Responsible Sourcing

Responsible Sourcing Auditors

All Good Delivery refiners and new applicants must engage an independent third-party auditor from our Approved Auditors List to conduct annual Responsible Sourcing audits.

We manage our Approved Auditors List to ensure auditors meet the stringent standards we expect.

Auditors are required to demonstrate fulfilment of the requirements detailed in LBMA’s Responsible Sourcing: Third Party Audit Guidance. Auditors must carry out third-party audits based on the ISAE 3000 Standard. To become accredited, auditors must submit an application form providing details of their relevant experience, skills and quality control and governance processes. To receive an application form, please contact

We engage with auditors through training sessions and webinars, but most importantly through robust quality control. Ongoing review and enforcement of Approved Auditor requirements are important elements for the credibility of our Responsible Sourcing Programme. We review auditors’ accreditation and performance annually to ensure they continue to meet our requirements.

Auditors are also required to demonstrate they fulfil the requirements detailed in our third-party guidance.
