I managed to pick up the very heavy duty vinyl that had previously been
stuck down all over. That's left a residue of some fairly thick
adhesive. Do I need to sand that off before applying some self levelling
compound?

I would, otherwise large areas will be unbonded & unsupported. I'm not sure sanding is the way to do it.

That's roughly what I thought. So, does anyone have any idea how to get
the stuff off, please?

SDS drill with a chisel bit (assuming it's a concrete floor) and just tickle the surface of the concrete gently.

Small areas can be done with manual application of an old wood chisel.

I've just done a moderate area here. What was on the concrete seemed to
be a black, presumably painted on waterproof, layer, with, in certain
areas, a glue layer on top.
I haven't replaced the waterproof layer, which didn't seem very
consistent anyway, but just used an old chisel and a paint scraper to
remove most of the glue. Took a few days of intermittent work.

As I'm doing a temporary bodge, I've just laid stick-on tiles on top.
What no one told me and I didn't think about was the temperature. The
tiles say "Do not install below 17 deg C". It was -3 outside when I
installed them in the normally unheated "scullery". The fan heater
didn't seem to make much difference to the concrete floor temp.
