Utilities in Korea: Bills, Internet, Garbage & Recycling Guide

Quick Answer

Monthly utility costs for a single person in Korea (2025-2026 figures):

Electricity spikes in summer (air conditioning). Gas spikes in winter (floor heating). Budget 150,000-250,000 KRW/month for all utilities combined. For a broader look at monthly expenses, see our cost of living guide.

How most people pay: Auto-debit (자동이체) from a Korean bank account. You will need a Korean bank account for this. Small discount (~0.5%) on electricity for using auto-debit.

Electricity

Provider

KEPCO (한국전력, Korea Electric Power Corporation) is the sole residential electricity provider. You cannot choose an alternative.

How Billing Works

• Metered and billed monthly
• A yellow paper bill is mailed to your address showing: consumption (kWh), amount due, payment deadline, and a virtual bank account number
• Korea uses a progressive pricing system (누진제): the more you use, the higher the per-unit rate
  • Tier 1 (up to 200 kWh): ~93.3 KRW/kWh
  • Tier 2 (201-400 kWh): ~187.9 KRW/kWh
  • Higher tiers increase sharply
• Average residential rate: approximately 156 KRW/kWh (first half 2025)

Typical Costs (single person, one-room/studio)

• Spring/Fall: 10,000-20,000 KRW
• Summer (A/C): 20,000-50,000 KRW (can jump to 130,000+ KRW with heavy A/C use)
• Winter: 10,000-30,000 KRW (heating is gas, not electric, in most homes)

How to Set Up

1. Call 123 (KEPCO hotline, 24/7) or register online at kepco.co.kr
2. Provide: name, ARC number, address, move-in date
3. No extra documents needed for standard residential (5kW or under)
4. Check for unpaid bills from the previous tenant before transferring the account to your name
5. Tourist/short-term (C) visa holders cannot register independently; ask your landlord

How to Pay

• Auto-debit (자동이체): Set up through your Korean bank account. 0.5% discount offered.
• Bank app: Transfer to the virtual account number on your bill
• Convenience store: Bring the paper bill with barcode to CU, GS25, 7-Eleven, etc.
• KakaoPay/Toss: Scan the QR code or barcode on the paper bill
• KEPCO app: Pay directly through the app

Rate Freeze Note (2025-2026)

KEPCO has frozen household electricity rates through at least Q2 2026, keeping the fuel cost adjustment rate at the maximum of +5 KRW/kWh. Residential rates have been essentially stable since late 2024, even as industrial rates increased. The government has cited household cost-of-living concerns as the reason for maintaining the freeze.

Gas

Provider

City gas (도시가스) is supplied by regional monopoly companies. Major providers:

• Seoul City Gas (서울도시가스): 1522-3884
• Yesco (예스코): 1544-3131
• Samchully (삼천리): Regional areas south of Seoul

What It Covers

• Floor heating (온돌, ondol): The biggest cost driver in winter
• Hot water
• Cooking (minimal impact on the bill)

How Billing Works

• Billed monthly or every 2 months depending on the provider
• Bills arrive 10-14 days after the meter reading
• Massive seasonal variation: winter bills can be 10-15x summer bills

Typical Costs (single person)

• Summer: Under 10,000 KRW/month (cooking and occasional hot water only)
• Winter (Dec-Feb): 70,000-150,000 KRW/month (floor heating)
• Extreme cases: 200,000+ KRW/month reported during cold snaps

How to Set Up

1. Call your regional gas provider’s customer center
2. A technician will schedule a visit to: inspect the lines, check the meter reading, and reopen the gas valve
3. Provide: ARC or resident number. Some providers request a copy of your lease.
4. Transfer the account name to avoid inheriting the previous tenant’s debt

Safety Inspections (가스안전점검)

• The gas supplier conducts mandatory safety inspections approximately every 6 months (twice per year)
• Inspectors check for: gas leaks, facility conditions, and combustor (boiler) installation standards
• Required by Article 19-4 of the City Gas Business Law
• You must allow access. Failure to complete inspections may lead to penalties or service issues.
• If a weekday visit is difficult, you can book weekend inspections via the provider’s app or customer center

