Which leaves the Holy Grail, discussed on here before - how to
insulate under a suspended timber floor, with no access from
underneath, without removing the floor.

Filling the entire void is not an option, unless you want your joists to rot
away within a few short years.

You can't get access under the floor and you don't want to take the entire
floor up? - then it cannot be insulated, end of story.

You could insulate above the existing floor, with 75mm celotex or similar,
then put a floating floor above that, but then you'd lose about 90mm of room
height (and your internal doors would be 90mm shorter too) plus you'd have
to put new skirtings all the way around
