What is a smart meter?

A smart meter is the next generation of meter for both electricity and gas replacing standard meters.

The old standard meters require customers to track their own meter readings and submit them to the supplier to ensure accurate bills.

Instead, smart meters use a secure network called DCC to communicate your actual meter readings and energy usage automatically and wirelessly to your supplier.

How does a smart meter communicate information?

Smart meters measure how much gas and electricity you use and then sends this data wirelessly to your in-home display.

The meters then transmit this data to the DCC and then it sends this information to your energy company and energy network,

Energy networks manage the wires and pipes which distribute gas and electricity, and use the data to improve their systems.

Energy companies show how you are using energy in your online account and app.
