Energy supplier didnt install gas smart meter

hi all,

my tenant is calling all the service companys to install smart meters which is fine as there paying for it but his energy supplier didnt install the smart gas meter as they said to him the cupboard where they all live in (four for each flat) isnt ventilated as its inside the communal hall

i must admit i have smart meters and live in the same block of flats and my supplier didnt moan they installed both
