Pleasant experience

Offer better rate compared to other providers. Staff are very helpful in explaining and resolving issues. Definitely would recommend if continues to offer good rates

Poor Customer Service experience

I initially had problems transferring £20k into the account for the '25 to '26 tax year, I tried again with £1 which worked successfully, however when I then tried to transfer the remainder it was delayed and was then transferred into the '26 to '27 tax year. Your customer services told me there was nothing they could do even though HMRC provides mechanisms to "repair" ISAs. I will now have to pay tax on the interest from a lump sum payment which will have to go into an ordinary savings account.

Extremely smooth on-line process

The whole on-line process from application to initial funding and transfer of an existing ISA went through smoothly and quickly. I rang Castle Trust with a query regarding the interest rate on my ISA. I quickly got through to a helpful member of staff who answered my query clearly and professionally
