Just out of interest . . . no-one has physically read our non-smart meter for well over two years.
The last time someone arrived to read the meter, they did not have a password, so my wife quite correctly would not let them in. No one has been near us since, despite two changes of supplier in that time. We submit the readings online and the bill is paid by direct debit.
I personally do not see any advantage in having a "smart meter". It will make absolutely no difference whatsoever to our consumption. What we are not using is switched off and that includes things like TVs and so on that are not left on standby when we are not using them.
