Thanks @Nef @hvsds and @M4xime
"perhaps just a rub down with sandpaper and couple of coats of satinwood might do the trick?" this appeals the most so far.
It's a small spare room I'm turning into an office but I've actually, for once, made an effort with prepping and painting the walls so it seems a shame to have crap skirting beneath them.
I'm also tempted with a new floor of some description - prob just some kind of LVT. Something that can take my weight on as swivel chair 22 hours a day (I'd put a rug/runner down, I'm not a complete monster). If so, shouldn't that go underneath the skirting? Which brings me back to ripping it off and putting on new?
