A method of determining a charge in respect to consumption of electricity supplied from an electricity distribution network and priced in successive sub-periods,the network incorporating a closure having one or more input supply connections all of which are metered and output connections including at least one metered output,the method comprising:

  • using information derived from the metered inputs to the closure to determine a profile indicating the variation in the quantity of electricity supplied to the closure over the sub-periods;

    metering each metered output to determine the quantity of electricity taken by that output over a metered period, longer than each sub-period, for that output;

    determining an apportionment of metered consumption between the sub-periods in dependence on the profile; and

    determining a charge for the consumption in dependence on the quantities of metered consumption and the apportionment.
