A Clearer Approach to Residential Rewiring
Residential rewiring can involve several connected decisions, from circuit planning and DB protection to point locations and cable routing.
Our approach is to confirm the scope before installation and keep the finished electrical system organised and documented.
- Itemised quotation before work starts
- Clear circuit planning based on your home’s requirements
- Labelled DB schedule for easier future maintenance
- Testing and handover records after completion
- Singapore-based team available by phone or WhatsApp
What Our Clients Say About Our Work
Real reviews from homeowners and businesses, pulled from our Google Business Profile.
Rewiring for Different Types of Homes
The basic rewiring principles are similar, but property access, renovation requirements and electrical loads can differ significantly.
HDB Flats
From 3-room to 5-room flats, residential rewiring is often coordinated with renovation work, hacking permits and the planned location of sockets, lighting and appliances.
Condos and Apartments
Condominium rewiring may need to account for MCST requirements, permitted working hours, access restrictions and limitations on hacking or common areas.
Landed Houses
Multi-storey landed homes can involve longer cable runs, multiple distribution boards, outdoor circuits and larger electrical loads.
Full House Rewiring or Partial Rewiring?
The right option depends on the condition of the existing wiring and what you need the electrical installation to handle.
Full House Rewiring
The existing wiring throughout the agreed areas is replaced with new circuits and cabling. This is commonly considered for older installations, major renovations or properties where a large portion of the existing wiring needs replacement.
Partial Rewiring
Only selected circuits, rooms or areas are rewired while suitable existing wiring remains in place. This can be appropriate when the issue is limited to certain areas or when new circuits are needed for additional appliances.
| Comparison | Full rewiring | Partial rewiring |
|---|---|---|
| What is replaced | All agreed circuits and cabling | Selected circuits or areas |
| DB box | Usually replaced or upgraded | Upgraded if required |
| Best suited to | Older installations and major renovations | Specific areas, faults or upgrades |
| Disruption | Higher | Lower |
Not sure which option applies to your home? A site survey checks the existing installation before the scope is confirmed.
What Residential Rewiring Can Include
Every project is scoped after the site survey, but residential rewiring may include the following.
Wiring and Circuits
- New cabling for lighting, power and dedicated appliance circuits
- Concealed wiring inside walls and ceilings
- Surface trunking where concealed routing is not practical
- Additional sockets, switches and lighting points
- Separate circuits for air-conditioners, water heaters, ovens and induction hobs
Distribution Board and Protection
- New or upgraded DB box
- RCCB and MCB protection
- Circuit labelling and updated DB schedule
See our DB box upgrade and replacement service.
Electrical Loading
If your planned appliances require more capacity than the existing supply can provide, rewiring can be paired with an electrical loading upgrade.
Plan Rewiring Before the Renovation Is Finished
Renovation is often the most practical time to carry out rewiring because walls, ceilings and other areas may already be accessible.
Electrical points, appliance locations and cable routes can be planned before carpentry, false ceilings and finished surfaces are installed. This helps avoid reopening completed areas later.
If you’re working with an interior designer or renovation contractor, the electrical point layout and installation schedule can also be coordinated before work begins.
Our Residential Rewiring Process
From the first enquiry to testing and handover, every residential rewiring job follows the same five steps.
- Enquiry and Initial Details
Tell us your property type, approximate size, what is prompting the rewiring and whether renovation work is planned.
- Site Survey
We inspect the existing wiring, DB box, protection devices, electrical points and practical access.
- Scope and Quotation
We confirm full or partial rewiring, circuit requirements, wiring method and point locations before providing an itemised quotation.
- Installation
Old wiring is removed or isolated where required, and the new cables, circuits, DB work and electrical points are installed according to the agreed scope.
- Testing and Handover
The completed installation is tested, circuits are labelled and the relevant test records and handover information are provided.
For the complete six-step process, see our electrical rewiring services.
Residential Rewiring Cost in Singapore
Rewiring cost depends on the property size, full or partial scope, number of circuits and points, wiring method, DB box requirements and whether an electrical loading upgrade is needed.
There is no single price that applies to every home. For a figure based on your actual property, we’ll provide an itemised quotation after the site survey.
What affects your price
- Property size and number of rooms
- Full or partial rewiring scope
- Number of circuits and electrical points
- Concealed wiring or surface trunking
- DB box work and any loading upgrade
Testing and Electrical Compliance
Residential rewiring should be tested before the completed installation is put into use. Depending on the project, this can include insulation resistance, earth continuity and RCCB testing, together with circuit labelling and handover documentation.
Where required, a Licensed Electrical Worker (LEW) coordinates the relevant testing, endorsement and submissions.
For more information, see our electrical testing, inspection and compliance support.
Residential Rewiring Questions We Often Get
How do I know if my home needs rewiring?
Frequent tripping, warm or damaged sockets, burning smells, outdated wiring or plans to add several high-load appliances can be reasons to have the electrical installation checked. A site survey can determine whether partial or full rewiring is appropriate.
Does an older home always need full rewiring?
Not necessarily. The required scope depends on the condition of the existing wiring, the electrical loads and what you plan to change. Some homes may only need selected circuits replaced, while others may require a more extensive rewire.
Can I stay in the home while rewiring is being done?
For partial rewiring, it may be possible to remain in the property with power interruptions limited to the affected areas. Full rewiring generally causes more disruption and is often easier to schedule during renovation or before moving in.
Should rewiring be done before renovation?
Ideally, yes. Wiring runs behind walls and ceilings, so completing the electrical work before carpentry, false ceilings and finished surfaces can help avoid reopening completed areas.
Do I need to replace the DB box when rewiring?
For a full rewire, the DB box may be replaced or upgraded so the new circuits have suitable protection. For partial rewiring, the existing board is assessed based on its condition, capacity and protection.
How much does residential rewiring cost in Singapore?
The cost depends on the property, rewiring scope, number of circuits and points, wiring method, DB work and other electrical requirements. An itemised quotation after a site survey gives a more accurate figure for your home.
