A Direct Debit can only be set up by the organisation to which you're making the payment. Normally, you sign a mandate that gives the company permission to take funds from your account in an agreed way - like a monthly gym membership or your mobile phone bill. It normally confirms who's receiving the payment, the account to be debited, the amount and the dates of the payment. You‘re protected under the Direct Debit Guarantee scheme so that any amount debited in error is refunded immediately.
