No airbrick for the first floor

pieroabcd

Hi,
I've noticed that while I have airbricks at the ground and second floor to aereate the subfloor I don't have it at the first floor.
I imagine that the airbrick was present and later covered by the kitchen extension installed 10 years ago by the previous owners.
I'm wondering if this lack poses a risk for the subfloor. I have some decent space around the heating pipes that provides some airflow (at the touch it feels like there's some cold air movement) and I can also remove one lightbulb from the downlights below, but is it enough to provide enough areation?

Last summer I opened a large part of the subfloor boards and I noticed that they were quite dry, not even remotely damp.

Thanks

Air bricks are only required at the ground floor, to ventilate the void from ground moisture. The upper floors don't need them.

Only old houses with fires would have air bricks into the room.
