ISO 9001:2026 explained: key changes, timeline and how to prepare
ISO 9001 has been the benchmark quality management system (QMS) standard for decades. If you’re already certified or working towards it, you’ve probably seen the chatter about the ISO 9001:2026 revision.
A revision is coming… and while it’s nowhere near the overhaul that 2015 brought, there’s enough there that you’ll want to understand it before your next ISO 9001 audit or recertification.

What is ISO 9001?
ISO 9001 is an internationally recognised standard for quality management systems (QMS). Published by the International Organisation for Standardisation, it gives organisations a framework for consistently delivering products and services that meet customer, legal and regulatory requirements, with built-in processes for continual improvement. It forms the foundation for consistent quality assurance, compliance management and continual improvement across organisations.
First published in 1987 and significantly revised in 2015, it is sector-agnostic. Manufacturers, professional services firms, healthcare providers, tech companies, and public sector bodies all use it. More than one million organisations in over 170 countries hold certification.
The 2015 version moved ISO 9001 onto the Annex SL high-level structure, in other words, the same clause architecture that ISO 27001, ISO 22301, ISO 14001 and the recently published ISO 42001 use. That’s what makes integrated management systems genuinely workable rather than just in theory. ISO 9001:2026 keeps that structure intact.
What’s changing in ISO 9001:2026?
The Draft International Standard (DIS) for the ISO 9001 update landed in August 2025, and it is clearly an evolutionary update rather than a fundamental overhaul. What the revision does is tighten up some ambiguities, embed a few things that were previously implied, and add one genuinely useful new element. Overall, this ISO 9001 revision focuses on clarity, consistency and practical implementation rather than structural change.
Quality, culture and ethical behaviour
This is the change getting the most attention. Clause 5.1 picks up a new requirement for senior leaders to actively promote quality culture and ethical behaviour, not just endorse them on paper.
What auditors will actually look for: training records, evidence of internal communications, and examples of leadership doing something visible rather than just signing a policy. It doesn’t need to be elaborate. A documented management review discussion about cultural values and how they are reinforced will be sufficient for most organisations. What it can’t be is nothing.
Clause 7.3 carries the same theme into employee awareness. Employees and other relevant interested parties will be expected to understand quality culture and ethical behaviour as part of their general QMS awareness. This will need to feed into induction content, refresher training, and how you communicate internally. This reflects a broader shift towards embedding ethical behaviour and organisational culture within quality management systems.
Climate change and sustainability
This one was already required. ISO published an amendment to ISO 9001:2015 in February 2024, making it mandatory to consider whether climate change is relevant to your context. The 2026 revision formally incorporates that into the standard body under Clause 4, so it is no longer a separate document to track.
This aligns ISO 9001 more closely with broader sustainability requirements and regulatory expectations.
If you haven’t updated your context analysis yet, that is the first thing to address – it is already overdue under the current standard. This isn’t asking your QMS to become an environmental management system. It’s asking you to consider whether things like extreme weather events, climate-linked supply chain disruption, or changing sustainability regulations actually affect your operations.
For many organisations, the answer will be yes in at least one area. Ask yourselves how you may contribute to limit the impact of climate change: this could be by allowing staff to work from home, thus reducing commuting, limiting client and supplier visits in favour of online meetings, replacing hardware when required rather than according to a set schedule, and generally maximising recycling opportunities.
Clearer risk and opportunity management
Clause 6.1 is getting sub-clauses. Currently, risks and opportunities sit together in a single combined clause. The 2026 structure separates them, which should make documentation and audit evidence cleaner. In other words, you can address each on its own terms rather than trying to shoehorn both into one register entry.
The underlying intent is unchanged. The change is structural, and it’s a sensible one. It is expected that this change will be carried over to other standards.
A new Annex A
ISO 9001 gets its first informative annex. It is around 15 pages of supplementary guidance on terminology, structure, and clause interpretation. Effectively, this makes up the implementation notes that experienced practitioners have previously had to piece together from separate ISO publications or consultancy guidance.
For organisations already running a mature QMS, it is a useful addition. For those earlier in the journey, it removes some genuine ambiguity in the 2015 text.
Terminology tidying
A handful of QMS-specific terms that previously required cross-referencing ISO 9000 are now built directly into the standard. This should mean less jumping between documents, which is always a nice thing. The Harmonised Structure alignment is preserved, which matters if you’re running ISO 9001 alongside other management systems.
When does ISO 9001 change to ISO 9001:2026?
The current timeline:
- August 2025 — DIS published
- Early 2026 — Comment resolution and Final Draft International Standard (FDIS) preparation
- March 2026 (expected) — FDIS published (at time of writing, this still isn’t published, but we’d expect it to be soon)
- October/November 2026 (targeted) — Final standard published
- Late 2029 (expected) — Transition period ends. Note that you can expect that Certification Bodies are likely to stop certifying against the current standard from mid- to late 2028 – to be confirmed.
Three years from publication is the standard transition window. Your ISO 9001:2015 certification stays valid until that deadline. BSI and other certification bodies have indicated that the requirements are largely settled at DIS stage, so there’s no reason to sit on your hands waiting for the FDIS before starting to plan.
How to prepare for the ISO 9001 changes
If you’re already certified
Nothing urgent. Your certification is valid, and the transition period is long. But the organisations that handle these transitions without drama are invariably the ones that don’t treat them as a last-minute sprint.
The 2024 climate amendment is the most immediate gap to check. If it hasn’t fed into your Clause 4.1 and 4.2 documentation yet, that’s the first thing to address – it’s already required under your current certificate scope after all!
The quality, culture, and ethics requirements are worth thinking about now rather than later. These aren’t things you can retrofit quickly with a policy update. They depend on leadership actually doing something visible, and on employees being able to point to concrete examples. Start the internal conversation now about what that looks like in your organisation.
On risk and opportunity documentation: if your current register conflates the two without any real distinction, it’s worth separating them before Clause 6.1 restructuring makes it obvious in an audit that you haven’t yet done so. Not a major lift, but easier done in calm than under audit pressure.
If you’re not yet certified
Don’t wait for 2029. ISO 9001:2015 is fully supported, there’s a mature network of auditors and certification bodies behind it, and the transition to the updated standard will be significantly more manageable if you already have a working QMS rather than starting from scratch against a new version. The 2008-to-2015 transition was a genuine structural overhaul. This one isn’t.
Remember that Certification Bodies will stop issuing certificates against the current standard way before the end of the transition date.
For integrated management systems
If ISO 9001 sits alongside ISO 27001, ISO 14001, ISO 42001 or ISO 22301 in your management system, the Harmonised Structure alignment in the 2026 revision is good news. Any work you do refreshing your context analysis for ISO 9001:2026 should probably feed across to your ISMS and BCMS at the same time – same inputs, less duplicated effort.
