The reference voltage for households in Korea is 220V. Sometimes 110V and 220V are available only in some older houses. When using electric products from abroad, you are advised to check the voltage. Korea imposes a cumulative tax that applies gradually higher prices to your electric charges as consumption increases in order to attract energy consumption savings and protect low-income groups. KEPCO (Korean Electric Power Corporation) is the main company of electrical services and takes inquiries related to charges, accidents and membership.

How to Pay Utility Bills:
There are two ways to pay gas, water and electric bills.
Direct Payment System
Go to a bank and pay the bill in person. You can pay cash at a counter or through an ATM (enter the account number written on your utility bill, along with a specified bank) provided you have a bank account. Any post office can also take care of financial tasks related to gas, electric and water bills, so you are able to pay the bills through the post office.
Automatic Withdrawals (Bank Transfers)
You can save time and money in this way by having gas, electric and water bills automatically paid at specific dates. This method prevents you from forgetting to make a payment but obviously you must ensure there is enough money in your account every time. To use an automatic withdrawal, visit a bank, open an account and set up a payment date.
