What it is
The tariff policy of DEYA Dion-Olympos for the 2025-2029 regulatory period (board decision 80/2026, approved by the Municipal Committee) includes a special tariff for large families and people with a disability above 80%: 50% off the first 100 m³ per four months.
- Large families with 4 or more children: the discount applies until the children come of age (18, or 25 if they study or do military service); when the first child of a 4-child family comes of age, the family moves to the normal tariff. Total household income must not exceed €40,000 a year for 4 children, plus €5,000 for each further child.
- People with a disability above 80%, with a valid KEPA certificate.
The discount covers the main home only, not a holiday home, plot or business premises. The documents are updated every year.
