Who Pays for Insulation & Windows for Tenants in Denmark
This guide helps tenants in Denmark understand who normally pays for insulation and window replacement. Many disputes arise because responsibility can depend on the lease agreement, the age of the property and whether the change is necessary to maintain basic habitability. Here we explain the difference between routine maintenance and major improvements, what obligations landlords have under the Rent Act[1], and how you as a tenant can document problems, request repairs or complain to the Rent Tribunal[3]. The text also gives concrete steps to collect evidence, contact the landlord and find official guidance on Borger.dk[2].
Responsibility for insulation and windows
As a general rule, the landlord is responsible for ensuring the dwelling is habitable and meets standards for warmth and airtightness. This often means that major works such as replacing leaky windows or insulating at the landlord's initiative are paid by the landlord. If the tenancy suffers from significant defects, the tenant can demand repairs or rent reduction under the Rent Act[1].
However, the contract may allocate minor maintenance tasks to the tenant, e.g. small sealings or routine window cleaning. If the tenant wants to improve the property (e.g. install additional insulation or new windows), it normally requires the landlord's permission and payment responsibility should be agreed in advance.
- Replacement of windows due to normal wear is typically paid by the landlord because it affects the dwelling's standard.
- Minor repairs and ongoing maintenance may fall to the tenant if specified in the lease agreement.
- Major energy renovations often require notice or a special agreement and can have specific rules about rent increases.
Practical steps when facing insulation or window issues
When you discover a problem, it is important to act systematically: contact the landlord in writing, set a reasonable deadline for repair, and keep all communications. If the landlord does not respond or refuses responsibility, you can bring the case before the Rent Tribunal or consider legal advice. Use official guidance to ensure you follow correct procedures.[2]
