DB Box Replacement Price Singapore - From S$380
Compare 6-, 12- and 18-way distribution-board price bands, then confirm whether you need a full board upgrade, one MCB/RCCB replacement or fault diagnosis first. Regulated electrical work is routed to an appropriately licensed electrical worker and the written scope is confirmed before work starts.
HDB circuit breaker box replacement price and scope
For an HDB circuit breaker box replacement price, compare the board size only after confirming whether the fault is in one MCB/RCCB, an appliance or the distribution board itself. The quote should identify the board and protection-device schedule, new or reused circuits, labels, testing, shutdown window and the responsible Licensed Electrical Worker where required. See EMA guidance on engaging Licensed Electrical Workers.
Upgrade, repair or diagnose first?
- Full upgrade: an old or undersized board needs more usable ways, a modern protection layout or renovation load planning.
- Breaker-only repair: one confirmed MCB or RCCB fault may not require replacing the whole board.
- Diagnosis first: recurring trips can come from an appliance, wiring fault, moisture or overload rather than the DB itself.
- Quote packet: send one full-board photo, a close-up of labels and breakers, property type, symptoms and planned new loads.
- Handover: ask for the agreed device schedule, test scope and any applicable licensing details in writing.

Replace the whole DB box, or just the breaker that keeps tripping?
A full board upgrade is not always the answer. Match the symptom you can actually observe to the smallest scope that can be quoted, then send the matching evidence so the coordinator does not price a full upgrade when one device or a diagnosis visit is the real need.
| What you are seeing | Sensible first step | Why | What to send |
|---|---|---|---|
| Same circuit trips repeatedly | Diagnosis first | A repeat trip on one circuit often comes from an appliance, wiring fault, moisture or overload rather than the board. | Board photo with that breaker in view, and what is plugged into the circuit. |
| One MCB or RCCB confirmed faulty, board otherwise sound | Device-level replacement | A single confirmed device fault may not require replacing the whole distribution board. | Close-up of the device rating, brand and the label beside it. |
| No spare way left for a new aircon, oven or water heater | Full board upgrade | The actual requirement is more usable ways, so board size drives the price. | Full-board photo plus the list of planned new loads. |
| Whole flat trips, or the trip returns after every reset | Diagnosis first | Recurring whole-premises trips point to a fault to be located before any board is ordered. | When it started, recent works or water ingress, and the full-board photo. |
| Old or undersized board with an outdated protection layout | Full board upgrade | A modern protection layout and correct labelling are part of the upgrade scope. | Full-board photo, close-up of labels and breakers, property type. |

A clear board photo and a short symptom history help avoid quoting a full upgrade when fault diagnosis or one breaker may be the real need.
FAQ
How much does it cost to change a DB box in Singapore?
Indicative planning prices start from S$380 for a 6-way board, S$580 for a 12-way board and S$780 for an 18-way board, with extra MCBs from S$40 each. Those figures cover the basic listed scope only. Board brand, protection-device schedule, fault diagnosis, access, new circuits and major material changes are stated separately, and any variation requires written approval.
Do I need to replace the whole DB box if one breaker keeps tripping?
Not necessarily. A repeat trip on one circuit often points to an appliance, wiring fault, moisture or overload rather than the distribution board itself, so diagnosis comes first. If a single MCB or RCCB is confirmed faulty and the board is otherwise sound, a device-level replacement can be quoted instead of a full upgrade.
Can a DB upgrade be done urgently?
Availability depends on the fault, board type, parts and whether regulated work must be scheduled. Send photos and your postal code so the coordinator can confirm the earliest eligible slot.
Do you charge for diagnosis?
The diagnosis fee and whether any credit applies are stated before booking. A recurring trip may require appliance or circuit testing rather than a full DB replacement.
What warranty applies?
Coverage depends on the written scope and parts used. Ask for the applicable workmanship and manufacturer terms on your quote before approval.
