9 Best Electricians in Singapore (August 2026)

The single most important thing to understand before you hire anyone: in Singapore, a lot of electrical work legally requires a Licensed Electrical Worker (LEW) registered with the Energy Market Authority (EMA). This is not the same as a general handyman who happens to own a screwdriver and a voltage tester. Wiring works, DB (distribution board) box changes, consumer unit replacements, and any power supply upgrade must be carried out or supervised by a LEW. You can verify a worker on the EMA ELISE portal by name or licence number, and any reputable company will give you a LEW ID on request before work starts.

So where is the line? A handyman can usually replace a like-for-like light fitting or swap a plug top. But fault finding on a tripping circuit, installing a new socket on a new wiring run, changing or upgrading your DB box, rewiring a flat, and wiring up high-load appliances like a water heater or an EV charger all sit firmly in licensed-electrician territory. Get those wrong and you risk a fire, an electric shock, or an installation that fails inspection.

The most common jobs I see homeowners call an electrician for are: power trips and fault finding (the breaker keeps tripping and nobody knows why), light and ceiling fan installation, adding or repairing sockets and switches, DB box changes, partial or full rewiring, and dedicated wiring for water heaters and EV chargers. Two of those overlap with other trades. Water-heater swaps often pair with a plumber (see my best plumbers in Singapore list), and aircon installs involve electrical work too, which is why I cover that separately in my best aircon servicing in Singapore guide. For anything touching fixed wiring or your DB box, hire a LEW.

Electrical pricing in Singapore is fairly consistent across reputable firms, and most of the variation comes down to whether wiring is surface-run or concealed (concealed work means hacking, which adds cost) and whether the job is during office hours or an after-hours emergency. Here are the typical 2026 ranges I would budget for. Treat them as a guide, not a fixed quote, and always get the price confirmed in writing before work starts.

Emergency and late-night call-outs usually carry a surcharge, and parts (a new breaker, socket, or fan) are billed on top of labour. The biggest swing is rewiring, where a small partial job might be S$1,000 while a full 4-room HDB rewire runs S$3,500 to S$5,500. If a quote comes in far below these ranges, ask whether a LEW is actually doing the work.

1. LEW licensing where it is required. For any fixed wiring, DB box change, or power upgrade, the work must be done or supervised by an EMA Licensed Electrical Worker. I expect a company to give a LEW ID on request, and I would walk away from anyone who dodges the question.
2. A transparent, written quote. The price should be confirmed before work starts, with parts and any after-hours surcharge spelled out. Vague verbal estimates that balloon on the invoice are the number-one complaint in this trade.
3. Real fault-finding skill. A good electrician diagnoses why a circuit trips rather than just resetting the breaker and leaving. Ask how they approach fault finding; the answer tells you a lot.
4. Reviews at volume. A 5-star rating on five reviews means little. I trust a 4.7 to 4.9 average built on hundreds of reviews far more, because it shows consistency across many real jobs.
5. Warranty and a safety-first attitude. Reputable firms stand behind their work with a warranty and never cut corners on isolation, earthing, or testing. Safety shortcuts on electrical work are not worth any saving.

I built this shortlist by searching the way a homeowner would: best electrician Singapore, licensed electrician, LEW electrician, plus Reddit threads and Google reviews. I prioritised firms with a live website, EMA licensing or a clear licensed-engineer chain, a healthy volume of recent reviews, and transparent service and pricing pages. Where I could verify a Google rating or review count, I have noted it; where a figure was qualitative, I have described it that way rather than inventing a number.

No electrician paid for placement, and nobody sponsored this post. These are my honest editorial picks based on what is publicly verifiable in 2026. Ratings and review counts move over time, so treat them as a snapshot, and always confirm a current quote and the LEW arrangement directly with the company before you book.

Yes. Any work involving your HDB flat fixed wiring, a DB box change, or a power supply upgrade should be carried out or supervised by an EMA Licensed Electrical Worker, and most reputable firms describe themselves as HDB-approved for this reason. A general handyman can usually swap a like-for-like light fitting, but rewiring, new wiring runs, and consumer-unit changes are licensed work. You can check a worker on the EMA ELISE portal, and a trustworthy company will provide a LEW ID before starting.

A breaker that keeps tripping is doing its job, it is cutting power to protect you from a fault. The usual causes are an overloaded circuit (too many high-draw appliances on one line), a faulty appliance leaking current, water ingress into a socket or fitting, or aged and damaged wiring. A good electrician will isolate which circuit and which appliance is at fault rather than just resetting the switch, because repeated tripping on the same circuit almost always means there is a real problem to fix, not just a nuisance to reset.

Yes, and several firms on this list are built around it. AVV Electrical, Daylight, CWC, Competent Electrician, and Electrician24.sg all run 24/7 lines, with the emergency specialists promising arrival within roughly 30 minutes. Expect an after-hours call-out to cost more than a daytime visit, so for a non-urgent issue it is cheaper to book during office hours. For a genuine emergency like a total power loss, a burning smell, or sparking, call straight away and do not attempt the repair yourself.

A standard DB (distribution board) box change in an HDB flat or condo usually takes a licensed electrician about 3 to 5 hours, including isolating the supply, swapping the board and breakers, testing every circuit, and tidying up. Larger landed homes or jobs that involve upgrading capacity can run longer and may need additional scoping. Your power will be off for part of the work, so plan around it, and make sure the electrician tests and labels each circuit before signing off.
