Do I need an in-home display (IHD) to take part in National Grid DFS events?

You do not need an in-home display to take part.

As long as you have a connected smart meter and half-hourly readings enabled you can take part. We will need to verify your address matches the address linked to your smart meter but you can do that without your IHD.

You can learn more about verifying your address and the options available here.

Please note: Your in-home display (IHD) is different to your smart meter. Your IHD is the little screen that sits on a shelf in your house and displays your energy usage info.
