Could be double insulated cable inside, if so, do you think there is a requirement for the pipe to be bonded?

Obviously, a plumber as well as a spark

Looks rubbish.

Not a plumber, look at the poor bends in the pipe, if there is one thing a plumber can normally do well, it is bend pipes neatly.

No comment on the earthing, but if I couldn't make a better looking offset in copper tube than that, I wouldn't be putting it on public display.

It would be single isolated inside the switch.
Back box/switch would be classed as an exposed conductive part.

I wouldn't have thought it is a requirement if the cable is double insulated and the run has no sharp edges.

But i was assuming the box was attached to the cpc.
do you think there is a need to bond the pipe, assuming the cable comes into the box double insulated?

Personally i was thinking if the flex was secured inside the back box with a cable clamp then the tube need not be bonded, if it is free to move then i think the tube should be bonded.
but I am open to peoples suggestions.

Very different from a class 1 light fitting.

It looks like there is an insulated and sheathed cable inside the pipe so there would be no need to earth it, it would be no different to a cable tray or basket in that respect.
