I take it it’s a problem with loop in at the ceiling rose. 3 plate, or whatever you want to call it.

(Correct me if I’m wrong, or this thread is heading off at a tangent)


It’s easy using loop-in to get things mixed up when the black (now blue) from the switch is live rather than a neutral. It should have been sleeved.

Is this a new fault in existing wiring, or were you working on the circuit and created the fault?

Best advice just now is pictures.
