Emergency response · Free assessment · No obligation
Electrical services in Singapore cover the full range of regulated and non-regulated electrical work performed in residential, commercial, and industrial properties — from a single socket repair to complete house rewiring, DB box upgrades, emergency fault diagnosis, and commercial electrical fit-outs.
Under Singapore's Electricity Act (Cap. 89A), all regulated electrical work — including new wiring, rewiring, circuit extension, and distribution board modification — must be performed or directly supervised by a Licensed Electrical Worker (LEW) holding the appropriate EMA class. MM Engineering Works employs qualified LEWs for every regulated job we undertake.

Most electrical problems have clear warning signs before they become dangerous. Here is what to look for and the correct action to take.
Your circuit breaker trips repeatedly — even after resetting. This indicates an overloaded circuit, a faulty appliance drawing excess current, or deteriorating wiring. Do not keep resetting it — this masks the real problem.
→ Book a fault diagnosisA burning smell from a socket, switch, or DB box, or visible scorch marks around electrical outlets, indicates arcing or a wiring fault. This is a fire risk. Turn off the circuit immediately and call a licensed electrician.
→ Emergency call — do not delayLights that flicker, dim, or buzz often signal a loose connection, an overloaded circuit, or wiring that is deteriorating. Occasional flicker is common — persistent flicker is not normal and should be investigated.
→ Book an inspectionSockets or switches that feel warm to the touch, or that spark when you plug something in, indicate faulty wiring connections or overloaded circuits. These should never be ignored — they are a direct fire and electrocution risk.
→ Stop using the socket — call usWiring in Singapore properties over 15–20 years old may no longer meet current SS 638 standards — especially pre-2000 HDB flats and landed houses. Aluminium wiring (common before 1990) degrades with age and should be replaced.
→ Book a rewiring assessmentUsing multiple extension cords or multi-way adaptors as a permanent solution is a fire risk and a sign your property does not have enough power points for modern usage. The correct fix is adding properly wired power points — not more adaptors.
→ Book a socket installationRequirements vary significantly by property type. Select yours below for the typical scope, regulatory requirements, and cost range.

We visit your property, inspect the electrical installation, and assess scope.
You receive a clear, line-by-line quotation. No hidden fees. No pressure to proceed.
Our EMA-licensed team completes the work to SS 638 standard, on time.
Full electrical testing, documentation, and handover. Job signed off by LEW.
Singapore has one of the strictest electrical safety frameworks in Asia. Understanding the key bodies protects you from illegal work, voided insurance, and real safety risks.
Singapore's regulator for all electrical work. EMA licenses contractors and LEWs, sets technical standards, and enforces the Electricity Act (Cap. 89A). Only EMA-licensed teams can legally perform regulated electrical work. Verify any contractor at EMA's ELISE portal before hiring.
The Code of Practice for Electrical Installations — the technical standard governing all wiring, circuit protection, DB design, and earthing in Singapore. All regulated work must comply with SS 638 to be legally certified. Non-compliant work fails inspection and creates fire risk.
Singapore's electricity distribution network operator. Any work involving your main supply, metering, or DB supply feed requires SP Group notification and an LEW endorsement. For landed house rewiring, SP Group reconnection is required after work is completed.
An individual certified by EMA to perform and certify regulated electrical work. LEWs sign off on the safety certificate for major works. Without an LEW on site, your electrical installation cannot be legally certified — and your insurance coverage may be void.
Not everyone who calls themselves an electrician in Singapore is licensed to do the job legally. Watch out for these warning signs before you hire.
Every legitimate electrical contractor must hold a current EMA electrical contractor licence. If they cannot provide their EMA licence number immediately, do not engage them for regulated work.
Any contractor who refuses to provide a written, itemised quotation before starting work is a red flag. Hidden charges are added after completion — always get the quote in writing first.
Prices significantly below market rate often indicate unlicensed workers, substandard materials, or incomplete work that omits the LEW certification you are legally required to have for regulated works.
After completing regulated electrical work, a properly licensed team issues a test and inspection certificate signed by the LEW. If they do not mention this, your installation has not been legally certified.
Quoting for rewiring or DB work without inspecting the property first is not professional — it means the contractor is guessing at scope, and the final bill will almost certainly exceed the initial quote.
Legitimate contractors require a deposit — not full payment before any work begins. A contractor demanding 100% upfront payment has no incentive to complete the job to the standard promised.
