Residential Rewiring Singapore | HDB, Condo & Landed

If you are looking at a full rewire of your home, you are probably at one of three points: a renovation is coming and the existing wiring is past its time; you are buying or selling an HDB flat and the buyer’s lawyer or bank is asking for a recent CoC; or you have just had a scare — a burnt socket, a tripped breaker that will not stay, a faint burning smell — and you want the whole installation checked, not just the one fault.

TRUST ELECTRICIANS specialises in complete residential rewiring across Singapore. HDB flats, condominiums, landed houses — we do it every week, with the same LEW-endorsed, CoC-issued, fixed-quote discipline regardless of property type.

What "Complete Residential Rewiring" Means

A complete residential rewire, in our definition, is the full replacement of every cable, every socket, every switch, every light point, and the DB box — bringing the entire installation up to current Singapore Standard CP5, with proper earthing, RCD protection, and a LEW-signed Certificate of Compliance.

It is not the same as a partial rewire (one room, the kitchen, or the water-heater circuit) or a repair. For a partial rewire, see our Electrical Wiring Repair page. For the broader context of when a rewire is the right answer, see our Electrical Rewiring Singapore page — the umbrella hub for all rewiring work.

HDB Flat Rewiring (3-Room / 4-Room / 5-Room / EA)

The bread and butter of our residential rewiring work. Each HDB flat type has its own typical scope:

3-room HDB (≈ 65 sqm): 1 bedroom, 1 common bedroom, 1 bathroom, kitchen, living. Typical scope: 8–12 way DB, 20–25 socket points, 8–12 lighting points, 1 cooker point, 1 water heater point. Typical rewire time: 5–7 working days.
4-room HDB (≈ 90 sqm): 2 bedrooms, 2 bathrooms, kitchen, living, dining. Typical scope: 12–16 way DB, 30–40 socket points, 12–18 lighting points, 1 cooker point, 2 water heater points. Typical rewire time: 7–10 working days.
5-room / Executive HDB (≈ 110–130 sqm): 3 bedrooms, 2 bathrooms, kitchen, living, dining, store. Typical scope: 16–20 way DB, 35–50 socket points, 15–25 lighting points, 1 cooker point, 2–3 water heater points, often a study or utility room. Typical rewire time: 8–12 working days.

For HDB-specific issues that often come up during a rewire — the 2nd RCCB rule, the HDB electrical loading, the HDB renovation guidelines — see our HDB Electrician Singapore page.

Condominium Rewiring (MCST Approval Process)

A condo rewire is technically similar to an HDB rewire, but the rules around access, working hours, and approval are very different. Every condo is governed by an MCST, and they each have their own requirements.

What we handle for the MCST side:

MCST submission of the electrical scope, the contractor’s credentials, and the work schedule
Working hours compliance — most MCSTs allow electrical work only 9 am – 5 pm weekdays, with limited weekend access
Common property access — corridors, refuse rooms, electrical risers, all coordinated with the Managing Agent
Materials and noise restrictions — some MCSTs restrict chasing walls, certain adhesives, or after-hours work
Final MCST sign-off — the LEW endorsement and CoC we provide is typically what the MCST wants to see

The MCST approval typically takes 1–2 weeks if the scope is well documented. We help you prepare the submission so it goes through on the first try.

For the broader condo property-type context, see our Commercial Electrician Singapore page (which covers condo commercial units) and our HDB Electrician Singapore page (which covers the residential condo and HDB side).

Landed Property Rewiring

Landed house rewiring is a different scale of work. More circuits, longer cable runs, more labour, and more flexibility in how the install is done.

Common landed scenarios:

Older landed houses (pre-1990s) with original rubber-insulated cable — usually a full rewire is the only safe answer. See our Electrical Rewiring Singapore page for the signs that a rewire is overdue.
Landed houses being renovated — the rewire happens during the renovation, coordinated with the ID. False ceiling work, floor screed work, and any wall hacking are scheduled around the electrical rough-in.
Landed houses with additions — pool, gate motor, garage EV charger, home workshop, larger air-conditioning. These often trigger a 3-phase supply upgrade — see our 3-Phase Power Installation page.
Landed houses with smart home wiring — the rewire is the right time to add neutral to every switch box, run Cat 6 data points, and plan the smart-home hub location. See our Smart Switch & Smart Home Installation page.

Landed rewires typically take 2–4 weeks and run $18,000 – $35,000+ depending on size and scope. See our Electrical Services Price List for current rates.

Concealed Wiring for HDB & Condo

Concealed wiring — cables run inside the wall, ceiling, or floor — is the standard for any serious HDB or condo rewire. The benefits are real: invisible once plastered, no surface trunking to look at, higher resale value. The trade-off is that it is more labour-intensive and the cable runs have to be planned carefully.

