ISO 9001:2026 changes: transition guide for your QMS

ISO 9001 is the world's most widely implemented quality management standard: more than one million organisations in 170 countries work with it. The current version, published in 2015, has been in force for over ten years and its official update will arrive in September 2026. The international draft (DIS, Draft International Standard) was published on 27 August 2025 and achieved a 97% approval rate among ISO national member bodies. The message is clear: the changes are measured, not a revolution — but there are specific clauses affecting management, risk management and environmental context, and certified companies need to understand them now to avoid managing the transition under pressure.

In this article we break down every relevant modification, explain when the new standard comes into force and what steps you need to take so that your management system is ready for the transition audit. If you would like an expert team to guide you through this process, our ISO 9001:2026 transition service covers everything from gap analysis to the certification audit with the leading accredited bodies.

Status of the revision process: official timeline

The ISO 9001 standard is reviewed periodically according to ISO rules: a systematic review is carried out every five years and, when appropriate, a formal amendment or full revision process is opened. The current cycle started in 2022 with a systematic review survey that confirmed the need to update several sections, particularly to incorporate Amendment 1:2024 on climate change and to align the standard with the new Harmonised Structure (HS, formerly known as Annex SL) shared by all ISO management system standards.

The expected transition period is three years from the official publication date (subject to confirmation by the International Accreditation Forum, IAF). This means that certificates issued under ISO 9001:2015 will remain valid until approximately September 2029, after which all certified organisations will need to have completed their transition to the new version.

ISO 9001:2026 key changes clause by clause

The good news for organisations that have been working with a mature management system for years is that the changes to the requirements clauses (4 to 10) are surgical, not structural. Most modifications are concentrated in the introductory material and in a significantly expanded Annex A that provides more detailed guidance without adding mandatory requirements. That said, there are three areas that do generate new obligations or binding clarifications:

Clause 4.1 — Context of the organisation: climate change enters the standard

Amendment 1 of 2024 added a note to clauses 4.1 and 4.2 stating that the organisation shall determine whether climate change is a relevant issue for its context. This amendment, published in February 2024, is now structurally incorporated into the ISO 9001:2026 text. In practice, this means that during the context analysis — which any certified company already carries out — you will need to explicitly document whether climate change (extreme weather events, energy transition, emissions regulations, physical risks in the supply chain) affects your ability to deliver conforming products or services. No decarbonisation plan is required, but an explicit relevance assessment is.

Clause 5.1 — Leadership: quality culture and ethical behaviour

This is one of the most visible changes for top management. Clause 5.1 introduces as a new explicit requirement that management must actively promote a culture of quality and ethical behaviour within the organisation. Until now, leadership commitment was demonstrated primarily through measurable actions (resource allocation, policy communication, management review…). With the new version, management will need to be able to evidence how it fosters values of integrity and quality in the organisational culture — this may take the form of codes of conduct, recognition programmes, values training or internal feedback mechanisms.

Clause 6.1 — Planning: risks and opportunities separated

One of the most common points of friction in ISO 9001:2015 audits has been the combined treatment of risks and opportunities in a single sub-clause. The 2026 revision introduces a clearer separation, creating differentiated sub-clauses (6.1.1 to 6.1.3) for each concept. This does not change the underlying philosophy — thinking about what can go wrong and what can go right — but it does require both to be documented independently. Organisations that have mixed both in a single risk/opportunity table will need to review and update their methodology.

Expanded Annex A — Guidance, not additional requirements

Annex A of ISO 9001:2026 expands considerably with clarifications on the requirements of clauses 4 to 10. This is informative, not normative, material — but reading it is strongly recommended because it anticipates how auditors will interpret requirements. In particular, the annex clarifies concepts related to organisational knowledge management, determination of the scope of the system, and integration of quality with other management systems (environmental, occupational health and safety, etc.).

What does NOT change in ISO 9001:2026?

For those who have a well-built management system, the reassuring news is: the high-level structure (clauses 4 to 10), the process approach, the PDCA cycle (Plan-Do-Check-Act) and the quality management principles remain intact. No new requirements chapters are added. The logic of strategic planning, operational control and continual improvement is unchanged. The adaptation effort for a company with a mature and well-documented system should be moderate.

