After I flush and the cistern starts to refill, there is a loud noise, like a vibrating sound, coming from the plastic pipe within the cistern that refills the tank. Any possible (easy) way to cure this.
Many thanks.

Replace the diaphragm in the fill system, I had same problem. It turned out that the diaphragm was worn, and was causing the water to vibrate through the sticking diaphragm. It cost me 12p for a new diaphragm, best 12p I ever spent for the peace and quiet at night.

It sounds like you have water hammer from the water coming through a partially opened valve. Make sure that all valves in the system are turned fullyopen and then 1/2 a trun back. The reason for the 1/2 turn back is to prevent the valve sticking fully open so that when you try to move it - perhaps to *open* it - you try to turn the valve and jamb it even tighter. You then don't know if the valve is stuck open or stuck closed.

Yes the easy way is to stop flushing
