Liscot, you can't use insulating tape to cover over the wires - to be fair to you, it was a better job than the previous guy did, but still not acceptable. You either need a 3 connector terminal box (so the earth is also secured) which then go inside a chocbox, or you use a 5A junction box. The LN &Ego into the junction box, and then on to the next one, and the lamp holder fly leads come out of the junction box to the bulb, and you use earth sleeve inside the junction box on the bare earth wires.
