The TV set is unlikely to take more than a couple of watts when "Switched off using the remote control" (we still run an old Panasonic CRT telly which draws only a couple of watts in that state). The 'standby' consumption of a lot of STBs can be virtually unchanged from its active state and you could be taliking of a figure of from 10 to
25 watt standby with perhaps just another 2 to 5 watts when active.If your wallwart phone chargers are of the lightweight smpsu type, You can forget about them. Their standby not charging consumption is typically a 1/4 watt or less for any such chargers sold during the past half decade or so.
If you buy a plug in 'energy monitor' you can test this for yourself anyway (although most digital monitors struggle to show a valid reading for loads less than half a watt - you can plug a whole bunch into an extension lead and test them four or 6 at a time (if you have that many!) to get a more accurate assessment).
A plug in energy monitor will give you a chance to check the weekly total consumption of things like fridges / freezers (any white goods items that are run on an intermittent weekly basis). That should give you a good idea of which items are true 'energy hogs' worthy of replacement with more efficient models and which ones to leave well alone on account of their very low consumption (i.e. don't waste your own energy and wear and tear on the socket switch for things like permanently plugged in phone chargers if, at best, it's only going to shave 25 pence off the annual electricity bill per such charger.
Prioritise: make sure there isn't a 'phantom load', make sure the meter's not over-reading, then deal with your energy hogs (remember to 'fry the biggest fish first before considering the tiddlers :-)
