It seems that the various suppliers fit different ones and, if you
change supplier, the 'old' smart meter is likely to be incompatible with

understand it the 'remote display' can stop functioning.






I had to phone EDF yesterday to cancel the appointment they had made for
me (_again_) to come and fit a smart meter, in spite of being told
repeatedly that I would contact them when I was ready. Whilst there, I
asked about this and (FWIW) they confirmed that these are first
generation meters that revert to dumb if the supplier changes, and that
the second generation ones would be out 'sometime next year'.
