Mandatory EU-standardized scale takes effect

The Energy Performance Certificate (EPC) is a fundamental document for homeowners. Whenever a property is sold, rented, or leased, the EPC must be presented to provide prospective buyers or tenants with a clear view of the building’s energy performance.

There are two types of certificates: the simple consumption certificate, which reflects the property’s actual energy use over the past 18 months, and the more informative demand certificate, which considers the building’s structural and technical characteristics and is therefore independent of individual user behavior.

Energy efficiency is rated on a color-coded scale from A to H, with A indicating the most efficient and H the least efficient properties. These classifications are governed by the Building Energy Act (GEG), specifically Sections 80 to 86.

Improved comparability with the new scale

2026 introduces important changes to the Energy Performance Certificate (EPC) that every homeowner—whether of a house, apartment, or villa—should know. The previously adopted EU Energy Performance of Buildings Directive (EPBD) must be implemented into national law by the end of May 2026. As part of this process, EPCs will be standardized across Europe, with the new rating scale running from A to G.

Important: Existing certificates using the old scale will no longer be valid. When selling or renting your property, you will need a current certificate reflecting the updated A-to-G scale.