Winter Cost Tips

• Set your boiler to moderate (not max) and use “away mode” (외출) when out
• Insulate windows with draft stoppers or bubble wrap
• Use heated blankets/pads to supplement floor heating
• Close doors to unused rooms
• Steady low-temperature settings are often more efficient than cycling between off and high

Water

Provider

Managed by local waterworks offices. In Seoul, it is Arisu (아리수), the Seoul Metropolitan Government’s water service. Seoul’s water rate is approximately 567 KRW per cubic meter for residential use, among the cheapest in the world compared to major cities.

How Billing Works

• Metered every 2 months
• Mild tiered pricing system (no dramatic spikes like electricity)
• Bills include: waterworks fee + sewage fee

Typical Costs

• Single person: 10,000-20,000 KRW per 2-month billing cycle (5,000-10,000 KRW/month equivalent)
• Water is the cheapest utility in Korea

How to Set Up

• Call 120 (Dasan Call Center) in Seoul, or your local district’s waterworks office
• Request a name transfer for your address
• Some offices may request a faxed copy of your lease and ARC
• Most setup is handled over the phone; no technician visit needed

How to Pay

• Same methods as electricity: auto-debit, convenience store, bank app, or KakaoPay/Toss
• Small discount (~200 KRW/payment) for auto-debit
• In apartments, water is often bundled into the maintenance fee (관리비)

Tip

Check for hidden leaks when you move in (running toilets, under-sink drips). A leaky toilet can dramatically inflate your water bill.

Internet & WiFi

Providers

Three major ISPs, all offering fiber-optic connections:

Plans & Pricing: KT Internet Wide (Contract Plans)

All prices in KRW/month, VAT included.

Plans & Pricing: KT Prepaid Internet (No Contract, Foreigner-Friendly)

Prepaid plans are paid upfront for the full term. Installation fee: 36,000 KRW (65,000 KRW with WiFi router). Equipment deposit: 20,000 KRW (refundable).

How to Set Up

1. Choose a provider. KT has the best English support for foreigners (globalshop.kt.com).
2. Check availability at your address (some buildings are wired for specific providers).
3. Documents needed: ARC (or passport), proof of residence (lease contract), Korean phone number
4. Sign up: Online, by phone, or at a provider’s store. KT’s global shop supports English.
5. Installation: A technician visits (usually within 1-3 days), installs the modem/router, and tests the connection.
6. Installation dispatch fee: 29,000-36,000 KRW (one-time).

Contract Terms

• Standard contracts: 1, 2, or 3 years (longer = cheaper monthly rate)
• Early termination incurs penalty fees (you must repay the discount portion)
• Many apartments already have a pre-installed line; ask your landlord before signing up
• Prepaid plans have no early termination penalty but no refund for unused months

Tips for Foreigners

• Bundle deals (internet + mobile + TV) can save 20-30%
• Ask your landlord if internet is included in the rent or maintenance fee
• KT Global Shop (globalshop.kt.com) is the most reliable foreigner-friendly option with English consultation available
• WiFi router is typically included with the plan (GiGA WiFi home ax from KT)
• Data is unlimited, but speeds may throttle if daily usage exceeds 150GB (250GB on 2.5 Gbps plans)

Mobile Phone Bills

Providers

• SK Telecom (SKT): Largest network, best coverage
• KT: Strong coverage, good English support
• LG U+: Competitive pricing, strong 5G
• MVNOs (알뜰폰): Budget carriers using major networks at lower rates (good option for cost-conscious foreigners with ARC)

Plan Types

• Prepaid: No contract, passport only, quick activation. Good for new arrivals. Available at airports and convenience stores.
• Postpaid: Requires ARC + Korean bank account/card. Better value for heavy data users. Typically 1-2 year contracts.
• eSIM: Data-only for short stays. No local number for SMS verification (limits banking/government services).

Typical Monthly Costs

Sample Prepaid Pricing (KT eSIM, 2025)

Counter prices at Incheon Airport are slightly higher.

