Check rent increases for tenants in the Netherlands

Rent increases & indexation (annual caps) 3 min read · published September 11, 2025

As a tenant in the Netherlands you want to know whether a announced rent increase is correct and complies with the rules. This article clearly explains the types of increases — annual indexation and individual increases — and how to check whether a proposal falls within legal limits. You will read which deadlines a landlord must respect, what information must be in the written notice, and which steps you can take if you disagree: from direct contact with the landlord to objecting to the Rent Tribunal (Huurcommissie)[2] or going to the cantonal judge. The text uses simple language and practical examples so you can quickly decide what to do and which documents are important.

When is a rent increase valid?

A rent increase is only valid if the landlord complies with the rules in the Civil Code Book 7[1] and with any agreements in the lease. Important points to check are:

  • Is the increase announced in writing and does it state a clear start date.
  • Is it annual indexation or an individual adjustment (for example after improvements or a higher agreed rent).
  • Does the amount comply with maximum limits or the rules agreed in the lease.
Always keep copies of written notices.

How to check the calculation?

Check the calculation: which base rent the landlord used, which index figures were applied and from which date the new rent applies. Ask for a written explanation if something is unclear. If the landlord refers to statutory indexation, you can consult the exact legal text via official sources[1].

  • Compare the proposed rent with your current rent and with previous increases.
  • Request a specification of the calculation from the landlord if it was not provided.
  • Note the date you received the notice and keep proof of receipt.
Respond to written notices within reasonable timeframes to protect your rights.

What can you do if you disagree?

If you believe the increase is unjustified or too high, first contact your landlord and request clarification. If discussion does not help you can file an objection or start a procedure at the Rent Tribunal or the cantonal judge. The Rent Tribunal deals, among other things, with disputes about rent increases and service costs[2].

  • Send a brief, clear written request for explanation to the landlord first.
  • Collect relevant documents: lease, past rent payments and correspondence.
  • If necessary, submit an application or objection to the Rent Tribunal procedures or seek legal advice.
