Planning electrical work in your home or office and wondering what the electrical installation cost in Singapore actually looks like in 2026? You are in the right place. Whether you are renovating an HDB flat, fitting out a condominium, or upgrading a commercial space, understanding the true cost of electrical installation in Singapore helps you plan your budget confidently — and avoid being overcharged.
In this comprehensive guide, MM Engineering Works, a licensed electrical contractor in Singapore, clearly, honestly, and in full detail breaks down the cost of every major electrical installation. No vague estimates. No hidden surprises.
Before we share the numbers, it is important to understand why electrical installation costs in Singapore vary from project to project. Several key factors determine your final price:
1. Property Type HDB flats have simpler wiring layouts and shorter cable runs, making them more affordable. Condominiums, landed properties, and commercial premises involve more complex wiring, higher loads, and sometimes three-phase supply — all of which add to the cost.
2. Scope of Work: A single power point installation costs far less than a complete rewiring project. The more points, circuits, and DB box upgrades involved, the higher the electrical installation cost.
3. Licensed Electrical Worker (LEW) Requirements Under Singapore’s Electricity Act, all fixed electrical work must be performed by an EMA-licensed electrical contractor supervised by a Licensed Electrical Worker (LEW). This is non-negotiable — and rightfully so. LEW certification, BB33 sign-off, and SP Group submissions may be required for larger projects, adding professional fees.
4. Materials and Brand Quality of switchgear, cables (XLPE vs PVC), and circuit protection devices (RCCB, MCB) all affect cost. Reputable licensed contractors like MM Engineering Works use materials that meet SS 638:2018 standards.
5. Accessibility and Hacking Concealed wiring requires wall chasing and patching. If hacking is involved, costs increase for both labor and reinstatement.
HDB flats remain the most common type of residential property in Singapore. Here are the typical electrical installation costs for HDB units in 2026:
| Work Type | Estimated Cost (SGD) |
|---|---|
| Single power point installation | $80 – $150 |
| Single light point installation | $60 – $120 |
| DB box upgrade (standard) | $400 – $800 |
| Full HDB rewiring (3-room) | $2,000 – $4,000 |
| Full HDB rewiring (4-room) | $3,000 – $5,500 |
| Full HDB rewiring (5-room / EA) | $4,000 – $7,000 |
| Circuit breaker replacement | $80 – $200 |
| Air-con dedicated circuit | $150 – $300 per unit |
Important: HDB electrical works must comply with HDB renovation guidelines. All works require a Licensed Electrical Worker (LEW). MM Engineering Works handles all LEW certification and submission on your behalf.
Condo electrical installation in Singapore involves additional considerations — MCST approval, restricted working hours, and often more complex wiring layouts. Expect costs to be 15–30% higher than equivalent HDB work.
| Work Type | Estimated Cost (SGD) |
|---|---|
| Full condo rewiring (2-bedroom) | $3,500 – $6,000 |
| Full condo rewiring (3-bedroom) | $5,000 – $9,000 |
| DB box upgrade | $500 – $1,200 |
| PowerPoint additions | $100 – $180 per point |
| Lighting point additions | $80 – $150 per point |
| EV charger installation (condo carpark) | $800 – $2,500 |
MM Engineering Works manages all MCST documentation and coordinates directly with your condo management office.
Landed properties — terraced, semi-detached, and bungalows — typically involve three-phase supply, higher electrical loads, and more extensive wiring runs. Electrical installation costs are correspondingly higher.
| Work Type | Estimated Cost (SGD) |
|---|---|
| Full house rewiring (terrace) | $6,000 – $12,000 |
| Full house rewiring (semi-D / bungalow) | $10,000 – $20,000+ |
| Three-phase DB box upgrade | $1,200 – $2,500 |
| EV charger installation (landed) | $600 – $1,800 |
| Outdoor electrical points | $150 – $300 per point |
Commercial electrical installation in Singapore — offices, retail units, F&B outlets, factories, and warehouses — involves higher load requirements, three-phase supplies, and tenant fit-out specifications set by landlords.
| Work Type | Estimated Cost (SGD) |
|---|---|
| Office fit-out electrical (per sq ft) | $8 – $25 |
| Retail unit electrical fit-out | $3,000 – $15,000+ |
| Factory / warehouse electrical | $5,000 – $30,000+ |
| Three-phase DB installation | $1,500 – $4,000 |
| Commercial lighting installation | $50 – $200 per point |
