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.
Without being rude to your wife, how difficult is it to realise that energy costs money, therefore if you want to save money use less? Don't turn heating on, wear more clothes. Don't leave lights on when not required. etc.etc. It's hardly rocket science and a meter/display is hardly required.
The government could massively reduce the cost by simply sending every customer two pieces of equipment. The first would be a clamp and display. The second would be a plug through energy meter so you can measure individual appliances (you could turn them on and off and watch the clamp meter mind). Total cost maybe £50 max for each household. A hell of a lot cheaper than the £13-19b they're predicting for smart metering.
