Supply Chain and Supplier Due Diligence

The nature of the services S4Capital Monks provides offers limited opportunity for modern slavery and/or human trafficking practices. While this may be the case, S4Capital Monks recognises it remains important to monitor its supply chains to help prevent and identify the risks of modern slavery. 

S4Capital Monks seeks to establish and improve its processes to:

  • include additional enquiries in its procurement processes for goods, services and locations that are assessed as having a high risk of modern slavery or human trafficking, including an evaluation of any internal policies and procedures such suppliers have in place; 
  • better (i) identify, assess and monitor potential higher risk areas in our supply chains; and (ii) mitigate the risk of slavery and human trafficking occurring in its supply chains through enhanced contract term controls (to the extent appropriate and obtainable); and
  • continue building relationships with known suppliers and ensure that expectations of business behaviour are both clear and consistent.


Our commitment to help prevent and identify risks of modern slavery starts with S4Capital Monks' board of directors. The S4Capital Monks Audit and Risk Committee provides oversight on specific issues involving internal and external controls and compliance with legal and regulatory requirements, including compliance with our MSA Statement. 

We monitor the effectiveness of our policies and processes and our relationships with suppliers and we regularly report to the S4Capital Monks' board of directors, including material issues. 


We continue to monitor our performance against the following in order to gauge how effective we are in dealing with modern slavery and human trafficking risks in our business or suppliers: 

  • implementation of our MSA Statement;
  • implementation of our Supplier Code of Conduct, which sets out our zero-tolerance approach to slavery and human trafficking and also helps to communicate a number of important related human rights expectations and is in the process of being rolled out to all of our suppliers;
  • developing a system for supply chain identification, including, where appropriate, adding modern slavery and human trafficking enquiries and controls to our procurement policies (in accordance with our Supplier Code of Conduct); 
  • asking specific questions on modern slavery as part of our procurement processes; 
  • seeking to include protections relating to modern slavery in our terms with third parties for the supply of goods and services; 
  • implementing a reporting process on key performance indicators on an annual basis, including in relation to training and the roll-out of our Supplier Code of Conduct; and 
  • enhancing our compliance program to include regular training on modern slavery, as necessary. 


We will provide regular training as necessary to educate on the importance of implementing and enforcing effective systems to ensure slavery and human trafficking is not taking place in our supply chains. This will form part of a wider programme of compliance training for all relevant members of management and those in our procurement team, which takes place on a regular basis. 


This Modern Slavery Statement 2023 was approved by the Board of Directors of S4Capital plc on 30 April 2024.
