Just as an add-on. The difference between the monitor we got in argos and the cheaper ones in maplin are that the one in argos gives an energy usage for the whole house, whereas the ones that you plug the appliance into, only give a reading for that appliance. we found it really useful to know what effect lights, and heating etc that are not socket based, but actually use most electricity, were having on our energy usage. Things like leaving lights on, having heating turned up too high and leaving tvs etc on really add on to your bill. The monitor in argos shows at what cost per hour the house is running, so if it seems higher than normal, it prompts a scout around to find out what was left on!! We find it really useful.
Have just checked argos online and the monitor is now selling at 48.79 (considerably cheaper than last year!!).
