House Wiring Cost in Malaysia: Price Per Point, Packages and What's Included
Most wiring quotes in Malaysia are given as a range, then the final bill grows on site because of "extra cable", "hacking" or "materials". This guide gives you fixed, all-in prices, explains what drives the cost up or down, and shows the Suruhanjaya Tenaga (ST) rules every point must follow, so you can compare quotes properly.
How much does each wiring point cost?
These are Luco Group's published prices for Kuala Lumpur, Selangor and Negeri Sembilan. They are all-in: cable up to 8 metres, conduit or casing, the switch or socket, base box, connection at the DB, testing and the completion certificate.
| Point type | Price (all-in) | Typical cable size |
|---|---|---|
| Light point | RM135 | 1.5 mm² |
| Ceiling fan point (hook included) | RM155 | 1.5 mm² |
| 13A socket point | RM175 | 2.5 mm² |
| Aircond point with DP switch | RM225 | 4 mm² (dedicated) |
| Water heater point with DP switch and RCBO | RM330 | 4 mm² (dedicated) |
| Tapping from an existing point | RM75 | — |
| Extra cable beyond 8 m | RM14 per metre | — |
| Concealed in wall (hacking and plastering) | +RM75 per metre | — |
| Minimum charge per visit | RM650 | — |
You can count your own points and get a total in our home wiring calculator.
Packages
Packages are cheaper when you also want your own lights and fans installed, because installation of up to 15 fittings is included.
| Package | Price | What's included |
|---|---|---|
| Condo package | RM1,680 | 6 lights, 1 fan, 2 sockets, 1 aircond point + install up to 15 of your fittings |
| New home package | RM2,380 | 10 lights, 2 fans, 3 sockets + install up to 15 of your fittings |
| Kitchen package | RM1,180 | 5 points on a dedicated circuit with RCBO, planned before cabinets |
| Install-only package | RM650 | Install up to 15 lights, fans or sockets on existing points |
| Landlord package | RM880 | Replace up to 15 sockets and switches, full safety check, written report |
How do these prices compare with the market?
Published Malaysian prices vary widely, mostly because some quotes exclude cable or hacking:
- Kristal Maya, a Selangor contractor, lists a light point from RM110, a fan from RM180, a 13A socket from RM160 and an aircond point from RM280 (source).
- Wakkiro puts general points at RM80 to RM150 each (source).
- ClickBina quotes RM120 to RM250 for a surface socket and RM200 to RM400 for a concealed one (source).
Our prices sit inside these ranges. The difference is that the number you see is the number you pay, with cable included up to 8 metres per point.
What size of cable does each point need?
ST's Guidelines for Electrical Wiring of Domestic Installations (GP/ST/No.39/2024) sets minimum copper conductor sizes for home circuits in Table 8.2. In summary:
Lighting and fan circuits: minimum 1.5 mm². 13A socket circuits: minimum 2.5 mm². Special power circuits such as aircond, water heater, cooker or pump: 4 mm² to 6 mm² depending on load. Main circuit: 10 mm² up to 40 A, 16 mm² up to 63 A, 25 mm² up to 100 A.
Summary of Table 8.2. Sumber: Suruhanjaya Tenaga (PDF)
Some price websites in Malaysia list 1.5 mm² for "light sockets" or describe 2.5 mm² as standard for lights. Under the ST guideline, any 13A socket circuit needs at least 2.5 mm². A quote that uses thinner cable for sockets is cheaper for a reason.
Socket circuit limits
The same guideline (Table 6.3) limits how much floor area one socket circuit may serve:
| Circuit type | Protective device | Cable | Maximum floor area |
|---|---|---|---|
| Ring circuit | 30 A or 32 A | 2.5 mm² | 100 m² |
| Radial circuit | 30 A or 32 A | 4.0 mm² | 75 m² |
| Radial circuit | 20 A | 2.5 mm² | 50 m² |
This is why adding many sockets to one old circuit is not always allowed: a larger home may need a new circuit from the DB.
What makes wiring more expensive?
- Concealed wiring. Running cable inside the wall needs hacking, a conduit and plastering. That is why concealed work costs about RM75 more per metre than surface casing.
- Long cable runs. A point far from the DB, or upstairs, uses more cable. Our prices include 8 metres; beyond that it is RM14 per metre.
- Dedicated circuits. Aircond, water heater, oven and EV charger points each need their own circuit and protective device at the DB.
- A full or old DB. If there is no spare way in your DB, or it has no RCCB, the DB may need upgrading first. See DB box replacement.
- Condo rules. Many JMBs limit working hours and noise, which affects scheduling.
Worked example: a typical terrace house upgrade
A homeowner adds 4 light points, 3 sockets and 1 aircond point, all surface mounted and within 8 metres of the DB:
| Item | Qty | Price |
|---|---|---|
| Light point | 4 | RM540 |
| 13A socket point | 3 | RM525 |
| Aircond point | 1 | RM225 |
| Total | RM1,290 |
The same job concealed in the wall, with about 2 metres of hacking per point (16 metres), would add 16 × RM75 = RM1,200.
Can I do the wiring myself?
No. Section 4.1 of the ST guideline states that wiring work must be carried out by an electrical contractor registered with the Commission, and section 4.2 requires the wiring plan to be prepared by a competent person. On completion you should receive the Borang G (supervision and completion) and Borang H (test) certificates required under the Electricity Regulations 1994. Learn how to check if a contractor is ST-registered.
Where can sockets go?
The ST guideline (section 6.3) sets safety distances, including:
- Sockets at least 300 mm horizontally from a sink or tap.
- At least 200 mm from a gas outlet.
- Cables run in recognised zones, within 150 mm of the ceiling or wall corners, or straight up and down from an accessory, so they can be found later and are not drilled through.
Frequently asked questions
How much is one light point? RM135 all-in at Luco Group, including up to 8 metres of 1.5 mm² cable, the switch, testing and certification.
Why is there a minimum charge of RM650? Every visit needs travel, isolating the supply, testing the whole circuit and paperwork, whether we install one point or five. RM650 covers up to about 4 light points or 3 socket points, so it is better value to group your jobs.
How long does wiring take? Most additions of 5 to 10 points take one day. A full new-home package of 15 points usually takes one to two days.
Is concealed wiring better than surface casing? Concealed wiring looks cleaner and is protected inside the wall, but costs more and is harder to modify. Surface casing is fine for rental units and quick additions.
Do I need TNB approval to add points? No. Adding points inside your home does not need TNB approval. You only apply to TNB if your total load needs a bigger supply, for example upgrading to three-phase.
