Re: I had a smart meter fitted last week
"But you don't need a smart meter to do this. Fit a clamp and display and you can get all this for a few quid. Nothing like the money required for smart metering. Lots of them can even work out the pounds as well as giving an energy figure."
Many local libraries will lend you one for free for a month, by which time the novelty of saving the cost of half a Mars bar a year by turning the loo light off more promptly will have worn off, job done,
