How Much Does It Cost to Upgrade to 3 Phase or Downgrade to 1 Phase?

There are 3 types of charges you need to know:

1. Site Work Costs (Upgrade/Downgrade Works)
Charges for changing the meter board, DB, meter panel, and related works for an upgrade depend on site conditions.
Typically RM 1xxx – RM 3xxx, and may be higher if the installation is underground.

2. TNB Charges (Connection, Deposit & Stamp RM 10)
TNB charges depend on the existing deposit and type of connection. You will receive a TNB invoice after approval.

Consumer Connection Charge (CSP): Calculated based on the difference from the existing 1-phase supply.

• Overhead line (3 Phase): RM 750
• Overhead line (1 Phase): RM 450

• Underground line (1 Phase & 3 Phase): up to RM 1,700

• 3-Phase Meter Deposit: Between RM 400 to RM 1,600, depending on the type of premises and electrical demand

Example 1: Upgrade Cost for a 2-Storey Terrace House

Previous 1-Phase Payment
Deposit: RM 500
Connection charge: RM 450

3-Phase Upgrade Payment

Standard connection charge for new 3-phase overhead supply: RM 750
Connection charge already paid for existing 1-phase overhead supply: RM 450

RM 750 – RM 450 = RM 300
Additional CSP payable: RM 300

Deposit
New 3-phase deposit for a terrace house: RM 700
Existing 1-phase deposit paid: RM 500

RM 700 – RM 500 = RM 200
Additional deposit payable: RM 200

Stamp Duty: RM 10

Total Payment to TNB:
RM 300 (CSP)
RM 200 (Deposit)
RM 10 (Stamp)
= RM 510

* This amount does not include additional charges that may be imposed for extra works required, such as compliance with local council requirements for Horizontal Directional Drilling (HDD), milling, or road reinstatement works.

* For all load change applications, additional security deposit may be required due to the expected increase in electricity bills. Please check with any TNB Kedai Tenaga for more details on charges related to load changes.

3. Electrical Contractor Charges (Registration & Management)

• Charges by a registered electrical contractor (application forms, testing, official submission):
