What does an electrical contractor in Singapore do?+
An electrical contractor plans, installs, repairs, and upgrades electrical systems for homes, offices, and commercial properties — wiring, DB box upgrades, power points, lighting circuits, and safety testing. Under Singapore's Electricity Act, a Licensed Electrical Worker (LEW) certified by EMA must carry out or supervise all regulated works, and test the installation's safety before the supply is switched on.
Do I need a licensed electrician for electrical work in Singapore?+
Yes — it's a legal requirement. Singapore's Electricity Act (Cap. 89A) requires all regulated electrical work to be carried out or supervised by an EMA-Licensed Electrical Worker (LEW). Unlicensed work is illegal, can void your home insurance, and is a genuine fire risk. Always ask to see the EMA license card before any work starts — every valid LEW carries one.
How much does electrical work cost in Singapore?+
Costs vary by scope: power point installation from $80, DB box upgrade from $300–$800+, HDB whole-house rewiring $1,500–$4,000, and landed house rewiring from $4,000 upward. We give you a clear, itemised written quote after a site assessment — so what you agree to is what you pay.
How fast can you respond to an electrical emergency in Singapore?+
We operate 24/7, including weekends and public holidays. For emergency callouts, we aim to reach most locations in Singapore within 45 to 90 minutes. The fastest way to reach us is via WhatsApp at +65 8145 3954 or by calling directly. If you smell burning or see sparks, please first turn off your main switch at the DB box, then contact us immediately.
Do you work with renovation companies and interior designers?+
Yes — and this is one of our core strengths. MM Engineering Works regularly acts as an electrical subcontractor for renovation firms, interior designers, main contractors, and builders across Singapore. We coordinate closely with your team, fit into your project timeline, and communicate clearly so that electrical work never holds up the rest of your renovation.
When should I upgrade my DB box in Singapore?+
Consider a DB box upgrade if your property has an old rewirable fuse board, you frequently trip breakers after adding appliances, you're installing new aircon units or an EV charger, or your property is more than 20 years old and hasn't had an electrical overhaul. Modern MCB and RCCB panels are significantly safer and built for today's higher household electrical loads.
Can you handle both HDB and landed house electrical works?+
Yes. We handle electrical works for all property types in Singapore — HDB flats (BTO and resale), condominiums, terrace houses, semi-detached homes, bungalows, and commercial premises. Each has different load limits, wiring constraints, and compliance requirements. Our team knows them all and approaches each property type accordingly.
What warranty do you provide on electrical work?+
MM Engineering Works provides a 90-day workmanship warranty on all installation and repair work. If the same fault recurs within that period due to our workmanship, we return and rectify it at no additional charge. We also remain reachable by WhatsApp after any job — and we walk you through everything we did before we leave, so you're never left wondering what happened or why.
