After rent, Greek months move on three lines: power and water, internet and mobile, and how you cross the city or island. None of them is mysterious, but summer heat and ferry tickets surprise people who only priced a spring weekend.
What should you expect for utilities?
Electricity is the volatile piece. Attica and island summers push air-conditioning hours; northern and mountain winters push heating. Older buildings without good insulation amplify both. Common charges (koinohrista) for shared building costs appear beside rent on many Athenian blocks. Water and municipal fees are usually smaller than power but still belong on the lease checklist.
Ask who holds the DEI/PPC or alternative supplier contract before you move in. Name transfers and deposits can delay first bills. Pay from a Greek account once open: Open a bank account.
How do internet and mobile plans fit?
Fiber is common in Athens, Thessaloniki, and Crete city centres through Cosmote, Vodafone, Nova, and local ISPs. Villages and some island interiors remain patchier; speed-test the exact flat. Prepaid SIMs cover arrival weeks; postpaid contracts often want AFM and paperwork depth. Remote workers should budget a backup mobile hotspot for call days.
How do you price transport?
OASA publishes ATH.ENA products for Athens metro, bus, tram, and trolley, including 30-day and longer urban passes at fixed list prices (check the live fare table before you budget). Airport routes use separate products. A personalized card unlocks longer passes. Car ownership adds parking, fuel, and city stress that can erase a cheaper suburb lease: Living in Athens.
Thessaloniki leans on buses and expanding metro coverage; many households still keep a car for Halkidiki weekends. Crete almost assumes a car outside Heraklion or Chania centres, plus ferry or flight hops to the mainland: Living in Crete. City money pages: Athens, Thessaloniki, Crete.

Common misconceptions
A low winter power bill does not predict July in a top-floor Athens flat. Test seasonal peaks.
An OASA pass also does not replace island logistics. Ferries and hire cars are separate budget rows.
Summary
Plan utilities for the hottest or coldest month you will actually live through, not for a mild tourist week.
Use ATH.ENA passes in Attica when metro-adjacent, and treat cars and ferries as explicit island or suburb costs.
