Tenant's Guide: Energy & Heating in Finland

Energy, heating & indoor climate 2 min read · published September 11, 2025

Many tenants worry about energy costs, heating failures or poor indoor air because they affect daily life, finances and health. In Finland tenants have rights and obligations, and it is wise to handle complaints methodically: document the problem, notify the landlord in writing and monitor repair progress. This guide explains how to draft a complaint, what attachments to collect and which authorities to contact if needed. The content is based on housing legislation and official guidance.[1] The guide covers both urgent heating issues and long-term indoor air problems, and advises when to demand repairs or seek outside assistance.

What to do first?

Start by mapping the problem's nature and scope. Determine whether the issue affects living conditions or health, and try to identify when the problem began. Also collect measurement results or temperature observations if possible.

  • Record the problem type, dates and the impact on living conditions.
  • Take photos or keep a log of measurements.
  • Notify the landlord immediately by phone and confirm the notice in writing.
  • Keep all messages, receipts and repair bills as evidence.
Keep all messages and receipts organized and stored safely.

Written complaint

Prepare a clear written complaint describing the problem, its effects and requesting repairs within a reasonable time. Attach photos, measurements and a copy of the lease.

  • Describe the defect clearly: where, when and how it appears.
  • Attach evidence such as photos and measurement results.
  • State the requested remedy and propose a reasonable deadline.
Send the complaint in writing and keep proof of sending.

If the landlord does not respond

If the landlord does not answer or refuses to remedy the situation, contact advisory services or seek a solution via authorities. The Consumer and Competition Authority (KKV) provides guidance on consumer disputes, and if needed the matter can be taken to district court or handled through other legal remedies.[2] In some cases the issue may be resolved through court proceedings or enforcement authorities.

Detailed documentation increases your chances of success in disputes.

FAQ

The landlord must remedy defects within a reasonable time depending on severity; urgent matters like lack of heating in winter require prompt action.

Withholding rent may be possible only if the landlord has neglected repairs and the condition substantially impairs living; always start with a written complaint and seek legal advice if needed.[1]
Who do I contact if the landlord won’t help?
Contact the Consumer and Competition Authority (KKV) guidance and local legal services or consumer advisory services, and prepare the case for possible court action.[2]
