Modern Slavery Statement

E2S is headquartered in London, UK, with operations in the US and France. E2S has an established Anti-Slavery and Human Trafficking Policy, which sets out a zero-tolerance approach to modern slavery across its operations and supply chains. The policy applies to all persons working for or on behalf of E2S, including employees, directors, officers, agency workers, contractors and suppliers. Key elements of the policy include:
• A commitment to implementing systems and controls to ensure modern slavery is not taking place within its organisation or supply chains;
• A risk-based approach to contracting processes, including the assessment of whether specific anti-slavery prohibitions should be included in third party contracts;
• Requirements for employment and recruitment agencies to confirm their compliance with the policy; and
• Consideration of supplier audits as part of ongoing risk assessment and due diligence.

Since joining Halma, E2S has begun aligning with the Group’s modern slavery control framework as part of a wider integration. As part of their integration ESSL will:
• Enrol senior management and key personnel on Halma’s VinciWorks online modern slavery training;
• Issue and obtain employee sign-off on Halma’s Code of Conduct;
• Complete Halma’s annual internal control certification process;
• Review and align its existing anti-slavery policy with relevant Halma group level policies.
