Most TV's left on standby use about 80% of the power as when they are turned on.... I will be costing you a lot!! When I don't have my heating on my leccy bill does not even average £50 a month. When I am not there the only things left on are the water tank (It's actually economically better to leave it on as all it does is click on for a while to keep the temp up rather than heating a whole tank from cold), and of course the fridge freezer. Really think about it mate, and you would be amazed what can be switched off. Video player, DVD player, Sky Box, Broadband router, Microwave, Oven, mobile phone charger, even a 4 way gang lead which has a little light in it.... Switching them off at the power could save you literally hundreds a year.
