It's still perfectly legal for non-electricians to work on house wiring.

black in a house they've moved into.

then what are they doing working on electrics?

If you came across wiring colours you didn't recognise, wouldn't you
ascertain what they referred to before going further?

either that's obvious, or the person concerned should be backing well away from anything as tricky as replacing a plug.

At one time is was quite common to find imported goods with just about any
flex colours you could shake a stick at. So before fitting a mains plug
you'd check which did what. If you valued your health.

Maybe we should litter roads with 'caution: pothole' signs. Taps with 'caution: wet' signs. And microwaves with 'caution, food may be hot' signs. Oh, they do that apparently. Next it'll be 'caution, coffee is hot.'
