Hi
So i've investigated my lighting upstairs - basically it appears to be a loop at the switch installation - which means bar one ceiling rose the rest all only have one cable which runs to the switch and the other to the bulb holder.
At the switch there are 2 live wires in com and 1 brown wire in 1 way and the blues wires are just terminated - off course there are earths but lets not worry about them
I also know which is my last light switch and also one ceiling rose appears to have the 1st feed from the consumer unit as it has an additional wire and is right above where consumer unit is downstairs so would make sense too
Thats the background - now my question is where should i look to get the power for putting a switch and light in the loft
1) Will be too hard to run cable to switch and back into loft to keep switch loop
2) Can i take it from the ceiling rose which has the additional wire so i just add my neutral, live and earth and sort of create a split of the loop - [See wiring in picture]
3) Can i take the power from the other ceiling rose - i feel if i do this, if the light i take cable from is off the loft light won't work unless i put this light on too
4) do i trace the loop wire from switches somehow - not sure how - and put in a junction box and split
For me it seems like 2 or 4 is best option with 2 being possibly the easiest
Some guidance and help be appreciated - i'm not an electrician but read around and watched some stuff to workout the above
