Reported risks and mitigations

• Risk: PPE manufacturing for factory and migrant workers in high-risk regions, including Xinjiang, Malaysia and Taiwan, where forced labour concerns and limited audit access reduce supply chain visibility.
• Area: Within your supply chains
• Tier: Tier 1 suppliers
• Group: Women Migrants
• Location: China
• Mitigation: We manage modern slavery risk in PPE, workwear and branded uniform supply chains through two framework agreements. Monthly supplier reviews include a risk matrix, checks that key suppliers maintain ethical and anti-slavery statements, and assessment of any risks affecting workers involved in manufacturing and distribution. Identified risks are categorised, investigated and managed through agreed mitigation and monitoring actions across relevant supply chain locations.
• Risk: Waste management and recycling operations across UK sites rely on complex supply chains. Temporary, agency and lower-skilled workers are at higher risk due to multiple service providers.
• Group: Migrants Refugees
• Location: United Kingdom
• Mitigation: All our tenders for waste management requirements (inclusive of hazardous waste, chemical cleans, grits, screenings and general waste collections) have been tendered over the last 12 months. Within each tender, questions on modern slavery are included building on lessons learned from previous tenders and updated to adhere to the latest policy and market risks.
• Risk: Field operatives and contractor crews deliver network maintenance, repairs and capital works across the UU region. Risks arise from subcontractors, off-framework spend and limited oversight.
• Group: Women Migrants Refugees Children
• Location: China United Kingdom India
• Mitigation: We have strengthened oversight of our chemical supply chain through enhanced due diligence, including supplier site visits to assess working conditions and employment practices. We continue to work with industry partners through established water sector forums to address modern slavery risks collectively, share intelligence, and identify opportunities for a coordinated approach to improving supply chain transparency and worker protections.
