Gas meters measure the volume of gas, but the energy value of that volume (on which you are billed) is not a constant.

Your usage should be massively down in the last quarter compared to the previous two. Unless of course you run your heating on full blast through summer or run a commercial kitchen? You should be comparing to the same quarter in the previous year - not winter to summer.

OP only had CH installed recently, so the only usage during the winter was for hot water.
