A kilowhat hour is the the ammount of electricity a one kilowhat electrical appliance uses in one hour and is the standard method for charging for electricity. EG a 1KW electrical heater left on for 2 hours at a rate of 10pence per KWH will cost 20p.

I consume average 1.5 kw per hour! I am being charged £170.00per month by EDF! Is this a reasonable charge? add a comment
