Reporting Your Meter Reading

Your meter has not been read if the word "Estimate" appears to the right of the words "Current Reading" on your Washington Gas bill. Sometimes it is necessary for us to estimate readings, especially in instances in which we cannot gain access to your meter or when the battery in the remote device system, if you have one, needs to be changed.

If we are unable to gain access to your meter, we may leave a postage-paid meter reading card. If you receive one of these cards or you would like to report you meter reading for any reason, you may read your meter, record the reading and report your reading to us by 1) mailing the meter reading card back to us the next day, 2) calling us at (703) 750-1000 or email us with our online form

Reading Your Meter

Mechanical Meters

To read your meter start with the left dial on the row of four, locate the dial hand and record the last number it has passed. Continuing to the right, follow the same procedure for the three remaining dials.

  • If the hand is between two numbers, record the lower number.

  • If one hand is directly over a number, record that number.

For Example …

Mechanical Gas Meter

In this example, the first dial reads 9, the second dial reads 5, the third dial reads 8 and the forth dial reads 7. The complete reading is 9587.

Digital Meters

If you have a digital meter, simply record the numbers that are displayed.

Estimated Readings

Estimated Bills are based on the following:

  • Historical usage;

  • Actual weather; and

  • Length of the billing period.

Estimates are usually very close to actual usage, but actual readings are necessary to keep your bills on track.


Washington Gas strives to bill all customers based on actual meter readings every month, but in some cases an estimate will be used instead of an actual meter reading, in order to limit the possibility of significantly under- or over-billing customers.

Washington Gas reviews accounts with significant usage variance each month, and if the reason for the variation is not apparent, may use an estimate instead. An actual meter reading can be rejected and an estimated meter reading may be used if:

1. The actual meter reading is significantly higher than prior consumption; or

2. The actual meter reading is significantly lower than prior consumption.

Potential Causes of Significant Changes in Consumption:
1. Changes in consumption by the customer

i. A customer may add new gas appliances, such as a pool heater, which would likely increase consumption.
ii. A customer may go on an extended vacation during the winter months which may decrease consumption.

2. Meter issue (Not Typical)

i. The battery on our remote meter reading device may need to be changed.
ii. Different meter read due to a recent meter change.

Estimated Consumption:
When Washington Gas must use an estimate, the estimate is based on your historical consumption and weather factors. For historical usage, we look at usage during the same month the previous year for the location being billed. For weather, we compensate for how cold it was for the month being billed versus normal temperatures.

How to limit the need to estimate readings:
If you are aware of a change in your gas consumption due to new gas appliances such as a pool heater, or other factors please contact Washington Gas at 703-750-1000, so this can be updated in your account information.
