Tenant & Sub-Meter Electricity Bill Splitter 2026 – Fair Discom Bill Sharing
Electricity billing in rented houses, PG accommodations, and multi-tenant commercial properties is one of the most frequent sources of tenant-landlord friction in Indian cities. Landlords often demand arbitrary flat rates of ₹10 to ₹14 per unit, pocketing margins on government subsidies and lower tariff tiers. Under Section 12 of The Electricity Act, 2003, landlords are registered domestic consumers rather than licensed distribution franchisees; reselling power for commercial profit without a distribution license is legally prohibited. To maintain transparency, state electricity ombudsmen and consumer forums recommend the Proportional Blended Rate Method. This approach divides the official DISCOM monthly invoice by total units consumed on the primary meter, ensuring fixed demand charges, duty, and subsidized lower slabs are shared equitably across all private sub-meters according to exact consumption.

Tenant & Sub-Meter Billing Science: The Proportional Fair Sharing Law
In multi-tenant rented homes and commercial apartments across India, electricity billing frequently leads to severe disputes. Landlords often arbitrarily demand flat charges of ₹10 to ₹14 per unit without accounting for government lifeline subsidies, slab tiers, or common area meters. Under the Electricity Act 2003 (Section 12), landlords are consumer-distributors, not licensed electricity resellers, and cannot legally earn commercial profit on domestic utility power. This guide establishes two legally defensible, mathematically exact billing frameworks.
Averages high slab tariffs and low lifeline subsidies proportionally among everyone based on their actual consumption.
Units are measured from sub-meter: Current Reading minus Previous Reading, multiplied by the building's blended rate.
Accounts for water pump motors, staircase and corridor lights, parking sensors, or owner's personal floor consumption.
Comparison: Proportional Fair Sharing vs Arbitrary Flat Rate Exploitation
| Billing Method | How It Works | Tenant Consuming 120u | Landlord Fairness | Legal Standing |
|---|---|---|---|---|
| Proportional Fair Share (Recommended) | Total DISCOM Bill ÷ Total Main Units gives blended rate applied to sub-meters | ₹600.00 (@ ₹5.00/u) | 100% of bill recovered without deficit | 100% Legal |
| Agreed Flat Rate + Fixed Share | Written agreement rate (e.g. ₹7.50/u) + equal division of fixed meter rent | ₹950.00 (120×7.5 + ₹50 fixed) | Predictable rate, protects from slab surges | Contractual |
| Arbitrary Flat ₹12/u Mark-up | Landlord imposes inflated rate to profit off residential connection | ₹1,440.00 (Overcharged +₹840) | Unfair profiteering from tenants | Illegal Resale |
Sub-Meter Calibration & ISI Digital Standard
Never use outdated mechanical rotating-disc meters for sub-tenants. Mechanical meters develop friction over time and can under-read or over-read by up to 25%. Always install ISI-certified digital LCD static energy meters (Class 1.0 accuracy) for each tenant room to prevent meter calibration disputes.
Instant WhatsApp Record & Printable Audit Slip
Always share verifiable digital receipts. By clicking the green WhatsApp button on this calculator, both the landlord and tenant receive an immutable timestamped message detailing previous reading, current reading, blended rate, and total payable amount, establishing complete trust.
