What is a Smart Meter and How Does It Work?

Understanding Smart Meters

A smart meter is a modern digital device that takes the place of old gas and electricity meters in Great Britain. Unlike traditional meters that need manual meter readings, smart meters send exact energy usage information to your energy supplier automatically. They do this through a safe national network known as the Data Communications Company (DCC).

Smart meters send data to your energy supplier through a safe wireless network that is different from your home Wi-Fi. This network is run by the DCC, which makes sure the data is sent securely and without problems. A smart meter also includes an in-home display (IHD) that shows real-time details about your energy usage and costs.

Fact: By 2024, more than 30 million smart meters will be set up in homes and small businesses in the UK. This information comes from the Department for Energy Security and Net Zero (DESNZ).
