The reason I don’t want a smart meter is due to something I was told a while ago. Apparently they will in future charge different amounts for using gas/elec at different times of day, so without a smart meter they can’t know when I’m using gas/elec, only the amount I’ve used. Though I suppose they could argue that they will therefore charge me the top rate as they can’t discern when I am using gas/elec, but that’s another future argument. What I was told might be rubbish though, as might be what I’ve written!
