It can also create a more appealing appearance by revealing old details that have been obscured by climate impact over the years. In short, we can help our customers to reduce costs, make an effort for the environment and also often contribute to a more attractive urban landscape – an ideal combination!

Our whistleblowing service
Our whistleblowing service exists to capture early warning signals and thereby reduce risks. It is an important tool for promoting high ethical standards and maintaining a high level of trust in us as a company.
The whistleblowing service can be used to alert incidents, events or misconduct that may affect employees, our organization, society or the environment.
Employees and others are encouraged to report suspected cases of misconduct or unethical behavior within Corteco. The report may include information about crimes, irregularities, and violations - or other acts contrary to EU or national laws, in a work-related context.
You do not need to have any evidence to support your suspicions, but all reports must be made in good faith.
Corteco's whistleblowing function allows for completely anonymous reporting of any problems or potential non-compliance via an external party. It is important to include information on where the incident in question occurred and who it affects.
How it works
- Submitted data will be handled, investigated and followed up properly and discreetly with the possibility of anonymity and confidentiality throughout the process.
- If you report via our online tool, you can follow your case via the portal.
- Sharing your personal data is voluntary but remember that this makes you non-anonymous.
- Any kind of retaliation against a whistleblower is a violation of the Corteco Code of Conduct and will not be tolerated.
