Mystery cable
 

Ive just pulled out a length of dead cable that wasn't connected at
either end.
It was a twin core with red outer sheath containing one red and one
plain green cores. Any suggestions what such cable could have been for?

I had that arrangement you will find the neutral will be a separate single core that connects all the ceiling rosettes. The live cable you describe looped from each light switch with a switched live using the same type of cable went back to the rosette

Core colours don't fit but red sheath suggests possible fire alarm from the past

Definitely lighting cable just pulled loads of it out redoing the lighting circuits in our bungalow.

I've come across that cable wiring up DC lights with one end tied to earth.
Sadly without evidence of a power supply, you may never know!

It's lighting. Seen it loads of times. Very late 60's early 70's
installations used it.

When the red sheathed cable is used often the variation to

is that the neutral carries the earth, and only the switched live (the
red outer sheathed live and earth) provides the earth at the switch, the
permanent lives at the switch usually are just grey sheathed single cores.

It's a rare install but it does exist.
