Smart Meter: Documenting Costs for Tenants in Germany

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

Many tenants in Germany face questions during the Smart Meter rollout: who pays costs, which documents are needed, and how to prove claims in disputes? This text clearly explains how you as a tenant in an older building can document costs, installation or meter point changes, and any retrospective charges. You will learn which documents are useful, how long to keep receipts, and when formal papers are required. The aim is to secure your rights, avoid later disputes, and — if necessary — provide court-proof evidence. The guidance is practical and points to relevant laws, authorities and typical forms.

What tenants in older buildings should watch

During the rollout there may be installation costs, conversion work in the house connection room or the allocation of ongoing metering costs. Request written information from the landlord and save every receipt: invoices, emails, photos before and after installation and the installation report from the metering point operator. Check the service charge bill under the Operating Costs Ordinance (BetrKV) and review claims under maintenance and rent reduction rules in the German Civil Code (BGB) §§ 535–580a[1].

Detailed documentation increases your chances of enforcing legitimate claims.

Specific documents and retention periods

  • Invoices from the metering point operator or contractor invoices with date and service description.
  • Email correspondence or written announcements from the landlord about the measure.
  • Photos of the metering point before and after installation, ideally with a timestamp.
  • Protocols or handover reports of the installation, if available.
Keep all receipts for at least three years, preferably five years.

Rights, duties and relevant laws

The landlord must generally announce modernizations and changes and cannot arbitrarily pass on costs to tenants; review rules such as the Heating Cost Ordinance and the Operating Costs Ordinance. If uncertain about the permissibility of cost allocation or the scope of modernization, court interpretations may be relevant. Information on the Smart Meter rollout and metering point operators can be found at the Federal Network Agency[2].

Local courts (Amtsgerichte) are usually responsible for rental law disputes.

Practical steps for unclear charges

  1. Request full receipts and a breakdown of costs from the landlord in writing.
  2. Document deadlines and, if necessary, set a deadline for submitting missing documents.
  3. If the landlord does not respond: file an objection and consider reducing rent only after legal review.
  4. In continued dispute, compile evidence and contact the Amtsgericht for guidance.
Respond to legal letters within deadlines to avoid losing rights.

Forms and official templates

For legal proceedings and formal applications use the official templates from justice portals. Statutes and ordinances are available at Gesetze im Internet, including the Heating Costs Ordinance (HeizKV)[3]. If a procedure becomes necessary, consult the Federal Court of Justice for relevant decisions or contact the local district court for information on complaint forms and jurisdiction[4].
