Sub metering — meaning, why it matters, and how PG/co-living use it
Sub-metering turns one building bill into room-wise usage so billing becomes fair and wastage becomes visible. In PG/co-living it is usually paired with prepaid recharges for 100% collection and fewer disputes.
What is sub-metering?
Sub-metering adds meters downstream of the main utility meter so you can measure each tenant/room/floor separately. It’s common in PGs, co-living, malls, factories and multi-tenant offices.
Why sub-metering improves both fairness and savings
- —Tenants pay for what they use (no cross-subsidy).
- —Usage transparency reduces waste automatically.
- —Common-area costs can be split with clear rules.
- —Operationally easier than manual meter reading with smart IoT meters.
Sub-metering + prepaid (Encharge model)
In PGs and co-living, sub-metering is paired with prepaid recharge: tenants pay upfront, the meter deducts usage, and owners get automated settlement and auditability.
