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... See more

Thank you for taking the time leave a review and we’re sorry you don’t feel you have been kept informed of the progress of your ISA transfer.

We send an email the day after the account is opened to help set expectations on how long the process might take and send confirmation once the transfer has been successfully completed.

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.

Thank you for taking the time to share your experience.

We understand your disappointment in missing the 5th April deadline to deposit funds into the 2025/2026 tax year.

The Welcome Email, sent once the account is opened, contains all the details on how to deposit into the new account.

We also updated our website and our IVR telephony messaging to set expectations regarding the deadline for funds to be received for inclusion in the 2025/2026 tax year.

We appreciate your feedback and hope this explanation provides clarity.

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.
