Hi, I have just had a smart meter installed and can only use the meter when it is plugged in. There is no battery sign showing next to the time in the top right-hand corner.  If I unplug the lead from the meter the screen goes blank.  Do I need a new IHD please?

Thanks.

Hi @Sheila59 and welcome to this customer forum. The IHD isn’t designed to be off power for long and so is probably fine (depending on which one you have).
You should leave it somewhere plugged in. I leave mine for example in the kitchen where several high use appliances are and I can check easily
