Multi-utility billing may seem complex, but with ista it becomes a streamlined end-to-end process: fair, transparent, and fully compliant with Dutch regulations. Residents using multiple energy sources receive a single clear overview instead of separate bills for gas, water, electricity, or heat.
Whether you are an owner, manager, or resident, our smart technology and well-designed billing processes provide the clarity, accuracy, and compliance you need. It all starts with certified submeters for heat, cooling, electricity, and water, professionally installed by our specialists. After installation, we handle everything—from data collection and validation to tariff application and precise final billing.
The result: clear bills in accordance with current regulations, reduced administrative burden, fewer disputes and complaints, time and cost savings, and complete transparency for everyone.
Precise multi-utility billing starts with accurate measurement of consumption. Using smart submetering for heat, water, cooling, electricity, and gas, we track individual usage in every home or unit. This data is periodically transmitted to a central system, eliminating manual readings and providing reliable consumption insights.
With this monitoring service, residents can easily access their usage data through a user-friendly web portal and app. This transparency not only helps them track monthly consumption but also identify potential savings. ista ensures fair and efficient billing, enhancing resident satisfaction.
Our comprehensive solution for multi-utility billing is built on advanced measurement and smart integration. We provide high-precision meters for heat, water, and electricity, available in both wired and wireless versions to ensure accurate and reliable consumption monitoring. All our flow meters are MID-certified. Our billing system automatically processes this data to generate precise bills with transparent, itemized costs and rates.
We can also integrate existing gas and electricity meters into the measurement infrastructure using the ista Pulsonic, provided they have a pulse output, an M-Bus or Modbus protocol, or an EAN code. Through our Administrator Portal, heating, water, gas, and electricity costs can be seamlessly managed in one place, significantly reducing your administrative effort.
Good to know: With our Debicasso service, advance payments and all utilities are billed easily and transparently.

After the first consultation, our specialists evaluate your building’s heating, cooling, water, and electricity systems and recommend the best metering solution for accurate and efficient multi-utility billing.
Once the proposal is approved, our advanced submeters and wireless systems can be quickly installed in the homes with minimal disruption.
Automated data collection ensures the secure transfer of consumption information to a central system, making on-site visits unnecessary.
Residents and property managers can access clear consumption data through an online platform.
Billing is carried out precisely according to applicable regulations, ensuring fair cost allocation and a smooth, hassle-free experience for all parties involved.
Multi-utility billing allows you to manage and charge for heating, cooling, gas, electricity, and water through a single invoice. ista uses submeters installed in each home to measure individual consumption. This data is then read remotely, validated, and used to calculate costs and generate bills. The process is accurate, fair, and fully transparent for both residents and property managers.
Submetering is the service of installing individual meters to measure the consumption of specific utilities—such as heating, water, electricity, or gas—per home, shop, or office in your property. Unlike main metering, which measures total usage across all units, submetering allows each resident to pay for exactly what they consume. This not only ensures fair billing but also encourages responsible energy and water use, helping both property owners and residents reduce costs and environmental impact.
ista provides billing services for heating, cooling, electricity, gas, and water. All utilities can be included in the invoice, whether for residential, commercial, or mixed-use properties.
With ista’s multi-utility billing, energy costs are distributed fairly and transparently. Residents receive a clear invoice based on their actual consumption of heating, cooling, gas, water, and/or electricity, ensuring that everyone pays only for what they truly use.
Yes, billing based on individual consumption encourages energy savings. When residents gain insight into their own energy use, they are more likely to manage it consciously. This can result in lower energy costs for themselves and reduce the building’s overall energy consumption. Studies show that individual billing can lead to significant energy savings and a reduction in CO₂ emissions.
Ja, multi-utility facturering kan helpen uw energiekosten te verlagen. Door het verbruik per woning of unit inzichtelijk te maken, worden bewoners zich bewuster van hun energieverbruik. Dit stimuleert energiebesparend gedrag en kan leiden tot lagere totale verwarmingskosten. Onderzoek, zoals de studie “Effecten van consumptiegebaseerde facturering afhankelijk van de energiekwaliteiten van gebouwen in de EU” van de Technische Universiteit Dresden, toont aan dat individuele facturering kan resulteren in significante energiebesparing en een vermindering van CO₂-uitstoot.
Yes, ista’s multi-utility billing fully complies with Dutch regulations. Our metering and billing processes adhere to all relevant national requirements, including the Heat Act, data protection rules, and guidelines for transparent cost allocation. All meters used meet EU certification standards, and our billing procedures ensure accuracy, fairness, and full oversight, so both residents and property managers can rely on correct and transparent billing.
Data is collected via IoT-enabled submeters that transmit consumption information remotely. ista’s billing system processes and validates this data before generating accurate and transparent bills. This eliminates the need for manual meter readings and reduces the risk of billing errors.
Yes, ista’s energy metering solutions are compatible with a range of renewable energy sources, such as solar thermal systems and heat pumps. This ensures that buildings using sustainable energy solutions can still benefit from accurate measurements and fair billing.
