Renting a Korean apartment's first utility setup: gas, electricity, water, and who to call

Nobody hands you a single "set up utilities" number in Korea. Electricity, gas, and water are three separate accounts, sometimes three separate companies, and your landlord is not going to walk you through it. Here's how to do it on move-in day without losing an afternoon.

The one thing to know before you call anyone: Korean utility accounts follow the meter, not the person. Utility accounts in Korea are tied to the address and meter, not the individual, and if you skip the name change, all rights and responsibilities from the previous user carry over, including unpaid bills. So the first job, before you unpack a single box, is getting your name on all three.

1. Electricity: call KEPCO, ask for English

Electricity nationwide runs through one company, so this is the easy one. Electricity in Korea is supplied by KEPCO (한국전력공사) nationwide. KEPCO's 24-hour electricity consultation and outage number is 123; from a mobile phone, KEPCO instructs callers to use the regional area code plus 123. If your spoken Korean isn't there yet, you don't have to muscle through it: for English support, call +82-2-2105-8504.

Say something like: "Hello, I'm moving into [address] today. I'd like to transfer the electricity account into my name." They'll ask for three things, so have them ready: your name, ARC (Alien Registration Card) number or passport number, and the meter number (계량기번호) found on your physical electricity meter. Before you call, photograph the meter with a timestamp. It settles any dispute about what the last tenant used versus what you did.

2. Gas: the one utility you can't just flip on

City gas is the utility that trips people up, because unlike electricity it's regional, and because the previous tenant's shutoff usually means your boiler, hot water, and stove are genuinely off until someone comes out. When a previous tenant closes their account, the gas supply is cut and a safety inspection is required before it can be restored for a new tenant.

Your gas company depends on your district, not your city. In Seoul alone there are several, and the one serving your building is decided by address:

Call before move-in day, not on it. Say: "I'm moving into [address] on [date]. I need to open a new gas account and schedule a safety check." They'll ask for your name, ARC or resident number, move-in date, address, and contact number. A technician comes to the apartment, checks the line, and turns the gas on, usually within a few days of booking.

3. Water: check the management fee first

Water is the one that sometimes isn't your problem at all. In many apartment buildings and officetels, water is billed through the monthly building management fee (관리비) rather than as a separate individual account. Ask your landlord or the building's management office (관리사무소) this one question on day one: "Is water included in the management fee, or do I need my own account?"

If it isn't bundled, in Seoul you can call Dasan Call Center (120) to be directed to the right waterworks office, and have your address, the customer number on the bill, or the water meter number ready.

What to say, start to finish

1. "Hello, I'm moving into [address] today/on [date]."
2. "I'd like to transfer the account into my name" (electricity, water) or "I'd like to open a new account" (gas).
3. "My ARC number is [number]." (or passport number if your ARC hasn't arrived yet)
4. "The meter number is [number]."

We don't know how long your specific gas company's inspection queue will run that week, it varies by district and by how busy the office is, so book it as early as your lease lets you rather than on the morning you land.
