What Is Electrical Wiring?

Electrical wiring is the complete system of cables, conductors, protective devices, sockets, switches, and distribution boards that carries electricity from Singapore's power grid to every appliance, light fitting, and power point in your property. It is the hidden backbone of your entire electrical system.

Under Singapore's Electricity Act and the SS 638 Code of Practice for Electrical Installations, all electrical wiring work — including installing new circuits, adding power points, rewiring, or upgrading a distribution board — must be carried out by or under the direct supervision of an EMA-Licensed Electrical Worker (LEW). Using an unlicensed person is illegal, voids your home insurance, and poses serious safety risks.

Whether your property is a new renovation needing first-time wiring, a resale flat with ageing rubber-insulated cables, a condo needing additional circuits for modern appliances, or a commercial space requiring a full electrical fitout — our team has the licences, equipment, and experience to deliver safe, compliant, and lasting results.

⚠️

Is Your Wiring Over 20 Years Old?

Singapore's Building and Construction Authority (BCA) recommends electrical inspection and rewiring consideration for properties over 20 years old. Old rubber-insulated cables found in pre-1990 HDB and private properties become brittle, crack, and present a serious fire and shock risk. Do not wait for a fault — book a wiring inspection today.

Key Components of an Electrical Wiring System

Every wiring installation or rewiring project involves these four core elements, all of which must meet SS 638 standards.

01
🔌 Conductors & Cables
The copper or aluminum wires that carry electrical current. Modern Singapore installations use PVC-insulated XLPE cables rated for 70°C or 90°C — replacing older, brittle rubber insulation found in pre-1990 properties.
02
⚡ Distribution Board (DB Box)
The heart of your electrical system — contains MCBs (miniature circuit breakers) and RCCBs (earth leakage protection) that protect each circuit. An upgraded DB box is the foundation of a safe modern installation.
03
🔲 Sockets, Switches & Light Points
The visible endpoints — BS1363 13A sockets, DP switches for appliances, and ceiling rose / batten holder connections for lighting circuits. All must be correctly rated and earthed.
04
🌍 Earthing & Bonding
The safety system that connects all metalwork to earth — protecting occupants from shock in the event of a fault. Proper earth continuity and RCD trip-time are tested after every wiring job.

Signs Your Property Needs Rewiring

These are the most common indicators that your electrical wiring has reached the end of its safe service life or can no longer support your electrical load. Do not ignore them.

🔆

Flickering or Dimming Lights

Lights that flicker, dim suddenly or vary in brightness when appliances are switched on indicate loose wiring connections, overloaded circuits, or failing wiring that needs investigation.

Frequently Tripping Circuit Breakers

A circuit breaker that trips regularly is telling you the circuit is overloaded — or that there is a persistent wiring fault. Modern lifestyles demand more circuits than most older HDB and condo installations provide.

🟡

Discoloured or Warm Sockets

Yellow, brown or black marks on socket faceplates, or sockets that feel warm to the touch, indicate dangerous overheating — often caused by loose connections in ageing wiring or overloaded circuits.

🔥

Burning Smell Near Outlets or Walls

A persistent burning or hot-plastic smell is a serious warning of electrical arcing inside the wall or behind sockets. This can lead to a fire. Isolate the circuit and call for inspection immediately.

🏚️

Property Over 20–25 Years Old

Pre-1990 and some pre-2000 properties may still have rubber-insulated cables. This insulation becomes brittle, cracks with age, and can lead to short circuits or earth faults. Full rewiring is strongly recommended.

🔌

Not Enough Power Points

Excessive use of extension leads and multi-adapters is a leading cause of electrical overloads and fires in Singapore homes. The solution is additional power points and circuits — not more adapters.

💡

Old Fuse-Wire Distribution Board

Some older HDB flats still have fuse-wire boards which offer no RCCB/earth leakage protection. These should be replaced with a modern MCB distribution board as a priority safety upgrade.

🔊

Buzzing Sound from Walls or DB Box

A buzzing or humming sound from walls, ceilings or the distribution board indicates electrical arcing or a loose connection inside the system — a fire risk that needs urgent investigation.

😬

Electric Shock or Tingle

Any sensation of electrical current from a switch, socket or appliance indicates an earth fault — missing or broken earthing in the wiring. This is a life-safety issue requiring immediate attention.

🏗️

Post-Renovation Wiring Issues

After major renovations, wiring disturbed by contractors may have loose connections, damaged insulation, or circuits that no longer comply with current SS 638 standards. A post-reno electrical inspection is essential.

Electrical Wiring FAQ

Common questions about electrical wiring, rewiring, and wiring installations in Singapore.

