Should I cancel my direct debit?
You are well within your rights to cancel your Direct Debit but you may want to check with your old supplier so it doesn’t have an effect on any final payments or refunds.
Will I get charged twice?
You may find two payments go out to both companies in the first month (don’t worry - you will never pay twice for the same energy) so you may wish to cancel your Direct Debit with your old supplier to avoid this, although if you are in credit they will have to send you a cheque instead of simply depositing back into your account.
