What "Complete Residential Rewiring" Means
Knowing the difference between a full rewire, a partial rewire and a repair helps you compare quotes properly.
Complete rewire
Full replacement of every cable, socket, switch, light point and the DB box, bringing the entire installation up to Singapore Standard CP5, with proper earthing, RCD protection and a LEW-signed Certificate of Compliance.
Partial rewire or repair
One room, the kitchen or the water-heater circuit, or a single damaged section. See Electrical Wiring Repair. For when a full rewire is the right answer, see the Electrical Rewiring Singapore hub.
Condominiums
Condominium Rewiring (MCST Approval Process)
Technically similar to an HDB rewire, but the rules on access, working hours and approval are very different. Every condo has its own MCST requirements, and we handle that side for you.
- MCST submissionThe electrical scope, contractor credentials and work schedule.
- Working hours complianceMost MCSTs allow electrical work 9 am to 5 pm on weekdays, with limited weekend access.
- Common property accessCorridors, refuse rooms and electrical risers, coordinated with the Managing Agent.
- Materials and noise restrictionsSome MCSTs restrict wall chasing, certain adhesives or after-hours work.
- Final MCST sign-offOur LEW endorsement and CoC are typically what the MCST wants to see.
HDB Flat Over 20 Years Old, Renovating or Selling?
A full rewire is the right next step, and it starts with a free site survey: we look at the actual condition of your installation and give you a fixed written quote.
Every property type
Landed, Concealed & Renovation Rewiring
Different homes need different approaches. These are the rewiring projects we handle most often beyond a standard HDB flat.
Scenario 01
Landed Property Rewiring
A different scale: more circuits, longer cable runs, more labour and more flexibility in how the install is done.
- Older landed houses (pre-1990s) with original rubber-insulated cable: usually a full rewire is the only safe answer.
- Houses being renovated: the rewire is coordinated with the ID, with false ceiling, floor screed and hacking scheduled around the electrical rough-in.
- Houses with additions such as a pool, gate motor, garage EV charger or workshop, which need properly sized new circuits and often a DB upgrade.
- Smart home wiring: the right time to add a neutral to every switch box and run Cat 6. See Smart Switch & Smart Home Installation.
Landed rewires typically take 2–4 weeks and run $18,000–$35,000+ depending on size and scope.

Scenario 02
Concealed Wiring for HDB & Condo
Cables run inside the wall, ceiling or floor: the standard for any serious HDB or condo rewire. Invisible once plastered, no surface trunking and higher resale value. The trade-off is more labour and careful planning.
Most HDB flats built before 2010 have concealed wiring that is now 15–25 years old. The most common cable in pre-2000 HDB is PY cable, which turns brittle with age. A full rewire replaces it with modern PVC-insulated cable, properly rated and earthed.
Hacking walls for a renovation? Rewire at the same time: opening the wall twice is expensive. For a single damaged section, see Electrical Wiring Repair.

Scenario 03
HDB Renovation Electrical Works (with DB Box Upgrade)
A rewire and a DB upgrade go together. Replacing the cables without the DB leaves you with the same circuit count, main breaker and RCCB arrangement. Our standard HDB renovation package includes:
- New 16-way or 24-way DB box (see DB Box Electrician)
- Main RCCB and sub-RCBOs, including HDB 2nd RCCB compliance
- MCBs and RCBOs for new aircon, water heater, smart switch or EV circuits
- Concealed cable rewire for every room, to current standard
- New switches, sockets and lighting points per the renovation drawing
- LEW endorsement + CoC and HDB renovation guideline compliance
We coordinate with your ID for rough-in, the DB upgrade, new socket and fan points and the final trim-out: usually 3–5 site visits across the renovation.

Residential Rewiring FAQs
Straight answers about timing, staying at home, HDB, property value, partial rewires and resale paperwork.
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; we tell you upfront which makes sense.
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?
For older HDB and resale condos, a recent rewire with a CoC is a strong selling point. Buyers, banks and lawyers all look for it.
Can I rewire only part of the flat?
Yes. A partial rewire (1–2 rooms, the kitchen or the water-heater circuit) is a sensible option when the rest of the installation is sound. See our Electrical Wiring Repair page.
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.
