I have a cold mains in that is a black flexible rubber looking pipe. Please see photo 1. It is currently connected to a 22mm stopcock.



I’d like to send it 90 deg to the right. This is so I can lower the shelf above it and have the mains come in at a more convenient place. See photo 2 (with annotations).



What’s the best way to connect to this mains pipe? Are there any issues with this plan?

22mm compression elbow and a 3/4 imperial Olive
 
Almost certainly 1/2 in black alkathene.
If you want to shorten it down 22mm compression fittings with a 3/4 olive works well . You will need to reuse pipe stiffener/insert from existing fitting.
So a 2mm compression elbow with 3/4 olive then reduced to 15,mm and a new stop tap.
 
But go steady this can be brittle and snap on you depending on age and condition, in fairness yours looks ok. Need a copper liner, is probably one now that you could reuse, or plumbers merchants if not - don’t try and get away without it, even if last person did!
