Key takeaways

• Wiring and rewiring is notifiable work — it must be done by an EMA Licensed Electrical Worker (LEW).
• Partial rewiring starts from S$150 per circuit; full-flat rewiring with a DB upgrade runs S$2,000–S$6,000.
• Older resale flats don't always need a full rewire — honest companies assess first.
• Flickering lights, warm switches and tripping breakers are your flat telling you something.

Old wiring is invisible until it isn't. Here's what rewiring costs, when you actually need it, and the licensing rules that protect you. Full rates in our electrical works cost guide.

How to choose well

1. The key requirement. Wiring and rewiring is notifiable work — it must be done by an EMA Licensed Electrical Worker (LEW).
2. For older resale flats, ask for an assessment first — not every flat needs a full rewire, and honest companies will tell you.
3. Reviews with specifics beat star counts. Look for reviews that mention your job type and how problems were handled — not just "good service".
4. Itemised quotes only. A lump-sum quote is where surprises hide. Line items let you compare fairly across companies.
5. Never pay fully upfront. Deposit, progressive payments, and a retention until the work is done and checked.

What it should cost

Partial rewiring starts from S$150 per circuit; full-flat rewiring with a DB upgrade runs S$2,000–S$6,000. For the full pricing breakdown, see our cost guide.

Prices move with scope, materials and access — treat any quote wildly below market as a red flag, not a bargain.
