IBERDROLA ARE writing to inform their customers that they are currently replacing electricity meters with smart meters. This is part of a ministerial order to replace the traditional electric meters with state of the art electricity measuring equipment.
Properties on a low tariff, such as 3.3 kW or 3.45 kW or lower, may experience power cuts after the smart meter is fitted due to overloading the ICP, that means tripping out when too many electrical appliances are switch on at the same time. In some cases this involves a trip to the meter cupboard to reset the power control switch (ICP). A smart meter limits the consumer to the amount on their contract. This amount is stated on your electricity bill. Check yours to see the amount is sufficient.
Properties with illegal upgrades will be reduced back to their original state once a smart meter is fitted. An illegal upgrade is one where a boletin was not issued by the installer, and a new contract was never arranged with Iberdrola.
