The twin red being connected to L1 and L2 of a 2 way switch suggests these are the strappers.

if all cables go to a joint box, then yes there will be a cpc at each point, but if the twin red without cpc goes directly to another switch, then onto the light…
But then the light may have a black and cpc, which may be continued down to the other switch……


I’ve confused myself now.

Yes this is probably how it was wired, using a black and CPC at the light points. Very common method in some parts of the country.

Hi Everyone, thanks to everyone who's replied, this is the switch in question, I believe it does go to a jointing box in the loft. So am I correct in saying that earth sleeved wire just goes into the earth terminal that's on the new face plate and the red wires are like for like swaps.?

yes. earthing the metal faceplate is mandatory, and as the lugs are plastic, i would add a fly lead to the back box, or leave existing where it is and fly lead to faceplate.
