Whistleblowing hotline

Here you can report improper, unethical, or unlawful conduct violating our Code of Conduct.

CEZ Group companies, as the largest energy group in Czechia led by its parent company ČEZ, a. s., are aware of their role in society and their responsibility to their customers, business partners, as well as shareholders and employees.

To ensure ethical business standards, the management of the parent company ČEZ, a. s., has adopted systemic measures to reduce the risk of unethical or illegal conduct, which form an integral part of the Compliance Management System of CEZ Group companies. The list of CEZ Group companies is presented here.

The existence of the Whistleblowing Hotline is actively communicated to CEZ Group employees through mandatory training sessions (initial and periodic) and articles on the intranet and in the Company’s magazine Proud.

The Whistleblowing Hotline is designed to ensure the anonymity of the whistleblower and to protect them from sanctions, discrimination, or other retaliation. A whistleblower may be an employee, customer, business partner, or third party/public who makes a report or communicates concerns about suspected misconduct. Whistleblower protection is enshrined in the internal  regulation SKČ_ME_0329 “Procedures for Internal Investigation of Compliance Incidents” and as such is provided to all whistleblowers who make a report through the Whistleblowing Hotline channels.

All reports carried out through the Hotline are objectively and independently investigated by the Audit and Compliance department. Remedial measures are adopted based on the established facts. Dozens of notifications are examined annually in this way.


The Whistleblowing Hotline has been created for

  • CEZ Group employees and statutory governing bodies
  • Business partners of CEZ Group companies,
  • and third parties

that are aware of improper, unethical, or unlawful conduct against CEZ Group’s interests.

The management and operation of the Whistleblowing Hotline is part of CEZ Group's Compliance Management System.

As part of the operation of the Whistleblowing Hotline and the subsequent processing of the notifications received, your personal data (if you provide it) and/or the data of third parties may be processed.

The controller of the processed personal data, within the meaning of the EU General Data Protection Regulation (GDPR), is CEZ Group or a Group company affected by the notified conduct.

Personal data is processed to detect unethical or unlawful acts and ensure an adequate response to such acts. The legal basis for such processing is to protect the legitimate interests of CEZ Group companies (in particular, to defend against financial loss, damage to reputation, or criminal liability) and to protect the life, health, and dignity of those against whom the unethical or unlawful conduct is directed.

The personal data collected is strictly protected by organizational and technical measures. As a rule, access to personal data is limited to designated employees of the Audit and Compliance department of ČEZ, a. s., who are responsible for dealing with unethical or illegal actions. Exceptionally, personal data may be shared with other entities, such as a contracted law firm or state authorities such as the police, prosecutors or courts, upon their legitimate request.

The personal data collected is processed and stored only in Czechia. The retention period for personal data is set proportionately with regard to the nature of the conduct under investigation (e.g., in the case of conduct constituting a criminal offense, the retention period may be set in accordance with the statutory limitation period set for that offense) or concerning ongoing litigation or administrative/court proceedings. After the purpose for which the personal data were processed and stored has passed, they will be deleted, shredded, or anonymized.

Further information regarding the processing of personal data, the rights associated with the processing of personal data, and the possibilities of exercising them, including information about the Data Protection Officer of our Company, can be found here.


This reporting service may only be used to report unethical, unfair or illegal conduct, or situations involving reporting that is not following professional standards or otherwise violates CEZ Group's Code of Conduct.

We would like to ask you not to use the Whistleblowing Hotline to report emergencies (such as fires, work accidents, accidents, etc., for which the integrated emergency services are responsible) or in cases related to business dealings, claims, and customer complaints.

This Whistleblowing Hotline is primarily for users who are unsure whether or how to report unethical behavior.

Please provide as much detailed information as possible regarding the alleged ethical violation in relation to the category you are reporting.

All information provided through the Whistleblowing Hotline is secured against misuse, archived and stored in accordance with the General Data Protection Regulation 2016/679 (hereinafter referred to as GDPR), and other legislation governing the processing and protection of personal data.
