Why these ISO standards updates matter

ISO standards updates are coming thick and fast over the next two years, and if your business relies on certification for quality, environmental or health and safety management, now is the time to pay attention. Several of the standards Irish and UK organisations lean on most including ISO 9001, ISO 14001 and ISO 45001 are either being revised or reviewed between 2026 and 2027. The changes won’t arrive overnight, but they will shape how you run audits, train staff and document your systems. This guide breaks down what’s changing, when, and what you can do today to stay ahead.

What to do now

Review your current quality manual with a critical eye. If your processes still read like they were written a decade ago, this is a good moment to modernise regardless of when the new version lands.

ISO 14001: Environmental management gets a refresh

What’s happening

ISO 14001 is under revision, with publication expected in the 2025–2026 window. (April 15, 2026) The revision is being driven in part by the “London Declaration,” ISO’s commitment to embed climate considerations across its standards.

What’s likely to change

Early drafts suggest stronger language around:

• Climate change risk and opportunity
• Lifecycle thinking and value-chain impacts
• Alignment with sustainability reporting frameworks (for example, the EU’s CSRD, which is already reshaping how Irish companies report environmental data)

What to do now

If you hold ISO 14001 certification, ask your certification body what they’re hearing about the transition period. Most ISO revisions allow two to three years to migrate but early movers tend to have a smoother ride.

ISO 45001: Occupational health and safety under review

What’s happening

ISO 45001 was published in 2018 and is now in its first systematic review cycle. A full revision hasn’t been confirmed at the time of writing, but the standard is being assessed against current workplace realities. The revision of ISO 45001:2018 has been officially confirmed by ISO/TC 283, moving it beyond the initial systematic review phase. It is currently in the early stages of a full revision with an expected publication date for the new version around 2027.

What’s likely to change

If a revision goes ahead, likely focus areas include:

• Mental health and psychological safety a major shift since 2018
• Remote and hybrid working risks
• Contractor management and complex supply chains
• Worker consultation and participation in a digital-first workplace

What to do now

Don’t wait for the revision. Mental health, lone working and hybrid-work risk assessments are already expected under existing Irish and UK health and safety law including the Safety, Health and Welfare at Work Act 2005 in Ireland and the Health and Safety at Work etc. Act 1974 in the UK. Strengthening these areas now prepares you for any future ISO 45001 changes and keeps you on the right side of current regulations.

ISO 27001 and information security: Where things stand

ISO 27001 was substantially updated in 2022. Certified organisations had until 31 October 2025 to transition to the new version, under the timeline set by the International Accreditation Forum. [VERIFY the IAF transition deadline and any extensions]

How to prepare for ISO standards updates in 2026–2027

You don’t need a crystal ball you need a plan. Here’s a practical approach:

1. Map your current certifications

List every ISO standard your business holds, along with the certification body, audit dates and internal owner. You’d be surprised how often this isn’t written down anywhere.

2. Subscribe to updates from your certification body

NSAI in Ireland and UKAS-accredited bodies in the UK regularly publish transition guidance. Sign up for their newsletters it’s the cheapest early-warning system you’ll get.

3. Build change into your internal audit plan

When a revision is published, treat it as a planned change under your management system. Review the gap, update documents, train staff, and evidence it all in your next internal audit.

4. Train your people early

Revisions often fail at the shop floor, not in the boardroom. Short, practical refresher training on risk assessment, reporting, or climate considerations pays off faster than a rewritten manual.

Frequently asked questions

When will the new ISO 9001 be published?

ISO/TC 176 has been working toward a 2026 release, though the exact date depends on committee approval. 

Do I need to re-certify when a standard is revised?

No. You transition during your normal audit cycle, usually within a two- to three-year window set by the International Accreditation Forum.

Will ISO 45001 change because of mental health awareness?

It’s widely expected that mental health, psychological safety and hybrid-work risks will feature more prominently in any future revision but your current duty of care already covers these under Irish and UK law.

Items flagged for manual review before publishing:

1. ISO 9001 publication date — confirm via ISO/TC 176 work programme.
2. ISO 14001 publication timeline — confirm via iso.org.
3. ISO 45001 — confirm whether a formal revision has been launched or if it’s still in systematic review.
4. ISO 27001 — confirm the IAF transition deadline of 31 October 2025 and any published extensions.
