In the dense urban landscape of Makati City, sub-metering is a standard practice in multi-tenant commercial buildings, residential condominiums, and "bedspace" apartments. However, the lack of clarity regarding the legality of "mark-ups" often leads to disputes between lessors and lessees. Under Philippine law, the resale of electricity is a highly regulated activity, and landlords are strictly bound by the rates set by the Energy Regulatory Commission (ERC) and the franchises of distribution utilities like MERALCO.
1. The Proportionality Principle: The "Pass-Through" Rule
The fundamental principle governing sub-metering in the Philippines is that a landlord or building owner cannot act as a profit-making utility. Under the Electric Power Industry Reform Act of 2001 (RA 9136), or EPIRA, only entities with a national franchise are authorized to distribute and sell electricity to end-users at a profit.
For tenants in Makati, this means:
- No Mark-ups: Landlords are prohibited from adding a "surcharge" or "profit margin" on top of the cost per kilowatt-hour (kWh) charged by MERALCO.
- Exact Recovery: The landlord is only entitled to recover the actual cost of electricity consumed by the tenant, as reflected in the main billing of the distribution utility.
2. Components of the Electricity Bill
A common point of contention is how the "rate" is calculated. A MERALCO bill is not just the generation charge; it includes transmission, distribution, subsidies, and government taxes (VAT).
In a sub-metered setup, the legal rate is typically calculated as: $$\text{Total Amount Due on Main Bill} \div \text{Total kWh Consumed by Entire Building} = \text{Effective Rate per kWh}$$
The landlord must apply this effective rate to the tenant's sub-meter reading. Any attempt to charge a flat "commercial rate" (e.g., charging ₱20/kWh when the effective rate is ₱12/kWh) is a violation of ERC regulations.
3. Administrative and Maintenance Fees
Landlords often argue that sub-metering entails costs, such as meter reading, maintenance of electrical infrastructure, and "system loss" (electricity lost due to heat in the wiring).
- System Loss: While distribution utilities are allowed a certain percentage of system loss, landlords generally cannot pass this on to tenants as a hidden mark-up.
- Service Fees: If a landlord wishes to charge for the administration of the billing, this must be billed as a separate administrative fee or incorporated into the monthly rent/association dues. It cannot be bundled into the electricity rate itself.
4. Relevant Regulatory Bodies and Laws
Several legal instruments protect tenants in Makati from overcharging:
| Regulation/Law | Core Protections |
|---|---|
| RA 9136 (EPIRA) | Regulates the industry and ensures that only franchised utilities can set distribution rates. |
| Magna Carta for Residential Electricity Consumers | Provides consumers the right to transparent billing and accurate metering. |
| ERC Resolution No. 20 (Series of 2011) | Governs the supply of electricity in "Managed Localities" (like condos and IT parks), stressing that rates must not exceed the DU's approved rates. |
5. Common Illegal Practices in Makati Rentals
In many residential areas of Makati (such as Brgy. Pembo, Guadalupe, or Pio del Pilar), informal sub-metering is rampant. Tenants should be wary of:
- Fixed Rates: Charging a flat monthly fee (e.g., ₱1,500/month) regardless of actual consumption, unless it is a clear, all-inclusive rental agreement.
- Rounding Up: Rounding the MERALCO rate up to the nearest whole number for "convenience."
- Penalty Rates: Charging a higher electricity rate as a penalty for late rent payment.
6. Remedies for Overcharged Tenants
If a tenant in Makati suspects they are being overcharged for electricity through a sub-meter, the following steps are legally available:
- Request for Transparency: Under the principle of "Full Disclosure," a tenant has the right to see the main MERALCO bill of the building to verify the effective rate.
- Mediation via the Lupon Tagapamayapa: For residential disputes, the first step is often the Barangay level. Makati’s barangays have the authority to mediate disputes regarding overcharging.
- Formal Complaint with the ERC: The Energy Regulatory Commission’s Consumer Affairs Service (CAS) handles complaints regarding illegal resale of electricity. If the landlord is found to be "profiteering" from electricity, they can be ordered to refund the excess charges and pay administrative fines.
- Business Permit Violation: In Makati, businesses (including lessors) must operate within the law. Overcharging on utilities can be grounds for a complaint with the Makati Business Permits and Licensing Office (BPLO) for unfair business practices.
Summary Checklist for Makati Tenants
- Verification: Does the rate on your receipt match the effective rate of the building's main MERALCO bill?
- Separation: Are "admin fees" or "maintenance" listed separately from the kWh consumption?
- Documentation: Do you have a record of monthly sub-meter readings signed by both parties?
A sub-meter is a tool for fair distribution of costs, not a source of revenue for the property owner. Any deviation from the actual cost of power is a violation of Philippine energy regulations.
