TXU's main payment methods and where to find them

TXU Energy offers several ways to pay your bill: online through their website, by phone, by mail, or in person at a payment location. The fastest route is usually the TXU Energy website or mobile app, where you can pay when ready without waiting on hold. You can also set up automatic payments so the bill comes out of your bank account on a date you choose each month.

If you prefer to speak with someone, TXU's customer service line is 1-888-889-8898. They can process a payment over the phone using a debit card, credit card, or bank account. Mail payments should be sent to the address on your bill — TXU will tell you the correct mailing address when you call or check your statement.

Some TXU customers can also pay at Western Union locations or through third-party payment processors, though these routes often charge a fee that TXU does not charge itself. Check your bill or the TXU website to see which options are available in your area.

Key Takeaways

  • Paying online or through the TXU mobile app is free and processes when ready, with no fees added to your bill.
  • You can set up automatic payments from your bank account so you never miss a due date.
  • Phone payments are available by calling 1-888-889-8898, though you will need your account number and a payment method ready.
  • Third-party payment locations like Western Union may charge convenience fees that TXU does not charge for online or phone payments.
  • Mail payments take longer to reach TXU and post to your account, so plan ahead if you choose this route.

Paying online or through the TXU mobile app

The TXU website (txu.com) and the TXU Energy mobile app are the fastest ways to pay. You log in with your account number and password, navigate to the payment section, and enter the amount you want to pay and your payment method. The payment posts to your account within minutes, and you receive a confirmation number when ready.

You do not need to pay the full bill amount — you can pay any amount you choose. This is useful if you want to pay part of the bill now and part later, or if you are behind and want to catch up gradually. The website shows your current balance, due date, and payment history, so you can see exactly where you stand.

If you do not have an online account yet, you can create one on the TXU website using your account number (found on your bill) and your service address. Once you are set up, you can also view your bill online instead of waiting for a paper copy in the mail.

Setting up automatic payments to avoid missed due dates

Automatic payments withdraw money from your bank account on a date you choose each month, usually around the same time your bill is due. You set this up through the TXU website or by calling customer service. You will need your bank account number and routing number, which you can find at the bottom of any check.

Automatic payments are useful if you want to stop thinking about the bill altogether — the payment happens without you having to log in or call each month. You can change the payment amount or pause the automatic payment at any time through your online account or by calling TXU.

If your bill amount changes month to month (which is common with energy bills), you can set the automatic payment to cover a fixed amount each month, or you can choose to pay the full bill amount automatically. TXU will deduct whatever amount you set on the date you choose.

Paying by phone or mail

To pay by phone, call 1-888-889-8898 and have your account number ready. A representative will ask which payment method you want to use — debit card, credit card, or bank account — and will process the payment while you are on the phone. The payment posts within one business day. There is no fee for paying by phone.

If you prefer to mail a check, write your account number on the check and mail it to the address printed on your bill. Do not mail cash. Mail payments take 7 to 10 business days to arrive and post to your account, so send your payment well before the due date if you want to avoid a late fee. Keep a copy of the check or take a photo of it for your records.

Phone and mail payments are useful if you do not have internet access, do not want to create an online account, or prefer not to store payment information online. However, both take longer than online payment, so plan ahead if your due date is coming up soon.

Understanding payment important date and late fees

Your due date appears on your bill and is usually 20 to 25 days after the bill is issued. If you pay after the due date, TXU charges a late fee — the amount varies by location and bill size, but it is typically a percentage of your bill or a flat fee. The late fee is added to your next bill.

If you are paying by mail, send your payment at least one week before the due date to account for mail delivery time. If you are paying online or by phone, you can pay on the due date itself and it will post the same day. If you cannot pay by the due date, call TXU to discuss your options — they may be able to set up a payment plan or connect you with energy information programs.

If your bill goes unpaid for 30 to 45 days (the exact timeline varies by location), TXU may disconnect your service. You can usually restore service by paying the full amount owed plus a reconnection fee. If you are struggling to pay, contact TXU before you fall behind — they have programs for customers facing hardship.

Payment methods that charge extra fees

Some payment locations outside of TXU — such as Western Union, MoneyGram, or certain check-cashing services — will process your TXU payment but charge a convenience fee on top of your bill amount. These fees are set by the third-party company, not by TXU, and range from a few dollars to a percentage of your payment.

Using these services makes sense only if you cannot access the internet, do not have a bank account, or need to pay in cash and cannot do so online or by phone. For most people, paying directly through TXU's website, app, or phone line is cheaper and faster.

Before you use a third-party payment location, ask the representative what fee they charge. Then compare that cost to the cost of setting up a bank account or using a prepaid card to pay through TXU directly, which would have no fee.

What to do if your payment does not post or you need a receipt

If you paid online or by phone and do not see the payment on your account within one business day, log into your TXU account and check the payment history section. Online and phone payments usually post within minutes to a few hours. If more than one business day has passed and the payment still does not show, call customer service at 1-888-889-8898.

For online payments, you receive a confirmation number when ready after you complete the transaction — save this number in case you need to reference the payment later. For phone payments, ask the representative for a confirmation number before you hang up. For mail payments, keep a photo or copy of the check.

If TXU charged your account twice by mistake, or if you paid but were still charged a late fee, call customer service with your confirmation number or check information. They can investigate and reverse the error if one occurred.

Frequently Asked Questions

Can I pay my TXU bill with a credit card?

Yes, you can pay with a credit card online, through the mobile app, or by phone. However, some credit card companies may charge a cash advance fee for utility payments, so check with your card issuer first. Paying with a debit card or bank account directly avoids this potential fee.

What happens if I pay less than the full bill amount?

TXU will accept a partial payment and credit it to your account. The remaining balance carries over to your next bill. However, if the full bill was due and you did not pay it all, you may be charged a late fee on the unpaid portion. Paying something is better than paying nothing, but try to pay the full amount by the due date to avoid late fees.

Can I set up automatic payments if I do not have a bank account?

Automatic payments require a bank account or prepaid card with routing and account numbers. If you do not have a bank account, you can pay online with a debit card, by phone with a debit card, or by mail with a check. Some communities offer low-cost bank accounts specifically for people without traditional banking access.

How do I change or cancel automatic payments?

Log into your TXU online account and go to the automatic payment section, where you can pause, change the amount, or cancel the payment entirely. You can also call customer service at 1-888-889-8898 to make changes. Changes take effect within one to two business days.

What should I do if I cannot pay my bill by the due date?

Call TXU customer service at 1-888-889-8898 as soon as you know you will miss the due date. They can discuss payment plans, connect you with energy information programs in your area, or sometimes extend your due date. Acting before the late fee is charged gives you more options than waiting until after.
