All about the Workers Allocation by Intermediaries Act.

Are you a supplier of professionals or a freelancer? Then you cannot ignore the Waadi registration. In this article, we will take you step by step. What exactly the Placement of Workers Allocation by Intermediaries Act (Waadi) requires, to whom the registration obligation applies, what fines are lurking and how you can prevent yourself from running unnecessary risks with one quick check. You can read all about the Waadi registration here!

What is the Waadi again?

The Waadi has been the legal basis for a fair temporary employment and secondment market since 1998. The law requires intermediaries who "supply personnel" to make that fact visible in the Trade Register. The aim? To prevent abuses such as underpayment, sham constructions and unfair competition. Thus, the Waadi guarantees that temporary workers are entitled to the same working conditions as permanent colleagues

Why does Waadi registration exist?

Imagine a market in which a thousand intermediaries operate, but no one can see who is working legally. Without registration, a rogue hirer could start today, place people at underpaid wages and disappear tomorrow. A Waadi listing makes every temporary employment or secondment company publicly traceable in the Trade Register. The Labour Inspectorate carries out targeted checks, and you as a hirer can see within a minute whether a partner works cleanly.

For whom is registration mandatory?

- Temporary employment agencies and agencies that place temporary staff with clients.

- Secondment and payroll companies. organisations that formally have employees on their own payroll but let them work elsewhere.

- Intermediaries and brokers. parties that "make freelancers or self-employed persons available" under the direction and supervision of a client.

- Holding company structures. As a parent company, do you offer staff from several operating companies? Even then a separate Waadi registration is required.

Are you in doubt? Apply this rule of thumb, if you offer people to perform work for someone else in return for payment, then your activity almost certainly falls under the law.

How do you do the Waadi check?

1. Go to kvk.nl/waadicheck. 

2. Enter the CoC number (or trade name) of your hirer.

3. Click on Search. 4. Under "Ancillary activities", check whether there is a tick under Provision of labour. 

No tick? Then the registration is not in order. Do not continue working until this is resolved. The Chamber of Commerce recommends carrying out the check annually.

This is how to arrange a Waadi registration yourself

1. Log in to the Chamber of Commerce and use your company's existing file.

2. Add activity and choose "Provision of labour" (SBI code 78). 

3. Pay change fees. The Chamber of Commerce charges €18 (2025 rate) for an online mutation.

4. Save confirmation. Save the pdf of the new registration because clients ask for it.

Tip: if your business model changes or if you stop broadcasting, you also need to have the Waadi endorsement removed again.

Waadi for zzp platforms and freelancers

Do you work as a freelancer via a broker or payroll construction? Check whether your broker is Waadi-registered. Although as a self-employed person you are outside employment, the law considers the broker to be a "posting party" if it places you under management and supervision. We know a lot about this; we want to protect both professionals and clients from fines. So feel free to contact us if you have any questions about anything.

Practical checklist for your organisation

Start by determining your role. Are you a hirer, user or do you perform both roles? Then check your CoC registration to make sure that the activity "Supply of labour" is clearly stated. Documenting checks is also important. Therefore, always keep proof of every Waadi check carried out. Also take the time to update your contracts with explicit references to equal employment conditions.

Also, make sure your HR and sales team is well trained so that everyone knows exactly when registration is required. Finally, it is wise to include a six-monthly reminder in your compliance calendar, so that you regularly check that everything still complies with current regulations. With these steps, you reduce the risk of sanctions and show clients that your organisation is transparent and reliable.
