ISO 19011:2026 – What Changed from ISO 19011:2018?

Changes in ISO 19011 2026ISO 19011:2026, Guidelines for auditing management systems, was published on 27 May 2026 as the fourth edition of the international auditing guideline, replacing ISO 19011:2018. For organisations that conduct internal audits, supplier audits or other management-system audits, the revision does not require a complete redesign of the auditing process.

The familiar principles of auditing and the basic flow of planning, conducting, reporting and following up audits remain. What has changed is the environment in which audits are expected to operate: remote working, virtual locations, digital evidence, emerging technology, information-security concerns and increasingly complex supply chains now receive much more practical attention.

ISO 19011:2026 is an evolution, not a completely new audit model

The first point to understand is that ISO 19011:2026 is a technical revision. Organisations that already have a mature internal audit programme based on ISO 19011:2018 should not interpret the new edition as a reason to discard their existing audit procedure, formats or established practices.

ISO itself identifies the major changes as the expansion of guidance on remote auditing methods, incorporating concepts from ISO/IEC TS 17012:2024, and the expansion of Annex A to address remote auditing methods and virtual locations. Professional auditing guidance published by CQI/IRCA also identifies several detailed refinements relating to audit programme management, technology, risks, auditor competence, supply-chain auditing and audit findings.

The practical question, therefore, is not “Do we need a completely new audit system?” It is “Which parts of our existing audit programme need to be updated so that they reflect how organisations actually operate in 2026?”

ISO 19011:2018 vs ISO 19011:2026 – key changes at a glance

Area ISO 19011:2018 approach What is clearer or stronger in ISO 19011:2026
Remote auditing Remote techniques were recognised, mainly through additional guidance. Remote auditing is formally defined and more deliberately integrated into audit programme planning and audit execution.
Virtual locations Considered, but with less developed guidance. Audit scope explicitly accommodates physical and virtual locations.
Technology Technology-supported auditing was possible but less prominent. Digital tools, ICT, emerging technology and their effect on audit effectiveness receive greater consideration.
Audit programme risk Risks and opportunities were already addressed. Risks and opportunities are expected to be determined and evaluated more deliberately, including risks arising from audit methods, information security, resources and undue influence.
Auditor competence Competence focused on audit skills, management systems and relevant disciplines. Competence considerations extend more clearly to emerging technology, technology-enabled auditing, data protection and information security.
Supply-chain audits Supplier and external-provider auditing was addressed. Annex A provides more substantial guidance for supply-chain and second-party auditing.
Audit findings Established guidance for findings and nonconformities. Additional emphasis is placed on clearly recording why audit criteria were not fulfilled and, where applicable, the agreed grading of nonconformities.

1. Remote auditing is now built more clearly into the audit framework

Remote auditing is the most visible change. ISO 19011:2026 introduces a specific definition of a “remote auditing method” in Clause 3.4. It covers audit activities carried out from a location other than the auditee’s location and recognises that remote and on-site methods can be combined to achieve an effective audit.

This matters because remote auditing should no longer be treated simply as an emergency substitute for visiting a site. The method should be consciously selected based on the audit objectives, availability of evidence, risks, technology, confidentiality requirements and the nature of the activities being audited.

For example, reviewing a cloud-based document management system, interviewing a process owner through video conferencing or remotely viewing records may be perfectly effective. Verifying machine guarding, chemical storage conditions, housekeeping or emergency access routes may still require physical presence. The auditor’s judgement about the method therefore becomes important.

2. Audit scope can include virtual as well as physical locations

A related change is the clearer recognition of virtual locations. ISO 19011:2026 explains that the audit scope can include both physical and virtual locations. A virtual location exists where work or services are performed through an online environment rather than being tied to a specific physical workplace.

This is particularly relevant to software organisations, shared-service centres, remote teams, cloud-based operations, professional-service firms and organisations with employees working from multiple locations.

An internal audit programme should therefore avoid assuming that “location” always means a building. Auditors may need to follow processes through cloud applications, workflow platforms, remote access arrangements, digital approvals and electronically maintained records.

3. Technology, information security and organisational context matter more when planning audits

Clause 5 guidance now places more visible attention on the auditee’s context, use of technology and digital tools, as well as information-security and confidentiality requirements when developing the audit programme. The programme should also identify the auditing methods to be used, including remote methods.

This has a very practical implication. An annual audit calendar based only on departments and dates may no longer be sufficient for a complex organisation. When deciding audit frequency, duration, method and auditor competence, the audit programme manager should understand how the organisation actually operates.

A process heavily dependent on automated systems, outsourced platforms or remote operations can require a different auditing approach from a conventional manually controlled process.

The revised guidance also recognises consideration of whether climate change is a relevant issue for the auditee when designing the audit programme, consistent with the broader climate-related changes made to ISO management-system standards. The point is not to insert climate questions mechanically into every audit, but to consider the issue where it is relevant to the organisation and the management system being audited.

4. The risk-based approach becomes more deliberate

Risk-based auditing was already one of the seven principles in ISO 19011:2018, so risk thinking itself is not new. The 2026 edition strengthens how this principle is translated into the management of the audit programme.

Among the risks that can affect an audit programme are inadequate resources, insufficient auditor competence, inappropriate audit methods, ineffective communication, loss of independence or impartiality, poor protection of audit information, lack of leadership support, difficulty obtaining audit evidence and insecure information and communication technology.

