No - you don't! You can schedule a transfer in the app.

If you are transferring into a Cash ISA - Easy access, you can now schedule a transfer in the app to complete on your maturity date. To do this initiate a transfer in app and answer 'yes' to the question 'Is your ISA locked into a fixed term?' and enter your maturity date.

We will contact your provider 4 weeks before (or sooner) your maturity date.