Yes — this is a legal requirement. Under the Electricity Act (Chapter 89A) and EMA regulations, all electrical installation work in Singapore must be carried out by or under the direct supervision of an EMA-licensed Electrical Worker (LEW). This includes installing new sockets, adding circuits, wiring a DB box, and any form of rewiring. Using an unlicensed person can result in a fine of up to $10,000, void your property insurance, and create serious safety risks. All our electricians are EMA-licensed and can issue the required compliance certificates.
The most common signs are: property is over 20–25 years old (especially pre-1990 with rubber insulation cables); flickering lights or dimming when appliances are switched on; circuit breakers that trip frequently; discoloured, warm, or scorch-marked sockets; a burning plastic smell from walls or outlets; buzzing sounds from walls or the DB box; or any sensation of electric tingle when touching switches. We offer a free on-site electrical inspection to assess your wiring condition and give you a factual, professional opinion on whether rewiring is needed.
For a standard HDB flat (3-room to 5-room), full rewiring typically takes 2–5 days depending on flat size, the number of circuits, and the extent of concealed cable routing required. Condo units are similar. Landed properties with 3-phase supply or multiple floors may take 5–10 days. We will advise on the specific duration for your property during the site assessment. Most rewiring is done with residents still able to stay in the property — we restore power at the end of each working day.
All modern rewiring in Singapore uses either PVC-insulated cables (1.5mm² for lighting circuits, 2.5mm² for ring main socket circuits) or XLPE (cross-linked polyethylene) insulated cables for higher-temperature environments. Both comply with SS 638 requirements. Old rubber-insulated cables — found in many pre-1990 HDB and private properties — are replaced entirely, as the rubber insulation becomes brittle and cracks with age, presenting an arc and fire risk.
Some degree of chasing (cutting channels in plaster walls) is usually required to install concealed wiring. In existing properties, we minimise this by making use of existing conduits, junction boxes, and cable routes where possible. Where new chases are needed, our electricians work carefully to minimise the area disturbed. Wall repairs (replastering and painting) are typically handled by your renovation contractor or painter — we recommend coordinating rewiring within a broader renovation project to minimise disruption and cost.
Indicative pricing (2025): 3-room HDB from $2,500; 4-room HDB from $3,200; 5-room/executive HDB from $4,000. These prices include all new wiring cables, DB box upgrade, installation, testing, and the EMA compliance certificate. Exact pricing depends on the current state of your wiring, the number of circuits, and the extent of cable routing required. We provide a free on-site assessment and written quote — no obligation to proceed.
For HDB flats, electrical rewiring works are classified as "approved renovation works" under HDB guidelines. Major electrical works (such as full rewiring or a new DB box) must be carried out by an EMA-licensed contractor and may require an HDB renovation permit if done as part of a broader renovation. Our licensed electricians handle all EMA notification requirements. If your work is part of a full renovation, we coordinate with your renovation contractor to ensure all permits are in order.
Yes — in most cases, additional power points can be added by running new cable from an existing circuit in your DB box, or by extending an existing ring main circuit, without requiring full rewiring. However, this depends on the capacity of your existing circuits and DB box. If your DB box is already full or your existing circuits are near their rated capacity, we may need to add a new MCB slot or upgrade the DB box before adding new points. We assess this during the site visit.
SS 638 is the Singapore Standard for the Code of Practice for Electrical Installations — the primary technical standard that governs how all electrical wiring must be designed, installed, and tested in Singapore. It covers cable sizing, circuit breaker ratings, earthing requirements, RCD protection, testing procedures, and documentation. All our wiring installations comply fully with SS 638. When we issue a compliance certificate after a job, we are certifying that the installation meets this standard — a document you may need for insurance purposes or when selling your property.
After every wiring installation or rewiring project, we perform the following tests as required by SS 638: (1) Insulation resistance test — measures cable insulation integrity; (2) Polarity test — confirms correct line/neutral/earth connections throughout; (3) Earth continuity test — confirms the earth conductor is intact to every accessory; (4) RCD/RCCB trip-time test — confirms earth leakage protection operates within 30ms; (5) Loop impedance test — confirms fault current is sufficient to operate protective devices. Results are documented in a written test report which we provide to you.
Yes — significantly. Insurers in Singapore can reject fire or damage claims if electrical work was carried out by an unlicensed person, or if the installation does not comply with SS 638. An EMA compliance certificate from a licensed electrician is evidence that work was done correctly. For property sales, buyers or their solicitors may ask for evidence of electrical compliance, especially for older properties. A recently rewired property with a current compliance certificate typically commands higher buyer confidence than one with unknown wiring condition.
