HDB electrical works: power points, LED lighting & rewiring costs

Wondering what it costs to add a power point in an HDB flat? Budget around S$80–150 per point, with LED downlights at about S$40–80 per point to install and data points at S$100–150 each. For whole-flat HDB electrical works during a renovation, a realistic 2026 figure is in the S$4,000–6,000 range — a recent RK E&C project in Bukit Panjang came to about S$4,800 plus S$850 of add-ons, and we break that down below. This guide covers every common electrical job, what drives the price, and the one licensing rule you should never let a contractor skip.

What counts as "electrical works" in an HDB flat

Most electrical jobs in an HDB renovation fall into five buckets:

• Power points and switches — adding new 13A sockets, moving existing ones, converting single to double gang, adding two-way switching for bedrooms and hallways.
• Lighting points — LED downlights, cove/strip lighting, pendant points, and relocating ceiling points to suit a new layout.
• Data and LAN points — wired Cat6 runs from the fibre termination point to the TV console or a work desk.
• Heavy appliances — dedicated circuits for water heaters, ovens, induction hobs and some aircon systems.
• Rewiring and distribution board work — replacing ageing cables and upgrading the DB, mainly relevant to older resale flats.

The first three are what most owners actually buy, so let's put real numbers on them.

HDB electrical works cost: real numbers from a recent project

Generic price lists are easy to find and easy to distrust. Here's an anchor from an actual job instead: a recent RK E&C whole-flat project in Bukit Panjang, where we did the full electrical package as part of a larger renovation.

Item	Cost (SGD)	Notes
Full-home electrical package (Bukit Panjang project)	≈ $4,800	LED lights, data point, Schneider switches & power points throughout; light fittings & fans supplied by owner
Additional electrical works (same project)	≈ $850	Extra points and changes added mid-renovation
Add a power point	$80 – $150 each	Cheaper per point when bundled or concealed during reno
Install LED downlight	$40 – $80 per point	Labour only; lowest cost when done with false ceiling works
Data / LAN point	$100 – $150 each	Cat6 run back to router or fibre termination point

Two things worth noting from that project. First, the owner supplied their own light fittings and ceiling fans — the S$4,800 covered wiring, points, installation and Schneider switches and sockets. Second, the S$850 of "additional works" is typical: once walls are open, most owners realise they want a few more points, and adding them mid-job is far cheaper than after handover.

Adding power points and switches

The S$80–150 range per point moves on three factors:

• Concealed vs surface wiring. During a renovation, cables run inside walls before plastering, so the finish is clean and the per-point cost is low. After renovation, the same point either needs surface trunking (cheaper, visible) or hacking and patching (tidier, pricier).
• Distance from the nearest circuit. A point beside an existing run costs less than one across the room.
• Quantity. Ten points in one visit cost much less per point than one point per visit.

On hardware: we default to Schneider switches and sockets on our projects. The price gap versus no-name fittings is a few dollars a point, and it buys you consistent build quality, proper safety certification and parts that are still purchasable when you want to add a matching point five years on.

LED downlights and cove lighting

Downlights and cove strips are the reason most living rooms get a false ceiling at all. The install labour is modest — about S$40–80 per downlight point — but the sequencing matters more than the price: wiring must be run and positions fixed before the ceiling boards close up. Retrofitting a downlight into a finished ceiling means cutting, fishing cables blind and patching paint.

If you're planning the ceiling and lighting together, our guide to false ceilings and cove lighting in HDB flats covers the carpentry side — L-box vs full false ceiling, and what each costs.

Practical tips that save money and regret:

• Choose colour temperature once, flat-wide (3000K warm or 4000K cool white) — mixed temperatures across rooms always shows.
• Put living room downlights on two or three switch groups so you're not stuck with all-on or all-off.
• Cove strips should be a known brand with a proper LED driver — cheap strips yellow and flicker within a couple of years, and replacing them means going back into the cove.

