Introduction
Planning electrical work in your home? Whether you're renovating an old property or installing wiring in a brand-new house, knowing the costs involved can help you budget wisely. In areas like Klang Valley, Selangor, and Kuala Lumpur, electrical work is a critical investment—but the price can vary greatly depending on your project's nature.
Let's break down the costs of rewiring an old home versus setting up a new electrical system!
Why Electrical Work is Crucial in Any Home 🔌
Electrical wiring ensures safety, comfort, and convenience. Faulty or outdated wiring can pose fire hazards, cause frequent power trips, or damage appliances. A modern and compliant setup not only keeps your home safe but also adds to its market value, especially in high-demand property zones like KL and PJ.
Rewiring an Old Home: What to Expect in Selangor & KL 🏡
1. Scope of Work
Rewiring an old house often includes:
Removing outdated or damaged wiring
Installing new wiring, sockets, switches
Upgrading the distribution board (DB)
Ensuring compliance with current safety standards (e.g., Suruhanjaya Tenaga regulations)
2. Estimated Cost
In Klang Valley, rewiring costs for a standard single-storey home (1,000–1,200 sq ft) range from RM4,000 to RM8,000 depending on complexity, materials used, and your location (e.g., central KL may cost more due to higher labour rates).
3. Hidden Challenges
Wall hacking and restoration work
Asbestos or old insulation materials
Limited access in older building layouts
⇝These issues are more common in mature areas like Ampang, Cheras, or Petaling Jaya and can add to both cost and time.
New Electrical Setup for a New Build in Klang Valley 🏠
1. Scope of Work
A new installation includes:
Planning and laying all wiring routes
Installing DB, switches, sockets, lighting points
Integration with smart home systems (optional)
2. Estimated Cost
For a similar-sized home (1,000–1,200 sq ft), a new setup in Selangor or Kuala Lumpur typically costs RM3,000 to RM6,000. Prices can rise if you opt for:
Concealed wiring
Smart systems
Premium fittings and finishes
3. Easier Execution
Since there's no demolition or retrofitting, new installations are quicker and cleaner, with fewer surprises—a common choice in newly developed areas like Setia Alam, Cyberjaya, or Kajang.
Comparing Time and Disruption ⏱️
1. Project Duration
Rewiring an old home in Selangor or KL typically takes 5–10 days, sometimes longer if structural work is needed.
A new electrical setup may be completed in 3–5 days, especially when coordinated during the construction phase.
2. Disruption to Daily Life
Rewiring can be noisy and dusty, often requiring temporary relocation.
New installations are generally clean and fast, with less interruption.
3. Planning Ahead
To reduce downtime, schedule work during weekdays and inform neighbours if living in close quarters like condos in KL.
Key Factors That Affect the Cost 💸
Property age and condition
Accessibility of wiring routes
Quality of materials (e.g., copper vs aluminium wiring)
Type of DB and safety features
Labour rates in your area (central KL is typically more expensive)
Add-ons like smart home tech or surge protectors
Did You Know? ❓
In Malaysia, all electrical installations above 100A must be certified by a Competent Person registered with the Energy Commission (Suruhanjaya Tenaga). Always hire licensed electricians—especially in high-risk zones like dense KL high-rises or older Selangor terrace homes.
Conclusion: Budget Smart, Choose Wisely ✅
Whether you’re upgrading an old home in Shah Alam or setting up a new unit in Mont Kiara, understanding your electrical needs and budget is essential. Rewiring may cost more due to complications, but it's necessary for safety. New setups are typically cheaper and simpler but still require careful planning.
