How to compare certification bodies

20 December 2025 | 2 min. read

Compare certification bodies independently by standard, sector, location and approach.

There are around 50 certifiers active in the Netherlands. They offer the same ISO standards, but differ considerably in price, approach and expertise. Yet for most companies it is a mystery which one is right for them. CertificeerWijzer is changing that.

The problem: an opaque market

Suppose you want to become ISO 9001 certified. Or ISO 27001, or NEN 7510. You google around and find dozens of providers. They all promise quality, reliability and “care-free”. But what are the real differences?

What does it cost with certifier A versus B?
Who has experience in your sector?
Which one suits a small company, which one suits a multinational?

This information is difficult to find. Certifiers rarely publish their rates. Comparisons do not exist. And when you call for a quote, you get a sales pitch.

info

Market research shows that many companies do not know how many certifiers there are in the Netherlands, let alone what the differences are.

What CertificeerWijzer does

CertificeerWijzer collects information about all active certifiers in the Netherlands and makes it comparable. No sales pitches, no “contact us for a quote”. Simply: these are the facts.

Think of us as the Independer for certification. We do not work for a certifier. We have no interest in your choice. This allows us to be honest.

On the platform you will find:

All certifiers in the Netherlands at a glance
Which standards they certify (ISO 9001, ISO 27001, VCA, and more)
Filters to search by sector, company size or standard
Practical information about what certification costs and how it works

Who is this for?

CertificeerWijzer helps two groups:

Starters - You want to certify for the first time and are looking for an overview. Which certifiers are there? What are the differences? What should you pay attention to?

Changers - You already have a certifier but are not satisfied. You want to know what alternatives there are and how switching works.

tip

Switching certification bodies is usually possible without a new initial audit. Your new certification body takes over the certificate. Read more on our switch page.

Why independent?

Certifiers do not pay us for a higher position or better rating. We only earn when you contact a certifier via our platform. And then it doesn’t matter to us which one you choose.

This means:

We also mention disadvantages of certifiers
We’ll be honest if certification may not be the best choice for your situation
We don’t indicate a “best choice” because it depends on your company
