You can pay FPL bills online, by phone, or through the mail using a credit card, but the method you choose affects whether you'll pay a processing fee.

Florida Power & Light (FPL) accepts Visa, Mastercard, American Express, and Discover for bill payments. The fastest way is through their website at fpl.com or their mobile app — both let you pay immediately without leaving your home. If you prefer to speak with someone, you can call their payment line at 1-800-226-3545. The trade-off is simple: online and app payments are free, but paying by phone costs a fee that FPL sets and updates periodically.

Mailing a check with your credit card information is not an option — FPL does not accept credit card payments by mail for security reasons. If you want to mail a payment, you'll need to send a check or money order instead. For credit card payments specifically, you're limited to online, mobile app, or phone.

Key Takeaways

  • Online and mobile app payments through FPL's website or app are free and process immediately or within one business day.
  • Phone payments are available 24/7 at 1-800-226-3545 but include a processing fee that varies and is disclosed before you complete the payment.
  • You'll need your FPL account number and the credit card you want to use, and the payment posts to your account within one business day.
  • Setting up automatic recurring payments through the website can help you avoid late fees, though you can cancel or change the amount anytime.

Paying online or through the FPL mobile app

The FPL website and mobile app are the fastest and cheapest way to pay with a credit card. Go to fpl.com, log into your account, and select "Pay My Bill." You'll enter your credit card details, confirm the amount, and submit. The payment is immediate, though it may take up to one business day to show on your account. There's no fee for this method.

The FPL mobile app works the same way and is available for iOS and Android devices. Many people find it faster than the website if you're paying on your phone. You can also set up a one-time payment or schedule recurring payments for the same date each month, which removes the risk of forgetting and incurring a late fee.

Paying by phone and what the fee covers

If you call 1-800-226-3545, a representative or automated system will walk you through entering your account number and credit card information. The payment processes immediately, but FPL charges a fee for this service. The exact amount varies — FPL updates it periodically — so the representative will tell you the fee before you confirm the payment. You can hang up without paying if you don't want to accept it.

This fee is separate from any interest or charges your credit card company might apply. It goes to FPL as a processing cost for handling the phone payment. If you're trying to avoid fees, the online or app method is always free and takes about the same amount of time.

Setting up automatic payments to avoid late fees

FPL lets you set up automatic recurring payments through their website so the same amount comes out of your credit card on the same day each month. This is useful if your bill is roughly the same every month and you want to may provide you never miss a due date. You can change or cancel the automatic payment anytime through your account.

Keep in mind that automatic payments use the amount you set, so if your bill changes significantly (which it often does seasonally for heating or cooling), you may overpay or underpay. Check your bill each month and adjust the automatic amount if needed, or switch to manual payments during months when your usage is very different.

What information you'll need to have ready

Before you start a payment, gather your FPL account number (found on your bill) and the credit card you want to use. You'll also need the card's expiration date and the three- or four-digit security code on the back. Have your bill amount in front of you so you know how much to pay.

If you're paying by phone and the system asks for your service address or phone number to verify your account, have those ready too. This verification step protects your account from unauthorized payments.

When payments post and how to confirm they went through

Online and app payments typically post within one business day, though FPL may show them as "pending" for a few hours after you submit. Phone payments also post within one business day. Once the payment posts, it will appear in your account history on the FPL website or app, and your next bill will reflect the credit.

If you don't see the payment in your account within two business days, log back into your FPL account and check the payment history. You can also call FPL customer service at 1-800-226-3545 to confirm the payment was received. Keep your confirmation number (provided at the end of online or phone payments) in case you need to reference it later.

Credit card rewards and whether they apply to FPL payments

Most credit card companies do treat FPL bill payments as regular purchases, so you'll earn rewards points, cash back, or miles just as you would at any other merchant. However, some cards classify utility payments differently or exclude them from certain bonus categories. Check your card's terms or call your card issuer to confirm whether FPL payments earn rewards.

If your card charges a higher interest rate for cash advances or treats utility payments as cash advances, that's rare but worth checking. For most people paying a regular bill, there's no special treatment — it's a standard purchase that earns whatever your card normally offers.
