You can cancel your Smart ISA without charge within the first 14 days of opening it. The 14-day cancellation period starts when you initially open a Smart ISA — not when you open an individual pot.

To cancel your Smart ISA, head to your Smart Savings Hub and click Manage in the top right corner. From there, click Account information, Smart ISA details and Close my Smart ISA.

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