The safe way to your utility bill statement
Utility bill assistant for private landlords
The utility bill assistant reads your building or house cost statement, checks every line item for allocability under Section 2 BetrKV, distributes the costs correctly across your tenancies and produces a complete statement document — no preparation, no account, right in your browser. Nothing needs to be set up beforehand: the statement your property manager sent you is enough.
See it first, then start: the utility bill calculator
The calculator is not a promo video, it is the real tool: drop your building cost statement or individual invoices into it and see in under a minute what CIRO reads from them, amounts, cost types, allocation keys and whether your tenant shares each item. Every share is recalculated instead of simply copied, and deviations are flagged. Your files are only read, never stored, and you don't need an account.
From the analysis straight into the assistant
Whatever CIRO has read from your document, you never type twice: address, billing period and cost line items carry over into the assistant automatically. It walks you step by step through property, tenancy and distribution, under the German operating and heating cost ordinances, including pro-rata periods for tenant changes. The result is a complete statement document per tenancy, delivered as a PDF, by email if you like.
No special property management? No problem.
You rent out your condominium but have no special property management (Sondereigentumsverwaltung, SEV)? Then all you get from the homeowners’ association is the annual statement – and the utility bill statement for your tenant is on you. That is exactly where the utility bill assistant comes in: it reads the association’s statement, separates recoverable from non-recoverable items under Section 2 BetrKV, re-checks every share and turns it into the finished tenant document. No SEV contract, no subscription – 20 € per statement, paid only when the document is created.
Your path to the finished statement
From a building cost statement with 20 line items to a ready-to-send PDF, in one pass.
Typing and guessing
Manual
The building cost statement sits on your desk: 20 line items, a stack of invoices, and for every line the question whether your tenant has to share it. You type amounts into a spreadsheet, work out shares by hand and hope the total adds up.

„We developed every check in the utility bill assistant together: which item is recoverable under Section 2 BetrKV, which deadline applies and what really belongs in the utility bill. Our principle: Excel adds up whatever you type in – it won't tell you whether an item is recoverable or the deadline still open. The assistant checks exactly that, and names the rule behind it.“

Frequently asked questions
No. The calculator and the assistant run entirely in your browser, without registration. You drop in your documents, build the statement and receive the finished document by email. You only create a CIRO account once you want to manage your properties permanently or repeat the statement next year with one click – then you simply carry everything over into your account.
Yes – that is exactly what the utility bill assistant is built for. A special property management (SEV) handles the tenant statement for rented condominiums, for ongoing fees. With the utility bill assistant you do this step yourself: drop your homeowners’ association statement into the calculator, CIRO separates recoverable from non-recoverable items under Section 2 BetrKV, re-checks every share and creates the finished tenant document – a one-off 20 € per statement, with no SEV contract and no subscription.
The calculator reads your documents once and shows you the result – the files are not kept after the analysis. Only when you then start the assistant is the data created that your statement needs – GDPR-compliant on European servers. If you don’t carry it into a CIRO account, everything is deleted automatically after 30 days; your access link to the finished document is valid for the same period.
Trying it out, letting the AI read your documents and building the statement is free. You only pay at the very end, when you have the finished statement document created for your tenants – a one-off 20 € per statement, no subscription and no account. If you manage several properties or settle every year, the statement is included in your CIRO plan – and everything you created here moves with you when you switch.
The distribution follows the German operating cost ordinance (BetrKV) and heating cost ordinance, including pro-rata periods for tenant changes, and the document contains the mandatory details under Section 556 BGB. In addition, the CIRO statement assistant reviews your statement for anomalies and gives you guidance – based on a rule set developed and reviewed together with tenancy-law attorneys – the final responsibility and the last word stay with you; the guidance is not legal advice. These checks are developed together with Denise Sonnenschein, an attorney for German tenancy law with her own firm.
