Thanks again for all your replies. In summary then:
- The existing old wiring cannot be 1930's as it looks in pretty good shape ( just no earth )
- Wiring the light in without an earth IS a big no no
- Using an earth from a nearby [new] light circuit is ok, but if I knew what I was doing then I'd be able to rewire the circuit.
- It helps that I'm no where near the bathroom, especially the shower circuit
q1: If i'm just running an earth, what cable would you recommend ? I'm assuming there are different specs of earth wire.
q2: Given that I don't know what CPC stands for, should I go near the wiring at all ?
