He also fixed for me water heaters, fans, data points etc.Well done Mr Masud. TqvmPosted on Google Michelle WangTrustindex verifies that the original source of the review is Google. As a first timer doing renovation, I was extremely careful in selecting which company to engage to do my house renovation. I was skeptical with all reno firms as I heard alot lf horror stories. But my initial gut feel tells me Bestvolt can be trusted & I was right! When I bought my resale flat which was in super bad state, I wasnt confident that anyone including Bestvolt can do much magic but I was proven wrong! Prior to engaging them, I have enquired over 20+ reno companies and I was very glad that I have chosen BestVolt in the end! Best choice I made for Year 2026! Haha. From plastering to electrical rewiring to painting, Bestvolt workers did an extremely good job, their workers were all skilled & know what they are doing & the end results is so good that I went WOW! Kudos to the person who replied my whatsapp queries, he was super patience (as It was my first time doing reno), I asked tons of questions but their patience is mainly what made me decided to engage them. Before engaging Bestvolt, in fact I have dropped another reno firm because their staff wasnt patience enough. I dont have an ID to save cost hence alot of things I dont know but Bestvolt explained everything to me in details. I also did compared over 20+ quotes and Bestvolt prices are very very reasonable. The workers were very fast in completing all the tasks & they were all very easy going despite me being fussy at certain point. I have since introduced Bestvolt to my friends & will continue to do so. I even told my friends if 5 years later I buy house again & want to reno, I will definately engage Bestvolt again!!!Posted on Google Divya GavaneTrustindex verifies that the original source of the review is Google. It was quick hassle free service and in very reasonable price.Posted on Google Uchiha NykeTrustindex verifies that the original source of the review is Google. service is very good and patient. price very reasonable 100% recommend the teamPosted on Google RayTrustindex verifies that the original source of the review is Google.

Fast and efficient changing of light bulb socket and installation of new PowerPoints. Thank you so much Best Volt. All of it took only 3 hours to change the whole house 14 power points! Would do so again.Posted on Google Julian ChangTrustindex verifies that the original source of the review is Google. Really great service alam and Jaman came down to my house for free quote and gave great advice. Conceal wiring, got me USB c plate, aluminum rail and install light steip. They made my vision come to life even though other contractors were apprehensive. They also helped to advise painters to cover up the work. 💯 Would recommend.
For Older and Renovating Homes in Yishun
Yishun is an established HDB town, with its first flats developed in the 1980s. But the age of the town does not decide whether a particular flat needs rewiring — the condition of the individual installation matters far more.
Older wiring has a limited service life. HDB states that PVC electrical cables have an estimated average lifespan of approximately 25 years, and advises homeowners to replace wiring when its lifespan has been exceeded or its condition has deteriorated. A Licensed Electrical Worker can assess the condition and advise whether replacement is required.
The more useful question
Not “how much does rewiring cost?” but:
“What condition is my existing electrical system in, and what actually needs to be changed?”
That is what a proper electrical assessment answers — before any package or price is discussed.
HDB Rewiring in Yishun
Renovating or moving into an older Yishun flat often involves more than adding a few sockets.
HDB’s electrical renovation requirements should be considered before work begins: wiring installation work in HDB flats must be carried out by an EMA-licensed electrical worker, and certain works may require HDB approval and testing through the relevant process.
What to consider
- Existing wiring condition
- Main switch and DB box condition
- Circuit arrangement
- Number and location of electrical points
- Air-conditioning requirements
- Water heater and kitchen appliance loads
- Concealed or surface wiring
- Additional circuits
- Electrical testing after new wiring work
Rewiring for Yishun Renovation Projects
A renovation is often the point when homeowners discover the existing electrical layout no longer suits how they use the home.
Adding several new appliances without reviewing the existing circuits and loading creates an installation that does not match the home’s actual requirements — so the electrical scope should be coordinated before walls, ceilings, carpentry and finishes are completed.
What usually changes
- Kitchen appliances
- Bedroom layouts
- Lighting positions
- Air-conditioning arrangements
- TV and entertainment areas
- Work-from-home areas
- Washing machine or dryer locations
- Water heater arrangements
- Built-in cabinets
- Additional power points
Full Rewiring or Partial Rewiring?
Not every Yishun home needs a complete rewire. The correct scope comes from the actual installation rather than a package chosen before the property has been assessed.
Full Rewiring
A complete replacement of the wiring throughout the relevant areas — considered when the existing wiring is significantly aged, deteriorated, unsuitable for the planned renovation, or when the layout is being substantially redesigned.
Partial Rewiring
Only selected circuits or areas are replaced or extended. Appropriate where the installation remains serviceable in some areas but needs changes in specific rooms or circuits.
Additional Circuits
Some renovations simply need additional circuits for new appliances or a change in electrical demand, without a broader rewire.
