Google isn't clear. What and where are the regs applying to it and
more simply can I put a piece of card in front of the airbrick?

Our gas meter is also in the pantry and there is no airbrick or
ventilation whatsoever. We have recently had the meter changed (routine
scheduled change) and the fitters did not say anything about needing
ventilation.

AFAIK is only gas burning appliances that ate not room sealed need
ventilation to the outside world.

Lots of gas meters are under the stairs with no ventilation. I cannot
say what the current regs are, but it has no more reason to leak than
the rest of the gas pipework (which shouldn't leak at all).

Don't guess if you don't know.
