not very loud, but loud enough to hear from inside the car. When i try to listen to it from around the engine bay it doesnt sound like its coming from the fan belt. It sounds like metal rubbing against metal.
As i said, as soon as the oil light goes out (i dont have a pressure guage and it goes out almost instantly) the noise wont appear again. If it were the belt i would assume that it would happen intermittantly and more often.

undo the fan belt and give the alternator & water pump a spin by hand
I will double check and retiighten the fan belt, water pump is new when motor was put together, and alternator is second hand 65A from brickworx. So it "may" be the alternator.
