It's completely free to keep your account open and available for whenever you may need.
If you would like to proceed with closing your account, you won't be able to create a new account again for at least 12 months from the date the account is closed. If you would like to return after this 12 month period, a full review by our accounts team will be required, which may take up to 3 business days.
If you would like to go ahead with this, please fill out our support form here.
There are no hard feelings and we hope to see you again soon!
