Sometimes extreme weather conditions, emergencies or other conditions beyond our control disrupt meter-reading schedules. If access to your meter is a problem, we will contact you to make other arrangements to get your meter reading.

When we cannot obtain a meter reading to calculate your bill, we estimate your usage based on current use by similar customers. Any variation between your actual use and the estimate is accounted for the next time your meter is read.

If your usage has been estimated, an "E" appears next to the meter read number on your bill, and the word "estimated" is printed at the top of the bill.

Gas usage in this example is A - B = C, or 8 CCF.
