Bemiddelingskosten: Why That €400 'Contract Fee' Is Probably Illegal

I talk to a lot of internationals moving to Amsterdam, Utrecht and Den Haag, and there's one sentence I hear in almost every onboarding call: "The agent is asking for a contract fee — is that normal?"

No. It's not normal. In most cases, it's illegal.

The Dutch Supreme Court settled this in 2015. If a rental agency is acting for the landlord — and they almost always are, because they're the one who posted the listing on Funda, Pararius or Kamernet — they cannot charge you, the tenant, a mediation fee. It doesn't matter if they call it bemiddelingskosten, administratiekosten, contractkosten, sleutelgeld, inspection fee or a "one-off service charge." The rule (Article 7:417 lid 4 of the Burgerlijk Wetboek) forbids an agent from serving two masters and billing both.

The ACM, the Dutch consumer regulator, has been crystal clear: the label on the invoice is irrelevant. If the agent works for the landlord, you owe nothing for the mediation.

And yet users forward me invoices every week for €250, €400, sometimes a full month's rent plus 21% VAT. One I saw recently: €1,500 + BTW, which is €1,815, dressed up as "contract and administration." That's not a moving cost. That's a transfer from a tenant who didn't know the rules to an agency that was betting they wouldn't.

The housing shortage does the agency's work for them. When you've been outbid on seven places in Amsterdam and an agent finally says yes, you don't argue about a €350 line item. You sign.

Woonbond, the national tenants' union, says roughly one in twelve complaints they receive is about illegal commission fees — and they consider that the tip of the iceberg because expats and international students rarely report. The ACM has had to publicly force specific agencies — Domica Eindhoven, Goeth Vastgoed, Max Property Rentals — to stop, with penalty payments attached. Those are just the ones who got caught.

The other problem is that nobody is out there hunting violators. Enforcement is complaint-driven. The Huurcommissie, which most tenants know for rent disputes and the huurprijscheck, does not handle agency-fee claims at all. Your only real recourse after the fact is civil court, or a "no cure no pay" lawyer who takes a cut.

So the practical lesson is: challenge it before you pay, not after. Once the money leaves your account you're suddenly the one chasing.

There is exactly one situation where a Dutch agent can legally charge the tenant, and it is narrow.

You — the tenant — hire the agency on an exclusive search mandate to find you a property that is not already in their portfolio and where they do not represent the landlord in any way. There has to be a written agreement between you and them, signed before any searching starts, describing the service you asked for. The fee has to be for that search work, not bundled into the rental contract.

That's it. That's the carve-out.

If the property was listed on Pararius, Funda, Kamernet, or on the agency's own website — the agent is working for the landlord. If the agent showed you around, handed you the keys, drafted the huurcontract on their letterhead — they're working for the landlord. Charging you on top is the "two masters" problem the law specifically bans.

Relocation consultants hired and paid by your employer are a different story — that's a B2B arrangement and doesn't touch this rule. But a random agent in Rotterdam asking you for €495 "administration" after you replied to their online ad? That invoice does not survive ten minutes in front of a judge.

Before you transfer anything, ask the agent in writing — email, WhatsApp, whatever leaves a paper trail — two questions:

1. "Are you acting on behalf of the landlord for this property?"
2. "Where was the property advertised?"

If they advertised it on Pararius or Funda, the answer to question one is yes whether they admit it or not. Save the original listing — take a screenshot with the URL and date visible. Agencies pull listings down fast once a contract is signed.

Then tell them, politely and in writing, that under Article 7:417 lid 4 BW you are not obliged to pay mediation fees because they represent the landlord. Most expats are amazed how often the fee just… disappears at that point. Agencies know the law. They're testing whether you do.

If they insist, you have two choices. You can pay under protest (explicitly, in writing: "paid under protest, reserving all rights") to secure the flat, then reclaim. Or you can walk. In Groningen, Delft, Eindhoven — any city with some slack in the student market — walking is realistic. In central Amsterdam in September, less so. That's the honest trade-off.

If you've already paid, you have up to five years to get it back. That's a long runway, so don't panic if you're reading this a year into your tenancy.

What you need: the invoice or bank transfer receipt, a screenshot of the original listing showing the agent advertised it, your rental contract, and any emails with the agency. Woonbond,!WOON and Juridisch Loket publish sample letters (terugvorderingsbrief) — use them. Send the letter by aangetekende post (registered mail) and give the agency two weeks to refund.

About a third of the cases I hear about end there. The agency refunds, sometimes grudgingly, because they don't want the paper trail in court.

If they refuse, the realistic next step is a no-cure-no-pay service like Rentreturn or a lawyer such as Arslan Advocaten who specialises in expat cases. They take a percentage — typically 20–30% — of what they recover, which beats fronting legal fees. The Huurcommissie cannot help here, so don't waste weeks trying to route it through them.

One tip that matters: if you're still living in the property, wait to escalate until you feel secure, especially if you don't have a permanent contract. The law is on your side, but landlord retaliation in a tight market is real.

House Hunter watches over a thousand Dutch rental sites and pushes matching listings to users within seconds. The reason that matters for this topic: when you're first in line on a legitimate listing, you don't need to go through a gatekeeping agent who's padding the deal with illegal fees. You're responding directly to the ad the landlord or their agent posted, which also gives you the evidence you need later if a suspect invoice shows up.

We don't charge bemiddelingskosten. We don't take money from landlords. Our users pay us a subscription for the alerts, and that's the entire business. I mention this only because people ask, and because I want to be clear we're not the entity on the other side of your invoice.

What I'd ask any international moving here to internalise: the Dutch market has real costs — first month's rent, one or two months' deposit (waarborgsom), sometimes a BSN-linked utility setup, maybe furniture takeover (overname). Those are normal. An agency fee to the tenant, when the agent is advertising the place, is not normal. It's an extraction that survives because people don't push back.

Push back.
