OK - all I can see in the photo is a switched live, a neutral, and something ending in a choc-block.
If the latter is the live loop then what's the point of it being there if there's no neutral loop?
If the permanent live to the switch is also in it (i.e. if there are two conductors) then why is it poking out of the ceiling? It doesn't need to be.
Or are there 3 conductors in it, if the loop carries on? But again why have it poking out of the ceiling?
I'm just trying to work out what's going on, as what I can see makes insufficient sense.
Sorry BAS but makes perfect sense to me. If its the last light on the loop then you'll have LNE in and a switchline T&E. N in goes straight to the fitting, L in goes to the choc block and connected to one leg of the switch cable. L from the switch goes straight to the fitting and all earths joined together which do indeed look like they may be stuffed up into the ceiling. If its the last light on the circuit then there wont be a neutral loop, as for why the choc block is poking out of the ceiling then thats down to whoever changed.wired the fitting originally, i never stuff the loop in the ceiling unless im stuck for space in the fitting, i guess its just personal preference.
Hope thats cleared it up for ya
