It is possible for us to arrange to change the amount of a Direct Debit if you email us, but this can take two weeks to process. Unfortunately, we cannot change the date of the payment. However, we suggest that the easiest option is for you to either set up an additional Direct Debit (if you are increasing your gift) or simply cancel your Direct Debit and set up a new one. Please contact [email protected] if you need to discuss this further.
