CO₂ cost allocation 2023+
Split CO₂ costs
right at last.

- Calculates the tier (1-10) from energy consumption and living area
- Correct landlord/tenant split by tier (0/100 to 95/5)
- Documentable for 10 years per § 9 CO₂ cost allocation
- Works with gas, oil, district heating, heat pump, pellets

Testimonials
How Rentprime helps day to day.
Illustrative use cases — what working with Rentprime looks like.
„Anyone who used to prepare the service charge statement every year with an Excel template over several weekends now gets it done with Rentprime in a single afternoon — and the CO₂ topic runs automatically alongside."
Example: private landlord, 6 units
„If there's a dispute over an old statement, the tenant can review everything transparently in the portal — which removes the basis for many conflicts from the outset."
Example: community of heirs, 3 buildings
„Utility bills are simply dropped in, checked briefly, done — the AI receipt recognition saves the hours of work it used to take."
Example: property management, 42 units

Definition

What is a service-charge statement?
The annual breakdown of allocable operating costs — governed by German Civil Code and German operating-costs regulation. You have 12 months after the end of the billing period; miss it and back-claims are lost.

Topics: German Civil Code · German operating-costs regulation · Operating Costs Ordinance · billing period

CO₂ cost allocation — landlord share
The landlord pays 0% to 95% of the CO₂ cost, depending on the building’s energy efficiency. 10 tiers by kg CO₂ per m² per year. For unrenovated older buildings this can get really expensive.
Topics: CO₂ cost allocation · tier model · landlord share · energy efficiency
Heating costs: 70% consumption / 30% area
Mandatory split under the Heating Costs Ordinance — at least 50% by consumption, at most 70%. Since 2022: monthly consumption info to tenants (German heating regulation). Breaches allow a 15% reduction.
Topics: German heating regulation · Heating Costs Ordinance · 70/30 split · consumption info
Photo in, data out
AI detects supplier, amount, period, cost type and property assignment in under 3 seconds. Works with all major German utilities. Saves about 4 minutes of manual entry per receipt.
Topics: AI receipt recognition · OCR · British Gas · ista · Techem · municipal utilities
Excel vs Rentprime
In Excel: 4–12 hours per property a year for the service-charge statement. With Rentprime: 30 minutes the first time, 10 minutes in following years. Collect receipts, Rentprime does the maths.
Topics: Service-charge software · Excel alternative · time saved
Modern property management software like Rentprime takes the recurring tasks off your hands: receipts are automatically read by receipt AI, distribution keys applied per cost type, statutory deadlines tracked. On average you save 6-12 hours per property per year — with multiple properties quickly several weekends. The investment in software pays off after a few months.
