accounting period any change is made as to the amount payable or the manner in
which the charges are made, or by reason of the introduction of a new rate,
charge, fee, rental or other item of account, the energy operator shall adjust
the charges for the relevant period affected by the change by reference to the
date on which the change is to take effect or by reference to the date on
which the change is applied to any applicable account, whichever results in
the lower charge.
