Will the billing rates remain fixed on the bill for the whole year?

Billing rates can be fixed for the whole year by procuring the energy for the whole year ahead of delivery.

Billing rates can also be fixed by setting a reference price at the beginning of the flexible energy procurement contract and then reconciled after a certain period of time, in line with trades done during the delivery period.

Alternatively, energy users can let their energy unit rates change in line with the actioned trades, which may or may not alter throughout the year.
