Setting up Greek utilities as a non-resident.
ΔΕΗ, ΕΥΔΑΠ, gas, internet — the practical guide to actually getting your Greek property's utility accounts set up and operational while you live abroad. Documents, processes, payment options, and the bits the websites don't explain.
Most diaspora property owners inherit utility accounts that have been quietly running in a deceased parent's name for years, paid by varying combinations of relatives, accountants, and direct debit set up so long ago nobody remembers. At some point — usually after an inheritance event, a Greek-language bill that nobody understood, or a service interruption — the accounts need to be brought into your name and properly set up. This article walks through how that actually works in 2026.
The five utility categories you'll deal with
For a typical Greek apartment, five utility accounts matter:
- Electricity (ΔΕΗ or alternative providers). ΔΕΗ (Δημόσια Επιχείρηση Ηλεκτρισμού, the Public Power Corporation) was the monopoly provider until deregulation in 2018; now a competitive market with ~15 retail providers (Protergia, Heron, Elpedison, NRG, ZeniΘ, Volton, Watt+Volt, and others). Most diaspora-owned properties still use ΔΕΗ by inertia, but switching is straightforward.
- Water. Regional monopolies: ΕΥΔΑΠ for Athens and Attica, ΕΥΑΘ for Thessaloniki, smaller regional water boards (ΔΕΥΑ-) for other cities and the islands.
- Gas (where applicable). Mains gas is limited in Greece — Athens has it via ΔΕΠΑ/Sympressa, Thessaloniki has it via EDA THESS. Much of Greece runs on LPG bottles or central heating oil instead.
- Internet and telephone. Three main providers: ΟΤΕ/Cosmote (largest, ex-monopoly), Nova, Vodafone Greece. Smaller alternatives exist (Wind became Nova in 2023).
- Building dues (κοινόχρηστα). Not strictly a utility, but typically billed monthly alongside them. Paid to the building manager (διαχειριστής).
What every utility setup requires from a non-resident
Three documents are universal:
- ΑΦΜ (Greek tax identification number). Every utility account needs to be in a ΑΦΜ-holder's name. If you don't have a Greek ΑΦΜ yet, this is the first step — applied for at the local tax office (ΔΟΥ) for your Greek property's area, typically obtained via a Greek lawyer or accountant on your behalf. Cost: free for the ΑΦΜ itself; €50-€200 in coordination fees if done remotely.
- Property ownership proof. Title deed or evidence of inheritance (death certificate plus heir certificate) for the property. Utility providers require this to open an account.
- Greek bank account or representative-held account. For direct debit setup. Greek utilities will accept payment from a third-party account (e.g. your tax representative's client account) but this requires explicit authorisation.
Electricity — ΔΕΗ and the alternatives
Setting up or transferring a ΔΕΗ account
The current account holder's name needs to change to your name. The process:
- Visit a ΔΕΗ branch (in Greece) with your ΑΦΜ, ID, property deed, and the most recent ΔΕΗ bill from the property. Non-residents typically do this through their Greek representative.
- Submit the contract-change application. Greek-language form.
- Pay any outstanding balance on the previous account (this needs verification — often there's accumulated outstanding amount the heirs didn't know about).
- Set up payment method: direct debit from a Greek bank account, IRIS instant payment authorisation, or paper-bill payment via Greek bank.
- The new contract activates within 5-10 business days.
Switching to an alternative provider
Greek electricity market deregulation means most alternative providers can be 10-20% cheaper than ΔΕΗ's standard tariff. Switching is straightforward — most providers handle the ΔΕΗ-side transfer for you. You provide the same documents and authorise the switch. Activation takes 30-45 days because of mandated cooling-off and switching windows.
For absentee owners specifically: ΔΕΗ has clearer non-resident support than most alternatives. The cost saving from switching is often offset by the relationship-management complexity. Many of our members stick with ΔΕΗ for simplicity.
