I am fitting 22mm compression stop end to a cold water pipe in my
bathroom and was wondering how far onto the pipe should the
compression ring go? Many thanks.

Put the nut onto the pipe first.
Next slide on the olive (compression ring). At this point you can add
lubricant if you wish.
Put the cap on the end of the pipe until it stops then push up the nut
with
the olive to the cap threads and screw together without lifting the cap.

Thanks Heliotrope, very clear instructions. What sort of lubricant
would i use?

There are plenty of lubricating jointing compounds about in the d i y
sheds, plumbers merchants and the likes of screwfix etc.
The main thing is to be sure they are suitable for use on potable water.
Just a light smear is all that is required to assist with tightening up and
stopping the screeching whilst doing so.
If you are only doing one or two fittings then it would not be worth buying
the stuff and just tighten up dry.
