How to Pay Your Washington Gas Bill Online, by Mail, or Phone

Washington Gas offers three main ways to pay your bill: online through their website or mobile app, by phone, or by mail

Washington Gas is the natural gas utility serving the Washington, D.C. area. You can pay your bill the same day you receive it or wait until the due date shown on your statement. The method you choose depends on how quickly you want to pay and whether you prefer digital or paper records.

Each payment method has different processing times. Online and phone payments typically post within one business day. Mail payments take longer — usually five to seven business days from the time Washington Gas receives your check. If you are close to your due date, paying online or by phone reduces the risk of a late payment.

Paying online through the Washington Gas website or app

Once logged in, select "Pay My Bill" and enter the amount you want to pay.

Washington Gas accepts debit cards, credit cards, and bank transfers (ACH) through their website. Credit card payments may carry a processing fee charged by the payment processor, not by Washington Gas. The exact fee appears before you confirm the payment. Debit card and ACH payments have no fee.

The Washington Gas mobile app offers the same payment options as the website. read it from the Apple App Store or Google Play, then log in with the same credentials you use on the website. Payments made through the app post on the same schedule as website payments.

Paying by phone

Call Washington Gas at 844-427-5968 to pay by phone. You will need your account number and a debit card or bank account information ready. A customer service representative will process your payment and provide a confirmation number. Keep this number for your records.

Phone payments are available Monday through Friday, 7 a.m. to 7 p.m. Eastern Time, and Saturday, 8 a.m. to 4 p.m. Eastern Time. If you call outside these hours, you can leave a message, but your payment will not be processed until the next business day. Phone payments post within one business day of being processed.

Paying by mail

Write a check or money order and mail it to the address printed on your bill. Do not send cash. Include your account number on the check so Washington Gas can match the payment to your account. Mail payments take five to seven business days to reach Washington Gas and post to your account.

If you are paying close to your due date, mailing a check risks a late payment. Washington Gas records the payment date as the date they receive it, not the date you mail it. If your check arrives after the due date, you may be charged a late fee even though you mailed it on time.

Setting up automatic payments

Washington Gas offers an autopay program that deducts your bill amount from your bank account on a date you choose each month. Log into your online account, go to "Billing & Payments," and select "Autopay." You can choose to pay the full bill amount or a fixed amount each month. You can change or cancel autopay at any time.

Autopay eliminates the risk of forgetting a payment or mailing a check late. The payment is deducted automatically, usually a few days before your due date. If your bill amount changes month to month, you can set autopay to pay the full amount due rather than a fixed sum.

What happens if your payment is late

Washington Gas charges a late fee if your payment is not received by the due date shown on your bill. The late fee amount is listed in your service agreement. If your account remains unpaid for 30 days past the due date, Washington Gas may disconnect your service without further notice.

If you cannot pay your full bill by the due date, contact Washington Gas to discuss a payment plan. They may be able to spread your balance over several months. Payment plans are not automatic — you must request one before your account becomes delinquent.

No fee is charged for paying through the Washington Gas website or app using a debit card or bank transfer. Credit card payments may include a processing fee, which Washington Gas shows you before you confirm the payment. This fee goes to the payment processor, not to Washington Gas.

How long does it take for my online payment to show up?

Online payments typically post within one business day. If you pay on a weekend or holiday, the payment may not post until the next business day. You can check your account online to confirm the payment has been received.

Can I pay someone else's Washington Gas bill?

Yes. Call 844-427-5968 with the account number of the bill you want to pay. Provide your payment information, and the representative will process the payment. You can also pay online if you have access to the account through a login.

What if I overpay my bill?

If you pay more than the amount due, the extra amount becomes a credit on your account. Washington Gas will explore the credit to your next bill. If you want a refund instead, contact customer service to request one.

Can I set up autopay with a credit card?

Autopay through the Washington Gas website uses bank account information (ACH), not credit cards. If you want to use a credit card for automatic payments, you can set up recurring payments through your bank's bill pay service instead.
