Frequently Asked Questions

 

There two types of electricity meters - Analog, otherwise known as Basic Meters, and Smart Meters.
Analog meters are the original meters used to measure electricity usage. These meters have a manual dial in them, and some have been replaced by Basic Meters with a digital display. It’s easy to confuse digital Basic Meters with Smart Meters, though Smart Meters are more advanced - Smart Meters can be read remotely in intervals of 15 or 30 minutes, which means that the meter reader doesn’t need to physically come to your address.

Smart meters (and some digital Basic Meters) also allow you to have a Time of Use tariff in your home.

NMI stands for National Meter Identifier. It is a unique number allocated to your electricity meter. The electricity industry uses this number to identify your meter so your power company can bill the correct residential address with the correct meter read. It is 11 digits long and located on your electricity bill – it is not normally written on your meter.
