Following any month in which your bill is estimated, your account balance is always brought up-to-date on your next service bill, based on your actual energy use.

What part of my bill can I choose another energy supplier for? You can choose another energy supplier for the Supplier Services area of your bill. All our customers have the choice of who supplies their energy. Even if you choose another energy supplier, we will continue to bill you for your Delivery Service.
