I would like to have a variable direct debit instead of the amount that I pay now. I’ve been told that I’m a trusted user by Bulb. I send a reading from my meters regardless of your readings every month 2 days before my bill. How would that affect my healthy credit ? Would you use that up first?
I have taken a look at your account and we can move you to a variable direct debit if you wish. With this, your DD stays active and after each monthly statement we take a payment for the owed amount within 14 days.
If you have excess credit on the account when we change the payments this gets used up before a payment is taken.
Please let me know if you would like us to update your payments to a variable direct debit.
