How much does an electrician cost in Singapore? A transparent breakdown
Electrical pricing in Singapore is all over the place. Here's a transparent breakdown of typical jobs — from a $40 socket swap to a $1,200 DB upgrade — and what to ask when a quote feels off.
SparkFlow team6 min readFinding out what an electrician should actually cost in Singapore is harder than it should be. Some quotes will surprise you in a good way; others double mid-job. This is our honest breakdown of the going rates for the most common electrical jobs in 2026 — and what red flags to watch for.
What you're actually paying for
Three things bundled into every electrician's quote:
- Callout / minimum visit fee — covers travel, diagnosis, and a baseline of work
- Labour time — usually quoted as a flat job rate, sometimes by the hour for diagnostics
- Parts — sockets, breakers, wiring, fittings; ranges from $5 (a basic switch) to $300+ (RCBOs, premium light fixtures)
Typical job pricing
| Job | Typical price |
|---|---|
| Single socket / switch replacement | $40–$80 |
| Light fixture installation | $40–$120 |
| Power point addition (existing circuit) | $80–$180 |
| Dedicated circuit (oven, water heater, EV charger) | $200–$450 |
| Power tripping diagnostic | $40 callout, $80–$200 to fix |
| Ceiling fan installation | $80–$180 |
| Water heater electrical (dedicated point) | $150–$300 |
| DB box upgrade | $400–$1,200 |
| Full HDB rewiring | $2,500–$6,000 |
Single socket / switch replacement — $40–$80
Like-for-like replacement of a faulty 13A socket or light switch. Usually 20–30 minutes on site. Price includes the new fitting if standard.
Light fixture installation — $40–$120
Hanging a new pendant, replacing a downlight, fitting a fan with light. Higher end if drilling new mounting points or working with false ceilings.
Power point addition (new socket on existing circuit) — $80–$180
Tapping into an existing circuit to add a new socket nearby. Includes some wall chasing if neat finish is required.
Dedicated circuit (e.g. for oven, water heater, EV charger) — $200–$450
New cable run from DB box to a new outlet, new MCB in the DB. Price scales with cable length and complexity (false ceiling work, drilling through concrete, etc).
Power tripping diagnostic — $40 callout, $80–$200 to fix
$40 is the diagnosis fee. The fix cost depends entirely on what we find — a faulty appliance is free (just unplug it), a damaged socket is $60, a failing MCB is $80, a wet circuit needing isolation is $150+. If your breaker keeps cutting out, our power-trip diagnosis service traces the exact fault, and our guide to the most common HDB power-tripping causes explains what usually triggers it.
Ceiling fan installation — $80–$180
Like-for-like swap is $80. If we need to install a new fan box, run wiring for a wall control, or wire a 4-speed regulator with a downrod, expect higher. See our ceiling fan installation service for the full scope.
Water heater electrical (dedicated point) — $150–$300
Dedicated 13A or 20A circuit from DB to water heater location. Higher end if a 20A circuit is required and wiring needs to run through false ceilings. This is the electrical groundwork behind a water heater replacement, so it's worth sorting the circuit at the same time as the unit.
DB box upgrade — $400–$1,200
Replacing the entire distribution board with modern MCBs and RCBO protection, which is the heart of any rewiring and upgrade job. Price depends on number of circuits. Most 4 and 5-room HDBs land in the $550–$800 range. Our HDB DB box upgrade guide walks through when a swap is actually worth it.
Full HDB rewiring — $2,500–$6,000
Replacing every cable in the flat. Major job, almost only done during a resale flat renovation. Includes new sockets, new switches, new lighting points, new DB box.
What changes the price
- After hours / weekend work — usually +30–50%
- Same-day emergency — premium on diagnosis fee (~$60–$80 vs $40)
- False ceiling work — adds time, sometimes adds an assistant
- Concrete drilling through structural walls — additional labour + special drill bits
- Brand/quality of parts — premium sockets (e.g. Schneider, MK) cost more than budget
- Working at height — scaffolding adds cost on landed homes
What to watch out for
"Free diagnosis" quotes that feel too cheap
Genuinely free diagnosis usually means the diagnosis isn't thorough — they'll guess at the problem so they can quote a fix. Better to pay $40 for a proper diagnostic and get accurate information.
Vague hourly rates without job estimates
"We charge $40/hour" with no estimate of total hours is how 1-hour jobs turn into 4-hour invoices. Ask for a fixed-price quote on the scope before the work starts.
Wildly low quotes
A $200 DB box upgrade isn't possible if you're using proper RCBO breakers and a Licensed Electrical Worker. Something is being cut — corners, licensing, or parts quality.
No LEW number on the invoice
For HDB electrical work, the Licensed Electrical Worker (LEW) number should appear on quote or invoice — every job booked through our licensed electrical service is covered by one. Anyone refusing to give it isn't licensed, which voids your home insurance.
How we price
Our pricing philosophy: your quote is your quote. Once we've seen the job and given you a number, we don't change it mid-work unless we find something genuinely unforeseen — and even then, we'll always stop and confirm before continuing.
Photos and a brief description on WhatsApp are usually enough for us to ballpark within 10%. On-site we'll confirm before we start.
The takeaway
Most common electrical jobs in Singapore land between $40 and $300. Anything outside that range is either suspiciously cheap (cut corners) or a major job that deserves a proper site visit before quoting.
Knowing the rough ranges puts you in a much better negotiating position. Hopefully this saves you from a surprise invoice or two.
Frequently asked questions
- How much does an electrician cost in Singapore?
- Most common electrical jobs land between $40 and $300. A single socket or switch swap runs $40–$80, a power point addition $80–$180, and a power-tripping diagnostic is a $40 callout with $80–$200 to fix. Bigger jobs like a DB box upgrade cost more.
- How much is a power trip diagnosis in Singapore?
- The diagnosis fee is $40. The fix then depends on the fault: a faulty appliance is free (just unplug it), a damaged socket is $60, a failing MCB is $80, and a wet circuit needing isolation is $150 or more. Same-day emergency callouts run about $60–$80.
- How much does a DB box upgrade cost in an HDB flat?
- A full distribution board upgrade with modern MCBs and RCBO protection costs $400–$1,200, depending on the number of circuits. Most 4 and 5-room HDB flats land in the $550–$800 range. A $200 DB upgrade isn't realistic with proper RCBOs and a Licensed Electrical Worker.
- Do I need a licensed electrician for HDB electrical work?
- Yes. For HDB electrical work, a Licensed Electrical Worker (LEW) number should appear on your quote or invoice. Anyone refusing to provide it isn't licensed, which can void your home insurance. Always check the LEW number before any work begins.
- Why do electrician quotes in Singapore vary so much?
- Quotes shift with after-hours or weekend work (usually +30–50%), same-day emergency premiums, false-ceiling or concrete-drilling labour, part quality, and working at height. Wildly low quotes usually mean corners, licensing, or parts quality are being cut, so they're worth questioning.
