I still don't have one
I'd have to take at least half a day off work to get one fitted as it's in our front hall. I don't see the benefit and my leccy supplier has twice lied to me about it being "compulsory by the end of the year" which just got my back up.
Until I hear of evidenced benefits to customers I'm not interested. Like many I was given a power meter that connects to my existing supply so I could monitor use anyway, as far as I can see all the new one does is allow local meter readers to be laid off and I doubt that saving will be passed on.
I can see my meter readings online, I don't need to see them updated 24/7 though.
