What is an In-Home Display (IHD)?

An In-Home Display, or IHD, is a small electrical device with a touch screen. It works with a smart meter to give you all kinds of data about your energy use.

When you upgrade to a smart meter, whichever plan you’re on, we will offer you an IHD with it.

We’ll deliver the In-Home Display with your smart meter, and our engineer will set it up as well as giving you a demonstration of how it works.

It’s best to keep your IHD plugged into the mains all the time, but you can run it on batteries if there are no sockets in a convenient spot near your smart meter. It takes two AAA batteries – so even if you keep it plugged in, it’s a good idea to have a couple of spare batteries around in case there’s a power cut.

To start with, the screen on your In-Home Display might be blank, because it’s saving energy. Once you’ve switched it on, a main menu will appear with a series of ‘buttons’ that let you move to other screens and read all kinds of information about the amount of energy you’re using and what it costs.

What does the In-Home Display actually do?

For all our OVO Energy plans: the IHD keeps you up to date with how much energy you’re using, what it’s costing you, and how much carbon dioxide (CO2) you’re producing. You can change the screen to show your current use, or your use over the last few hours, days, weeks or months. You can also choose to see how much you’re using in kilowatt hours (kWh), or what it’s costing you.

If you renew with us on a new OVO contract at a different rate, or your rates change for any other reason, we’ll update your IHD remotely to show your new rates. 

You can also use the IHD to set alerts and warnings to help you keep track of your energy use. Or, if you want to limit the daily amount of energy you use, you can set it to warn you when you’re getting close to a level of kWh or cost each day.

If you’re on our smart PAYG Standard service: the IHD will also show a running balance so you always know how much credit you’ve got left, and you can set alerts and warnings to let you know when if your credit’s getting low. These functions aren’t yet available for Smart PAYG+ customers.
