Rent, regulation & indexation 3 min read · published September 11, 2025

As a tenant in Denmark, a sudden heat outage can cause discomfort and uncertainty. This guide explains your rights and practical steps: how to document missing heating, what demands you can make of the landlord, how rent can be adjusted or reduced, and when you should contact the rent tribunal or the courts. We review the complaint process, typical deadlines and which pieces of evidence support your case so you can act quickly and correctly. You also get concrete advice on temporary solutions, communicating with the landlord and how a reduced rent is calculated. If heating is necessary for health or safety, your options for rapid action are explained.

What can you do as a tenant?

  • Contact the landlord immediately, explain the problem and ask for expected duration and remedy.
  • Document time, duration and temperatures with photos, video or a logbook.
  • Seek temporary solutions such as electric heating if it is safe and permitted in your dwelling.
  • Always send a written reminder or claim to the landlord so there is evidence of your contact.
Keep all messages with the landlord together in one folder or email thread.

How do you document a heat outage?

Good documentation makes it easier to obtain rent reduction or compensation. Note the date and time for each period without heat, take photos of thermometers or radiators, and keep SMS or emails with the landlord. Consider having a neighbor or third party confirm the conditions if possible.

Photos and a simple temperature log can make a decisive difference in a complaint case.

Rent reduction and compensation

As a tenant you may be entitled to reduced rent if the heating does not meet what was agreed or is necessary for habitation. Start by requesting remedy from the landlord and document the defect in writing. If the landlord does not respond, you can calculate a reasonable rent reduction amount and demand repayment for the period the defect existed. Seek advice from the rent tribunal or consult the relevant provisions in the Rent Act to assess your situation [1].

Respond in writing to the landlord's messages and keep copies of everything.

Deadlines and complaint options

If you cannot reach an agreement, you can bring the case before the local rent tribunal or the district court. The rent tribunal handles many disputes about rent reduction and can often be faster and cheaper than the courts [2]. Remember to meet any complaint deadlines and submit all evidence with your complaint.
