How to Open Electricity in Istanbul for Foreigners (CK Boğaziçi Step-by-Step)

Electricity registration is one of the most crucial steps for foreigners who plan to start a new life in Turkey. Whether you're moving into a rental apartment or a newly purchased property, having your name on the electricity bill is not just about ensuring comfort , it is also legally significant.

In recent years, especially in metropolitan areas like Istanbul, Ankara, Izmir, and other major cities, immigration offices have started to require an official utility bill as part of the documentation for address registration and residence permit applications. Without a valid utility bill, many foreigners have experienced delays or even rejection in their residence permit process.

In this 2025 guide, I explain everything you need to know about getting an electricity subscription in Turkey from the required documents to payment methods with a focus on Istanbul and CK Boğaziçi Elektrik (for the European side of Istanbul), but the procedures are largely similar across the country.

Required Documents for Electricity Registration

Foreign nationals who wish to register for electricity service in Turkey must submit a complete application file. The required documents serve to verify both the applicant’s identity and their legal right to occupy the property. The list of documents varies slightly depending on whether the applicant is the owner or a tenant.

Documents Required for All Applicants (Owners and Tenants)

1. Photograph of the electricity meter
   A recent photo showing the meter number clearly.
2. Copy of the title deed (Tapu) (if you are the property owner)
   Official document proving ownership of the property OR Notarized rental contract (if you are a tenant). A current lease agreement signed by both parties and notarized.
3. DASK (Compulsory Earthquake Insurance) policy
   Valid and up-to-date policy for the specific property, as required by Turkish law.
4. Copy of passport or residence permit card
   Proof of legal stay in Turkey. If available, a residence permit card with a foreigner identification number (starting with 99) must be provided.
5. Previous electricity bill of the property
   Required for locating the subscriber number and installation number associated with the meter.
6. IBAN (bank account number)
   Necessary for the return of the security deposit when the subscription is canceled.
7. Phone number and email address
   For communication and digital invoice delivery.

Additional Information Required for Tenants

If the applicant is a tenant, the following additional details must also be provided:

• Full name of the property owner
• If the property is owned by a company: company title, tax number, and name of the authorized person

Important Notes:

• All documents must reflect the same and correct address.
• Incomplete or inconsistent applications will be rejected.
• As of 2024, Population Directorates (Nüfus Müdürlükleri) have begun to request an official utility bill under the applicant’s name for address registration. A notarized lease agreement alone is no longer considered sufficient.
• Therefore, completing the electricity subscription process is not only necessary for utility access but also for legal residence registration and residence permit applications.

Where can you register electricity in Turkey?

To initiate electricity service in Turkey, you must contact the authorized electricity distribution company responsible for your region. The process typically involves the following steps:

1. Identify the Electricity Provider for Your Area
   Electricity services in Turkey are regionally assigned. You need to determine which provider serves your specific neighborhood. For example:
   1. CK Boğaziçi Elektrik for the European side of Istanbul
   1. AYEDAŞ for the Anatolian side of Istanbul
   1. Başkent Elektrik for Ankara
   1. Gediz Elektrik for İzmir
2. Visit a Customer Service Office
   After confirming the provider, you must visit one of their official service centers in person (not just a payment kiosk). Some providers also allow online applications, but in most cases, in-person submission is recommended for foreigners.
3. Submit the Required Documents
   If your application file is complete and all necessary documents are submitted, the provider will proceed with opening your electricity account.
4. Security Deposit Payment
   You will be asked to pay a refundable security deposit.
5. Account Activation and Technical Connection
   Once the payment is received, technicians will be dispatched to your property to activate the meter and connect the electricity.
6. Deposit Refund Upon Departure
   When you move out of the property and officially close the electricity account, the security deposit will be refunded to the IBAN number you provided during registration.

If you reside in Istanbul, and specifically on the European side, you can apply online via the official website of CK Boğaziçi Elektrik Dağıtım A.Ş. To begin your application:

1. Go to the official registration portal: https://websube.ckbogazici.com.tr
2. On the homepage, you will see three main options. Click on the "Register" box to create a user account.
3. Fill in your personal details and complete the membership process.
4. Once registration is complete, log in using your Foreign ID Number (YKN / TCN) or Tax Identification Number (VKN) and your chosen password.
5. After logging in, you will be able to view and select the operation you wish to complete (e.g., opening a new subscription). The system will guide you.
6. Once the address verification process is complete, your request will be processed and a technician will be assigned to activate the electricity at your residence.

Frequently Asked Questions

1. Can foreigners open an electricity subscription in Turkey without a residence permit?
Yes. Foreigners can apply for an electricity subscription using their passport. However, if you already have a residence permit with a Foreign ID Number (starting with 99), it is strongly recommended to use it, as some processes (such as address registration) may require it.

2. How long does it take to activate electricity service after application?
In most cases, electricity is activated within 24 to 48 hours after submitting the documents and paying the security deposit. For newly constructed buildings or if technical issues arise, the process may take longer.

3. How much is the security deposit for electricity registration in Istanbul?
As of 2025, CK Boğaziçi Elektrik charges a security deposit based on the connection type and usage category. For a standard residential property, it is usually around 700–1000 TL. This amount is refundable when you close your subscription.

4. Can I apply for electricity registration online as a foreigner?
Yes. CK Boğaziçi Elektrik allows online applications through its portal (https://websube.ckbogazici.com.tr). However, first-time applicants—especially foreigners—are advised to visit a customer service office in person to avoid delays due to missing documents or verification issues.

5. Is a utility bill required for a residence permit application in Turkey?
Yes. Since 2024, Population Directorates require an official utility bill (such as electricity, water, or gas) in the applicant’s name for address registration. A notarized rental contract alone is no longer sufficient for most residence permit processes.
