How Tenants Can Challenge Rent Increases in Denmark

Rent, regulation & indexation 2 min read · published September 11, 2025

How can a tenant challenge a rent increase?

As a tenant you can often respond if you believe a rent increase is unreasonable or lacks legal basis in the Rent Act[1]. Before acting, review the lease, the specific increase and any notices you received from the landlord. A constructive dialogue can resolve misunderstandings, but you also have the option to have the matter reviewed by the rent tribunal or ultimately by the courts if dialogue fails.

Keep all written correspondence and receipts organized in one folder.

What documentation should you gather?

  • Documents (document): copy of the lease, invoices and past receipts.
  • Photos and evidence (evidence): images of condition, maintenance issues, or improvements.
  • Deadlines (deadline): note dates for notifications and response deadlines from the landlord.
  • Objection/complaint (file): send a written objection to the landlord and consider filing with the rent tribunal.
Early documentation increases the chance of a positive outcome in a complaint.

Common reasons to challenge an increase

A rent increase can be contested if it exceeds market rent, lacks justification, or if claimed improvements do not meet legal requirements. If the landlord cites improvements, there must be documentation of costs and relevance.

Deadlines and procedure

There are often fixed deadlines to raise an objection. If you want to challenge a rent increase you normally must act quickly and submit a written objection to the landlord. If the case proceeds, the rent tribunal can rule, and there is a possibility to bring the case before the courts later.[2]

Make sure to meet all deadlines to preserve your right to complain.
