Who Pays When Tenant Appeals a Rent Increase in Norway

Rent & indexation (CPI/index, caps) 3 min read · published September 11, 2025

As a tenant in Norway you can complain if you believe a rent increase is unreasonable or lacks legal basis. This guide explains who must pay if your complaint is upheld, which steps you should follow, and which deadlines and documents are important in a rent increase case. We describe how the Tenancy Disputes Board (HTU) and the courts handle disputes, what happens to rent charged in excess, and when a landlord can claim compensation. The goal is to give clear, practical advice to help you as a tenant secure your rights without legal jargon. Read on for concrete steps, sample letters and what to expect from HTU and the courts.

What happens if the complaint is upheld?

When HTU or the courts assess the case and conclude that the rent increase was invalid, the tenant may be refunded rent that was charged without legal basis or that is unreasonable. This follows from the Tenancy Act.[1] The decision can determine whether the landlord must reimburse, whether previous payments can be credited against future rent, or whether other corrections should be made.

In most cases the landlord must refund overpayments to the tenant.

Who pays back?

If the complaint is upheld, the landlord is normally ordered to reimburse what the tenant has paid in excess. If the tenant has been charged incorrectly for several months, the amount can be significant. In some cases the parties can agree on a different settlement, but without agreement the landlord remains responsible for unlawful collection.

Payment records strengthen your complaint.

Documents you should collect

  • The lease or agreement showing the agreed rent.
  • Receipts and bank statements showing paid rent.
  • Emails and SMS that document communication about the price change.
  • Written notice of rent increase from the landlord.
  • Photos or other evidence supporting technical or factual claims.

Deadlines and practical requirements

It is important to act quickly. Complaints should normally be submitted in writing and within a reasonable time after you became aware of the increase. Many cases begin at the Tenancy Disputes Board (HTU), but some may end up in the courts if the parties do not agree.[2]

Respond to demands and deadlines in writing and document all communication to protect your rights.

When can the landlord demand repayment from the tenant?

If the landlord later finds that they gave a discount or set an incorrect price, there may in some situations be grounds for a counterclaim. However, the landlord cannot demand repayment for amounts the court or HTU has found unreasonable or invalid without special grounds. If the case involves fraud or incorrect information from the tenant, other rules may apply, and this is assessed individually.[3]

Always clarify which amounts are claimed and why to avoid misunderstandings.
