Can I deposit cash or a cheque into my Biscuit current account?

No – Biscuit doesn't accept cash or cheque deposits.

To add money to your account, use a bank transfer instead – see How do I add money to my account? for how to do this.

If you have cash or a cheque to pay in, deposit it into another bank account first (for example, one that accepts branch or Post Office deposits), then transfer the money across to your Biscuit bank account once it's cleared.
