I've absolutely no idea of the plant's name. It stands 14cm high,
has
pink flowers, is bushy, with thick squidgy leaves that are oval with
very
pronounced scallops around the edge - and it couldn't be more
healthy.

A few weeks ago I stuck one leaf taken from this 6-month old
houseplant
into some new indoor soil in a vain hope that a new one would grow.
There's
good news and bad because the leaf developed a huge root system
beneath the
soil but all you can see above the soil is the original leaf and
nothing else.
Am I being impatient and in another few weeks a lovely new stem
will shoot
up?

Probably.
Let's play the guessing game: I opt for Kalanchoe

I agree with Franz's answer.
Your cutting will probably only start to show real new growth next
spring when the weather warms up, succulents usually go rather dormant
during the winter.