Data and LAN points

Wi-Fi through HDB concrete walls is mediocre, and mesh nodes only paper over it. A wired Cat6 data point costs about S$100–150 installed, and the two places it earns its keep are behind the TV console and at any work-from-home desk. Like lighting, LAN runs are dramatically easier while walls and ceilings are open — during our Bukit Panjang job the data point was simply part of the package, wired alongside the power runs.

When does an old flat need full rewiring?

Flats from the 1980s and earlier — and plenty of 1990s ones — often still carry their original wiring. Age shows up as brittle insulation, undersized circuits for modern loads, and a distribution board with no residual current protection by today's standards. Watch for:

• Breakers that trip repeatedly when the kettle, aircon and washing machine run together
• Warm or discoloured switch plates and socket faces
• Old two-pin sockets, or a shortage of points that has bred a jungle of extension cords
• A burning smell near any point — stop using it and get it inspected

Full rewiring is a bigger line item — it scales with flat size and how much of the wall and ceiling has to be opened — which is exactly why it should be decided at renovation time, not after.

Why a Licensed Electrical Worker (LEW) is non-negotiable

In Singapore, electrical installation work — new wiring, new circuits, alterations at the consumer unit — must be carried out or supervised by a Licensed Electrical Worker (LEW) under the Energy Market Authority (EMA) licensing framework. This isn't paperwork for its own sake: the LEW is the person professionally accountable for the installation being safe and up to code.

What this means for you as an owner:

• Anything beyond a simple like-for-like swap (replacing a faceplate, changing a light fitting on an existing point) should involve a LEW.
• A proper contractor prices the LEW into the quote as standard. If a quote is suspiciously cheap and vague about licensing, that's usually where the corner was cut.
• Unlicensed wiring isn't just an EMA compliance risk — it's a fire and shock risk hidden inside your walls, and it can complicate insurance claims later.

Where electrical fits in the renovation sequence

Electrical is a "first in, last out" trade. On a typical HDB renovation the order runs:

1. Hacking and masonry — walls and floors opened up.
2. First-fix electrical — conduits and cables run in walls and ceilings, point positions fixed. This must be finalised before plastering and before the false ceiling closes up.
3. Plastering, ceiling boards, tiling, carpentry, painting.
4. Second-fix electrical — switches, sockets, downlights and fans installed onto the finished surfaces, then tested.

The practical takeaway: walk the flat with your contractor before plastering and confirm every point position against your furniture plan — where the bed goes, which side of the sofa, where the router lives. Moving a point at that stage costs minutes; moving it after painting costs real money.

FAQ: HDB electrical works cost

How much does it cost to add a power point in an HDB flat?

Typically S$80–150 per point, depending on wiring distance, concealed versus surface trunking, and how many points are done in one visit. Concealed points added during a renovation are the cheapest per point.

How much does it cost to install LED downlights?

Installation labour runs about S$40–80 per point, on top of the fitting itself. The cost is lowest when downlights are wired together with false ceiling works, before the boards close up.

How much does full-flat electrical work cost during a renovation?

As a real anchor: a recent RK E&C whole-flat project in Bukit Panjang came to about S$4,800 for the full-home package — LED lights, a data point, Schneider switches and power points throughout (fittings and fans supplied by the owner) — plus about S$850 of additional works added mid-job.

Do I need a Licensed Electrical Worker (LEW)?

Yes, for anything beyond simple like-for-like swaps. Under EMA's framework, new wiring, new circuits and consumer-unit alterations must be done or supervised by a LEW. A reputable contractor includes this as standard.

When does an HDB flat need full rewiring?

Mostly older resale flats — roughly 30 years and up — showing tripping breakers, warm switch plates, two-pin sockets or blackened points. If you're already renovating, rewire then; opening finished walls later costs far more.

How much does a data or LAN point cost?

About S$100–150 per point for a Cat6 run back to your router or fibre termination point. One behind the TV and one at the work desk is the combination most owners end up glad they added.
