Installing a ceiling light fitting, Help! Stumped by wires!

I'll have my half sixpence on VIR

That twin looks like pvc, the single is rubber.

I'll give a tenner to Christie Hospital if it isn't.

However the red n black wires appear to be live.

Reconnect the old light to them - see if it lights up

Is there a cpc (bare copper earth wire) within that twin cable?

Without it, you cannot fit a Class I fitting (Class I = requiring an earth connection).

And even if there is I wouldn't advise fitting a Class I light, not without getting the earth continuity checked first - the sort of tw@ who would cut the cpc back is the sort of tw@ who could have done all kinds of other bodges...

The copper wire feels like rubber, but there is no bare copper wire within the twin, there is just the red and black. Here are some more pics of the wires, plus 2 of the old rose and the new fitting.(the 3 wires red,black,copper just went into the old rose)

That is a batten lampholder with a spare terminal to park loop conductors. You have no earth wire.

Do not install that fitting without either rewiring or (at a pinch installing a separate cpc (there are strict rules about this, though).
