Audits, Assessments & Due DiligenceAudits, Assessments & Due Diligence

Every member of our audit team has between 10-25 years of hands-on audit experience.


There’s no substitute for experience and local knowledge. Only a handful of experts in the sustainability industry can claim a rigorous understanding of the voluntary standards and assurance systems – and several of them work here at TDi. 

Our access to a global network of compliance professionals means we can cover all industries at all tiers of the value chain, from mine to retail.

We also train auditors and standards schemes on audits and auditing, so we are ideally placed to understand what is required from the audit process, directly carry out second and third-party audits, and to help build capacity and understanding in your teams.

Our supply chain auditing service enables you to gain complete visibility into your suppliers’ practices worldwide. Our expert teams develop a supplier audit programme to suit your requirements and combine it with our risk data and analysis, so you get a holistic risk-based audit across your most sensitive supply chain operations. 

1. Needs Analysis

We help with audit preparation and prioritisation as well as helping you understand your specific challenges and requirements. 

2. Audit Delivery

We conduct audits and deliver audit reports that capture the information you need to be confident in the performance of your suppliers.

3. Monitoring

We conduct follow up engagements to evaluate supplier progress towards implementing improvement actions identified during audits.

4. Supplier Engagement

We prioritise key suppliers for engagement, training and capacity-building based on risk, dependency and influence.

5. Data

We develop and administer tools to track and manage your audit programme and its performance, including dashboards, aggregated data, and ongoing risk screening.

Local staff

We have a wide network of our auditors based around the globe to ensure that you get the support you need from a skilled team familiar with local context and specifics.
