Our Sustainable Procurement Charter sets our ambition to work collaboratively with our supply chain. Our Supplier Code of Conduct outlines our global expectations of suppliers.

Supplier diversity
We are working to maximise service and community impact by diversifying our supply chain to include small and medium-sized enterprises (SMEs) and voluntary, community and social enterprises (VCSEs), noting regional variations in definitions. Region-specific supplier diversity programmes are operated, aligned to local ESG priorities.
Embedding sustainable procurement activity
We've introduced sustainable procurement training for our Procurement teams. This supports existing sourcing and supplier management processes to embed sustainability considerations and required EcoVadis assessments. We continue to partner with EcoVadis to undertake supplier sustainability assessments:
-
735 supplier entities representing 59% of our addressable spend have completed an assessment by 31 December 2025 with an average score of 64 points;
-
363 suppliers completed reassessment in 2025, of which 272 improved on their previous score with an average increase of 4.5 points; and
-
12% of the assessed suppliers have engaged in corrective actions in 2025. Sustainable procurement is embedded in our sourcing and contracting processes, and we have developed tools and training to strengthen accountability and supplier engagement.
In the UK, we are actively mandating our suppliers to undertake EcoVadis sustainability assessments for key supplier renewals. This year, we saw an overall improvement of 5 points in our own EcoVadis assessment score to 65, with a 9-point improvement in the sustainable procurement pillar of the assessment. This is consistent with our bronze medal status.
