Re: Retrofit 4G?
For those of us old enough to remember the U.K. switching to “Natural Gas” (from coal gas), the smart meter roll out should have been handled in the same way. Whole streets done on the same day. No opting in or out. Not quite the same safety imperative as having the wrong burners in your boiler/oven/fire I grant you, but it would be done long since by now.
Over here in Ireland smart meters are just getting installed as each meter is due for replacement.
