What is a smart meter?

Smart meters replace your existing gas and electricity meters and tell you more about the energy you use in your home. They send regular meter readings automatically to your supplier. This keeps your energy use up-to-date.

Once you've had your smart meter installed, you'll be able to see how much energy you're using:

  • On an In-Home Display.
  • By logging into an online account.
  • In an app.

Are smart meters free?

Yes. There is no up-front cost to install a smart meter.

What is an In-Home Display?

The In-Home Display is a handy digital device that sits on your desk or kitchen worktop and communicates with your smart meter. It's a kind of partnership – a smart, secure one.

The In-Home Display loves being close to your smart meter to keep a strong connection. They can then keep you up-to-date about the energy you’re using.

What does a smart meter look like?

You've probably heard and read a lot about smart meters, but you might not actually know what they look like or how big a smart meter is.

When you have your gas and/or electricity energy meter replaced, you'll get a smart meter that looks similar to your old one.

Some people mistake the In-Home Display for a smart meter, but they’re separate devices. In-Home Displays have a large touch screen and communicate with your smart meter to give you an idea of the energy you're using.

Types of smart meter

SMETS1 – 1st generation smart meters

The first smart meters to be installed. If you switched supplier with this smart meter it’s unlikely the new supplier would have received anything sent over its 3G network so the smart meter probably became “dumb” like a basic meter. However as part of an industry-wide programme, they'll soon work the same way as 2nd generation smart meters (SMETS2).

SMETS2 – 2nd generation smart meters

These are the smart meters that are being installed across the country right now. Information is shared in the same way across SMETS2 smart meters which means you can carry all the benefits of smart over when you switch suppliers.

How do smart meters work?

Smart meters use two networks to communicate within your home and with your energy supplier:

  • The Home Area Network (HAN)
  • The Wide Area Network (WAN)

The HAN is a secure network that links your gas and electricity meters together. It also enables your meters and In-Home Display to communicate with one another.

The WAN is similar to a mobile network. Smart meters use the WAN to send energy suppliers data about the energy you use. This helps you get accurate bills.

Do smart meters need Wi-Fi to work?

Smart meters use their own secure wireless networks to “talk” to your In-Home Display and to your supplier. So there’s no internet connection and smart meters don’t use Wi-Fi.

Important information

Will I still get bills for gas and electricity with my smart meter?

You'll still receive regular bills as you do now, either online or by post. The difference is that smart meters send us regular, accurate meter readings, so you shouldn't receive any more estimated bills.

Are there any regulatory requirements for smart meters?

We’re committed to keeping your personal information safe. Our Smart Meter Data Charter sets out the standards you can expect from us when we ask for and store your personal information. What's more, smart meters work on separate, secure networks.

We're a signatory of the Smart Metering Installation Code of Practice. This means you can be sure you'll receive a high standard of service from us throughout the installation process and that you know how to use, and benefit from, your smart meter to help improve the energy efficiency of your home.

Smart meters send us readings automatically

We rely on a mobile phone or wireless signal to get your smart meter readings. If these fail, you'll either need to take your own reading and send it to us, or your bills will be estimated.
