Every time I turn the cold tap on in out upstairs bathroom, the water come out then CLONK and it stops. Turn the tap on again and it CLONKS again. After a couple of times it works normally.
What is happening and how can I sort it?
I've tried turn the isolater in the pipe to reudce the flow, but it still does it.

airlock? try opening all the taps in the house and running them for a few minutes.

Sounds like an airlock somewhere. Not sure of the real solution but I would start with all taps running at same time for at least five minutes then turn off from nearest to stopcock. Good luck.

Ees pigion in water tank ? Oww he get there ? Oink oink !

Apologies to Manuel.

Go with Matthews' idea. Possibly ending with leaving the offending tap on full to ensure it is flushed.

Check for a high point in the pipe run if possible too.

incorrect pipe sizing can cause clonking in some circumstance I think.
