Some customer notice an increase in the value of their bills following a meter replacement. This increase in billing amount can be driven by either or both of the following factors:
Meter replacement following long-term-no-access
If ESB Networks or Gas Networks Ireland are unable to access your meter for an extended period you will receive bills based on estimated readings. If your meter is replaced an actual read will be taken from your old meter as it is being removed. If the actual read is higher than had been estimated the balance will be reflected on your next bill.
Faulty legacy meter
Occasionally meters become defective due to damage or old age and fail to record usage correctly. When a defective meter is replaced you may see an increase in the usage recorded on your bill even though your usage has remained the same. This is because the new meter is actually recording your usage more accurately.
