Allocation Key for Back Charges: Tenants Germany

As a tenant in Germany, supplementary charges for operating costs can arrive unexpectedly. The allocation key is decisive: it determines by which distribution key landlords allocate costs such as heating, water or janitorial services to the households. This text explains in plain language when you as a tenant may check the allocation key, how to contest additional claims and which forms and deadlines are important. I describe practical steps for documentation, communication with property management and taking matters to the local court if necessary. The goal is to give you clear action recommendations so you can understand operating cost statements and effectively limit justified additional claims.

What is the allocation key?

The allocation key determines how individual cost items on the operating cost statement are distributed. It can be specified in the rental agreement or arise from the nature of the costs; certain types of costs and the obligation to account for them are regulated by the Operating Costs Ordinance.^[2] At the same time, landlord duties under the Civil Code oblige proper accounting and disclosure of records.^[1]

When can landlords demand back charges?

A supplementary claim is generally permissible if a proper accounting for the accounting period is presented, the claimed items are explainable and the accounting is made within the statutory deadline. If transparency or formal basis is missing, tenants can object.

• Observe deadlines: Landlords must usually issue the accounting within one year after the end of the accounting period.
• Cost transparency: Each cost item must be clearly documented and calculated.
• Contractual distribution key: If a written allocation key exists in the rental contract, it is authoritative.

How can tenants check additional claims?

Proceed systematically: demand the complete operating cost statement with supporting documents, check the accounting period and recalculate the items with the stated allocation key. Documentation helps: copies, photos of meter readings or reading protocols can be important.

• Request and sort documents: Ask for invoices and accounting records.
• Check consumption and reading data: Do meter readings and reading logs match your records?
• Recalculate: Verify distribution and totals with the stated allocation key.

Forms and templates

Important official measures and forms include, for example, the payment order in the court dunning procedure and the complaint form for civil claims at the competent local court. A payment order can help when the landlord asserts a clear claim; tenants themselves rarely use it — it is usually filed by the creditor (landlord). You use the complaint form when you need to enforce a payment or seek a judicial determination of the invalidity of a supplementary claim. Sample texts for objections can be written as a registered letter and sent to property management. Official procedural information and forms can be found at the justice authorities of the federal states or on central portals like justiz.de.

Options in disputes: local court & deadlines

If differences cannot be resolved amicably, the local court (Amtsgericht) is competent; court proceedings follow the rules of the Code of Civil Procedure.^[4] In court files, deadlines, evidence and a clear presentation of the facts are crucial. The Federal Court of Justice may decide on legal questions and precedents in higher instances.^[5]

Frequently Asked Questions

No. You can demand access to the documents, review them and object within the accounting deadline; unjustified or unsupported items should be disputed in writing.

Typically, the one-year deadline after the end of the accounting period applies; exceptions may arise from the contract or special circumstances.

Write a formal objection, request documents and consider advice or filing a complaint at the local court if the landlord does not respond.
