MM Engineering Works Pte Ltd (UEN: 202302469E) provides the full scope of regulated electrical services in Singapore — from single-point repairs to whole-house rewiring and commercial fit-outs. Every job is performed by an EMA-qualified Licensed Electrical Worker, fully compliant with the Electricity Act and SS 638.
Electrical services in Singapore refer to the full range of regulated and non-regulated electrical work carried out in residential, commercial, and industrial properties — from simple socket replacements to full rewiring projects, DB box upgrades, emergency repairs, and commercial fit-outs.
Under Singapore's Electricity Act (Cap. 89A), 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). MM Engineering Works employs LEWs of the appropriate class for every job type we take on.

Every electrical service in Singapore is governed by a clear framework. Here's what each body means for you as a property owner or business.
Singapore's regulator for all electrical work. EMA licenses contractors and LEWs, sets technical standards, and enforces the Electricity Act. Only EMA-licensed teams can legally perform regulated electrical work.
The Code of Practice for electrical installations in Singapore. All wiring, circuit design, protection devices, and earthing must comply with SS 638. Non-compliant work can fail inspection and create safety hazards.
Singapore's electricity distribution network operator. Any work involving your main supply connection, metering, or DB supply feed requires SP Group notification and, in many cases, a Licensed Electrical Worker endorsement.
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.
We provide all electrical services islandwide — from Woodlands in the north to Jurong in the west, Tampines in the east, and everywhere in between.
Answers to the most common questions about electrical services, costs, regulations, and choosing the right electrician in Singapore.
Under Singapore's Electricity Act, all regulated electrical work must be performed or directly supervised by a Licensed Electrical Worker (LEW). This includes: new electrical wiring, rewiring, circuit extension or addition, distribution board (DB box) modification or replacement, installation of sub-mains, and any connection to SP Group supply. Non-regulated work — such as replacing a light fixture or socket faceplate on an existing circuit — can be done without an LEW, but it is still advisable to use a licensed contractor for safety and insurance compliance.
Costs vary widely by job type. Common reference prices in Singapore for 2026: a power trip investigation runs $80–$150; a single power socket installation costs $60–$120; an HDB DB box upgrade ranges from $380–$700; a full HDB 4-room rewire costs $1,500–$3,000; a landed house full rewire runs $4,500–$12,000+. All prices exclude GST. We provide free, itemised quotations before commencing any work — call +65 8145 3954 for a quote.
Key signs your home may need rewiring include: frequent power trips that reset themselves, flickering or dimming lights, warm or discoloured switch plates, burning smell near sockets, breakers that trip and cannot be reset, aluminium wiring (common in pre-1990s Singapore homes), or a DB box that still uses old fuse wire instead of MCBs. Properties over 20–25 years old should have an electrical assessment. Call us for a free inspection at +65 8145 3954.
No. Singapore's Electricity Act prohibits unlicensed persons from performing regulated electrical work. Doing so is a criminal offence and can result in fines or imprisonment. More importantly, DIY wiring that is not to SS 638 standard creates serious fire and electrocution risk. Even for non-regulated work such as changing a socket faceplate, incorrect installation can void your home insurance coverage. Always engage a licensed electrical contractor.
SS 638 is Singapore's Code of Practice for Electrical Installations — the technical standard governing how all wiring, circuit protection, earthing, and DB boards must be designed and installed in Singapore. All regulated electrical work must comply with SS 638. Work that does not comply cannot be certified by a LEW, cannot obtain SP Group reconnection after a supply outage, and may fail fire safety or BCA inspections. Every job MM Engineering Works carries out is SS 638 compliant as standard.
Duration depends heavily on job scope. Simple repairs such as power trip diagnosis or socket replacement: 1–3 hours. DB box upgrade: half a day. Full rewiring of an HDB 4-room flat: 2–4 days. Full rewiring of a condo 3-bedroom: 3–6 days. Full rewiring of a landed terrace or semi-D: 5–14 days depending on number of floors and circuits. We provide a realistic timeline with every quotation so you can plan accordingly.
An electrician (or Licensed Electrical Worker / LEW) is an individual licensed by EMA to perform and certify electrical work. An electrical contractor is a company licensed by EMA to engage in electrical work — it employs LEWs and takes contractual responsibility for the works. When hiring for regulated work, you should engage a licensed electrical contractor (like MM Engineering Works) rather than an individual electrician, as the contractor holds public liability insurance and is accountable for the full project.
For most HDB electrical works as part of a renovation, you do not need a separate permit if the works are within your flat and within the approved load. However, any works that involve the main supply, new sub-metering, or changes to the DB box that affect the supply connection require EMA and/or SP Group notification. If you are conducting a full flat renovation, HDB's renovation permit covers most internal electrical works — we advise on the specific requirements for your project scope.
Check five things: (1) EMA contractor licence — verify on the EMA ELISE portal; (2) LEW availability — confirm an LEW will be on-site, not just a sub-contracted worker; (3) written quotation — never accept verbal-only pricing; (4) public liability insurance — ask for confirmation of coverage; (5) testing and certification — confirm they will issue a test certificate upon completion. MM Engineering Works ticks all five. Ask to see our EMA licence number at any time.

MM Engineering Works is an EMA-licensed electrical contractor (UEN: 202302469E). EMA licensing is the qualification framework that governs all electrical work in Singapore, including in HDB properties. HDB requires that all renovation electrical works be done by EMA-licensed contractors — which we are. You can verify our licence status through EMA's ELISE portal. Call us on +65 8145 3954 to discuss your HDB project.