Water — ΕΥΔΑΠ, ΕΥΑΘ, regional providers
Water utility setup is similar to electricity but with regional providers depending on the property's location:
- Athens and Attica: ΕΥΔΑΠ (eydap.gr)
- Thessaloniki: ΕΥΑΘ (eyath.gr)
- Larissa, Patras, Heraklion, Volos, Kalamata, others: ΔΕΥΑ-(city name) — regional municipal water boards
- Some islands: ΔΕΥΑ-(island name) or municipal water authority; smaller islands may have only well water or cistern arrangements
The transfer process matches electricity — provider visit, account change application, outstanding balance settlement, payment method setup. Water is typically billed quarterly. Greek water consumption pricing is among the lowest in the EU; standing charges dominate the bill for an empty property.
Gas (where applicable)
Mains gas is available in:
- Athens and the broader Attica region (ΔΕΠΑ Εμπορίας / Sympressa for retail)
- Thessaloniki and parts of Central Macedonia (EDA THESS)
- Limited rollout in Larissa, Volos, Trikala, Lamia
For properties without mains gas — most of Greece outside the major cities — the alternatives are LPG (propane/butane bottles, delivered by local providers), heating oil (πετρέλαιο θέρμανσης, delivered by tanker), or electric heating only. For diaspora-owned absentee properties, the practical choice usually defaults to electric heating because there's no ongoing customer relationship to manage.
Internet and telephone
Setting up internet at a Greek property requires the property's address to be reachable by the provider's infrastructure (almost always true for urban properties, sometimes a problem for villages and islands). Three main providers:
- OTE / Cosmote (former monopoly, still largest, broadest coverage)
- Nova (merged with Wind in 2023; mid-market)
- Vodafone Greece
For absentee owners, the decision is whether to maintain internet at all. Reasons to keep it active:
- Smart home / camera / alarm system requires it
- Future STR or rental use planned
- Family members or your representative may use it during visits
- Internet-based smart meters (electricity, water) may use it for data transmission
Reasons to disconnect:
- Monthly cost of €25-€45 indefinitely with no usage
- Two-year minimum contract requirements common in Greek market
- Reconnection later is easy (3-7 days typically)
For purely-vacant properties without smart home infrastructure, most of our members disconnect.
The payment problem — and how to solve it
Greek utility providers prefer payment by direct debit from a Greek bank account or by IRIS instant payment from a Greek bank. They will accept:
- SEPA direct debit from EU bank accounts (most providers, but processing is slower)
- Manual payment from any bank via Greek bank account number transfer
- Payment through a Greek tax representative or accountant who holds a client account
- Payment in cash at Greek bank branches or some post offices (impractical for non-residents)
The cleanest setup for diaspora owners is usually: open or maintain a Greek bank account in your name (most major Greek banks accept non-resident applications, though documentation has tightened post-2020), or authorise your Greek accountant or tax representative to operate a client account on your behalf for utility payments.
The change-of-name problem with inherited utilities
The most common practical problem for diaspora heirs: the utilities are still in your deceased parent or grandparent's name. ΔΕΗ, ΕΥΔΑΠ and others continue to bill the deceased's name, sometimes for years, while heirs pay informally. This works until something breaks — a service interruption, a contract dispute, a sale of the property — at which point the misalignment matters.
Resolving it requires:
- Death certificate (sometimes with Apostille if originally issued abroad)
- Heir certificate (κληρονομητήριο) or equivalent confirming you have standing
- Property ownership proof (post-inheritance title deed in your name, or evidence of pending inheritance)
- Settlement of any outstanding balance on the deceased's account
- New account in the heir's ΑΦΜ
Typically takes 4-8 weeks once all documents are assembled. Worth doing — leaving accounts in a deceased name accumulates risk over time.
What we handle for members
Utility setup, account transfer, and ongoing bill management is one of our member admin add-on services. Standard workflow:
- Audit existing utility accounts at the property — what's in whose name, what's the balance history, what's the payment method
- Identify any accounts in deceased-name and prioritise transfer to current heir
- Coordinate with your Greek accountant or tax representative on payment-authorisation setup
- Receive monthly bills on your behalf, scrutinise for unusual charges, pay through authorised account
- Provide quarterly summary so you always know where the money's gone
- Flag any service interruptions, contract renewals, or pricing changes for your attention
See our Bills & Admin service for the full add-on.
This is one of the most common situations we step into. Resolving it cleanly takes a few weeks of coordinated work with your Greek accountant and lawyer. Worth doing now rather than at the point of crisis. Talk to us →
