Pay your TXU Energy bill online through their website or mobile app
TXU Energy customers can pay their bill online by logging into their account at txu.com, using the TXU Energy mobile app, or calling their automated payment line. The online method takes about five minutes and lets you see your balance, due date, and payment history all in one place. You can set up a one-time payment or enroll in autopay so the bill comes out automatically each month.
You do not need to be enrolled in autopay to pay online — you can make individual payments whenever you want. If you prefer not to use the website or app, TXU also accepts payments by phone, mail, or in person at authorized payment locations.
Key Takeaways
- Log into your TXU Energy account at txu.com or use the TXU Energy mobile app to pay online with a bank account, debit card, or credit card.
- One-time online payments typically post within one business day, though credit card payments may take slightly longer.
- Autopay enrolls you in automatic monthly payments from your bank account, which usually costs nothing and removes the risk of a late payment.
- If you cannot pay the full amount by your due date, contact TXU before the deadline to discuss payment plans or hardship programs.
- Keep your account number and password secure, and do not share your login details with anyone claiming to represent TXU.
Steps to pay online through the TXU website
Start by going to txu.com and clicking the login button in the top right corner. Enter your username and password — if you do not have an account yet, you will need to create one using your account number, which appears on your bill. Once logged in, look for "Pay My Bill" or a similar button on your dashboard.
Select the amount you want to pay. You can pay the full balance, the minimum amount due, or any amount in between. Choose your payment method: bank account (usually free), debit card (usually free), or credit card (may include a fee). Enter the payment details and confirm. The system will show you a confirmation number — save this or take a screenshot for your records.
Bank account payments typically post within one business day. Debit and credit card payments may take one to three business days. If your due date is within two business days, call TXU at the number on your bill to confirm the payment will arrive on time.
How to use the TXU Energy mobile app
Download the TXU Energy app from the Apple App Store or Google Play Store. Open the app and log in with the same username and password you use on the website. Tap "Pay Bill" or "Make a Payment" — the exact wording depends on your app version.
The app works the same way as the website: choose your payment amount, select your payment method, and confirm. Mobile app payments post on the same timeline as website payments. The app also lets you view your usage, set payment reminders, and report outages.
Setting up autopay to avoid missed payments
Autopay withdraws your bill amount from your bank account on the same date each month, usually around your due date. To enroll, log into txu.com, go to your account settings, and look for "Autopay" or "Automatic Payments." Select your bank account as the payment method and confirm. There is no fee for bank account autopay.
You can change or cancel autopay at any time through your account settings. If you want to pause autopay for one month, you can do that without canceling the whole enrollment. If your bill amount varies month to month, autopay will deduct whatever you owe that month — you do not pay a fixed amount.
If you enroll in autopay and your bank account changes, update your payment method in your TXU account right away. If autopay fails because of an invalid account number or insufficient funds, TXU will send you a notice and you will need to make a manual payment to avoid a late fee.
Payment methods and fees
TXU accepts bank account transfers (free), debit cards (free), and credit cards (fees vary). Some credit card companies charge a convenience fee of 2 to 3 percent when you use them to pay bills. Check with your card issuer before paying with a credit card if you want to avoid surprise fees.
If you pay by mail, send your check or money order to the address on your bill. Mail payments take longer to post — typically five to seven business days — so send them at least a week before your due date. If you pay in person, TXU has authorized payment locations in Texas; call 1-888-892-8123 to find one near you.
What to do if you cannot pay by the due date
If you know you cannot pay the full amount by your due date, contact TXU before the deadline. Call 1-888-892-8123 and ask about a payment plan. TXU may allow you to split your bill into two or more payments over a few weeks, which keeps you from being marked late.
If you are struggling with energy costs, ask TXU about hardship programs or bill assistance. Some programs reduce your bill or help you catch up on arrears. TXU can also connect you with local nonprofits that offer energy assistance. Do not wait until after you miss a payment to call — reaching out early gives you more options.
Keeping your account secure when paying online
Use a strong password for your TXU account — at least 12 characters with a mix of uppercase, lowercase, numbers, and symbols. Do not use the same password you use for other accounts. Change your password every few months, especially if you share a computer with other people.
Never click a link in an email or text message claiming to be from TXU. Scammers send fake payment notices that look real but steal your login details. If you receive a suspicious message, go directly to txu.com by typing the address into your browser instead of clicking a link. Do not give your account number, password, or payment information to anyone who calls you claiming to represent TXU — TXU will never ask for this information over the phone.
Frequently Asked Questions
How long does it take for an online payment to show up on my account?
Bank account payments usually post within one business day. Debit card payments may take one to three business days. Credit card payments can take up to three business days. If you are cutting it close to your due date, pay by bank account or call TXU to confirm your payment will arrive on time.
Can I pay my TXU bill with a credit card online?
Yes, but your credit card company may charge a convenience fee of 2 to 3 percent. Check with your card issuer before paying. If you want to avoid fees, use your bank account or debit card instead.
What happens if my autopay payment fails?
TXU will send you a notice that the payment did not go through. You will need to make a manual payment right away to avoid a late fee. Update your bank account information in your TXU account and try autopay again next month, or switch to a different payment method.
Can I schedule a payment for a future date?
TXU's online payment system does not have a scheduling feature for future dates. You can only make payments that post immediately. If you want automatic payments on a set date each month, enroll in autopay instead.
Is there a phone number to call and pay my bill by phone?
Yes. Call 1-888-892-8123 to reach TXU's automated payment line. You will need your account number and a bank account or debit card. Credit card payments over the phone may have a fee.
