Can landlords legally charge ₹10, ₹12, or commercial rates to tenants?
One of the most widespread conflicts between Indian tenants and property owners is utility tariff markups. Landlords often charge a flat ₹10, ₹12, or ₹15 per unit, claiming it covers common areas and wiring maintenance, even when the state DISCOM slab rate is only ₹5 to ₹7. The Legal Verdict: It is strictly illegal for residential landlords to profit from electricity reselling. Under Sections 126 and 135 of the Electricity Act 2003, no person without an authorized distribution license may resell electricity or charge tariffs exceeding the actual blended rate billed by the state DISCOM (BESCOM, MSEDCL, TANGEDCO, Tata Power, TSSPDCL, WBSEDCL). State Electricity Regulatory Commissions (SERCs) have repeatedly penalized property owners for charging arbitrary commercial rates on domestic connections.

Is sub-meter installation illegal in India?
There is widespread confusion on whether installing sub-meters is permitted under Indian electricity laws. Here is the legal distinction:
Why tiered slab rates cause tenant disputes (The Math Problem)
Most state electricity boards use tiered progressive slab tariffs — the more total electricity consumed through the main meter, the higher the rate per unit. For Example (Karnataka BESCOM / MSEDCL typical slab): - First 100 units: ₹4.50 / unit - 101 to 200 units: ₹6.00 / unit - 201+ units: ₹8.50 / unit When 3 or 4 tenants share a single main meter, their combined usage pushes the main bill into the highest slab. If a landlord bills everyone at the lowest slab, the owner loses money; if the landlord bills everyone at a high flat rate (e.g. ₹12), the tenants feel cheated.
The Fair Formula: Calculating Weighted Average Cost Per Unit
The only legally sound and dispute-free method is the Blended Effective Rate Formula: Step 1: Effective Rate Per Unit = Total DISCOM Bill Amount (including energy charges, fixed charges, and electricity duty) ÷ Total Units Consumed on Main Meter. Step 2: Tenant Sub-Meter Bill = (Tenant Units Consumed on Sub-Meter × Effective Rate Per Unit) + (Common Area Share). Step 3: Common Area Share = (Total Main Meter Units - Sum of All Tenant Sub-Meter Units) × Effective Rate Per Unit ÷ Number of Occupants/Rooms.

State-by-State DISCOM Rules & Tenant Subsidies (2026)
Electricity policies vary significantly across Indian states:
Handling Common Areas, Water Pumps & Lifts
Common-area electricity (stairwells, water pumps, lifts, exterior perimeter lighting) should never be disguised inside an inflated per-unit room rate. The recommended practice is either: 1. Include common power in a fixed monthly society or maintenance fee (e.g. ₹500/month). 2. Install a dedicated sub-meter for the water pump/lift and split the net units equally among all units.
Move-Out Utility Settlements & Deposit Protection
One of the most frequent reasons security deposits get held up is waiting 3 to 4 weeks for the DISCOM bill to arrive after a tenant moves out. To resolve this cleanly: - On move-out day, take a photo of the sub-meter reading in the tenant's presence. - Compute interim consumption: Units Consumed × Last Month's Blended Unit Rate. - Deduct the interim amount immediately and issue the balance security deposit on the spot, avoiding weeks of follow-up.
