Can I just make it clear - I'm not talking about the "official" gas ventilation holes in the floor. My question is about the other holes which are where pipes and wires come through the floor. Is it ok to block these or is the airflow through them taken into account when calculating ventilation requirements?

If those holes you describe are for ventilation why are they so variable
hmy:
IMO there should be a proper grommet / seal to protect the pipe from chaffing.
A purpose built ventilation hole should be deliberately made with a mesh to stop unwanted guests

Our caravan has an air hole directly under the power box which effectively seals it so it is doing no good, and there is one under the alarm siren that didn't have any mesh to stop visitors - it has now! The only place that you need ventilation is where gas can leak to make sure it flows away - Butane and Propane are both heavier than air - or where air is needed for the flame to burn, specifically around the cooker. The water and room heaters are both externally vented and exhausted.

Thanks Dusty - the "proper" holes have grills over them but Bailey only seem to have 1 size of hole saw. A 15mm pipe has a 30 mm hole and so on. These holes have no grill which is why I want to block them up.

Why then has my 'van got a mesh covered ventilation grill in the locker under the front chest? There is no gas appliance or pipe in there.
Gas drop outs are indeed important, but that is not the only reason for ventilation. Don't forget that you and your family need air to breath, and also the gas hob and oven both need air to work.
Its part of the constructions standards that a certain amount of fixed ventilation is provide distributed at low and high level to ensure there is a reasonable amount of air circulation.
