Smart meter Ireland

Smart Meter Ireland Guide

A smart meter records electricity usage more frequently and can support time of use tariffs. Getting one installed does not automatically mean your tariff changes.

What a smart meter does

Smart meters are installed by ESB Networks as part of the national rollout. They can send meter readings remotely and support better visibility of your usage.

A smart meter can also enable time of use tariffs, where the price changes by time band. The common idea is to encourage usage away from expensive peak periods.

A smart meter is not the same as a smart tariff

Having the meter does not automatically change your tariff. Any tariff change is agreed between you and your electricity supplier.

Before choosing a smart tariff, compare day, night, and peak rates against your actual routine. A smart plan is only cheaper if your usage pattern fits the cheaper windows.

Important: Do not switch to a smart tariff just because the lowest advertised night rate looks attractive. Check the peak rate too.

Using smart meter data

Smart meter data can make comparisons more accurate because it shows when electricity is used, not only how much is used overall.

That helps answer practical questions, such as whether an EV tariff, night saver tariff, weekend tariff, or standard tariff is likely to cost less.

The Sortd angle

Sortd can use the smart meter question as part of a wider plan watch. Once your tariff type and renewal date are saved, the important thing is reviewing whether the plan still matches your real usage.
