We base your direct debit on your annual energy usage figures. We take these figures alongside the cheapest rates we find and use them to calculate your monthly direct debit.
In other words, rates are the key to your energy bill – whereas your direct debit can go up or down based on how much energy you are using.
If your direct debit appears a little higher than usual this could be because we do not have your usage figures.
(It is also good to know that if your energy account goes into credit, you can ask your supplier to lower your direct debit and refund any credit)
