Why Halderstone

Our approach

  • Audit planning informed by risks, objectives, and the intended use of audit results

  • Audit activities aligned with recognized auditing principles and guidance, including ISO 19011 where appropriate

  • Findings based on objective evidence obtained through interviews, documentation review, observation, and sampling

  • Conclusions supported by corroboration across multiple evidence sources and audit methods

  • Practical reporting focused on decision-making, assurance, and continual improvement

What we deliberately do not do

  • Mandates that compromise auditor independence

  • Audit engagements where we influence the selection of samples, evidence, or interview partners

  • Conclusions based solely on interviews without corroborating evidence
