How to Pay Your NW Natural Gas Bill Online and by Mail

NW Natural Gas bill payment options and where to send payments

NW Natural Gas (also called Northwest Natural Gas Company) lets you pay your bill online through their website, by phone, by mail, or in person at payment centers. The fastest route is their online portal at nwnatural.com, where you can pay when ready with a bank account or debit card. If you prefer not to use the internet, you can call their customer service line or mail a check to the address printed on your bill.

The company serves customers in Oregon and Washington. Your bill arrives monthly and shows the due date — typically 20 to 25 days after the bill date. Payments made online or by phone usually post within one business day. Mail payments take longer, so if you are close to the due date, use online or phone payment instead.

Key Takeaways

• You can pay online at nwnatural.com without creating an account, using just your account number and the amount due.
• Phone payments go through their automated system or a representative, and the payment posts the next business day.
• Mail payments should arrive at least five business days before the due date to avoid a late fee.
• NW Natural does not charge a fee for online or phone payments made through their official channels.
• If your bill is past due, the company may suspend service, so contact them when ready if you cannot pay by the due date.

Paying online without logging in

The simplest way to pay is through NW Natural's one-time payment page. Go to nwnatural.com, look for "Pay My Bill" or "Make a Payment," and select the option for a one-time payment. You will need your account number (found on your bill) and the amount you want to pay. You do not need to create a username or password.

The site accepts payments from a checking or savings account (ACH transfer) or a debit card. ACH transfers are free and post within one business day. Debit card payments also post within one business day but may carry a small fee depending on the payment processor — the site will show you the fee before you confirm. If you want to avoid fees entirely, use the ACH option.

Setting up automatic payments or a customer account

If you pay the same amount every month or want to avoid logging in each time, you can set up automatic payments. Create an account at nwnatural.com using your email and account number. Once logged in, go to "Billing" or "Payment Options" and choose "Autopay." You can have the full bill amount withdrawn automatically on a date you choose, usually a few days before the due date.

Automatic payments use ACH transfers and are free. You can change or cancel autopay anytime through your account. If your bill amount varies (because of seasonal heating or cooling use), you can set a fixed amount or let it vary month to month — the system will show you what the next withdrawal will be before it happens.

Paying by phone

Call NW Natural's customer service at 1-800-422-6009 to pay by phone. Their automated system can process payments 24 hours a day, seven days a week. You will need your account number and either a checking account or debit card. The automated system will confirm the amount and posting date before you complete the transaction.

If you prefer to speak with a representative, you can stay on the line after the automated menu, though wait times vary. Representatives are available during business hours (typically 7 a.m. to 7 p.m. Monday through Friday, with limited weekend hours). Phone payments are free and post within one business day.

Paying by mail

Write a check and mail it with your bill stub to the address shown on your bill. The mailing address is usually a lockbox in Portland, Oregon, but always check your specific bill because the address can vary by region. Include your account number on the check so the payment is credited correctly.

Mail payments take five to seven business days to arrive and post. If your due date is fewer than five business days away, do not use mail — use online or phone payment instead to avoid a late fee. Keep a copy of your check or note the check number for your records.

Payment centers and in-person options

NW Natural does not operate its own walk-in payment centers, but you may be able to pay in person at certain third-party locations in your area. These vary by region and are not always available. Contact customer service at 1-800-422-6009 to ask whether in-person payment is an option near you.

Some customers also pay through their bank's bill pay service, which sends a check to NW Natural on your behalf. This is free if your bank offers it, but the payment takes the same five to seven business days as mailing a check yourself.

What happens if you miss the due date

If your payment does not arrive by the due date shown on your bill, NW Natural will charge a late fee. The fee amount varies but is typically a percentage of your bill or a flat amount — check your bill or account for the exact fee. After a payment is significantly overdue (usually 30 to 45 days), the company may disconnect your service.

If you know you cannot pay by the due date, contact NW Natural when ready at 1-800-422-6009. They may be able to work out a payment plan or extension, especially if you have a history of on-time payments. Do not wait until after the due date — calling ahead gives you more options.

Frequently Asked Questions

Is there a fee to pay online or by phone?

No fee for ACH transfers (bank account payments) made through nwnatural.com or by phone. Debit card payments online may have a small fee shown before you confirm. Phone payments are always free.

How long does an online payment take to show up?

Payments made online or by phone post within one business day. If you pay on a Friday evening, it will likely post on Monday. Mail payments take five to seven business days.

Can I pay someone else's NW Natural bill?

Yes, if you have their account number. Use the one-time payment option online or call 1-800-422-6009. You do not need to be the account holder, but you will need the account number and the amount due.

What if I overpay my bill?

The overpayment becomes a credit on your account and will be applied to your next bill. If you want a refund instead, contact customer service and request one — they can mail you a check.

Can I set up autopay and still change the amount each month?

Yes. You can set up autopay to withdraw the full bill amount automatically, and you can log in anytime to see what the next withdrawal will be. You can also pause autopay for a single month if needed.
