Fitting a 58W fluorescent to my loft, and cable access is proving a nightmare. I can easily run from an existing rose, but it appears to be a spur itself, not part of the loop. Given that it's my house and I therefore know I won't continue to spur ad infinitum, any issue with taking a spur from that rose to feed the new light? Or am I being daft and this would just be the last looped rose?

Not the end of the world if it's not acceptable, just wanted to check before I started a lot of nugatory effort!

Also, if using blue/brown 3 core to run to a switch, what's the recognised sleeving to indicate a live and switched live? It'll only be a foot or two run along a loft timber, so source will be obvious.

I'd always rather ask and get it right than do half a job :).

On the blue wire which is now used as switch live you use Brown sleeving,in the old days, use to be Red sleeving on a black cable.

Just run a wire from the rose live & neutral & earth to a 4 terminal 5 amp junction box, run switch live & feed to light from the junction box.

That's what I thought, cheers Nightglow. Presume I'm right in thinking that that rose would be the end of a looped in run and therefore I can run an extra light off it no worries? Not really meddled with lights much before, just sockets.
 
Yeah it's likely to be the last light in the circuit. Not a issue coming from that to a single light in the loft. I personally wouldn't bother with a JB. Just take your L,N,E to the switch. Connect live to one side of the switch and connect your switch wire to the other, Connector block the neutral and earth though. Saves the need for a JB and brown sleeving.

I thought about suggesting that way, BUT, as he isn't too sure, I thought it easier for him to use the junction box method.
 
Haha, that's actually the way I was going to do it before I read up on how I *should* continue on from the last looped one.

I like to stick to the regs, even if what I'd be doing is electrically fine :).
