What Is the Problem?

Pick the symptom closest to yours. Each one has its own page with causes, prices and what we do on site.

Tripped RCCB in a distribution board causing a power trip in a Singapore home
01

Power Keeps Tripping

A breaker or RCCB that trips again after you reset it is protecting you from an overload, a short or earth leakage. We isolate the faulty circuit or appliance instead of just resetting the board.

02

No Power or a Blackout

Half the home dark, or the whole unit off, usually points to the main switch, an RCCB, the HDB loading limit or a supply-side fault. We work out which, and restore power safely.

How we repair

Diagnosis First, Then a Fixed Price

Replacing parts until something works is how small faults become big bills. We test, show you the cause and agree the price before any repair.

  1. Tell us the symptom. Call, or WhatsApp a photo of the DB box, socket or switch involved.
  2. Test on site. Multimeter, insulation resistance tester and clamp meter to find the faulty circuit, device or cable.
  3. Fixed quote. We explain the cause and the options, with a price for each. You decide.
  4. Repair and re-test. The fault is fixed, the circuit is tested under load and power is restored only when it is safe.
$80–$120Diagnostic visitIf no repair is carried out
From $120Diagnosis + minor repairSame visit

Sparks, Smoke or a Burning Smell Right Now?

Switch off the main switch at the DB box if it is safe to reach, keep away from the affected point and call us. That is an emergency, not a booking.

The honest answer

Repair, Replace or Rewire?

Not every fault should be repaired. After testing, we tell you which of these makes sense and why.

Most visits

Repair

One faulty device, connection or short cable run, with the rest of the circuit testing sound. Fixed the same visit in most cases.

  • Loose or burnt connections
  • One failed socket, switch or breaker
  • A single damaged cable run
Worn or outdated

Replace

The device is worn out, undersized or no longer safe, so a new one is fitted. See electrical installation for new points and fittings.

  • Old breakers and RCCBs
  • Cracked or heat-damaged sockets
  • Fans and fittings past their life
Faults keep coming back

Rewire

When insulation tests fail across several circuits, repairs only buy time. A full or partial rewire is the lasting fix.

  • Wiring over 20 years old
  • Repeated faults on many circuits
  • Brittle or no-earth cable

Electrical Repair FAQs

What Singapore homeowners and businesses ask us most before booking a repair.

Do you take small electrical repair jobs?

Yes. A single socket, switch or breaker is a normal job for us, priced in writing before we start.

How much does an electrical repair cost?

A diagnostic visit is $80 to $120 if no repair is carried out, and a diagnosis with a same-visit minor repair starts from $120. Parts and larger repairs are quoted after testing.

How fast can you come?

Most repairs can be booked for the same day or the next day. For sparks, smoke or a burning smell, call our emergency line straight away.

Will I need a Certificate of Compliance?

Only when fixed wiring is replaced or modified, such as a new cable run, DB box or RCCB. A like-for-like socket or switch swap usually does not need one. We tell you upfront.

What if the same fault comes back?

Tell us and we will come back to check it. Finding the cause, not just the symptom, is why repeat faults are rare with us.

Can I send a WhatsApp photo first?

Yes. A clear photo of the DB box, socket or switch often lets us tell you what the repair involves and the likely cost before anyone visits.

Need an Electrical Repair? Tell Us What Is Happening

Describe the problem or send a photo. We will tell you the likely cause, the price range and the earliest slot, usually the same day.
