Default Back boxes for plasterboard walls

Am I correct in saying that a dry lining back box does not need to be
screwed to a stud or noggin? Screwing only applies if fitting a steel
box in this location.


I think most electricians prefer the metal box on a noggin especially if on first fix they have access to the stud work only using dry lining boxes when an additional socket is mounted in an existing wall. The main reason I am told is that the front lip of the dry line box is often visible especially when using some of the decorative outlets.

I have seen an example of an electrician fixing a metal box to an existing studded wall by glueing a suitable spacer piece to the other PB back then screwing the box to the spacer.
