I've only had my smart meter 48 hours. And it's showing I've used £14 electric in 2 days in a one bedroom flat. I am on economy 7 (which supposed to be cheaper at night) but when I go to bed. And then wake up (7 hours sleep) it's showing I've used £5. I switch on the hot water boiler before I go to bed. And turn it off when I get up. Something ain't right somewhere. How can this be cheaper at night. When I'm just using around £2 in the day? I called regarding this. And was told just ignore it. Because it's still taking the reading from the old meter. And it should be ok in a few days. How ridiculous is this for an excuse. I will cancel my direct debit. And NOT pay a penny until this is investigated.
