Reported risks and mitigations

• Risk: The risk of a breach by overseas suppliers at lower tiers of our supply chain (e.g. within raw materials extraction).
• Area: Within your supply chains
• Tier: Tier 2 suppliers Tier 3 suppliers and below
• Group: Migrants Refugees
• Location: United Kingdom
• Mitigation: To mitigate risks associated with product sourcing we develop targeted policies for high risk areas. For example, in 2025, our Construction division developed a solar panel procurement policy to establish permitted purchase rules and reduce supply chain risk.
• Risk: The risk of the use of low-skilled or migrant labour supplied by subcontractors who are at a higher risk of exploitation.
• Area: Within your own operations
• Mitigation: Our robust due diligence and risk assessment process includes prequalification criteria, contractual obligations and minimum training standards. We also provide modern slavery training to our suppliers through the Supply Chain Sustainability School (SCSS) and collaborate with industry organisations, peers and platforms to inform best practice.
• Risk: The risk of ineffective right to work checks.
• Group: Migrants
• Mitigation: Divisions utilise digital technologies to reduce risk, strengthen compliance and safeguard tenants. For example, digital platforms like Chime are used to track operative skills and qualifications prior to site deployment to ensure that only certified professionals are sent to live jobs.
