.... before being able to skim with a self-levelling screed?
This weekend, as part of the kitchen floor improvement project, I dug out
the former hearth bed that was higher than the rest of the (wooden) floor,
and laid an all-in-one concrete mix to bring it to just below the level of
the rest of the floor.
I have some Feb self-levelling stuff that I plan to use to finish the job
so how long to I need to leave the concrete to go off before applying the
top screed?

TIA,

Three weeks to be on the safe side.

A month minimum.

I don't think you need wait at all. Concrete sets, it doesn't dry. Well
it does, but that's just another issue.

You should however leave the SCREED a long time before putting anything
that may be damage by damp, over it.

I agree with NP - you can walk on concrete within 24 hours; walk not
dance, etc. And if you can do that you can lay the screed. The
process of concrete 'drying' is incredibly long - 20 to 30 years by
which time it has actually gone back to being 'stone'.
