All the normal Direct Debit safeguards and guarantees apply. No changes in the amount, date, and frequency to be debited can be made without notifying you at least ten working days in advance of your account being debited. In the event of any error, you’re entitled to an immediate refund from your Bank or Building Society. You have the right to cancel a Direct Debit instruction any time simply by writing to your Bank or Building Society, with a copy to us.
