My mum has had a smart meter for electricity for some time now. The first was fitted under her previous supplier and the plug-in display had a "traffic light" indicator to show consumption as well as the detailed figures.
It took her new supplier a year to provide a replacement, prompted only by a refusal to provide our own readings, pointing out that all smart meters can be read remotely.
The new plug-in only has an LCD display (no backlight), so gives no hint of usage unless you examine it very carefully.
So the only benefit to her is the remote reading.
As to gas, the last accurate reading is now over four years ago, because the battery for the little digital display ran out. It seems that there is no current model of gas meter, smart or not, which will fit in the same space as the old one.
A complaint to the Ombudsman has prompted yet another engineer visit this coming Monday. Well into double figures now. I suggested that they remove the existing meter and refurbish it. I also suggested that while it was in the workshop they could determine the correct reading and adjust four years' worth of estimated bills appropriately. Knowing what I do about the internals of meters, it is extremely unlikely that they can actually read it, but appearing "reasonable" usually gets you a better outcome.
