Contest Smart Meters: Tenants in Germany

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

Many tenants in social housing wonder whether they can contest the installation or billing of smart meters. In Germany, tenancy law protects tenants from unreasonable modernizations and cost allocation; at the same time, special laws and regulations govern metering operation and heating cost accounting. This text explains in clear language what rights tenants have, how social housing status affects the process, and which evidence, deadlines and authorities are relevant. I list practical steps — from talking to the landlord to a formal objection letter and, if necessary, a lawsuit at the local court — and point to official forms and courts. The aim is to give you, as a tenant in Germany, a safe, practical action plan.

What tenants need to know

In principle: a modernization or new technology in the building can be permissible, but must not lead to impermissible cost shifting or unreasonable impairment. Rights and obligations of landlord and tenant are regulated in the BGB[1]. Specific rules for metering operation, data protection and billing are found in relevant laws and regulations such as the Metering Point Operation Act (MsbG).[2]

Document every correspondence with the landlord and all meter readings in writing.

In the social housing sector, special regulations on cost allocation or approval of modernizations may apply; check your lease and ask the housing authority whether there are specifics. If the measure qualifies as a modernization under tenancy law, the landlord typically must announce and justify it; otherwise tenants can object or consider a rent reduction.

Respond to landlord letters within deadlines to avoid losing rights.

Practical steps before legal action

Before suing: try to talk, ask about cost sharing, technical details and data protection. Request written information on necessity and cost distribution. Collect evidence such as photos, correspondence and meter readings where possible.

If talks fail, send a formal objection or cease-and-desist request by letter or registered mail. If you later go to court, structured documentation is crucial. A lawsuit is usually filed at the competent local court (Amtsgericht); the Amtsgericht is the first instance for most tenancy disputes.

Forms and official documents

Important official documents you should know:

  • Objection letter (no nationwide template required, but include formal details: date, address, clear reasoning, request for response).
  • Lawsuit form / statement of claim for tenancy disputes: filed at the competent local court; check local jurisdiction and attach evidence.
  • Application for interim relief: only in urgent cases when immediate court intervention is necessary (e.g., to prevent immediate removal).

Frequently Asked Questions

Can the landlord install a smart meter without consent?
Not automatically: if the installation is a modernization or contractual change, announcements and possibly your consent are required; check your lease and the announcement.
Who pays for smart meters in social housing?
That depends on the justification and the lease. The landlord cannot indiscriminately pass on costs that are not permitted; public funding programs may entail special rules.
Can I refuse a smart meter for data protection reasons?
Data protection concerns are relevant; request technical and data protection information from the landlord and possibly a data protection impact assessment.

How-To

  1. Collect: photograph meter readings, note dates and store all correspondence.
  2. Communicate: request written details on installation, cost breakdown and purpose of the measure.
  3. Object: send a formal objection letter with a deadline and justification.
  4. Check: have tenant advice centers review whether a rent reduction or lawsuit has a chance of success.
  5. Legal action: file a claim at the local court if out-of-court steps fail.
