🩺 I depend on medical equipment or I am vulnerable: is there extra protection in Greece?

The short answer

People who rely on electrically powered medical equipment, older people and people on a low income often get extra protection. You usually have to register or tell your supplier and grid operator.

📜 The rules in Greece

Vulnerable and medical customers

HEDNO keeps the Vulnerable Customers Registry. Social tariff (ΚΟΤ) users are included automatically. Households with a member on life-support equipment at home, or where all adults are 70 or over, apply via IDIKA within income limits. You must reapply every year.

  • The yearly renewal is due within one month after the income tax return deadline. Changes to your details can be submitted at any time. (deddie.gr)
  • Registered vulnerable customers also get stricter conditions before a supplier may terminate their contract. (deddie.gr)
  • On the social tariff (ΚΟΤ), households with a member on life support keep the discount up to their quarterly consumption limit even when they use more than that limit, unlike other households. (raaey.gr)
