The conversation to have with your certification body

A question that now has an answer

Until this month, if you rang your certification body to ask when you had to transition to ISO 9001:2026, you got one of three responses: a confident date, a careful non-answer, or an offer to call you back. The careful non-answer was the correct one.

That has changed. The dates are now public, and it is worth understanding who set them, because the date that matters to you is still not the one in the announcement.

Who decides what

ISO publishes the standard. It did so on 16 September 2026, and ISO 9001:2015 is now withdrawn.

ISO/TC 176, ISO's quality management committee, has announced the transition arrangements. Existing ISO 9001:2015 certificates have until 30 September 2029 to transition. From 31 March 2028, new certifications may only be issued to the 2026 edition.

Your certification body schedules your audits inside that window. It controls your dates. It does not control the window, but it is the only party that can tell you when your transition audit falls.

So the question is no longer when the deadline is. It is which of your audits carries the transition.

Why a known deadline changes less than it seems

The temptation, reading the above, is to treat 2029 as distant. That is the wrong conclusion, because the decision never depended on the window.

You have a recertification or surveillance visit already in the diary. Either you transition at a visit you were always going to have (one project, one disruption, one round of leadership attention), or you recertify to the outgoing standard now and run the whole exercise again later, before the window closes.

The second path costs more and buys nothing except a delay.

Four questions worth asking instead

Skip when is the deadline. Ask these:

1. When is my next recertification, exactly? Not the year — the month. Most people are vague about this and it is the number the whole decision turns on.
2. Can that visit be conducted against the 2026 standard, and from what date will your assessors be able to do so? Certification bodies must have their own accreditation extended before they can transition anyone. Their readiness is a real constraint and it is a fair question.
3. If I want to move my audit date, how much notice do you need? Worth knowing before you need it, because assessor availability tightens sharply as the end of a transition window approaches and everyone moves at once.
4. What will you want to see for the culture, ethical behaviour and awareness requirements? Their answer tells you how prepared they are. If it is vague, plan on the assumption that early assessments will be inconsistent, and keep a stronger record than you think you need.

One thing to do this quarter

Write down the month of your next recertification. Subtract nine months — the realistic time for behaviour change to become visible in a record.

If the answer is a month that has already passed, the transition is not a future project. It is the present one, and the useful conversation with your certification body is about moving the date, not about the deadline.

That conversation is much easier to have now than it will be when everyone else is having it.
