When you get a smart meter you’ll start to see your energy differently. They enable you to monitor what you are using – and wasting – in near real time. You can identify the gadgets that guzzle power on your In-Home Display’s (IHD) traffic light system. Switching all your appliances on would move the dial to red, moving back into amber as some are switched off, through to green when everything is off.


It will encourage everyone in your household to adopt good energy habits. You can set energy saving goals and budgets because the IHD has an area that shows what you’re using in pounds and pence. You can even set an hourly rate that as a household you’re happy with, and your IHD will help you stick to that.

Find out how people are using their smart meters to save energy every day.

Manual readings will become a thing of the past as smart meters are self-reading. Your meter will send all the details of your energy usage directly to your supplier.


If you have a pre-pay meter you can simply top up on your mobile and your IHD will display when you’re nearly out of credit. There’s also an emergency credit button you can press if you need a bit of extra time before you are able to top up, say if you are waiting for funds to clear.


Can I switch tariff or energy supplier if I have a smart meter?

Yes. People with a smart meter can switch energy supplier and tariff in exactly the same way that anyone with a traditional meter can. Find out more about switching supplier with a smart meter here.

What's the link between smart meters and clean air?

From the moment your smart meter is installed, you are helping to reduce our carbon emissions as a nation. Smart meters help to create a smart energy system. With a truly smart energy system we can better match supply with demand, and integrate more renewable energy sources such as wind and solar into the system. These forms of generating energy create less air pollution and emit significantly less CO2 into the atmosphere.
