Electrician and Electrical Repair Services in Singapore

Diagnosis first, then a written repair quote

A breaker that trips is usually doing its job. The cause is normally elsewhere: a wet water-heater element, an appliance leaking to earth, a loose terminal or an overloaded circuit. A new breaker fixes none of these, so a power-trip visit has two parts, each approved by you.

1. Diagnosis: from S$60, diagnosis only. Circuits and appliances are isolated one at a time. You are told what tripped (the main RCCB or one MCB) and the cause. Diagnostic labour is quoted before it begins and credited in full toward the related repair if you go ahead.
2. Repair: quoted in writing, naming parts and work. If an appliance is the cause, you are told; the fix may be the appliance, not the DB box.

Known-scope work, such as replacing a named socket, has no diagnosis fee. See why the power trips in Singapore homes.

MCB, RCCB or RCBO: what exactly gets installed

• MCB (miniature circuit breaker): one per circuit; trips on overload or short circuit, not earth leakage.
• RCCB (residual current circuit breaker; older boards may say ELCB): usually one main device for several circuits or the whole home; trips on earth leakage, the cause of most whole-flat trips, but not on overload.
• RCBO: both in one device, per circuit, so a leak trips only that circuit.

They are not interchangeable: a new RCCB will not stop trips from a leaking heater, and fitting RCBOs depends on the board and its space.

Which device is fitted depends on the fault, the board and the circuit, and it is quoted in writing before anything is fitted. Background: what is in a DB box: MCB, RCCB and RCBO.

EMA advises testing your RCCB regularly with its test button (EMA: testing your RCCB); all lights and sockets should go off. If not, have it checked.

Price guide

Prices are indicative and confirmed on site before any work starts. Materials are billed separately, with no time-of-day surcharge.

What changes the price

• What diagnosis finds: a loose terminal is quick; a leak in concealed wiring is not.
• Parts: breaker type and brand, smart or USB sockets, your light fitting.
• Access and old wiring: concealed runs, high or false ceilings, a crowded DB box, wiring that will not take a new fitting.
• Licensing: whether the scope needs an LEW (below).

HDB, condo or landed

HDB flat. HDB's electrical works guidelines list works that need no HDB permit, subject to conditions; without higher electrical loading, a new 15A point for an aircon or other high-capacity appliance needs an HDB permit. No RCCB test button on your board? New homes have needed an RCCB since July 1985 (parliamentary reply, 5 July 2023), and EMA now requires one in every home (EMA: RCCB requirement); see DB box upgrade prices.

Condo or EC. Report common-property faults to the managing agent or MCST, who may also ask for notice or contractor insurance details before work in your unit. Our crews are insured.

Landed home. Larger boards and more circuits cost more than the HDB figure.

Who does the work

EMA's guidance on engaging Licensed Electrical Workers says home electrical work should be carried out or supervised by a Licensed Electrical Worker (LEW), including adding, extending or replacing sockets, switches and lighting points, wiring, and repairs to the DB box and its breakers. That is most jobs on this page. Plugging an appliance into an existing socket does not need one.

Electrical work that requires a Licensed Electrical Worker is carried out or supervised by an LEW. You can ask for the assigned LEW's details before work starts and check the licence on EMA's ELISE register.

How a booking works

1. Send a DB box photo (cover closed is fine), the faulty point, what was running when it tripped, whether the breaker resets, and your postal code.
2. Get a range or the questions needed to narrow it. Same-day slots when available, confirmed before dispatch.
3. On site, diagnosis or survey first. Price, scope and exclusions are confirmed in writing before work starts, including the exact devices.
4. Repair and test; you see what was installed.
5. Pay by PayNow, PayLah, bank transfer, cash or e-invoice. Warranty follows our warranty and refund policy.