How to Pay

• Auto-debit (자동이체): Requires a Korean bank account and card. Set up at signup or through the carrier’s app.
• Carrier app: T World (SKT), My KT, U+ app
• Convenience store: Some carriers support this
• Bank app: Transfer to the bill’s virtual account

Auto-Payment Setup

1. Link your Korean bank account or card during plan activation
2. Or set up later via the carrier’s app or by visiting a store
3. Important: Postpaid plans typically require a Korean-issued card. If you only have foreign cards, stick with prepaid.
4. After receiving your ARC + Korean bank card, switch to an MVNO for best long-term value

English Support

• Airport counters (KT, SKT, LG U+) at Incheon Airport have English-speaking staff
• KT’s global customer service is the most foreigner-friendly
• Processing takes 10-20 minutes at airport desks

Trash & Recycling (Important!)

This is the section that catches most foreigners off guard. Korea has one of the world’s strictest waste sorting systems, and violations carry real fines. Most disposal areas have CCTV monitoring. Unpaid fines can cause issues when renewing your visa or leaving the country.

The 종량제 (Volume-Based Waste Fee) System

You must buy official, government-designated trash bags for your specific district. Using the wrong district’s bags or regular plastic bags is illegal. A Gangnam-gu bag cannot be used in Mapo-gu.

Where to Buy Bags

Any convenience store (CU, GS25, 7-Eleven) or supermarket (E-Mart, Homeplus, Lotte Mart). Ask for “종량제 봉투” (jong-nyang-je bong-tu). Specify your district (구) name.

Bag Sizes & Approximate Prices (Seoul, 2026)

General Waste Bags (white/pink/blue, district-specific):

Food Waste Bags (yellow/orange):

Prices vary by district. Sold in packs at convenience stores.

Waste Categories & Sorting Rules

1. General Waste (일반쓰레기) - Use 종량제 Bags

Non-recyclable, non-food waste. Must go in the official bags.

• Tissues, wet wipes, sanitary products
• Broken ceramics, small non-recyclable items
• Dirty plastic wrap, rubber items
• Chicken bones, shellfish shells, eggshells (these are NOT food waste)

2. Food Waste (음식물쓰레기) - Separate Container/Bag

Food waste is processed into animal feed or fertilizer. The “pig rule”: if a pig can eat it, it is food waste.

Goes in food waste:

• Leftover rice, bread, noodles
• Soft vegetable peels, cooked vegetables
• Boneless meat and fish scraps
• Soft fruit (peels and flesh)

Does NOT go in food waste (put in general waste instead):

• All bones (beef, pork, chicken, fish)
• All shells (clam, crab, shrimp, egg)
• Hard seeds and pits (peach, avocado)
• Tea bags, coffee grounds
• Onion skins, garlic skins, fibrous or hard roots
• Herbal medicine residue

Preparation: Drain all moisture before disposing. No non-food items mixed in.

Food waste disposal methods (depends on your building):

• Yellow bags (villas/older neighborhoods): Buy 2-3L yellow bags at convenience stores
• RFID smart bins (modern apartments): Tap your RFID card at the bin, machine weighs contents, charged monthly through maintenance fees

3. Recyclables (재활용) - Free, Use Clear Bags

No special bags to buy. Use transparent/clear plastic bags.

Key rules:

• All recyclables must be clean, dry, and empty. Contaminated recyclables go in general waste.
• Transparent PET bottles have a dedicated separate bin in 2026. Labels must be removed.
• Direct landfilling is banned in the Seoul Metropolitan Area.

4. Large Item Disposal (대형 폐기물)

Furniture, mattresses, large electronics, etc. Leaving large items without registration is illegal dumping.

