Constant high pitch hum/ whistle through house.

Even when the heating is off, there seems to be a constant hum/whistling sound through the house. Seems to be louder up stairs. Cant pin point it though. Have recently changed ball cock in cold water tank in the loft. Seemed to have started after that.

I think you have indetified the fault to be within the replacement ball cock.

I remenber one job where we had to try four different manufacurers before the problem was sorted !

You could always try fitting a Torbeck, valve into the tank, these are sometimes refered to Quiet valves, they are a good product and come with a resticor piece that you can slot in to reduce the pressure to suit.
