What is a smart meter and how does it work?

A smart meter is a newer type of electricity or gas meter. All energy suppliers are installing them as a part of an upgrade to the UK's energy system.

Smart meters come with a handy in-home display, called an IHD. Here you can see how much energy you're using and what it costs. The smart meter also sends your meter readings automatically to us so you don't have to. 

There are different types of smart meters, including smart Pay As You Go meters

Why it’s worth getting a smart meter

There are three main benefits to having a smart meter:

1. Complete control

See how much you're spending in real time. This can help you make small changes to reduce your energy usage, as well as your bill.

2. Hassle-free

Your smart meter will send readings automatically(1). This way you'll get more accurate bills without leaving the sofa.

3. Low-carbon lifestyle

Understanding where your energy goes will encourage you to think about your carbon footprint and how to live more sustainably.

Everything you need to know about smart meters

Do I need to pay to have a smart meter installed?

There is no upfront extra cost for the meter, or for the in-home display it comes with.


Do I need to have an internet connection to have a smart meter?

You don't need to have broadband or Wi-Fi internet to have a smart meter. Every smart has its own SIM card. It'll send your meter readings remotely over a safe, dedicated wireless GSM network. 


Is it safe to have a smart meter?

There's no evidence of risk to your health from smart meters. Smart meters we install have been tested to make sure they're safe. They meet and exceed all UK and EU safety standards. Read about smart meter safety.


What happens to my energy data?

The government has put rules in place to protect the data collected from your meter. Your data will help us understand how much energy everyone is using across the country.

How do I read a smart meter?

You won't need to read your smart meter as it'll do that automatically(1). You can choose for it to send your meter readings every 30 minutes, every day or every month.

If you'd like to take a reading, look at the screen on your smart meter. It will show your total volume register, which is measured in cubic meters (m3 ). This is the number we’ll use, including zeros, to work out your bill.

You can give us your meter reading through MyAccount, via our mobile phone app or by calling our automated line on 0333 200 5108(2).


Can I get a top-up smart meter?

If you already have a pre-payment meter you may be able to get a Pay As You Go smart meter.


Can I switch to EDF if I already have a smart meter?

You can switch to EDF if you already have a smart meter. 

If you have a newer smart meter, called SMETS2, we should be able to take your meter readings automatically. We're gradually updating SMETS1 meters, so they'll have the same functionality as SMETS2 smart meters.