1. Visit your district office website or app, or use the Bbaegi (빼기) app to photograph the item and register
2. Declare the item and pay the fee (varies by item, typically 3,000-30,000 KRW)
3. Receive a digital disposal number or buy a physical sticker at the community center (주민센터)
4. Attach the sticker to the item and place it in the designated area on the scheduled day
5. Collection usually happens within 1-3 days

Free pickup for large appliances (refrigerators, washing machines, TVs, A/C units): Call Korea Electronics Recycling Cooperative at 1599-0903 or visit www.15990903.or.kr

Disposal Times

• Most districts: Between sunset and midnight (commonly 20:00-00:00 for villas/one-rooms; check your specific district)
• Apartments with dedicated waste rooms often have 24/7 access
• Putting trash out in the morning or daytime is treated as illegal dumping
• No collection on Saturdays in many villa districts
• Check your specific district’s rules (your building management office will have details)

Fines

Fines are enforced. District offices review CCTV footage and can trace violations back to specific households. For foreigners, unpaid fines can cause issues when renewing visas or at immigration.

Apartment vs. Villa/One-Room

Practical Tips

• Keep food waste in your freezer until disposal day to prevent odor and fruit flies
• Download your district’s waste collection schedule
• When in doubt, put it in general waste (safer than contaminating recyclables)
• Your building’s guard (경비원) or management office can show you the waste room and rules on move-in day

Clothing Disposal (헌 옷 처리)

Korea’s waste sorting rules extend to clothing. You cannot throw clothes in general waste bags (except severely damaged or contaminated items). Here are the proper disposal methods.

의류수거함 (Clothing Collection Bins)

Free public clothing collection bins are located throughout residential neighborhoods, usually near apartment complexes, community centers (주민센터), and large supermarkets.

How to find them:

• Look near your apartment’s waste disposal area — most complexes have one
• Ask your building guard (경비원) or management office
• Search “의류수거함” + your district name on Naver Maps
• Your district office (구청) website lists bin locations

What is accepted:

• Wearable clothing in clean, dry condition (shirts, pants, jackets, etc.)
• Shoes (tied together in pairs)
• Bags, belts, hats
• Blankets and bedding in good condition
• Towels

What is NOT accepted:

• Wet, moldy, or severely stained clothing
• Underwear and socks (put these in general waste)
• Torn or damaged items that cannot be reworn
• Non-fabric items

How to use: Place items in a plastic bag and deposit into the bin. Bins are emptied regularly by recycling companies that sort, export, or resell the items.

대형폐기물 Sticker System for Large Items

Large textile items that do not fit in collection bins (mattress covers, large curtains, carpets, heavy coats in bulk) fall under the large item disposal (대형폐기물) system:

1. Register the item through your district office website/app or the Bbaegi (빼기) app
2. Pay the disposal fee (typically 1,000-5,000 KRW for textile items)
3. Attach the sticker and place the item at the designated pickup point
4. Collection within 1-3 days

Donation Options

Donations may be eligible for a tax deduction if you request a donation receipt (기부금 영수증).

Selling: 당근마켓 (Karrot Market)

For clothing still in good, wearable condition, 당근마켓 is Korea’s dominant local secondhand marketplace:

• Download the 당근마켓 app (available in Korean; English-friendly interface in progress)
• List items with photos and price (free listings)
• Meet buyers locally for in-person transactions
• Popular categories: branded items, seasonal outerwear, children’s clothing
• Foreigners can use the app with a Korean phone number

Other selling options: 번개장터 (Bungaejangter, similar to eBay Korea) for higher-value or branded items.

How to Pay Bills

Payment Methods Overview

Setting Up Auto-Debit (Recommended)

1. Open a Korean bank account (requires ARC; mobile ARC accepted at major banks since March 2025)
2. Visit the bank app or branch
3. Register each bill for automatic payment (전기 = electricity, 가스 = gas, 수도 = water)
4. Choose payment date (usually the bill’s due date)
5. Bills are paid automatically each month

For Foreigners Without a Korean Bank Account

• Convenience store payment is your best option: bring the paper bill, pay cash or card
• Samsung Pay works with international Visa/Mastercard (no ARC or local bank needed)
• Ask your landlord or building manager to help with initial setup

Giro (지로)

Giro is the paper bill payment slip system. The yellow or white paper bills you receive are giro slips. You can:

• Take them to any bank and pay at the counter
• Pay at convenience stores (barcode scan)
• Pay via bank ATM
• Scan with KakaoPay or Toss

Apartment Maintenance Fee (관리비)

What Is It?

