Your Monthly Direct Debit is reviewed at least once a year.

When we do the review, if we think you're paying too much, or not enough, for the amount of energy you've used and what you're likely to use in the future then we'll adjust your Monthly Direct Debit accordingly.

We'll let you know about this in your letter via post or e-letter and we'll give you at least 10 working days’ notice of the change.
