If you dont want a smart meter be sure not to let Activo into your house. My analog meter was playing up, so I contacted Scottish power for a replacement, making it absolutly clear that I did not want a smart meter. The girl on the phone assured me that the meter would be replaced by a analog meter, but when the installer turned up , unfortunately I could not be there and he fitted a smart meter without asking my wife if it was OK. I have made a complaint and asked for the smart meter to be removed.
