Anyway, as it's doing so well it needs repotting. I said "just repot
it in a bigger pot and bung in some more compost" but apparently that's
not official enough for her.

So, any special advice for repotting? It looks like it's just finished
flowering for the time being (several dead flowers, no new buds) so I
thought it would be an ideal time.

This is not the answer you are looking for.

I have a peace lily, in a pot, and it died off, so I assumed it was resting
and put it on top of a cupboard in the bathroom, where it's not really doing
much.

Am I wrong, is this a deceased plant?
