It was so very easy, much easier than UK high street bank operations to open an account. And I thought it just lovely that Primrose rang and introduced herself, before I made my decisions.

Very intuitive platform. Like the idea that you can spread risk by keeping investments below the FSCS limits and this platform makes it easier to do that.

Castle Trust Bank
Castle Trust Bank
I have an existing account and was informed that the interest rate will reduce from 3.61% to 3.22% as of 1 Jun 2026.
I moved my savings to my holding account and today was able to re-deposit them.
On selecting the best high interest instant access account I was surprised to see Castle Trust Bank offering 3.7%.
This is higher than the original. I'm sure there's been a mistake but I have all the correspondence to prove the communication.

Thank you for sharing your recent experience with us. We understand you have spoken to our Client Services team in relation to this which we hope helped.
The rate change you experienced was due to Castle Trust Bank launching a new issue of their Instant Access product (3.7% AER) on 27 May 2026. As this is a new product issue, the updated rate doesn’t apply to existing accounts, which is at the discretion of our partner banks' if they wish to increase rates on existing products or not. Unfortunately they didn't on this occasion.
We understand this can be frustrating, but we’re pleased you were able to open the new account straight away using our recent platform improvements.
If you need any further help, we’re here to assist - do reach out to our Client Services Team.
Best regards,
