ESB Networks will include all accounts with a replacement Day Night meter or timeclock in a review process as a matter of course.
Following the resolution of the meter issue, ESB Networks will review the consumption history and assess whether an adjustment to historic consumption is due. If there is an adjustment due, we will analyse historic consumption combined with any other information available to determine a fault period. This produces an initial estimation of consumption based on historic consumption patterns. On occasion it may not be possible to use the historic consumption information to calculate a consumption adjustment. This can arise if there is no obvious equipment failure date. Should this occur, ESB Networks may be required to use consumption data from the new meter and/or timeclock to calculate the adjustment.
However, if no actual reading is received for the new meter and/or timeclock within 4 months of the equipment replacement then a 62:38 ratio (average Day:Night consumption split) is used to calculate the adjustment. The apportionment is informed by the CRU Supplier Handbook.
We will write to the customer where a credit adjustment is calculated as being due to let them know the estimated units that were allocated incorrectly to the Day register. There is no action required on the customers part as we will also issue the initial estimated units to the current registered supplier in line with Rules for the Application of DUos Tariff Group. The supplier should then credit the units to the customer’s account. Any billing queries should be directed to the customers electricity supplier. Where the customer was registered with another supplier/s during the period in question, the full refund will be advised to the current registered supplier. Under Section 11 of the Statute of Limitations Act 1957, any rebate will apply up to a maximum of six years from the date the metering issue is resolved.
The current registered supplier can engage further with ESB Networks on the customers behalf in relation to the initial calculation. The customer, through their supplier, can also provide additional information with regards to consumption patterns which may be taken into consideration by ESB Networks when deriving the adjustment required.
ESB Networks will not process a retrospective adjustment on the account where an additional charge is calculated as being due. However, customers should note that their consumption as recorded by the meter and/or timeclock may increase following the resolution of the meter issue which may result in an increase in bills they receive from their supplier.
All account reviews are completed objectively and informed by the CRU Supplier Handbook. The regulatory model under which ESB Networks operates means that we are indifferent financially to the value of any adjustment calculated.
