2 plate lighting question

Former Community Member
Former Community Member
Hi all,


New to the forum so please be kind! I'm starting a rewire of my home and have decided for a multitude of reasons to go with wiring the lighting using the 2 plate method(smart light switches and the like mostly requiring neutral). I was intending and can't see any negatives to doing it slightly differently in that I wasn't going to take the feed for following on differently switched lights from the switch, instead I plan to supply one junction box from the consumer unit and then spur off for each room's lighting (may install a second jb depending on how congested the first is looking). 


In doing this I would avoid there ever being a need for more than 3 cables in a single light switch, i.e. worst case scenario i'd have permanent supply (from jb), switched supply to light fitting and lastly in some cases a 3C & CPC for 2 Way switching. Plus in my mind make future installs easier, i.e. any additional feed coming from one central point.


Can anyone think of any good reason not to do the above? Can't see anything in the regs to suggest this would be a problem? 


Cheers all!

    Of course it does not need to be accessible from above, I have in tricky cases in the past used a plasterboard mounting box in the ceiling with a blanking plate to act as an accessible junction box from below, both the socket sized ones and the round conduit box sized ones where the lids are flatter. It does not look quite as odd as an orphaned ceiling rose, which is another approach. (I have also seen an installation where they clearly had been sent a job lot of ceiling roses and no junction boxes, as they were used for every junction, some hidden in voids some visible...)

    All these approaches work, but they do need to be maintainable, and while in a perfect world you'd find drawings and photos in an envelope by the consumer unit to aid that, if that is not the case, at least give the next man in a good chance, and make it fairly obvious how it has been done.

    Mind you if you ant a smile, take a look at the pictures in the first post of this thread to see that 'access with tools' can mean rather different things to different installers.

    Mike.
