Tenant Responsibilities: Insulation and Windows in Sweden

Maintenance & repair duties 2 min read · published September 11, 2025

As a tenant it can be hard to know who should pay for improved insulation or a window replacement. In Sweden there are rules that govern when the landlord must remedy deficiencies in heating, drafts or condensation and when the tenant is expected to handle minor maintenance. This guide explains the differences, shows which evidence is important and gives practical steps to resolve disputes without unnecessary costs. The text is aimed at tenants in rental apartments and describes when you should contact the landlord, document damage and when a formal review may be relevant.[1]

What applies to insulation and windows?

The main rule is that the landlord is responsible for the apartment's basic standard and that the dwelling maintains normal living standards. Minor measures and spot treatments can sometimes be the tenant's responsibility if the parties have agreed so in the lease or if the damage was caused by the tenant. If windows or insulation affect heating, moisture damage or fire safety, this is often the landlord's responsibility to fix.

Keep receipts and document faults with dates and photographs.

Who pays? Examples and practical guidance

  • The landlord pays for major repairs and replacements of windows or extensive insulation work that affect the apartment's standard.
  • The tenant may need to cover minor sealing or ongoing maintenance if it is stated in the lease or the damage was caused by the tenant.
  • If you cannot agree, you can apply for a review at the Rent Tribunal for a binding decision.[2]

Before major interventions: request a written plan from the landlord with cost responsibility and schedule. If the landlord remedies problems like poor insulation it can affect the rent level after renovation; discuss terms in writing in advance.

Documentation and clear communication reduce the risk of misunderstandings.

What to do in case of moisture damage or drafts

For moisture damage or cold draughts: report the damage in writing to the landlord and request a written response. Take photographs, save dates and any cost estimates. If measures are not taken within a reasonable time you can take steps to demand action or compensation.

Frequently asked questions

Who pays when windows leak in during rain?
Usually the landlord, since leaks affect the living standard. Report the damage in writing and save evidence.
Can I replace a window myself for better insulation?
You should first get written approval from the landlord. An unauthorized window replacement may lead to requirements to restore or financial responsibility.
What does an application to the Rent Tribunal cost?
Application fees vary; check current information with the Courts Administration or the Rent Tribunal before applying.[2]

How to

  1. Document the problem with date, description and photographs.
  2. Notify the landlord in writing and request a written plan for measures.
  3. Contact the Rent Tribunal if you cannot reach an agreement for guidance or formal review.[2]
  4. If payment or enforcement fails, the Enforcement Authority may become relevant for legal measures.[3]

Key advice

  • Always record messages and agreements in writing to avoid misunderstandings.
  • Collect receipts and evidence if you claim compensation or rent reduction.
