Gas meter size?

[charliechaplinspants]

Yes 35mm for 2 combis, your also forgetting the cookers and fires that have been mentioned. Discharge rate for 35mm pipe is 32m/h over a 3 meter section so depending on the size of the building and distance from meter to appliances 35mm minimum and am not talking about the service pipe.

This is all very subjective, a site survey is needed

OP was asking if meter was big enough, not pipe sizes to boiler. Clue is in Topic heading.Think Fitz1 and Bengasman have covered options.
