Electrical Works Cost in Singapore: What You'll Actually Pay (2026)

Prices checked October 2026 against the published price lists of 526 contractors listed on Homees, MOM's 2025 wage data and Qanvast's 2026 report. How we price →

Electrical work is priced two ways: **per point** for adding or moving sockets and lights, and as a **lump sum** for bigger jobs like a full rewire or a new DB box. For a typical HDB renovation it usually lands at **10–15% of your total reno budget** — roughly **S$2,000–S$5,500** for a 3- to 4-room flat, more if you're rewiring or going concealed.

One non-negotiable first: in Singapore, all electrical work must be done by a Licensed Electrical Worker (LEW). This isn't the corner to cut.

Here's what the common jobs cost.

Job	Typical cost	Notes
Light point (wiring + switch)	S$30 – S$55	Fixture install is usually extra
Power socket — single	S$40 – S$100	Surface; concealed costs more
Power socket — double	S$60 – S$100
Fan / heater point	S$60 – S$120	Higher load
Aircon isolator	S$120 – S$180	One per aircon unit
DB box / distribution board upgrade	S$350 – S$1,200+	Depends on breakers + testing
Full rewire (4-room HDB)	S$3,000 – S$5,500	Older flats with aged cables

Indicative 2026 ranges. Final price depends on point count, surface vs concealed wiring, and your flat's condition.

The per-point price list

Most renovation electrical is quoted point by point. Standard residential rates:

Item	Cost (per point)
Light point (incl. wiring & switch)	S$30 – S$55
Light fixture install (if separate)	S$10 – S$20
Power socket — single	S$40 – S$100
Power socket — double	S$60 – S$100
Weatherproof / outdoor socket	S$80 – S$120
Fan / heater point	S$60 – S$120
Aircon isolator	S$120 – S$180
Data / network point	S$40 – S$80
Standalone switch	S$40 – S$75
Heavy-duty 15A socket	S$100 – S$200

One thing that trips people up: in a new BTO, the wiring and switches are already there, so you might only pay for fixture installation (S$10–S$20 a light). In a resale flat you often pay for the full point — wiring plus install.

Surface vs concealed wiring — the real cost driver

This is the choice that moves your bill the most.

Surface (trunking) wiring runs along the wall in casing. It's faster, cheaper, and easy to modify later — common in resale flats and budget jobs.

Concealed wiring is buried inside the wall. It looks clean and is what most renovations go for, but it means chasing the walls, hacking and re-plastering — so labour and reinstatement push the cost up, usually 10–15% more than the equivalent surface job, sometimes more in private property.

If budget's tight and looks aren't everything, surface wiring in the right spots saves real money.

Rewiring and DB box

Older flats sometimes need more than new points:

Full rewire: roughly S$1,200–S$5,000 for a 3-room and S$3,000–S$5,500 for a 4-room, depending on point count and surface vs concealed. A 5-room or executive runs S$4,000–S$7,000. Condos and landed often exceed S$8,000–S$15,000.
DB box / distribution board upgrade: S$350–S$1,200+, depending on board size, number of breakers and testing.
Circuit breaker replacement: S$100–S$250 per unit.

If your circuits trip often, lights flicker, or the DB smells burnt — that's the sign it's time. Adding high-load appliances (instant heaters, ovens, multiple aircon units) can also force a DB upgrade.

Whole-flat electrical, by size

For a full renovation — all light points, power points, switches, DB upgrade and labour:

Flat	Complete electrical (est.)
3-room HDB	S$2,000 – S$4,000
4-room HDB	S$3,000 – S$5,500
5-room / executive	S$4,000 – S$7,000
Condo / landed	S$8,000 – S$15,000+

The costs people forget

Hacking & patching for concealed wiring — baked into that 10–15% concealed premium, but make sure it's in the quote.
Main supply cable upgrade — older flats adding heavy loads may need a thicker incoming cable.
Rewiring aged cables — if the existing wiring is old or unsafe, replacing it isn't optional.
Light fixtures themselves — point pricing usually covers wiring and install, not the lamp you're buying.
After-hours / urgent call-outs — troubleshooting visits run S$50–S$90+, more outside normal hours.

Rules worth knowing

LEW is mandatory. All electrical work must be done by a Licensed Electrical Worker under the Electricity Act — for safety and insurance, don't use an unlicensed handyman.
Bathrooms: follow HDB rules on heater placement; isolators and switches stay outside the wet area.
Condos: some MCST require approval before adding high-load points on balconies or yards.
Brands matter. Approved brands (Schneider, Hager, Legrand, MK, Honeywell) cost a little more but are worth it on safety-critical parts.

How to keep the bill sensible

Plan all your points upfront. Adding points after the walls are sealed means hacking again — expensive. Walk the layout and mark every socket and light before works start.
Use surface wiring where it won't be seen (store room, service yard) to save on concealment.
Don't over-socket. It's easy to add 30 points "just in case". Put them where you'll actually use them.
Bundle the electrical with your main reno so it's coordinated with the carpentry and not retrofitted later.

FAQ

How much does electrical work cost in Singapore? Per point, expect S$30–S$55 for a light point, S$40–S$100 for a power socket, and S$120–S$180 for an aircon isolator. A complete HDB job runs about S$2,000–S$5,500 depending on flat size, and a full rewire S$3,000–S$5,500 for a 4-room.

How much to add a power point? A single power socket is about S$40–S$100, a double S$60–S$100. Weatherproof and heavy-duty sockets cost more. Concealed wiring adds roughly 10–15%.

How much does it cost to rewire an HDB flat? Roughly S$1,200–S$5,000 for a 3-room and S$3,000–S$5,500 for a 4-room, depending on point count and whether the wiring is surface or concealed. Condos and landed homes can exceed S$8,000.

What's the difference between surface and concealed wiring? Surface wiring runs in trunking on the wall — cheaper and faster. Concealed wiring is hidden inside the wall — neater, but needs hacking and re-plastering, so it costs about 10–15% more.

How much is a DB box upgrade? A distribution board upgrade is about S$350–S$1,200+, depending on board size, breakers and testing. A single circuit breaker replacement is S$100–S$250.

Do I need a licensed electrician in Singapore? Yes. All electrical work must be carried out by a Licensed Electrical Worker (LEW) under the Electricity Act. Don't use an unlicensed handyman for wiring.

When should I rewire my flat? If your circuits trip often, lights flicker, the DB smells burnt, or you're adding high-load appliances to an older flat with aged cables — those are the signs to rewire.
