Regulatory Storm in the Rental Market: Analysis of the New Electricity Bill System for Rentals in 2026
In the rental markets in Taipei and New Taipei, many landlords will divide old apartments into multiple "shared suites" or "private rooms" for rent. In the past, because there was only one main electricity meter for the whole floor of the house, and multiple suites shared the same bill, landlords would often stipulate in the contract that "the electricity bill would be charged 5 yuan, 6 yuan, or even 7 yuan per kilowatt hour in summer" in order to facilitate calculation. However, the "New Regulations on Standardized Residential Lease Contracts" announced by the Ministry of the Interior have officially come into effect, which imposes extremely strict restrictions on the calculation and collection of electricity bills for rentals: If it is not billed by the meter, the total amount of electricity bill collected shall not be higher than the total amount of the Taipower electricity bill for that period.
After the new system is implemented, tenants have the right to directly inquire the current electricity bill details from Taipower based on their lease. If the landlord continues to use the past illegal collection method of "a fixed charge of 6 yuan per time", once reported, he will face direct fines from the Consumer Protection Department and the Land Bureau, and penalties can be imposed on a case-by-case basis. This regulatory change brings huge compliance risks to renters who own multiple suites and to businessmen looking to acquire rental properties. To solve this pain point, the only way out is to carry out "compliance transformation of water and electricity submeters and electricity meters."
Option 1: Hard restrictions and procedures for applying for "independent electricity meters" from Taipower
The once-and-for-all and most uncontroversial solution is to apply for "independent electricity meters" from Taipower for each suite. In this way, each tenant will receive his or her own exclusive Taipower bill and pay according to usage. The electricity price is completely calculated by Taipower. However, the qualifications for applying for Taipower's independent electricity meter are extremely strict, and it is often difficult to pass the renovation of old apartments:
1. House number and entrance and exit restrictions: The prerequisite for applying for an independent electricity meter is that "the space must have an independent house number" and must have "an independent entrance and exit that does not pass through other people's residences or directly to public corridors or streets." If your suite passes through the shared entrance as soon as you enter the door and then is divided into each room, Taipower will directly return the package during on-site inspection.
2. The visa must be submitted for review by a qualified contractor (Class A electrician): The application process involves circuit drawing, wiring changes in the house and safety visa. You must entrust a qualified local hydropower engineering firm in Taipei or New Taipei to submit the application to the Taipower Sales Office.
3. Line reorganization and removal costs: Each meter requires an independent set of power trunk lines, and a meter box is set up in the public area downstairs (such as the stairwell on the first floor). If there is no reserved space in the old apartment, the plumber and electrician will need to build walls and draw pipes. The construction is extremely difficult and requires the consent of the building management committee or all residents.
Option 2: Legal billing guide for privately setting up "digital sub-meters (sub-meters)"
If you are unable to apply for an official independent electricity meter from Taipower due to the layout and house number, the compromise solution commonly adopted by landlords is to "install private sub-meters". This is to install second-hand or new "single-phase three-wire digital submeters (small meters)" for each suite's circuit behind the main box to record the power in each room. In the case of privately installed electricity sub-meters, how to charge fees legally without stepping on the red line of 300,000 fines? The following is the standard process:
1. The contract stipulates that "charges will be charged by the meter and Taipower bills will be provided":The landlord cannot write in the contract 6 yuan per unit. After the bill is mailed, the total bill amount of Taipower (for example, NT$ 8,000) must be divided by the total electricity consumption (for example, 1,600 kilowatt hours) to calculate the average unit price for the current period to be NT$5 per kilowatt hour. Then, based on the electricity consumption on the tenant's submeter (for example, 300 kilowatt hours), multiply it by 5 yuan and charge NT$ 1,500. And when charging, take the initiative to attach a photo of Taipower's original bill to show credibility.
