You can cancel your Smart ISA without charge within the first 14 days of opening it. The 14-day cancellation period starts when the Smart ISA is opened, not when individual ISA pots are opened. Opening an Access or Fixed Term ISA pot doesn’t start a new cancellation period.  

To cancel your Smart ISA, head to the Manage section in the app and select Close cash ISA.  

If you want to close your Smart ISA after your 14-day cancellation period is over, you can find more details here.
