Old Electrics (2 wire)

[SwitchTheElectricsOff]

Hi everyone, long time lurker and this is my first post!

I've just moved in to a house built in 1969, and want to replace the current lights with new ones throughout. The wiring is black/red and appears to be a bit thin compared to other old houses I've been in

Should I just wire up the replacement lights, or should I take the wiring back as far as I can, and introduce a new piece to present to the lights?

what I can see at the moment, there are two separate white wires coming down from the ceiling rose with a single wire in each, looking around the house at other cabling, everything else appears to be normal grey cable

You really need to find out if there is a junction box hidden away under the floor of upstairs or in the loft if this is upstairs. Does the other grey cable have an earth core running through between the red/black?

I will look tonight, the cabling goes in the loft, we haven't got boards down so will be easy, if it's boxed I presume I can just rip the cable out and install up-to date cabling

The grey cables I've seen elsewhere around the house do have an earth
