Tenant Checklist: Heating Failure in Germany

Dispute Resolution & Rent Reduction 2 min read · published September 07, 2025

Immediate measures

When the heating fails, act in a structured way: report the defect in writing, document temperature and duration and collect evidence for later steps.

What to document

  • Record date, time and duration of the outage
  • Take photos of thermostats, radiators and measuring devices
  • Collect craftsmen's reports, invoices and heating bills
Keep all receipts and photos neatly organized.

Legal basis

Key bases are the German Civil Code (BGB) §§ 535–580a [1], the competence of local courts (Amtsgerichte) for tenancy law [2] and the Heating Costs Ordinance [3]. For guidance and higher-court decisions, refer to judgments of the Federal Court of Justice [4].

Respond in writing and within deadlines, otherwise claims may be endangered.

FAQ

Can I reduce the rent if the heating fails?
Yes, under certain conditions tenants in Germany can reduce the rent if the usability of the apartment is impaired. The scope of the defect, duration and evidence are decisive.
What deadlines do I have to observe?
Inform the landlord immediately in writing and set a reasonable deadline for repair. For acute outages you should look for emergency services or craftsmen immediately; legal action follows only after documentation.
