EPC Definition 2026: A-to-G Labels and Price Impact

EPC: quick definition

The EPC (Energy Performance Certificate), called PEB in French-speaking Belgium, is an official indicator of the energy performance of a dwelling. It measures theoretical energy consumption per square metre per year, expressed in kWh/m².year.

The 7 EPC labels from A to G

• A (≤ 45 kWh/m².year)
• B (45 to 95)
• C (95 to 150)
• D (150 to 210)
• E (210 to 295)
• F (295 to 400)
• G (> 400)

Impact on property value

A 2-label gap (e.g. A vs C) can mean a 15 to 25% price difference.
