Viessmann Limited has a zero-tolerance approach to modern slavery and we are committed to acting ethically and with integrity in all our business dealings and relationships and to implementing and enforcing effective systems and controls to ensure modern slavery is not taking place anywhere in our own business or in any of our supply chains."

4. Due diligence and Compliance

Viessmann's Compliance Guideline is its ethical and legal compass, used to ensure the Company upholds its values in every aspect of its work. Section 8 specifically refers to Cooperation with Customers and Suppliers and clarifies that employees, customers and suppliers must respect human rights and comply with laws against child labour. 

To ensure a high level of understanding of the risks of modern slavery and human trafficking in the Company and its supply chains, all managers and employees are required to read, understand and comply with its Tackling Modern Slavery Policy. 

All employees have a responsibility to report any concerns regarding modern slavery, labour exploitation and human trafficking, and management have a responsibility to act upon such concerns in an efficient, timely, effective and fair way. Employees are encouraged to identify and report any potential breaches of the Company's Tackling Modern Slavery Policy and are reminded of the whistleblowing protection offered by the Company. The policy makes it clear that any breaches of the policy will lead to disciplinary action which could lead to dismissal for gross misconduct. This is explained and reiterated both in the Company Handbook and during the induction of all new employees. 

Our whistleblowing policy includes human rights issues such as modern slavery and continues to be publicised as available for our staff, to use if they become concerned. It is mandatory for all Viessmann Limited employees to participate in ongoing Modern Slavery training, to increase awareness and engagement with all our employees and to show the significance of our role in helping to identify, prevent and help eradicate modern slavery, and to show that we are committed to continuously improving our practices. As a responsible business we must source products and services ethically. 

Viessmann Limited ensures that all recruitment and worker placement processes are under the control of the HR Department. Viessmann Limited utilises a Recruitment Principles Compliance Form to ensure no individual or organisation sources and supplies workers without first confirming that workers are not being charged a work finding fee.

Viessmann Limited requires recruitment providers and other organisations in the labour supply chain to adopt policies and procedures consistent with these principles. 

Viessmann continues to use its Ethical Standards for Suppliers self-assessment process, when entering into a new supplier contract or renewing contracts with existing suppliers. The process helps Viessmann to assess the supplier's policies and practices relating to labour rights, the environment and anti-corruption. 

The Viessmann Limited Senior Management team review this Statement annually, or in response to any major business or organisational change, legislative change or any breach or concerns regarding modern slavery, labour exploitation and human trafficking.

Although Viessmann Limited has established strong business partnerships with its primary supplier organisations, it has identified the need to further explore and understand the supply chain of the components part of its business partnerships in more detail, to ensure greater transparency. In 2022 Viessmann Limited will work with its partner organisations to extend the use of its auditing processes.
