@APJTaylor
it avoids the faff of reading it and results in accurate bills.
Well to be fair, reading my meter 3 times a year and giving my supplier the readings, DOES take 3 and a half minutes of my year.
SO yeah, maybe I will change my mind and get a smart meter after all....
That will free up all that time in my year then to, ....oh maybe boil an egg!
1..... I am being sarcastic. 
2..... Traditional meters ALSO give accurate readings. 
@kalapattar
The adverts seem to be trying to persuade people that
a) Meter reading is a faff
b) You can get power under control
c) You can see how much power you use and use less
Well EXACTLY. It's a load of utter shite. All this can be done with regular traditional meters. There are some seriously brainwashed and naive people on this thread.
I shall not be getting a smart meter EVER, despite 3 and a half minutes of my life being wasted EVERY YEAR on reading the meters and giving it to my energy supplier! 
Keep on peddling all the hyperbole and guff about how much better smart meters supposedly are. You're wasting your time, because I know they don't improve anyone's life or save them any time. Indeed, I have heard a LOAD of stories of people having nothing but trouble with them.
I just wish that my energy supplier would quit trying to palm them off onto me with shitty spam letters saying 'we are ready to install your smart meters.'
NO. I don't WANT them. So fuck off.
