I just wired a fan controller, the only fitting on the circuit. To the

bit of blue sleeving on it. I connected it to the black supply neutral
wire and didn't put any sleeving on it, because it was already the old
neutral colour. This looks odd - did I do wrong? Is there a rule?

There is no requirement to oversleeve old colours with new colours.

BTW the general guidance is to use the grey as neutral when using the
new colours.

That's interesting, any logic to that? I was reluctant to use black as
switched live, although it wouldn't be unusual with the old colours of
course.
