No bueno! First things first, check your meter and see if the number is higher or lower than the bill; occasionally it will be an estimate in which case you should be able to provide your own actual reading to your provider, or it will right itself by the next bill.
Next, if the read is accurate, check for leaks. Generally you will need a plumber to check for you, but better to be safe. (Edit: adding, if there is a leak you will most likely still be liable for the bill).
Otherwise, it may just be the gas price increases have come into effect, and you're seeing that on your bill now.
Reading is accurate. Haven't checked for leaks, but my graphs don't suddenly spike and are comparable to last year. I think shit's just expensive....boo
😱 😨 that's rude. That's very rude. Times like this I'm grateful that my place has zero gas heating. But even the freaking daily supply charge alone for a gas stovetop is $1/day.
