The idea on the ground floor is to stop draughts coming up through the
boards, but allow a free flow of air under them via the air bricks, so
your carpet should be enough. You don't lose heat downwards,


You ****ing well do.


With a decent carpet/underlay you're going to lose what? 5% of the total
heat loss? In most cases that would be a small saving for a lot of work


make that 85% if the room is wall insulated with DG.
