Updated October 2026. Global Accreditation Cooperation (Global ACI) has confirmed that organisations certified to ISO 9001:2015 must transition by 30 September 2029. For the full timeline and a phased approach, see our ISO 9001:2026 transition plan.
ISO 9001 is the world’s most widely used management system standard, and on 16 September 2026 ISO published its sixth edition. If you hold ISO 9001:2015 certification, are working towards it, or are simply trying to separate fact from sales talk, this article sets out what has actually changed, what has not, and how to plan a sensible transition.
The short version
ISO 9001:2026 is now the current edition. It replaces ISO 9001:2015 as the version organisations will certify against.
It is an evolution, not a rebuild. The ten-clause structure, the process approach and the great majority of requirements are unchanged. A well-run 2015 system will not need to be rewritten.
Your 2015 certificate remains valid during the transition. The transition deadline is 30 September 2029, but confirm audit arrangements and timing with your certification body.
A quick reminder of what ISO 9001 is
ISO 9001 sets out the requirements for a quality management system: the way an organisation plans, runs, checks and improves the work that determines whether customers get what they need. It does not prescribe a particular way of working. Instead, it requires you to understand your context, manage risk, control your processes, measure results and improve continually, with independent certification available to demonstrate that you do.
Like ISO 14001, ISO 45001 and ISO 27001, it follows the Harmonized Structure, the successor to the High Level Structure, which is why these standards integrate so well into a single management system.
What has changed
Quality culture and ethical behaviour (Clause 5.1). Top management must now actively promote a quality culture and demonstrate ethical behaviour. This is the most significant change, because it cannot be satisfied by a revised policy statement alone. Auditors will look for evidence in decisions, communications and behaviour.
Risks and opportunities separated (Clause 6.1). Risks and opportunities are now determined and evaluated as two distinct requirements. Many organisations recorded opportunities as an afterthought in a risk register. That approach will need to change.
Planning of changes strengthened (Clause 6.3). Changes to the management system must be planned with clear measures of effectiveness, then communicated, monitored and reviewed. In practice this means a visible, closed-loop change process.
Climate change in context (Clauses 4.1 and 4.2). The 2024 climate amendment is carried forward, so you must consider whether climate change and sustainability are relevant issues for your organisation and its interested parties.
Awareness and knowledge (Clauses 7.3 and 7.1.6). Awareness now extends to quality culture and ethics, and organisational knowledge must be retained, applied and shared.
Customers and external providers (Clause 8). Operational requirements change little, but customers should be informed of relevant contingency plans, and external providers must be managed against customer and interested-party requirements, not just technical specifications.
Leadership in improvement (Clause 10). Leadership’s role in driving improvement is more explicit. Corrective action records alone will no longer tell the full story.
A new Annex A. For the first time, ISO 9001 includes substantial guidance on how to interpret the requirements. It is not auditable in itself, but it is the best first reference when a clause’s intent is unclear.
What has not changed
The fundamentals remain: understanding your context and interested parties, the process approach, documented information, operational control, internal audit, management review, nonconformity and corrective action. If those are working well today, your transition is a focused update rather than a project.
What auditors are likely to look for
In our experience, the organisations that struggle with a new edition are those that treat it as a documentation exercise. Expect auditors to ask how leadership actually influences quality culture, to look for genuine opportunities with owners and actions, and to follow a recent change through from planning to review. Evidence that the system is used will matter far more than new wording.
How to plan your transition
- Talk to your certification body. Confirm when it will audit against the 2026 edition and how the transition audit will be handled.
- Run a gap analysis. Prioritise the major changes in Clauses 5.1, 6.1 and 6.3, then the moderate ones.
- Update leadership evidence. Revise your quality policy and decide how leaders will visibly promote culture and ethics.
- Restructure your risk and opportunity register so that each is identified and evaluated separately.
- Formalise change planning with a simple plan, communicate, monitor and review loop.
- Brief your internal auditors and update audit checklists to the 2026 requirements.
- Complete an internal audit and management review against the new edition before your transition audit.
For the confirmed transition dates, a phased plan and the evidence auditors will expect, see our ISO 9001:2026 transition plan. If you hold more than one certification, our overview of the 2026 standards transitions shows how ISO 9001, ISO 14001, IA9100 and ISO 45001 fit together.
If you also hold ISO 14001, note that ISO 14001:2026 was published on 15 April 2026. Planning both transitions together, within an integrated management system, avoids duplicated effort and a second round of change.
If you are not yet certified, build your system to the 2026 edition from the start. Our guide to the ISO 9001 certification process explains the steps.
