I had a smart meter fitted by BG a couple of years ago. Then I swapped to Eon. If I recall correctly I tried the meter after I swapped and it didn't work and I think I phoned eon and they said they would have to fit their own at some undisclosed time in the future. Surely this is madness they should be interchangeable? Looking at the government website it says that smart meters should still work if you change supplier. So was I given the correct information and there is no way a BG meter will work with eon? I tried plugging it in again yesterday and it still doesn't read out energy usage.
