Highly satisfied customer
Been with Castle Trust Bank now for over 2 years. Always a good interest rate on my cash ISA and the app is so easy to use. What more could I ask for.

Best rates, no problem banking.
This bank is great to invest in. They offer the best rates and have a good clear website that is easy to navigate. We transferred some matured ISAs from elswhere without any problems at all. We have also invested with them previously with no problems. I would recommend Castle Trust bank to anyone.

Your ISA Transfer request was pended by your existing Plan Manager until 1st April and funds were received by us on 2nd April. The money was applied on the next working day which, due to the bank holiday weekend, was 7th April and interest was backdated to the day we received the funds.

Moving money on maturity of an ISA
My ISA was maturing and I wanted to split the money up into a 1yr, 2yr and 3yr accounts on maturity. I was unable to do this online and had to open 3 new accounts then phone Castle Trust on the day of maturity. In the event I found that another provider had increased their rates for one of the intended years and so I went with them only to find that the day after phoning CT had increased their rate for that year - had I been informed of the intended increase when phoned I would have left all my money in CT.
Overall I’ve been pleased with CT with reasonable interest rates and the ease of using their app online but the inability to give my maturity instructions online and the fact I was not made aware of the intended change in interest rates - I can only give them 3 stars.

Thank you for taking them to share your experience with us.
We’re sorry we don’t currently offer the functionality for maturity reinvestment instructions to be split across multiple accounts online. However, our friendly team are happy to help with how to do this.
Our interest rates can increase or decrease at short notice particularly in the current environment and colleagues are not given advance notice of when these changes will take place.