There is also greater emphasis on protecting the integrity of the audit programme against undue influence. This is important in internal auditing. An audit programme should not be casually altered because a department does not want to be audited, a manager wants the scope narrowed or an inconvenient audit is repeatedly postponed.

In practice, organisations should be able to explain why higher-risk, lower-performing or strategically important processes receive appropriate audit attention rather than merely showing that every department was audited once during the year.

5. Auditor competence now has to keep pace with emerging technology

One of the most relevant changes for practising auditors concerns competence. The revised guidance recognises that auditors may need to understand emerging technology from two different perspectives: technology may be part of the process being audited, and technology may also be used by the auditor to conduct the audit.

CQI’s review of the revised standard specifically highlights competence considerations relating to emerging technology, including artificial-intelligence-based evaluation tools, together with greater awareness of data protection and information-security requirements.

This does not mean that every management-system auditor now has to become an AI specialist or cybersecurity engineer. It does mean that an auditor should not use a technology-driven audit technique without understanding its limitations, and should have sufficient competence to meaningfully evaluate a technology-dependent process within the scope assigned to them.

For organisations, auditor competence matrices may therefore need updating. Training and experience should reflect not only the management-system standard being audited but also the technologies, processes and auditing methods relevant to the assignment.

6. Supply-chain and second-party auditing guidance has been strengthened

Organisations increasingly rely on suppliers, outsourced processes, cloud providers, logistics partners, contractors and other external organisations. ISO 19011:2026 responds by substantially expanding the Annex A guidance relating to supply-chain audits and particularly second-party auditing. CQI identifies this as one of the more significant Annex A developments.

This is useful for organisations that conduct supplier audits because a second-party audit should not simply copy an internal audit checklist. The audit purpose may be to evaluate supplier capability, verify contractual controls, investigate repeated performance issues, assess risk before approval or obtain confidence in controls that the purchasing organisation depends upon.

The audit objectives, competence required, sampling and evidence should therefore reflect the reason for auditing the supplier.

7. Audit findings and nonconformities should be more clearly supported

Annex A also provides additional guidance around audit findings. Where a nonconformity is raised, auditors are reminded to record why the applicable audit criteria were not met. If nonconformities are graded under an agreed system, the grade should also be recorded appropriately.

This supports a basic but sometimes overlooked principle of good auditing: a nonconformity should be traceable from the requirement to the objective evidence and then to the identified failure to fulfil that requirement.

Statements such as “procedure not followed”, “system inadequate” or “records need improvement” are not strong audit findings unless the requirement, evidence and nature of the failure are clear.

What has not changed in ISO 19011:2026?

Despite the revisions, the fundamentals of good management-system auditing remain familiar. The seven auditing principles continue: integrity, fair presentation, due professional care, confidentiality, independence, evidence-based approach and risk-based approach. The overall framework covering management of the audit programme, conducting an audit and evaluating auditor competence also remains recognisable.

An organisation with a sound ISO 19011:2018-based process therefore does not need to generate unnecessary procedures and forms simply because the edition number changed. The better approach is to perform a focused gap review and update only what is materially affected.

What should organisations update now?

For most organisations, a practical ISO 19011:2026 update can focus on the following areas:

  • Review the internal audit procedure and audit programme for references to ISO 19011:2018.
  • Define how on-site, remote or combined auditing methods are selected.
  • Ensure virtual locations and digitally operated processes are not unintentionally excluded from audit scope.
  • Review audit-programme risks, including ICT security, confidentiality, auditor availability, independence, evidence availability and management influence.
  • Update auditor competence criteria where emerging technology, remote auditing or information-security knowledge is relevant.
  • Review second-party or supplier-audit methodology where such audits form part of the programme.
  • Check that audit findings clearly link criteria, evidence and the reason for non-fulfilment.
  • Review audit checklists, training materials and auditor guidance rather than automatically replacing established forms that continue to work effectively.

Does ISO 19011:2026 have a transition deadline?

ISO 19011 is a guidance standard, not a management-system requirements standard against which organisations obtain ISO 19011 certification. ISO confirms that using ISO 19011 does not itself lead to certification. CQI/IRCA consequently notes that the revised auditing guidance applies from publication rather than having the type of multi-year certification transition period normally associated with a revised certifiable standard.

This should not be confused with transition requirements for standards such as ISO 9001, ISO 14001, ISO 45001 or ISO/IEC 27001. Certification bodies also operate under conformity-assessment requirements such as ISO/IEC 17021-1 and relevant accreditation and scheme requirements; ISO 19011 serves as useful auditing guidance rather than replacing those requirements.

What ISO 19011:2026 means in practical terms

The real message of ISO 19011:2026 is that auditing practice needs to reflect the organisation being audited. Processes no longer exist only inside factories and offices. Evidence may sit in cloud platforms, activities may be performed remotely, suppliers may operate across different countries, and decisions may increasingly depend on automated or technology-enabled systems.

At the same time, the fundamentals have not changed. A good auditor still needs to understand the criteria, follow the process, obtain reliable evidence, exercise professional judgement and reach conclusions objectively.

The 2026 revision therefore provides a good opportunity to review an organisation’s audit programme without creating unnecessary documentation. The objective should be a more effective audit process — not simply more forms.
