And cables are made of? They are designed for surface mounting under some conditions. So could well be in sunlight.

All plastics degrade with age. It could be your cable was cooked over the years too.
worse..
" uPVC is known as having strong resistance against chemicals, sunlight, and oxidation from water"
Did they bother with such niceties in the days of VIR?
I'd settle for some black sleeving over the black wire ;-)

I'd run some 20mm plastic conduit. Put an access box near where the cable comes out of the wall and joint on a new length inside the box.
Looks a lot neater than stringing bare T&E along a wall with clips.
I wouldn't. In wet weather water might run down/along the cable into the joint.
Hituf seems to be the one to use.

and the added problem of getting rid of the bloody salesman!
And when I see some of the things people make out of it I almost wish it didn't...
Actually it's curious that plasticised PVC has appropriated the description without qualifier, so we have to use uPVC to describe something closer to the original polymer!
Good question... I have never seen it on VIR, but given the number of times not seeing it on PVC that does not mean the idea had not yet come about...
Well yes that would be nice... Still I have seen rubber insulated (well, at some time in the past) circuits in much worse state than that, where the light switches had to be replaced carefully to avoid contact between the two now uninsulated wires nestling among the rubber crumbs.
solve the PVC / Polystyrene problem) ;-)
I noticed that, and also a local electrical wholesaler doesn't have it anymore. The guys behind the counter didn't know why.
I remembered to take some photos this morning:
Oh, I thought paint was *bad* for cables.
I suppose I ought to be able to find a conduit end fitting that will screw into the base of the light?
I did mean a proper crimped joint like the one on the wiki, not crimped & tied up with elastic bands. ;-)

Surely the correct action to take in that situation would be to pull the fuse and refuse to refit it until a rewire was done?
I'd not be worried about what looks like some mild crazing. Deep cracks, yes.
OK, I'll ignore for a while longer then. I was under the impression that normal PVC-sheathed cable wasn't considered suitable for long-term exposure to direct sunlight, & that paint was bad for the sheathing too. Apparently the wrong impression?
Thanks for the links, but apparently I can ignore this!
conduit with a male adapter will do.
However, 20mm conduit will look much bigger than the wire, and make the whole thing look horrible. Also, you need to consider drainage of condensation inside conduit. I would just paint the wire as I described earlier.
I'd not be two worried about the T&E but be far more so about rain/snow getting blown up inside the fitting and causing it to fail. The cable entry really needs a gland fitting into it.
