How to Open, Transfer or Close a Residential İZGAZ Natural‑Gas Subscription in İzmir (2026)

If you are moving into a new flat in İzmir in 2026, your heater and hob won’t light until one thing is sorted: your İZGAZ residential subscription. The process is straightforward once you know the order of operations, but first‑time applicants are often tripped up by missing documents, uncertified installers or confusion over the 2026 fee structure. The fastest route is rarely the cheapest, and the cheapest route can stall if you don’t meet İZGAZ’s inspection rules.

This guide sets out a realistic, resident‑focused checklist to open, transfer or close a household natural‑gas account in İzmir. We explain where to start (online or at a customer center), which documents must match your address, what inspections are mandatory, how the 2026 connection and guarantee fees are calculated, and how to avoid common delays—so you can choose the quickest or most economical path with eyes open.

What changed for 2026—and why it matters for your budget

For 2026, EPDK decisions and İZGAZ guidance confirm two distinct payment components at contract signing: a one‑off connection fee (abonelik bedeli) and a device‑based security deposit (güvence bedeli). İZGAZ’s published method uses area‑based inputs for the connection fee—currently the first 200 m² at 8.066 TL + VAT and each additional 100 m² block at 7.016 TL + VAT. The security deposit depends on the gas‑using devices you declare (such as combi boiler, cooker, water heater) under the EPDK framework. Exact totals vary by your apartment’s area and devices, so plan your cash flow but rely on İZGAZ’s official calculation at the time of approval.

If you are providing your own internal installation (piping and appliances) through a contractor, expect an inspection/approval charge by the distribution company before gas can be opened. İZGAZ lists a control fee example for the first 100 meters—around 4,549 TL—plus an additional per‑meter amount beyond that. Meter operations and the gas‑opening visit are charged separately. These items can matter more to your final bill than the headline connection fee if your internal work is extensive.

Decide first: open, transfer, or close?

Choosing the correct path saves days. New build or a flat without an active meter usually means a fresh connection. Taking over a lived‑in apartment with a compliant, existing meter often allows a faster transfer or name change. Moving out requires a formal closure so the next resident does not inherit your deposit or liability.

Scenario	Where to start	Main prerequisites	Key cost drivers
Open a new subscription	İZGAZ online portal or customer center; e‑Devlet can initiate applications for İzmir distribution	ID + title deed/lease + recent utility bill; building completion documents may be required for newer buildings	Connection fee by area, device‑based deposit, installer control/approval, meter and gas‑opening fees
Transfer/takeover	Online contract approval or center visit	Existing compliant meter/installation; matching address documents	Device‑based deposit (if adjusted), meter/gas‑opening as needed; typically lower than a full new connection
Close/move‑out	Online request or center	ID and subscriber details; access for final reading	Final consumption settlement; deposit refund procedures

Required documents and eligibility checks

İZGAZ will not proceed if your identity or address proof is inconsistent. Before you book an appointment or click “approve” online, make sure you have the following aligned to the same address and unit:

• Valid ID (Turkish ID or passport)
• Title deed (tapu) or signed rental contract
• A recent electricity or water bill for the same address
• For buildings completed after 31.12.2021: building permit (Yapı Ruhsatı) or occupancy/usage permit (Yapı Kullanma İzin Belgesi) for new connections
• Certified installer paperwork for internal installation and appliances (for inspection/approval)

If your building’s completion date is close to 31.12.2021, confirm its permit/occupancy status with the municipality before assuming a quick connection. This single check avoids many last‑minute rejections.

Opening a new subscription: the step‑by‑step that works

Start online via İZGAZ’s portal or use a customer center. The online path lets you upload documents and receive contract approvals digitally, which reduces back‑and‑forth. For brand‑new connections, first confirm whether the building already has a compliant internal installation and meter location. If the internal piping and appliances are being installed by you, select a certified internal‑installation firm from the outset. Only certified firms and EPDK‑approved services will be accepted at final inspection.

Once your application is lodged, İZGAZ or the installer submits the internal installation project for review. Where customers have their own installer, expect a distribution‑company control/approval stage and the corresponding control fee. When the project and installation pass checks, İZGAZ calculates your connection fee and device‑based security deposit. You then pay these amounts and any applicable meter or activation fees to secure a “gas‑opening” appointment.

The gas‑opening visit is an on‑site safety inspection and meter activation. If appliances are not present, incorrectly connected, or lack conformity documents on the day, opening will be refused and rescheduled. Keeping your installer available for the appointment prevents costly repeat visits.

Transferring or taking over an existing meter

Where a flat already has a compliant installation and meter, a takeover or name change is typically quicker than a full new connection. Begin with an online application or visit a customer center, ensuring your ID and address documents match the meter point. If the previous subscriber has closed properly, you can proceed with your own contract and the required security deposit based on your declared devices. If the previous subscription is still active, coordinate a closure or formal transfer to avoid service interruption.

İZGAZ may still schedule an on‑site visit to verify safety or reactivate the meter, especially if the supply was sealed. Meter operations and the gas‑opening appointment, if needed, are charged separately. Existing compliant installations can cut days from the process by avoiding fresh project approvals.

Closing your subscription when moving out

Do not hand over keys without closing your account. Submit a closure request online or at a center with your ID and subscriber details. Provide access for a final reading and sealing of the meter. Your final bill settles consumption up to the reading date, and your security deposit refund follows the distributor’s standard procedure. Proper closure protects you from later consumption being billed in your name and ensures the next resident can start without disputes.

What you will likely pay in 2026

Budget for four buckets of charges, understanding that your exact amounts are determined by İZGAZ at approval under EPDK rules:

First, the connection fee (abonelik bedeli) for the dwelling’s area. İZGAZ states that the first 200 m² are charged at 8.066 TL + VAT, with each subsequent 100 m² block at 7.016 TL + VAT. Second, the security deposit (güvence bedeli), calculated per your devices under the 2026 framework. Third, if you provide the internal installation, a distribution‑company control/approval fee applies—İZGAZ’s example lists around 4,549 TL for the first 100 meters plus an additional per‑meter amount thereafter. Fourth, meter operations and gas‑opening have separate published fees.

Be cautious with third‑party “package” offers for internal installations. These are commercial quotes, not regulator‑set amounts. Always ask for certified‑installer documentation that İZGAZ will accept, and compare the distributor’s official fee schedule with any invoice you receive.

Timelines, bottlenecks and how to avoid delays

The sequence rarely changes: online application or center visit; project/installer submission; distributor inspection/approval when required; payment of connection and deposit; scheduling; on‑site meter activation. The total calendar time depends on whether a compliant internal installation and meter already exist. Where they do, a takeover can proceed with minimal technical steps; where they do not, inspections and installer availability become the pacing items.

Three issues commonly cause refusals or repeat visits. The first is uncertified internal work: if your installer is not certified, inspection will fail. The second is document mismatch—names or unit numbers that do not align across ID, deed/lease and utility bill. The third is unclear building status for dwellings completed after 31.12.2021; in such cases you may be asked for the building permit (Yapı Ruhsatı) or occupancy/usage permit (Yapı Kullanma İzin Belgesi) before any new connection proceeds.

If you need the absolute fastest route, prioritise the online portal for initial approvals, book a certified installer early, and keep them present at the gas‑opening appointment. If you prefer the lowest outlay, reuse a compliant existing installation and meter where possible and avoid unnecessary internal alterations that add control‑fee meters to your bill. In all cases, let İZGAZ’s official calculation guide your expectations—do not rely on rounded totals from contractor advertising.
