Any ideas what it's purpose is/was, please?

Looks like a stove flue to me.

Does to me as well. Bit odd to be going through the ceiling like
that, single wall flue pipe gets rather hot.

Is it for a stove now removed from the room or the bottom of a pipe
from a rear exit stove into a T in the room above, to facilitate the
remove of soot.
