Heating Replacement & Tenant Rights in Germany

Modernization & Cost Allocation 3 min read · published September 07, 2025

What tenants need to know

As a tenant in Germany, when a heating replacement is planned under the Buildings Energy Act (GEG)[2], you should know the landlord's obligations and the deadlines for notification and execution. The Civil Code (BGB) regulates landlord and tenant duties, especially maintenance and modernization §§535–580a[1]. Pay attention to formal notices, exact dates and written information about expected costs. For listed buildings, additional permits may apply that extend timelines and durations.

  • Observe deadlines: Check announcement and execution times carefully.
  • Check costs: Request estimates and breakdowns of cost allocations.
  • Secure documentation: Take photos and store correspondence as evidence.
  • Request forms and letters: Ask for all notifications in writing.
  • Legal steps: Find out which local court is responsible if a dispute arises.
Detailed documentation increases your chances of success in disputes.

Heating replacement, cost allocation and the heating costs regulation

Modernizations under the GEG can be partly passed on to tenants; rules of the heating costs regulation and modernization allocation apply. Check especially whether the works count as energy-related modernization and how much the landlord may allocate to the rent. If in doubt, ask for detailed calculations and receipts; the heating costs regulation provides important rules[3].

Monument protection: special procedures and deadlines

For listed buildings, additional permits from the monument protection authority are often required. This can change schedules and costs; request copies of all official orders and conditions. If works take longer or cause greater disruption due to monument protection, document the scope and duration of the impairment for possible rent reductions.

Respond to official or notarized letters within deadlines to avoid disadvantages.

How-To

  1. Check deadlines: Read the landlord's announcement and note all stated dates.
  2. Request forms: Ask for written notifications, cost estimates and permits.
  3. Collect evidence: Photograph the construction condition, save emails and handwritten notes.
  4. Review costs: Request a breakdown of the modernization allocation and compare with the heating costs regulation.
  5. Consider legal action: If disputed, contact the competent local court or seek legal advice.
Keep all original receipts and invoices for at least two years.

Frequently Asked Questions

Who pays the modernization costs for a heating replacement?
The landlord pays the investment costs but may under certain conditions pass part of the costs to tenants; precise rules are found in the BGB and the heating costs regulation.[1][3]
How far in advance must the landlord announce works?
There is no single deadline for all measures; however, announcement should be timely so tenants can prepare. For major interventions, early written notification is common.
Can tenants reduce rent because of noise or outage?
Yes, significant impairments may entitle tenants to a rent reduction. Documentation and legal review are important; in disputes the local court decides.[4]

Key steps in case of dispute

If you feel disadvantaged, first send a letter to the landlord with a deadline to clarify and request necessary receipts. If no agreement is reached, you can bring the matter before the competent local court or seek legal assistance. Record all contacts and dates systematically.

In many cases, conflicts can be resolved out of court through good documentation and clear deadlines.