2. Choose electric meters that have passed CNS national inspection: Private electric submeters must use electric meters printed with the "same-shaped" certification mark of the Bureau of Standards and Inspection (such as single-phase three-wire 220V/110V shared type). If you use an untested cheap electricity meter, consumer disputes may arise due to inaccurate measurement, and there may even be safety hazards such as overloading and fire.
Submeter project budget and commercial ROI return on investment analysis
The cost of water and electricity submeter renovation in the greater Taipei area will vary greatly depending on the plan:
1. Private digital submeter project:
Including adding a dedicated fuseless switch in the main electrical box, configuring branch pipes, and installing CNS qualified digital meters outside each room. Taking an apartment with four suites as an example, a reasonable construction quotation including work and materials is approximately between NT$ 15,000 and NT$ 28,000, and the construction period can be completed in about 1 to 2 days.
2. Apply for Taipower independent electric meter project (if qualified):
Includes Class A contractor drawing and visa fees, Taipower regulations fees, construction of downstairs main meter box, external main cable re-traction and wall drilling. For the same size of 4 suites, the overall project quotation in Shuangbei is usually as high as NT$ 120,000 to NT$ 220,000.
[Perspectives of businessmen and acquirers: Compliance will increase property value]
When evaluating the acquisition of a whole building or a whole floor apartment in Shuangbei, A rent-collecting property that has fully completed Taipower's independent sub-metering, or has a clear and qualified sub-metering billing system, can completely avoid the regulatory risks of future tenant complaints and consumer protection officer fines (30,000-300,000), and can provide extremely transparent historical operating data. Compliant properties can attract better-quality long-term tenants who are willing to pay a premium in the market, reduce the vacancy rate, and make the net operating income (NOI) of the property more stable, thereby creating a higher capitalization rate (Cap Rate) and asset appreciation return when the property is resold.
The Ministry of Economic Affairs' latest "Regulations on Consumer Electrical Equipment Installation" and the key points of electricity safety in old houses
Due to the popularity of high-power household appliances (such as air fryers, microwave ovens, dishwashers, instantaneous electric water heaters, and IH furnaces) in recent years, the Energy Administration of the Ministry of Economic Affairs has revised the "Regulations on Consumer Electrical Equipment Installation" many times to strictly require the diversion and protection mechanisms of residential electricity circuits. Statistics show that more than 30% of building fires in Taiwan are caused by electrical factors, among which "old wire insulation deteriorates and short circuits", "socket contacts are oxidized and loose, poor contact" and "non-fuse switch (NFB) overloaded and failed to trip" are the three main fatal causes.
Old apartments in Shuangbei that are more than 30 years old have a total original designed power capacity of only 30A to 40A, and several rooms often share the same 1.6mm or 2.0mm circuit. In the modern standard safety configuration, kitchen electrical cabinets, bathroom equipment, and air-conditioning and heating machines must all be equipped with 5.5mm² dedicated circuits (single circuit and single socket). It is recommended that the main switch box be upgraded to a busbar (Busbar) integrated distribution board, and the total amperage is increased to 75A or 100A (a qualified electrical appliance contractor needs to be entrusted to Taipower to review the additional power capacity).
Residential electricity self-test and regular inspection checklist
- Appearance and temperature of the socket: Touch the outer cover of the commonly used socket lightly with the back of your hand. If it feels lukewarm or if you find that the plastic socket is yellowed and charred, or the plug is loose and shaking after being plugged in, it means that the internal copper plate clamping force is exhausted or the contact resistance is too high, and you should immediately cut off the power and replace it.
- Regular testing of leakage circuit breakers (ELCB): For leakage circuit breakers in humid places such as balconies, bathrooms, and kitchen sinks, regulations require that the "TEST button" on the switch be pressed once every 1 to 3 months to confirm that it can automatically trip and cut off the power supply instantly.
- Serial connection and overloading of extension cords are strictly prohibited: Extension cords should be purchased with 2.0mm thick wire diameter products that have CNS certification and automatic overload power-off protection. Do not share the same extension cord with high energy-consuming appliances to ensure zero hidden danger to life and property at home.
