Tenants Negotiate Heating Replacement in Germany

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

Rights and Duties for Heating Replacement

As a tenant you should know which duties your landlord has when replacing a heating system and which rights you have. The basic regulations on duties and maintenance are found in the Civil Code, especially in §§ 535–580a.[1] When modernizations are planned, the law requires appropriate notice and a cost breakdown; at the same time tenants are protected from disproportionate allocations.

Tenants are entitled to a habitable apartment even during modernization works.

What Tenants Should Watch

  • Advance notice and access: The landlord must communicate dates and scope in good time.
  • Cost breakdown: Ask for a detailed calculation showing which items are modernization-related.
  • Observe deadlines: Termination, objection and execution deadlines must be followed; check them carefully.
  • Disruptions and repairs: Document impairments and agree on clear restoration deadlines.
  • Check rent reduction: In case of significant impairment a rent reduction may be possible; document extent and duration.
Keep all correspondence, photos and invoices related to the works organized.

How to Negotiate in Practice

Proceed factually: request a written cost estimate, ask about alternatives (e.g. phased implementation) and propose a timetable that considers family needs. In disputes, evidence, witnesses and possibly legal advice help.

  • Collect evidence: photos, logs, noise records and correspondence.
  • Negotiate in writing: Draft concrete offers and deadlines to the landlord.
  • Propose family-friendly dates: Request coordination of workdays and quiet hours.
  • Clarify cost sharing: Ask about subsidies or calculated energy savings.
  • Court steps only as last option: Tenancy disputes are usually heard at the local court.[4]
A polite, well-documented request increases your chances of a fair compromise.

Forms and Official Authorities

There is no single "heating replacement form," but for court proceedings or subsidy applications tenants use standardized forms such as the application for legal aid (PKH) or applications for housing allowance or the housing entitlement certificate at local authorities. For technical rules the Building Energy Act (GEG) is authoritative.[2] For heating cost billing the Heating Costs Ordinance applies.[3]

Respond to deadlines set by your landlord promptly to avoid losing rights.

Frequently Asked Questions

Who pays for the heating replacement?
Generally the landlord bears the investment costs; for modernizations partial allocations may be possible; examine the cost breakdown carefully.
Can the landlord modernize at will?
Modernizations are possible but must be announced and justified; the GEG and other regulations may set technical requirements.[2]
Can tenants reduce the rent?
In case of significant disruption such as lack of heating or severe noise, a rent reduction may be possible; document extent and duration.
Where to turn in case of dispute?
Many tenancy disputes are heard at the competent local court; an out-of-court settlement is often advisable first.[4]

How-To

  2. Write a formal letter with demands and a deadline to the landlord.
  3. Seek a clarifying conversation and record results in writing.
