Not in my house
I don't trust my energy company at all. I recently got an aggressive letter saying they had been trying to get in touch with me to inspect my gas meter, and if I did not get in touch with them to arrange an appointment within 7 days they would be going to court. I contacted them and asked when and how they had tried to get in touch with me, and it transpired they hadn't: they had sent the wrong letter out.
They try and put my direct debit up every 6 months stating I am paying under consumption, despite the fact I end each six month period in credit.
With all the ways that smart metering could go wrong, they can forget any ideas they have of installing one at my house. I fully expect the same mistakes but with real time 'evidence' to back them up and screw me even more.
