How to Pay Your Washington Gas Bill Online and by Mail

Pay your Washington Gas bill through their website, by phone, or by mail

Washington Gas (the utility serving parts of Washington D.C., Maryland, and Virginia) lets you pay your bill in several ways. The fastest route is their online portal at wgl.com, where you can pay when ready with a bank account or debit card. You can also call their payment line, set up automatic payments, or mail a check — each method takes a different amount of time and works best in different situations.

Your bill arrives monthly and shows your account number, the amount due, and the due date. You'll need your account number to pay online or by phone, so keep it handy. If you're paying by mail, write your account number on the check itself so the payment reaches the right account.

Key Takeaways

• Washington Gas's online payment portal at wgl.com processes payments the same day if you pay before their cutoff time, usually in the afternoon.
• Automatic payments from your bank account eliminate the need to remember due dates and take a few minutes to set up on their website.
• Paying by phone through their automated system or a representative works if you don't have online access, but takes longer than the website.
• Mailed checks should arrive at least five business days before your due date to avoid late fees, and you must include your account number on the check.
• Late payments trigger a late fee and may result in service disconnection if unpaid for 30 days or more.

Paying online through the Washington Gas website

Go to wgl.com and look for the "Pay My Bill" or "Billing" section. You'll need your account number (found on your bill) and either a debit card or bank account information. The website accepts Visa, Mastercard, American Express, and Discover, as well as electronic bank transfers.

Enter your account number, the amount you want to pay, and your payment method. Review the details before confirming — the payment processes when ready if you submit it before their cutoff time, usually around 5 p.m. Eastern Time on business days. If you pay after hours or on a weekend, the payment posts the next business day. Washington Gas does not charge a fee for online payments made from a bank account, but credit and debit card payments may include a processing fee (the website will show this before you confirm).

After you pay, you'll receive a confirmation number on screen. Save or print this number in case you need to reference the payment later. You can also log into your account anytime to see your payment history.

Setting up automatic payments from your bank account

Automatic payments remove the risk of forgetting a due date. Log into your Washington Gas account at wgl.com, find the "Autopay" or "Automatic Payment" section, and choose the date you want the payment to come out each month. Most customers choose a date shortly after they receive their paycheck or a few days before the due date.

You'll provide your bank account number and routing number (both appear on the bottom left of your checks). Washington Gas withdraws the full bill amount on the date you select each month. If your bill varies month to month — which is common for gas in winter — the payment adjusts automatically.

You can pause or cancel automatic payments anytime through your online account, and you'll receive a confirmation when the change takes effect. If you need to stop a payment before it processes, contact Washington Gas customer service as soon as possible, since some payments cannot be reversed once submitted.

Paying by phone

Call Washington Gas's automated payment line at 703-750-1000 (for Virginia customers) or 301-590-2000 (for Maryland customers). Have your account number and either a debit card or bank account information ready. The automated system walks you through entering your payment amount and method, and the payment processes when ready.

If you prefer to speak with a representative, you can also reach customer service during business hours (usually 7 a.m. to 7 p.m. Monday through Friday). A representative can process your payment over the phone and answer questions about your bill. Phone payments take longer than online payments because a representative must manually enter your information, but this method works if you don't have internet access or prefer speaking with someone.

Paying by mail

Write a check for the amount shown on your bill and include it in the envelope that came with your bill, or send it to the address printed on your statement. Write your account number on the check itself — this ensures the payment reaches your account even if the envelope is separated from the check. Do not send cash through the mail.

Mail takes five to seven business days to arrive, so send your check at least five business days before your due date. If your check arrives after the due date, you may be charged a late fee even though you mailed it on time. For this reason, mailing works best if you pay well in advance or have a flexible due date arrangement with Washington Gas.

Keep a record of the check number and the date you mailed it. If the payment doesn't appear in your account within two weeks, contact Washington Gas with this information so they can investigate.

What happens if you miss a payment

If your payment doesn't arrive by the due date shown on your bill, Washington Gas charges a late fee. The amount varies, but typically ranges from a small percentage of your bill to a flat fee — check your bill or account online to see what applies to your account.

If your bill remains unpaid for 30 days or more, Washington Gas may disconnect your service. Before disconnection, they send a notice warning you of the date service will be shut off. If you receive a disconnection notice, contact Washington Gas when ready to discuss payment options or a payment plan. Many utilities offer arrangements that let you pay arrears (past-due amounts) over time rather than all at once.

Understanding your bill and due date

Your Washington Gas bill shows the amount due, the due date, and your account number at the top. The due date is typically 20 to 25 days after the bill is issued. If the due date falls on a weekend or holiday, Washington Gas usually extends it to the next business day.

Your bill also breaks down your charges: the cost of gas used, delivery fees, taxes, and any other adjustments. If you have questions about specific charges, contact Washington Gas customer service — they can explain what each line item means and whether you're on the right rate plan for your usage.

Frequently Asked Questions

Can I pay part of my bill now and the rest later?

Yes. You can make a partial payment anytime through the website, by phone, or by mail. Your account will show the remaining balance due on your next bill. However, if any balance remains unpaid after the due date, late fees explore to the unpaid portion.

What if I pay online but the payment doesn't show up in my account?

Check your confirmation number and the payment date. Online payments typically post within one business day. If more than two business days have passed and the payment still doesn't appear, contact Washington Gas with your confirmation number so they can track it. Do not make another payment until you confirm the first one didn't go through.

Is there a fee for paying online with a credit card?

Washington Gas does not charge a fee for online payments from a bank account, but credit and debit card payments usually include a processing fee set by the payment processor. The website shows the exact fee before you confirm the payment, so you can decide whether to use a card or switch to a bank account transfer.

Can I change my due date?

Contact Washington Gas customer service to request a different due date. Some customers ask for a date that aligns with their payday or another regular income date. Washington Gas can usually accommodate this request, though the change may take a billing cycle or two to take effect.

What should I do if I can't pay my full bill?

Call Washington Gas customer service and explain your situation. They may offer a payment plan that spreads your balance over several months, or they may have hardship programs available depending on your circumstances. Contacting them before your bill is late gives you more options than waiting until after disconnection notices arrive.