Any licensed electrical contractor can give you their EMA licence number instantly. MM Engineering Works: UEN 202302469E.
Visit ema.gov.sg and search the ELISE (Electrical Licensing Information System) directory.
Enter the contractor's company name or UEN number. The system shows their licence class, status, and expiry date.
Ensure the licence status shows "Active" and covers the class of work you need (e.g., Class LCA for most residential and light commercial works).
MM Engineering Works serves all planning areas and districts — north, south, east, west, and central Singapore. No location is out of range.
Everything you need to know about electrical services, licensing, costs, regulations, and choosing the right contractor in Singapore.
Under Singapore's Electricity Act (Cap. 89A), all regulated electrical work must be performed or directly supervised by a Licensed Electrical Worker (LEW). Regulated work includes: new electrical wiring, rewiring, circuit extension, distribution board modification or replacement, sub-main installation, and any connection to SP Group supply. Non-regulated work — such as replacing a light fixture on an existing circuit — does not require an LEW on-site, but still requires a licensed contractor for insurance and safety compliance.
Common 2025 reference prices: power trip investigation $80–$150; single socket installation $60–$120; HDB 4-room DB box upgrade $380–$700; full HDB 4-room rewire $1,500–$2,800; full condo 3-bedroom rewire $2,500–$5,000; landed house full rewire $4,500–$12,000+. All prices exclude GST and are estimates — the exact cost depends on your property's condition, circuit count, and material requirements. We provide free, itemised written quotations before any work begins. Call +65 8145 3954.
Key signs your home may need rewiring: frequent power trips, flickering or dimming lights, burning smell near sockets, breakers that trip and cannot be reset, warm or discoloured switch plates, buzzing from the DB box, or visible cracked / brittle wiring insulation. Properties over 20 years old — especially pre-2000 HDB flats and landed houses — should have an electrical inspection. Pre-1990 properties may still have aluminium wiring, which degrades with age and should be replaced. Call us for a free rewiring assessment.
No. Singapore's Electricity Act prohibits unlicensed persons from performing regulated electrical work. This is a criminal offence punishable by fines or imprisonment. More importantly, DIY wiring that is not compliant with SS 638 creates serious fire and electrocution risks — and voids your home insurance. Even for seemingly simple non-regulated work such as changing a socket faceplate, incorrect installation can have serious consequences. Always engage an EMA-licensed electrical contractor.
SS 638 is the Singapore Standard Code of Practice for Electrical Installations — the technical standard governing how wiring, circuit protection, earthing, and distribution boards must be designed and installed in Singapore. All regulated electrical work must comply with SS 638 to be certified by an LEW. Work that does not comply cannot be legally certified, cannot obtain SP Group reconnection, and may fail BCA or fire safety inspections. Every job MM Engineering Works carries out is fully SS 638 compliant as standard.
Check five things: (1) EMA contractor licence — verify on the EMA ELISE portal using their company name or UEN; (2) LEW on-site — confirm a Licensed Electrical Worker will be present, not just a helper; (3) Written quotation — never accept verbal pricing only; (4) Public liability insurance — ask for confirmation of coverage; (5) Test certificate — confirm they issue a test and inspection certificate upon completion. MM Engineering Works (UEN: 202302469E) ticks all five — ask to see our EMA licence at any time.
Duration depends on scope: power trip repair or socket replacement: 1–3 hours. DB box upgrade: half a day. Full HDB 4-room rewire: 2–4 days. Full condo 3-bedroom rewire: 3–6 days. Full landed terrace / semi-D rewire: 5–14 days depending on floors and circuit count. Commercial office fit-out: 1–4 weeks. We provide a realistic timeline with every quotation so you can plan renovation schedules accordingly.
A Licensed Electrical Worker (LEW) is an individual certified by EMA to perform and certify regulated work. An electrical contractor is a company licensed by EMA to engage in electrical work — it employs LEWs and takes contractual and legal responsibility for the works, including insurance coverage. For regulated work, always engage a licensed electrical contractor (not just an individual LEW) — the contractor holds public liability insurance and is accountable for the full project scope.
For most HDB renovation electrical works within your flat and within approved load limits, a separate electrical permit is not required beyond HDB's standard renovation permit. However, any works involving the main supply, new sub-metering, or DB box changes that affect the supply connection require EMA and/or SP Group notification. If you are undertaking a full flat renovation, HDB's renovation permit covers most internal electrical works — we advise on the specific requirements for your exact project scope at the assessment stage.
