Rent Increase: Check Your Rights in Finland

If a landlord notifies you of a rent increase, as a tenant you have the right to check the grounds for the increase and request explanations. This guide walks step by step through how to check the legality of a rent increase in Finland, what documents and evidence to collect, how to communicate with the landlord and when to seek help from authorities or dispute resolution. It also explains when an increase may be considered unreasonable and how a complaint proceeds to the Consumer Disputes Board or district court. The content is written clearly for tenants without legal jargon so you can act quickly to protect your housing rights. The guide includes practical examples, deadlines and template letters to help you appeal or request clarification in writing. We also explain when to pay the original rent pending resolution and how to prove the apartment's condition if the increase is based on improvements. If no agreement is reached, we outline how to file a complaint with the Consumer Authority (KKV) or seek a court decision.

How to check a rent increase

First, check whether the landlord has provided a clear calculation and justification. Rent increases are governed by the Act on Residential Leases (481/1995)^[1], so compare the notice to the statutory rules and request additional information in writing if needed.

• Collect all rent receipts and payment records as well as photos and other evidence (evidence).
• Request a written explanation and calculation from the landlord (form).
• Check the dates and deadlines stated in the notice (days).
• Assess whether the increase is based on improvements or other costs and consider negotiation or escalation (court).

Deadlines and notices

The landlord must notify you of increases in a timely manner and provide clear justification. If you need court forms or guidance for filings, the official justice portal provides templates and instructions^[2].

• Respond or request clarification in writing as soon as you receive the increase notice to preserve your rights.
• Keep all written communication and format your response as a clear document (file).
• Contact advisory services if you do not understand the grounds for the increase or do not receive answers.

Key takeaways

• Save receipts, messages and photos as evidence.
• Act promptly: reply in writing and observe deadlines.
• Seek help from authorities or consumer advice if no agreement is reached.
