Thanks for that information , I note that an Electric Company does not have a legal right to change meter as they have said in an Email to me , they can only legally change the meter if damaged, and I still have the option of having the wi fi turned off .[ I live in a rural area where mobile phones do not work ]which links to https://www.which.co.uk/news/article/the-truth-behind-smart-meter-myths-aoJeW4L7Fwmj
That article has no mention of any type of disconnection. The word "disconnect" does not appear in the article.
It does say that remote access to the meter is possible to remotely "repair" issues
""if it can't resolve the issue remotely, it should send someone round to inspect it for you""
