2 plate lighting question

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!

  • I don't see any regs problem with what you suggest at all.


    If you are going for a central joint box approach, it is more conventional to take everything back there - switch cables and light cables - often with cables with an extra core or two to each position - which then gives you a lot more freedom to adjust layouts at a later date or even make temporary changes (e.g. arrange for a room being redecorated to have its lights switched from another room). Think big adaptable box with loads of wago terminals rather than a traditional round JB with 4 or 6 fixed terminals.


    Central JB approaches also give you some additional flexibility - e.g. the way rooms are divided between circuits - e.g. I have 4 circuits over 4 floors but intermingled so where two rooms meet the rooms are on different circuits (e.g. landing on one circuit, bedrooms off that landing on another) - that way if one circuit fails you should still have some light in every room,
