About 80% of Singapore homes are HDB, and HDB electrical work has its own DB layouts, cable specs, rules and paperwork. TRUST ELECTRICIANS works in HDB flats every day, from 3-room to EA, and knows the 2nd RCCB rule, the loading limits and the renovation guidelines inside out.
Registrations & certifications you can checkSingapore-registered and EMA-licensed
An HDB-experienced electrician knows HDB's renovation guidelines for electrical works, the SP Services loading rules, the 2nd RCCB requirement and the LEW paperwork HDB expects. Every HDB job we do complies with those guidelines, the Electricity Act and Singapore Standard CP5.
The CoC you receive after any HDB-relevant work is exactly what HDB asks for at resale and for future renovations.

WhatsApp a PhotoThe three HDB problems we get called for most often. Each has its own page with the full detail.
A circuit breaker keeps tripping, or will not stay reset. Usually an overloaded circuit, a faulty appliance, moisture or an RCCB doing its job.

Old fuse box, undersized DB, no spare ways, or a DB that feels warm or buzzes. An upgrade to a modern breaker DB usually includes the HDB 2nd RCCB.

A burnt, warm or dead water heater switch is a common HDB fault, and one you should not keep using. We replace the isolator and check the circuit and RCBO protection.

From BTO renovations to resale rewires and quick fixes, here is what Singapore HDB homeowners say about us on Google.
The two most common renovation contexts we work in, and what each usually involves.
BTO flats come with a basic installation: an 8–16 way DB, standard lighting points, a few 13A sockets, a cooker point and a water heater point. Most owners want to:
It is also the cheapest time to add the HDB 2nd RCCB.
Resale flats come with the previous owner's modifications, from perfectly fine to genuinely unsafe. What we often find:
A full or partial rewire is almost always part of a serious resale renovation. See Residential Rewiring.
We coordinate with your ID for the rough-in, DB upgrade, new points and final trim-out: usually 3–5 site visits across the renovation.
Tell us your flat type and what is happening. We give you a straight answer and a fixed price before any work starts.
The same licensed team handles condos and landed houses, where the technical work is similar but the rules and the scale are different.
We handle the MCST paperwork and access schedule. Where we are not already on the approved list, approval usually takes 1–2 weeks.

We are a BCA-registered, LEW-certified electrical contractor familiar with the HDB Renovation Guidelines for Electrical Works. For most HDB jobs you do not need a specific "HDB-approved" contractor; you need a licensed electrician who knows HDB requirements, which we do. For resale handover and renovation work, we handle the paperwork directly.
For most internal work (sockets, switches, lights, fans, DB upgrades), no HDB permit is needed as long as a licensed electrician does it. Some external work, such as running a new cable to the corridor, needs HDB permission. We tell you upfront if your job does.
It depends on the job. Typical prices: a switch replacement $80–$150, a new socket $180–$420, a DB upgrade $850–$2,200 and a full rewire $3,800–$9,500 depending on flat size. See our Electrical Services Price List for full rates.
Since 2024, HDB requires the socket circuit and the water-heater circuit to be protected by a dedicated 30mA RCBO. We install it as part of any new HDB electrical work and can retrofit it as a standalone visit. See our ELCB / RCCB Installation page.
Yes, that is the most common context. We coordinate with your ID for the rough-in, DB upgrade, new socket and fan points and the final trim-out, usually 3–5 site visits across the renovation.
In most HDB towns we can be on site within 60–90 minutes during working hours for diagnostic calls, and we book install work for the next available slot, usually within 2–3 working days. For emergencies, see our Emergency Electrician page.
