A large flowering, late clematis - sorry forget the variety - didn't
get
pruned in the autumn (I forgot). I've just noticed it's now
producing new
shoots all over.

Would it be better to let it get on with it, or prune it now, a bit
late?

Prune.
Cut it back to about 12 to 18 inches.
If it is late flowering it has plenty time to flourish.
And it will look the better for it.