The HDB-specific context is important: most HDB flats built before 2010 have concealed wiring that is now 15–25 years old. The most common cable type in pre-2000 HDB is PY cable (rubber-insulated), which becomes brittle with age. A full rewire replaces PY cable with modern PVC-insulated cable, properly rated for the load, with proper earthing.

If you are doing a renovation that involves hacking walls, the rewire is the right time to do it — opening the wall twice is expensive. For the concealed-wiring repair side (a single damaged section rather than a full rewire), see our Electrical Wiring Repair page.

HDB Renovation Electrical Works (with DB Box Upgrade)

A typical HDB BTO or resale renovation involves both an electrical rewire and a DB box upgrade. The two go together — replacing the cables without upgrading the DB box leaves you with the same old circuit count, the same old main breaker, and the same old RCCB arrangement.

Our standard HDB renovation electrical package includes:

New 16-way or 24-way DB box — see our DB Box Electrician Singapore page for the DB-side detail
Main RCCB and sub-RCBOs — including the HDB 2nd RCCB compliance for socket and water-heater circuits. See our ELCB / RCCB Installation page.
MCB and RCBO additions for any new circuits — aircon, water heater, smart switch, EV charger
Concealed cable rewire for every room, brought up to current Singapore Standard
New switches, sockets, and lighting points as per the renovation drawing
LEW endorsement + CoC for the full rewire
HDB renovation guideline compliance throughout

We coordinate with your ID for the electrical rough-in, the DB upgrade, the new socket and fan points, and the final trim-out. For an HDB BTO or resale renovation, we are usually on site 3–5 times across the renovation timeline.

Residential Rewiring Cost & Packages

Transparent, fixed pricing. Full current rates on our Electrical Services Price List Singapore page. As a guide for 2025–2026:

Property Type	Typical Price (SGD, full rewire)
3-room HDB	$3,800 – $6,500
4-room HDB	$4,800 – $7,800
5-room / Executive HDB	$5,800 – $9,500
Condo (1,000 – 1,400 sqft)	$7,500 – $14,000
Landed (intermediate terrace)	$18,000 – $35,000
Partial rewire (1–2 rooms)	$1,800 – $4,500

What affects the price:

Property type and size — HDB cheapest, landed most expensive
Concealed vs surface wiring — concealed adds labour
Existing wiring condition — old PY cable that crumbles adds time
DB box replacement — almost always part of a rewire, adds $850 – $2,200
HDB 2nd RCCB compliance — required since 2024, adds $320 – $520
Renovation coordination — we work with your ID to reduce double-work

You receive a fixed written quote after the free site survey, with no “we’ll see” clauses.

Our Rewiring Process

The full process, in seven steps:

Free site survey — we visit, inspect the existing installation, count circuits, check the DB, and discuss what you actually need. 1–2 hours.
Detailed written quote — itemised by room, by circuit, by component. Within 1–2 working days.
Pre-rewire LEW inspection (if required for HDB resale, MCST, or insurance)
Rewire works — hack and chase, pull new cables, install new DB, reconnect every circuit, make good
LEW inspection, testing, and endorsement — insulation resistance, earth continuity, polarity, RCD trip time, earth loop impedance
LEW-signed Certificate of Compliance (CoC) — for the full rewire
Handover and aftercare — we walk you through the new DB, label every circuit, and provide a 14-day workmanship warranty

FAQs

How long does a residential rewire take?

A 4-room or 5-room HDB typically takes 5–12 working days, depending on the scope. A condo takes 1–3 weeks. A landed house takes 2–4 weeks. The actual power-off time during the DB swap is usually 4–6 hours.

Do I need to move out during the rewire?

For most HDB and condo rewires, no. We work room by room and keep at least one circuit (lighting, fridge, one socket) live at all times. For a full landed rewire, some homeowners choose to move out for the duration; we will tell you upfront which it makes sense for.

Is a rewire covered by HDB?

No. Internal rewiring is the homeowner’s responsibility. HDB only owns and maintains the building infrastructure up to your DB.

Will a rewire increase my property value?

Yes — for older HDB and resale condos, a recent rewire with CoC is a strong selling point. Buyers, banks, and lawyers all look for it.

Yes. A partial rewire (1–2 rooms, the kitchen, or the water-heater circuit) is a common and sensible option when the rest of the installation is sound. See our Electrical Wiring Repair page for the smaller-scale scope.

Do you handle HDB resale handover paperwork?

Yes — we coordinate with HDB, your ID, and your lawyer for the electrical side of the resale handover. See our Electrical Inspection, Testing & Maintenance page for the pre-handover LEW inspection.

Planning a Residential Rewire? Let's Start with a Free Site Survey.

If your HDB flat is more than 20 years old, you are renovating, you are preparing for resale, or you have had any of the warning signs — a full rewire is the right next step. The first step is a free site survey, where we look at the actual condition of your installation and give you a fixed written quote.
