Hi, We are a share house of four without airconditioning/heating nor a TV. We only use gas for cooking and hot water, but are all conscious of what we're doing. Between our most recent actual meter reads, our average daily use was 309MJ per day. For comparison, this time last year we were only using 35.52MJ daily. How do we know that there is not a gas leak? May I request AGL to review the bill and share the corrected bill. Thanks,
