When I bought my house I had it completely rewired by an Electrician, and whilst doing that he re-wired all the lights.
They are wired in standard UK 2-wire format, with T&E from the ceiling rose to the switches, so in the switch I only have live, earth and switched live.
The wires for the one switch in question are chased into a plasterboard wall, and they have plastic capping over them before being plastered in.
My question (and its purely theoretical at this stage), is do you think it'd be possible to manage to poke down from the loft a single core to add neutral at the switch? it's only got to go about 1m straight down the back of the capping.. but is it possible?
I'm thinking an electrician could perhaps use one of these cables..

But what is the chances of being able to manage to shove it down beside an existing cable behind the capping? (I doubt cable rods will fit as they will be wider than this cable i suspect)
I ask as I would like to buy a wifi controlled light switch for this room, and the ones I would like require a neutral connection so they can be powered all the time without needing to leak current to power themselves via a 2-wire live only connection.
I dont want to risk trying to pull up the existing cable to feed up a three core cable.. (im not sure if its clipped behind the capping but i suspect so..), and dont want to re-channel and plaster the wall..
Would it even be allowable to do that as it wont be clipped down the length (but could be at the top and bottom of the capping so about 1M unclipped max in the middle..
Thoughts?
