Electrical wiring in Singapore
Electrical wiring is the network of cables, circuits, and connection points that carries power safely from your DB box to every socket, light, and appliance in your home. House wiring covers the live, neutral, and earth conductors, the circuit protection in your distribution board, and the points they feed. Most homes need new wiring added when they extend circuits, add power points, or fit higher-load appliances. A full rewire is different: it replaces ageing or deteriorating wiring throughout the property, and it is usually called for in older flats and houses where insulation has degraded, the system trips repeatedly, or the wiring no longer meets current standards. All wiring and rewiring work in Singapore must be carried out by an EMA Licensed Electrical Worker (LEW).
Rewiring for your home
Work with our licensed electricians to safely replace old or failing wiring throughout your property, whether it is an aging HDB flat, an older condo, or a heritage landed house.
- Safety assessment and diagnostics to find wiring hazards, deterioration, and load limits before we start, following HDB guidelines for electrical works.
- Complete house rewiring from the circuit board to individual outlets, bringing the whole system up to modern safety standards.
- Electrical load upgrades with new circuit breakers and wiring to handle today's appliances and smart-home demands.
Rewiring for business
We carry out commercial rewiring for offices, retail outlets, and F&B venues with aging systems, and we plan the work to keep your business running. From assessment to a full overhaul, we bring your property up to Singapore's latest safety standards.
- Detailed commercial electrical assessments covering wiring weaknesses, capacity limits, and compliance gaps.
- Phased rewiring plans that replace old infrastructure with minimal disruption.
- Distribution board (DB) upgrades with modern circuit protection and power management.
- Backup power integration for critical operations.
- Compliance certification and documentation against Singapore's latest electrical codes.
Types of rewiring we provide
Not every property needs a full rewire. We match the approach to your situation.
- Complete house rewiring: replaces all cabling, ideal for older homes or major renovations.
- Partial rewiring: updates specific areas or circuits that need attention.
- Circuit-specific rewiring: targets overloaded or damaged circuits without a full-scale job.
- Commercial rewiring: for business premises needing higher capacity and specialised configurations.
Our whole-house rewiring process
We begin with a detailed assessment of your current wiring, noting safety concerns and the best approach for your property. Installation follows strict safety steps, including temporary power to limit disruption, careful removal of old wiring, and proper routing of new cables in line with Singapore standards and HDB guidelines for electrical works. We then test every circuit, confirm earthing and safety mechanisms, and hand over certification documents plus maintenance advice.
Common problems we fix
Old wiring causes everyday headaches. We solve the root cause, not just the symptom.
- Frequent breaker trips from overloaded, outdated wiring: fixed with properly rated circuits that share the load.
- Intermittent power from aged cables and worn connections: replaced with reliable modern wiring.
- Exposed or damaged wiring that poses fire and shock risks: removed through full system replacement.
- Wiring that cannot support modern appliances: upgraded to handle current and future demand.

Frequently asked questions
How do I know if my property needs rewiring?
Warning signs include frequent breaker trips, flickering lights, burning smells, warm outlets, or shocks from appliances. Older HDB flats and homes with decades-old wiring are common candidates. We start every job with a safety assessment and diagnostics to confirm what is needed. If a full rewire is not necessary, we will tell you.
How disruptive is a full rewiring project?
We plan the work to keep disruption low, using temporary power arrangements and phased scheduling around your daily routine. For businesses we can schedule after-hours work and track progress so operations keep running. The exact impact depends on your property size and scope. We explain the plan before we begin.
Can you rewire without replacing the walls?
In many cases yes, using careful cable routing suited to your property type, including limited HDB ceiling spaces. The approach depends on your building's construction and how the existing wiring runs. We assess this during the initial inspection. We always aim to minimise structural disturbance.
How long does a rewiring project take?
It depends on the property size and whether it is a full, partial, or circuit-specific rewire. After our assessment we give you a clear timeline for your specific job. We work efficiently while keeping safety standards high. Partial and circuit-specific work is usually quicker than a complete rewire.
Will rewiring lower my electricity bills?
Modern cables reduce electrical losses and improve power distribution, which can lower your bills over time. New wiring also supports your appliances without overloading circuits, which protects equipment from damage. The savings depend on your old system and usage. We can advise on the likely benefits during assessment.
