I watched that, it was especially frightening to see that the 3 boys spending only 4 hours a day on computers, xbox's etc used £300+ of leccygogo a year.
I have 3 kids spending between 6-9 hours a day.
I want a meter or 3
(I wonder if I can get hold of some freebie ordinary leccy meters & wire them up, one for each kids bedroom lol).
