3) Routing the wiring. He's intending to use 20mm plastic tube
conduit, which for layout reasons has to go up, round, and down to the
sockets/lights/switches. It'd obviously be neater to route all the
cables in one run of conduit - is there some guidance relating to
stuffing conduit with cable?

Yes - there's the fill factor:

Excellent, thanks.


That's purely on space. In essence, if it fits easily, it's OK.


Are you proposing to use singles?


As in a single run of cable? I need to draw it all out, but at the very
least there'll be the 13A socket and the lighting cable running through
the conduit, to keep things neat.

The lighting cable could in theory be quite skinny - 3A, for the 160W load?
