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.