How to plan the transition step by step

Although the official three-year period may seem long, the experience accumulated in the transitions from ISO 9001:2008 to 2015 and from ISO 14001:2004 to 2015 shows that organisations that wait until the final year concentrate the effort, generate internal tension and in some cases lose their certificate for failing to complete the transition audit with their certification body on time. The recommendation from Summum Calidad — with more than 200 ISO certifications accompanied since 2007 — is to start the gap analysis in the second half of 2026, as soon as the final standard is published.

Phase 1 — Gap analysis

Compare your current system with the new requirements. Identify specifically whether your context analysis documents climate change, whether you have evidence of management's commitment to a quality culture and ethics, and whether your risk and opportunity records are sufficiently differentiated. The result is a prioritised list of actions by impact and effort.

Phase 2 — Document update

Review and update the affected system documents: context analysis (4.1), interested parties register (4.2), quality policy (5.2), risk and opportunity management methodology (6.1) and the scope of the QMS (4.3). Most changes are additions or clarifications to existing documents, not new documents.

Phase 3 — Training and implementation

Train process owners on the new requirements. Pay particular attention to management, who need to understand what evidence they must provide to demonstrate that they promote a quality culture and ethical behaviour. This phase also includes the practical application of changes to operational processes.

Phase 4 — Internal audit and management review

Before the transition audit with the certification body, carry out at least one full internal audit under the new version and a management review that covers the new inputs. This allows deviations to be detected and corrected before an external auditor finds them.

If you want to manage this process with an external consultant who knows the criteria of the leading certification bodies (AENOR, Bureau Veritas, SGS, TÜV…), our ISO 9001:2026 transition team is available from any of our five offices: Valladolid, Burgos, Palencia, Aranda de Duero and Las Palmas.

ISO 9001:2026 and other standards: impact on integrated management systems

Many organisations run integrated management systems combining ISO 9001 (quality) with ISO 14001 (environment) or ISO 45001 (occupational health and safety). The good news is that all these standards share the Harmonised Structure and that the incorporation of climate change into ISO 14001:2015 was already carried out via a parallel amendment in 2024. Therefore, if your company has already updated its environmental context analysis to reflect climate change, the additional effort for ISO 9001:2026 will be minimal: you will simply need to replicate that logic in the quality management system.

For companies in the agri-food sector working with ISO 22000 or IFS/BRC, integration with sustainability requirements is also relevant, as major European retailers are incorporating ESG criteria into their supplier audits. ISO 9001:2026 reinforces this trend.

Frequently asked questions

Will my ISO 9001:2015 certificate still be valid when the new standard is published?

Yes. Once ISO 9001:2026 is published (expected September 2026), certificates issued under the 2015 version will continue to be valid during the transition period, estimated at three years (until approximately September 2029). After that deadline, 2015 certificates will no longer be recognised by accreditation schemes. Your certification body will inform you of the exact dates and the procedure for requesting the transition audit.

Will I have to repeat the full certification audit or is a transition audit sufficient?

There is no need to repeat the full certification process. Accredited bodies (AENOR, Bureau Veritas, SGS, TÜV, DNV…) will carry out transition audits — surveillance or renewal audits in which the auditor specifically verifies the changes introduced by the new version. Their duration is significantly shorter than an initial certification audit. Most bodies will integrate the transition into the next surveillance or three-year renewal audit.

Is climate change now a mandatory requirement in ISO 9001:2026?

Yes, in the sense that you must determine whether it is relevant to your organisation and document that determination. There is no requirement to reduce emissions or implement a climate action plan (that falls under ISO 14001 or ISO 14064 for carbon footprint). What the standard requires is that the context analysis process explicitly considers whether climate change — in any of its dimensions: physical, regulatory, reputational — may affect the organisation's ability to deliver conforming products or services. If you conclude that it is not relevant, you must be able to justify that conclusion.

How long does it take to adapt an existing management system to ISO 9001:2026?

For an organisation with a mature, well-documented management system and no major non-conformities in recent surveillance audits, the estimated adaptation effort is between four and eight weeks of internal work, plus the time for the transition audit with the certification body. The factor that most often extends the process is updating the context analysis and gathering evidence of quality culture from management. Organisations with less mature systems or out-of-date documentation may need between three and six months of preparatory work before being ready for the transition audit.
