How do I switch electricity or gas supplier in Greece?

The short answer

Your supply does not stop when you switch: the cables, pipes and meter stay the same. Only the company that sends the bill changes.

📜 The rules in Greece

Switching supplier

Switching supplier is free; your new supplier arranges it. Variable-price contracts may not carry early-exit fees. New since August 2026: after debt flags from three suppliers you cannot switch until debts are paid or settled.