A monthly fee charged by your apartment or officetel’s management office (관리사무소) covering shared building services. Costs typically increase 3-8% annually, with adjustments usually announced in December for January implementation.

What It Typically Includes

• General building management and administration
• Cleaning of common areas
• Elevator maintenance
• Security/guard services (CCTV, security staff)
• Building disinfection (pest control)
• Repair and maintenance reserves
• Parking lot maintenance
• Shared electricity (hallways, parking areas)
• Sometimes: water, heating, hot water, internet, or basic cable TV

What It Does NOT Include (Paid Separately)

• Electricity (KEPCO bill)
• City gas (if individual metering)
• Internet (if not building-provided)
• Mobile phone

Typical Costs

Average range: 1,000-3,000 KRW per square meter per month.

How to Know What Is Included

• Look for 관리비포함내역 on your lease or building info. This lists what is bundled in.
• Example: If “수도” (water) and “인터넷” (internet) appear next to 관리비포함내역, you do not pay for them separately.
• Always ask your landlord or realtor “관리비에 뭐 포함돼요?” (What is included in the maintenance fee?) and request a recent bill screenshot.

How to Pay

• Usually paid via auto-debit to the management office’s bank account
• Some buildings issue a separate 관리비 giro slip monthly
• Check the 아파트너 (Apartner) app for digital payment and bill tracking

TV License & Streaming

KBS TV License Fee (수신료)

• Current fee: 2,500 KRW/month (30,000 KRW/year)
• Automatically added to your electricity bill (you will see it as a separate line item)
• Applies to any household with a TV
• KBS has proposed raising it to 3,800 KRW/month, but this requires National Assembly approval (not yet passed as of early 2026)

Streaming Services in Korea (2025-2026 pricing)

• TVING and Wavve merged in 2025 (FTC-approved with price freeze through end of 2026)
• Netflix dominates with 14 million monthly active users in Korea
• All services work with international payment methods; no ARC required

Common Questions

Q: My landlord says utilities are included in rent. Should I trust that? A: Get it in writing. Confirm exactly which utilities are included (electricity, gas, water, internet, 관리비). Some landlords include a cap, and you pay the excess.

Q: I just moved in. What do I set up first? A: Priority order: (1) Electricity, call 123. (2) Gas, call regional provider for valve opening + safety check (requires technician visit, so schedule early). (3) Water, call 120. (4) Internet, order online or visit a store.

Q: Can I pay bills without a Korean bank account? A: Yes. Take the paper bills to any convenience store and pay with cash or card. Samsung Pay with international Visa/Mastercard also works. For a long-term stay, opening a Korean bank account and setting up auto-debit is strongly recommended.

Q: What if I get a bill in Korean and cannot read it? A: Call 120 (Dasan Call Center in Seoul) for foreign language assistance. Most bill amounts and account numbers are in Arabic numerals regardless of language. KakaoPay and Toss apps also display bill summaries.

Q: Do I need to pay the KBS TV license fee if I do not own a TV? A: Technically no, but it is bundled into your electricity bill by default. You can request an exemption from KBS if you genuinely have no TV, but the process is cumbersome and rarely done for 2,500 KRW/month.

Q: What is the penalty for wrong trash sorting? A: Fines range from 50,000 to 1,000,000 KRW. CCTV is monitored, and violations are traced. For foreigners, unpaid fines can affect visa renewal. Take sorting seriously.

Q: My gas bill in winter is extremely high. Is this normal? A: Yes. Floor heating is gas-powered. Winter bills of 100,000-200,000 KRW are common for a single person. Use moderate boiler settings, “away mode” when out, and insulate your windows.

Q: Can I use a tourist visa to set up utilities? A: No. Tourist/short-term (C) visa holders cannot register utilities independently. Your landlord would need to keep the account in their name.
