How do smart meters work?

A smart meter replaces your current electricity meter to measure how much gas and electricity your business is using, as well as what it's costing you. This information then appears on your smart meter display in near-real time.

What makes your smart meter “smart” is that it sends us this information automatically, either half hourly, daily or monthly, depending on what you agree to share with us. This means we can always send you accurate bills instead of estimated ones. It also means you'll no longer have to supply us with meter readings so you can get on with running your business.

All information we receive from your smart meter is completely secure and we won't share it with anyone without your permission. To find out more about the benefits of smart meters and how they're about to transform the way we look at energy, see how smart meters can benefit you.

When will smart meters be available in my area?

As the technology develops we’ll be able to support smart metering in more and more areas around the country, and by 2020 all homes and businesses in Great Britain will have one fitted.

At the moment, we’re only able to offer smart meters in certain areas, with the right amount of signal and for certain meter types. As this grows we’ll be contacting all our customers to arrange installations.

How can I use my smart meter to save on energy

We’re currently developing an online tool that will help you keep track of your energy habits and help you see where you can save. If you’ve chosen to send us half-hourly readings, you’ll be able to see when in the day your usage has been particularly high or low, so you’ll know what is costing you more energy.

Will I always get accurate bills?

Your smart meter calculates how much energy you’re using, what this costs over time and the cost every hour as you’re using it. It then automatically send us all this information. This means you’ll no longer receive estimated bills, so you’ll only pay for the energy you use. Only in very rare cases, the smart meter may not be able to send us an automated meter reading due to a connectivity loss or a commissioning error. If this happens, we’ll try to contact you for a manual meter reading (you can see how to read your new meter in this guide). If we don’t manage to obtain it from you, we’ll send you an estimated bill.
