Submetering reveals who used what behind the building’s main meter. A fair charge still requires reliable readings, a documented allocation rule and a calculation the tenant can inspect.
A main or fiscal meter records the building’s supply. Submeters measure tenants, floors, systems or zones downstream so the total can be understood and allocated with more evidence than an estimate.
Submeters do not replace the supplier’s meter or change the building’s total bill. They divide the internal picture. The difference between the main meter and all mapped downstream meters becomes its own signal: common use, technical loss, timing mismatch, unmetered circuits or a fault that needs investigation.
Electricity, water, gas and thermal energy can all be submetered where suitable devices, installation and local rules allow it. The useful boundary is usually the tenant, unit, floor or major shared system.
Charge direct consumption to the responsible meter, then allocate the genuinely shared pool by the lease basis agreed before billing: area, equal share, user group or a documented mixed rule.
Vacancy, caps, discounts and landlord responsibilities must remain visible. A tenant’s percentage should not change silently because another unit became empty or received a commercial concession.
Learn how common-area costs are split
Consider a hypothetical three-tenant office with one main meter, three tenant meters and three common-system meters. The figures illustrate the calculation, not a client result.
A defensible period collects and validates readings, applies tariff and allocation rules, resolves exceptions, receives approval and then locks. Later corrections keep their own reason and trail.
A meter that can send data is not automatically approved for fiscal or tenant billing. Meter class, verification, VAT, recharge and energy-resale rules depend on the jurisdiction, contract and use case.
Billing suitability depends on the metrology rules that apply where the building is, and recharge and invoice treatment depend on the lease and local tax law. This guide is operational education, not legal or tax advice.
Volts connects supported meter data with tariff, occupancy and allocation records, then carries the approved result into billing and balances.

It depends on jurisdiction and use. Operational monitoring may accept devices that are not valid for fiscal or tenant billing. Confirm the metrology and contractual requirements that apply before billing from it.
Not if they expose a supported reliable output and remain fit for the intended use. Survey each model, interface, installation and verification status before deciding.
Their direct consumption and common-area responsibility follow the lease and local rules. Keep the amount separate instead of silently increasing occupied tenants’ shares.
Heat meters measure delivered thermal energy; heat-cost allocators estimate a share under a regulated method. Devices and rules vary by market, especially in residential buildings.
Close responsibility on the approved handover dates, using the applicable readings and prorated shared rules. Mark any missing-data treatment explicitly.
Check reading times, transformer or conversion factors, unmapped circuits, meter tolerance, communications gaps and physical loss. Do not allocate an unexplained difference automatically.
A tenant sees the relevant meter, period and calculation, and never another tenant’s data.
No. It improves evidence for direct use. Fairness still depends on reliable data, a lawful and documented allocation basis, consistent vacancy treatment and a calculation the tenant can reproduce.
Bring one recent utility period, the meter list and your current allocation rule. We will map the evidence chain, expose the gaps and show how Volts would close it.
