In the process of removing an over-sink light and shaver outlet I

fitted that did not have an integral switch), the light went off so I
was about to get to work but something made me check first.

You mean they had wired the over sink shaving lamp so that it was on the
switched feed to the main room lamp? Might be ok from a lighting point
of view, but you can only shave or charge your toothbrush with the light on!

Long story
short: inside the ceiling switch the red wires were joined and the
blacks went to the switch (one of them had red sleeving on it) resulting
in neutral switching and a permanently live feed to the light! I'm
getting a bit blasé in my old age so this near miss is a good reminder
to check!

Or just turn off the whole circuit...

I've just stripped the paper underneath where the light was and someone
has written "live!" on the wall - presumably, 20 years ago they got the
surprise that I narrowly avoided today.

Well done to the writer of the note, shame the person doing the
wallpaper did not re-instate the warning. Having said that, you would
probably not be able to see it until the lamp was removed anyway!
