What is the best way to wire ceiling lights?

The ceiling rose junction box with its loop-in wiring is now really showing its age and is no longer a practical (or even safe) installation for most residents who wish to install fancy light fittings. It is still, however, the most common arrangement for new build houses and rewires, probably as the result of the electrician's training and how they consider it to be the norm or they cannot think of (potentially better) alternatives.


So, what is the best way to wire ceiling lights? Should neutral wires be taken to the switches or not?

    But it is spurious, and as far as possible, all joints should be in back boxes of sockets or switches ...




    Appendix 15 seems to have no objection to (BS 60670) junction boxes; and in fact although it may be possible, fig 15B doesn't show branching of 4 mm2 conductors in radial sockets, presumably because BS 1363 socket outlets need only accommodate 8 mm2 of them.
