Why companies switch

Let's be honest: most companies don't actively think about their certification body. You once made a choice, and since then the contract has been automatically extended. But is that smart?

Research shows that companies switch for various reasons:

  • The audit yields too little. You get a certificate, but no real insights that will help your company further.
  • The auditor lacks industry knowledge. A generic approach does not work if your sector has specific challenges.
  • The service is inadequate. Poor accessibility, inflexible planning, slow communication.
  • The price is no longer correct. Rates have risen, or you have discovered that it can be cheaper elsewhere.
  • You want to consolidate. Multiple certificates from different parties is inconvenient.

Internationally, it is even common to change certification bodies every five to ten years. Not out of dissatisfaction, but because a fresh look reveals new areas for improvement. This prevents tunnel vision.

The success of an audit depends on the auditor. Certification remains a human job. If the click is not there, you can be critical of it.

The international rules: IAF MD 2

You may be thinking: "But can I just switch? And what will happen to my certificate?"

Good questions. And the answer is reassuring.

Switching certification bodies is regulated in an international document: IAF MD 2. These are the rules that all accredited certification bodies must adhere to. The most important points at a glance:

Your certificate remains valid

No interruption during or after the transfer. Your new certification body will take over the certification within your existing cycle.

Your old CI should not be a hindrance

They are not allowed to revoke your certificate because you switch. Cooperation with the transfer is mandatory.

Your audit cycle continues

No extra audits, no duplication of work. The new certification body builds on your existing audit history.

Available at any time

You don't have to wait for your certificate to expire. Please note the notice period of your current contract (usually 4-8 weeks).

How the switch works

The practice is less complicated than you might expect. This is what happens:

The pre-transfer review

Your new certification body first looks at your file. They check your latest audit reports, any outstanding deviations and complaint history. This is called the "pre-transfer review" and is not an audit, but an administrative check.

At most companies this is a formality that can be arranged within a few days. You give permission for your current certification body to share the information, and the new party to assess whether everything is in order.

What you need

For a smooth transition, collect these documents:

  • Copy of your current certificate (with expiration date)
  • Audit reports from the last three years
  • Status of any outstanding deviations
  • Overview of complaints and how they were handled

That's it. Your new certification body will take care of the rest.

The timeline

On average, the switching process takes two to four weeks from the moment you choose a new certification body. This depends on the availability of the new auditor and how quickly the documentation is transferred.

When does switching make sense for you?

Not everyone has to switch. But it is smart to regularly evaluate whether your current situation is still suitable. Ask yourself these questions:

  • Does the audit provide you with anything? Do you gain useful insights, or does it feel like an obligatory number?
  • Does your auditor understand your industry? Or do you have to explain how your sector works every year?
  • What is the service like? Are you satisfied with the communication, planning and accessibility?
  • Is the price still correct? Have you compared with other providers in recent years?
  • Does the approach suit your company? Some certification bodies are formal and process-oriented, others personal and pragmatic.

If you answer "no" or "don't know" to several questions, it might be time to compare.

Choosing an ISO 9001 Certification body

Not every certification body is the same. The choice affects your experience and your wallet.

Accreditation: crucial

A certification body must be accredited by a recognised body. In the Netherlands this is the Dutch accreditation body, but foreign accreditations are also valid.

Recognised accreditation bodies include:

Netherlands

national accreditation body

United Kingdom

UKAS

Germany

DAkkS

Belgium

BELAC

France

COFRAC

All these bodies are members of the IAF (International Accreditation Forum). Certificates of IAF members are recognised worldwide through the MLA treaty.

Selection criteria

Accreditation

Without accreditation, your certificate may not be recognised

Industry experience

An auditor who knows your sector, understands your context

Price

Prices vary, compare at least three quotes

Accessibility

Short lines are nice for questions or problems

Reputation

Request references from similar companies

Questions to ask

When comparing certification bodies you can ask these questions:

  • Are you accredited for ISO 9001? By whom?
  • Do you have experience in my sector?
  • What is included in the price? (travel costs, preliminary consultation, reporting)
  • Who will be my permanent auditor?
  • What is the lead time until the audit?
  • How do you deal with deviations?

The right choice is not necessarily the cheapest. An auditor who understands your sector and provides constructive feedback is worth more than a few hundred euros in savings.

Questions about ISO 9001

What does ISO 9001 certification cost?

How do you get an ISO 9001 certificate?

First you build a quality management system that meets the standard. Then you engage a certification body that carries out an audit. With a positive result you receive the certificate.

Read the full answer
Is ISO 9001 certification mandatory?

No, ISO 9001 is voluntary. But some clients or sectors do require it. In construction, healthcare and government contracts it is often a condition for taking part in a tender.

Is there a new version of ISO 9001?

Yes, ISO 9001:2026 is planned for September 2026. The new version puts more emphasis on sustainability, digitalisation and quality culture. After publication you get about three years to transition.

Can I arrange ISO 9001 certification myself?

Yes, you can. Many SMEs build their quality system themselves. This saves consultancy costs (€2,000-8,000), but it takes more time. The certification audit must always be carried out by an external certification body.
