In the UK, a 'circling approach' is just a 'visual circuit' once tha a/c breaks off from the 'initial' approach, the tracks are determined by the crew.
A 'circling approach with prescribed tracks' (e,g, the NCE 22L/R) will have an approved Thales or Jeppeson plate.
'Swingover' is common, but so is 'Sidestep'. (e.g. NCE 04R to L)
