Do note though, smart meters aren't all they are cracked up to be, according to reports there are currently ~4 million new series 2 (SMET2) types that don't work properly or at all.
Many, most, all of the problems will be simple ones, such as failure to communicate readings back to base, in home displays strugling to work, and just the displays failing to show readings - though the meters still report. Complete failures of the meters, where no readings are possible, are quite rare.
