Greek Utility Emergency Numbers: The Complete Contact Guide for 2026
All emergency and fault-reporting contact numbers for Greek power, water, gas, and internet utilities — organised by region, available 24/7 status, and what to have ready when you call.
When a utility fails — especially power — you typically have only minutes before your phone and devices start losing charge. Having emergency contact numbers written down somewhere accessible (not just saved in your phone) is one of the most practical preparations any Greek household can make.
This guide compiles all essential Greek utility emergency contact numbers, organised by utility type, with notes on availability, what to have ready, and what to say when you call.
Power: DEDDIE / HEDNO
DEDDIE is responsible for the distribution network serving almost all of Greece. When your power goes out, DEDDIE is the first call.
Main fault reporting line: 11500 - Free call from any phone (landline or mobile) - Available 24 hours a day, 7 days a week, 365 days a year - Covers all of Greece except some island communities with autonomous generation where local offices handle faults
Alternative number: 2111900500 - Available when 11500 is congested during major events - May not be free depending on your calling plan
DEDDIE website: deddie.gr - Online fault reporting available (slower than calling during active outages) - Scheduled outage lookup: deddie.gr → Scheduled Outages
What to have ready when you call DEDDIE: - Your address (including municipality and prefecture) - Your electricity meter number (αριθμός παροχής — found on your electricity bill) - Your electricity supplier account number - The approximate time the outage started - Whether your neighbours are also affected (helps DEDDIE assess fault scope)
Ask DEDDIE for: - A fault report reference number (αριθμός βλάβης) - An estimated restoration time - Whether the outage is scheduled or unscheduled (this affects your compensation rights)
Write down the reference number immediately. You will need it if you later file a compensation claim.
Water: EYDAP, EYATH, and Local DEYAs
EYDAP (Athens and Attica): - Fault reporting: 1022 - Alternative: 210-2144444 - Available 24/7 - eydap.gr
EYATH (Thessaloniki): - Fault reporting: 2310-966600 - eyath.gr
Local DEYAs (all other areas): There is no single national number for DEYA utilities — each municipality has its own organisation. To find your DEYA's fault reporting number: - Search "[your municipality name] ΔΕΥΑ" on the web - Contact your municipal offices during business hours - Ask a local pharmacy or church notice board for the posted number
Keep your local DEYA's fault number written down — finding it online during an emergency (with failing connectivity) is harder than it sounds.
What to have ready when you call your water utility: - Your address - Your water meter number (found on your water bill) - The approximate time the disruption started - Whether the problem is complete cutoff or low pressure
Gas: DESFA, EPA Attikis, and Local Suppliers
Natural gas service in Greece involves two layers:
DESFA (transmission pipeline network): National gas transmission, not contacted directly by residential customers for faults.
EPA Attikis (Athens distribution): The gas distribution network in Attica. - Fault and emergency line: 10551 - Available 24/7
For other areas: Contact your local gas distribution company. Many areas outside Athens do not have natural gas distribution.
Important: For any situation involving a gas smell or suspected leak, call 10551 (or 112 for national emergency services) immediately. A gas leak is a life-safety emergency — do not delay to look up numbers or consult guides.
Internet: ISP Fault Lines
Cosmote: 13888 Vodafone: 13830 Nova: 13831 DIGI: 1350
ISP fault lines are generally available extended hours (often 08:00–22:00) but not always 24/7 — check your specific contract for support hours.
Most ISPs also have mobile apps that include fault reporting and service status pages. During major network events, app access may be faster than phone lines (which become congested during widespread outages).
National Emergency Services
112: European emergency number — police, fire, ambulance (all Greece) 100: Greek police (Ελληνική Αστυνομία) 199: Fire service (Πυροσβεστική) 166: Medical emergency / EKAB (ambulance) 108: Coastguard (Λιμενικό) 10300: Civil protection general information line
Keep It Written Down
The most important advice in this guide is the simplest: write these numbers down on paper and put them somewhere accessible in your home. A power outage may leave you without a working screen. A storm may disrupt mobile data. A simple piece of paper taped to the inside of a kitchen cupboard, with DEDDIE at 11500 at the top in large type, costs nothing and may save you significant frustration during your next outage.
Outage.gr is also always available through mobile data (even when your home Wi-Fi is down), and the My Area section shows nearby outages and scheduled maintenance in real time.
