reasonable.

The advert was clear and when I need help the person on the phone was very helpful
The rate on offer is excellent
