📈 My rent increase seems too high — can I object, and to whom?

Direct answer

Rent increases are regulated almost everywhere: a maximum percentage per year, a reference index, or a rent cap in tense areas, plus a written notice with a minimum lead time. Do not just pay it. Object in writing to the landlord citing the rule, then ask Vrederechter — verzoeningsprocedure (rechtbanken-tribunaux.be) to check or decide — the tenancy body for Belgium does this for free or a small fee. Huurdersbond (huurdersbond.be) tells you the current cap and helps you write. If the landlord threatens termination for refusing, Bureau voor Juridische Bijstand (pro Deo) / Justitiehuis (advocaat.be) advises on your protection.

🗣️ What to say

"I received your notice of [date] increasing the rent from [amount] to [amount] from [date]. This exceeds the permitted increase of [rule]. I do not accept it. I will continue to pay [current / permitted amount] and refer the notice to Vrederechter — verzoeningsprocedure for review."

🪜 Step by step

  1. Check the noticeWritten, with the new amount, the date, the basis. Missing any of these usually makes it invalid.
  2. Check the capIndex, percentage or local rent cap — Huurdersbond publishes the current figure. Many increases are simply above it.
  3. Object in writingCite the rule. Keep paying the old (or permitted) rent — never nothing.
  4. Ask Vrederechter — verzoeningsprocedure to decideFree or cheap; the decision fixes the lawful rent and binds the landlord.
  5. Threats? Bureau voor Juridische Bijstand (pro Deo) / JustitiehuisRefusing an unlawful increase is never a ground for eviction.

❓ Frequently asked

Can the rent go up every year?

Usually at most once a year and within the cap. Some countries freeze rents for the first year of a contract.

I signed a contract with an indexation clause

Indexation is allowed but limited to the official index and often to a maximum; the clause cannot exceed the law.

What if I already paid the higher rent?

You can reclaim the excess for the past months, in most countries up to several years back, through Vrederechter — verzoeningsprocedure.