DB Box and Circuit Upgrades
Your DB box controls and distributes the circuits throughout the home. If you are adding appliances, changing the circuit arrangement or carrying out extensive rewiring, its condition and configuration should be reviewed. The work may involve:
- DB box replacement
- MCB arrangement
- RCCB-related work
- Circuit separation
- Circuit labelling
- Additional circuits
- Main switch considerations
A DB upgrade should be part of the overall electrical design, not an isolated replacement — see DB box upgrade Singapore.
Electrical Loading for Yishun Flats
Loading is another consideration when an older flat is being upgraded. HDB’s electrical guidelines distinguish between different flat installations, including flats completed on or after 1 January 1994 and those that have undergone MUP/HIP. It becomes relevant when planning combinations such as:
- Air-conditioning
- Water heaters
- Electric ovens
- Induction cooking
- Washing machines
- Dryers
- Other higher-load appliances
If you are unsure about your home’s loading, the installation can be assessed before the works are finalised — see electrical loading upgrade.
Concealed Wiring or Surface Trunking?
The choice depends on the property, the renovation scope and the applicable HDB requirements.
Concealed wiring gives a cleaner finished appearance but has to be planned around building and renovation constraints. Surface trunking can be the practical alternative where extensive hacking or embedding of wiring is unsuitable — HDB has specific restrictions on embedding wiring in structural elements, so the method should be checked before routing is decided. See concealed wiring Singapore.
Additional Power Points for Yishun Homes
Older layouts do not always match how modern households use their homes. During rewiring or renovation, homeowners often want additional points for:
- Kitchen appliances
- Refrigerators
- Washing machines
- Work-from-home desks
- TVs
- Bedroom charging areas
- Home entertainment equipment
- Water heaters
- Air-conditioning
- General household appliances
Rather than adding sockets wherever there is space, the layout should follow appliance location, circuit arrangement and available loading — see power point installation.
Electrical Work Around Yishun’s Established Estates
Yishun has developed through several stages, from its early HDB development in the 1980s to later town improvements and rejuvenation.
For electrical work, though, the specific flat matters far more than the neighbourhood name. Two homes in Yishun can have very different installations, which is why the scope should be based on the property rather than a standard assumption about every flat here.
What makes two flats differ
- Block completion date
- Previous upgrading works
- Existing wiring condition
- Previous renovation
- DB configuration
- Electrical loading
- Current appliance requirements
- Proposed renovation layout
What Can Affect the Cost of Rewiring in Yishun?
The cost cannot be determined accurately from the town name alone. A site-based assessment is far more useful than choosing a package before the installation has been looked at.
The scope depends on
- Flat type and size
- Existing wiring condition
- Full or partial rewiring
- Number of circuits
- Number of electrical points
- DB box requirements
- Electrical loading
- Concealed or surface wiring
- Wall and ceiling access
- Renovation requirements
- Appliance requirements
- Testing and compliance requirements
Planning Electrical Rewiring Before Renovation
If you are renovating a Yishun flat, the electrical planning should happen before the renovation reaches the finishing stage. Working through this checklist early avoids reopening completed renovation work later.
A practical checklist
- Where will the major appliances go?
- Which rooms need additional sockets?
- Does the kitchen need dedicated circuits?
- Will air-conditioning be installed?
- Are water heaters being replaced or added?
- Does the existing DB need upgrading?
- Is the existing wiring suitable for the renovation?
- Will wiring be concealed or surface-mounted?
- Are any HDB approvals required?
- What testing will be required afterwards?

Yishun Rewiring Questions
Do I need a rewiring contractor for an older Yishun HDB flat?
Not necessarily for every flat — the condition of the existing wiring should be assessed first. HDB states that PVC electrical cables have an estimated average lifespan of approximately 25 years and recommends replacement when the wiring has reached the end of its lifespan or its condition has deteriorated.
How do I know whether my flat needs full or partial rewiring?
An electrical assessment determines whether the existing installation can remain in service or whether selected circuits — or the entire wiring system — should be replaced.
Can you handle HDB rewiring in Yishun?
Yes. Electrical work in HDB flats must comply with the applicable HDB requirements, and wiring installation work must be carried out by an EMA-licensed electrical worker.
Does rewiring include a DB box upgrade?
It can be included where the installation requires it, but DB box work should be assessed separately as part of the overall electrical scope.
Can I add more power points during rewiring?
Yes. Additional points can be planned as part of the electrical layout, subject to the existing installation, circuit arrangement and applicable requirements.
Is concealed wiring possible in an HDB flat?
It depends on the property and the proposed route. HDB has specific restrictions on embedding wiring in structural elements, so the installation method must be planned according to the applicable guidelines.
Do new electrical works in an HDB flat need testing?
Applicable new wiring or extension works may require the relevant testing and submission process. The exact requirements should be confirmed for the proposed work.
Can electrical rewiring be done during renovation?
Yes, and renovation is often a practical time because walls, ceilings, carpentry and finishes may already be changing. The works should still follow the applicable HDB renovation requirements.
