SInce we had a water softener fitted, a number of the Yorkshire
compression fittings have a greenish dust emanating from them.

Is this just a matter of nipping up the nuts a little or would it be a
sign of something more serious?

Confusing, I'm afraid.
Yorkshire fittings to me are soldered fittings with a ring of solder
included in a ridge around the fitting.
Not the same as compression fittings which have nuts and olives.

Green dust sounds like a water leak that has dried up.

Water softeners seem to do strange things to aluminium (such as rivets in
knife handles) but I haven't heard of them attacking copper or brass.
