somewhat difficult, at the moment all we know is different colours at the 3 locations and no obvious signs of L & SL cables yet.Draw yourself a two way diagram for two switches and use the existing wires to achieve it. I.e start from scratch


Another also; someone mentioned the position of the cables for the 2G switch - which I haven't addressed at all, are any of those visible in the ceiling void to get an idea of where they run?Ideally the junction box should be replaced with a maintenance free version such as wago.
I'll take the adulation but I'm really not brilliant, effectively you have done what Eric (i believe it was) suggested back in the first few posts but in a different place.
I suspect splitting them is not going to be simple as I imagine there are going to be other junction boxes.
But let's start with pics of the wiring at the lamps/ceiling roses.
Also is anything visible, such as in the loft? Or any idea where the 2 grey cables go to - the 2 still in use.
