Open your monthly bill for your utility as soon as you get it.
Write down on a calendar the utility the bill is from, the amount of the bill and the date it's due. You usually have 2 to 3 weeks from the time you receive the bill and the due date.
Write a check for the amount due, or go to a currency exchange or bank and get a bank check or money order for the amount due.
Place the payment and the portion of the utility bill into the envelope they provide with the bill. Put a stamp on it, if required, and mail it. Make sure you mail the payment at least 5 days prior to the due date to give the post office time to deliver it.
Make an electronic payment over the phone or through the Internet. You need a bank account to do this, and some utilities will charge a fee for making the payment this way. If you chose this method, you should make the payment at least a day or two before the due date.
Make your utility payment in person at an authorized agent of that utility. You can call the utility and get a list of authorized payment locations near you. Sometimes they are located in banks, currency exchanges or retails stores. You then can pay by check, money order or cash, and these types of payments can be made on the due date or before.
