Energy Performance Certificate (EPC/PEB)

The energy performance certificate (EPC in Flanders, PEB in Wallonia and Brussels) evaluates a building's energy efficiency on a scale from A++ (very efficient) to G (poor). For co-ownerships, a certificate is required for each lot upon sale or rental. Since 2022-2024, some regions also require a certificate for common parts. The certificate is issued by an accredited certifier and is valid for 10 years.
