Fully licensed HDB electrical wiring Singapore homeowners trust: new circuit wiring, DB box upgrades and full rewiring for BTO and resale flats, carried out to SS 638:2018 (formerly CP5) with same-day emergency response.

HDB electrical wiring Singapore covers everything from new circuit wiring and additional power points, to lighting point wiring, DB box (consumer unit) replacement, and full rewiring of flats still running on old rubber- or PVC-insulated cabling. It also includes pre-wiring for standard-load additions such as air-conditioning, induction hobs, and others necessary points. MM Engineering Works Complete every project by BCA skill workers and ensuring 100% quality works.
BTO electrical works mean wiring a bare, unfinished unit for the first time, usually planned around your renovation contractor's timeline before key collection. See our BTO Electrical Works Singapore guide for a full planning checklist.
Resale HDB rewiring is different — it usually means replacing ageing wiring and DB boards in a flat that's already occupied or partly furnished, so the work is planned to minimise hacking, dust, and disruption to the parts of the home you're keeping.
Costs depend on flat size (3-room to executive), whether you need a full or partial rewire, and whether it's bundled with a DB box upgrade. For a full breakdown by flat type, see our HDB Rewiring Cost Singapore (2026) guide. For an exact number, we quote upfront after a short on-site or photo-based assessment — no obligation.

Many older HDB flats still run on the original rewireable fuse board. Upgrading to a modern RCCB/MCB distribution board is one of the highest-impact safety improvements you can make, and is often required before adding higher-load appliances.
See our DB Box Upgrade Singapore page for full scope and pricing, including our 63A Main DB HDB Singapore testing guide for larger loads.
View DB Box Pricing →The clearest signs are a burning smell near the DB box or sockets, an original rewireable fuse board, or wiring older than 20–30 years. Repeated circuit breaker or RCCB trips are another common trigger — see our HDB power trip guide. For the full checklist across HDB, condo and landed homes, see our House Rewiring Singapore guide.
All wiring and DB box work on your new HDB flat should be tested by a Licensed Electrical Worker (LEW) before power on and comply with SS 638:2018, the Singapore Standard Code of Practice for Electrical Installations — many homeowners still know it by its older name, CP5. You can verify any electrician's licence for free on EMA's ELISE portal before work begins. Read more in our Singapore Electrical Rules guide.
