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

      No, 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.

      Kettle and smart meter V2

      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.
