I have a portable air conditioning unit that is rated at 1200 watts.

My last electricity bill has the following:

76 kWh at 12.420p
236 KWh at 9.010p

So I reckon I can take the second figure as this is what most of my
electricity is charged at.

So does a unit rated 1200 watts use 1.2KWh, if so then the air
conditioner would cost me:

9.10 x 1.2 = 10.81p


Is this right?

Per hour yes, but only assuming it ran flat out for the entire hour.
Usually the 1200 watts will be the maximum rating, rather than the
average KWh of normal use where the compressor will switch on and off
dependent on need for cooling.

Also check that the 1200 watts refers to the power input to the a/c not the
heat pumping capacity of the unit.

If it's a portable unit it's unlikely to have a compressor?

Mine does. And damn heavy it is too ;-)

Its an air conditioner not some toy based on a peltier effect device.
