In a normal month without any heating my electricity bill is about £70 per month. I use the washer, dryer if the weather is rubbish and dishwasher during the off peak times @11p per KW. 
I can only therefore assume that this amount is for general lights and sockets and the 10 hours off peak my water is heated. I don't have a shower and no boost buttons. 
My question is about whether I should (and is it possible to) put a timer on the water cylinder. Does the cylinder use electric all the time during the  off peak or just switches on and off to get it to the required temp ... like a top up? 
Apart from and sink of water in the morning, the 5 hours I get of off peak water heating at night, has no other use... can I have a timer that uses just 2 hours of this and would that he enough to warm the water tank up?  The afternoon 3 hours is useful for warm water when we get home at tea time, but could this be reduced to sat 1.5 hours on a timer, and the evening water 2 hours is very useful for baths etc.

Hi, just as a short-term measure, can I ask:  does the water come out of the taps very hot?  If so you should be able to reduce the temperature that the thermostat in the immersion heater is set to.  (Shouldn't be set below 50 degrees, though.)

By limiting the time that the tank heats for as you propose, you are basically limiting the temperaure that the water would get to, so this adjustment would be a neater/cheaper way to achieve the same thing.
