The Hellenic Competition Commission (HCC) has put in place the most technologically advanced anonymous information system (whistleblowing), specifically designed for use by Contracting Authorities.

The information available to them because of their role as contract-awarding / tender-launching bodies, allows Contracting Authorities to receive information and complaints regarding the participation of undertakings in these procedures. Contracting Authorities can assist the HCC's work in uncovering cartel practices (bid-rigging) and proceeding with our investigations swiftly and effectively, directly benefiting the Greek economy, consumers and taxpayers, thanks to their help.

Through our dedicated whistleblowing system, Contracting Authorities and other bodies can share valuable information regarding the following practices and / or behaviors, while fully securing their anonymity.

If a Contracting Authority has information about*:

  • Collusive tendering and bid-rigging;
  • Cover bidding;
  • Bid suppression;
  • Bid rotation;
  • Market allocation

For a particular tender or any information that might be helpful to the HCC’s work, send your message through the dedicated Whistleblowing Platform by clicking on the icon below.
