Commercial Rewiring Singapore Office, Retail, F&B & Warehouse

A commercial rewire has to happen around your business hours, satisfy the MCST, your insurer and sometimes SCDF, and the cost of a wrong call is lost revenue. TRUST ELECTRICIANS delivers LEW-endorsed, CoC-issued, fixed-quote commercial rewiring for offices, shops, F&B, clinics, schools, gyms and warehouses.

Restaurant / F&B Kitchen Rewiring

The kitchen is the heart of an F&B operation, so a rewire here is high-stakes and time-critical.

Heavy-duty 16A / 32A outlets and isolators for kitchen equipment
Exhaust and ventilation fan wiring with the exhaust contractor
Water heater and dishwasher spurs
Dining area feature lighting, separate from the kitchen electrical

Minimising Downtime (After-Hours / Phased Work)

Most commercial rewires cannot interrupt the business. We minimise disruption in three ways.

Nights & weekends

After-hours work

Most of the rough-in and the DB swap happens at night or on weekends. Surcharges are published on our Electrical Services Price List.

Zone by zone

Phased work

For office refurbishments, we rewire floor by floor or zone by zone, keeping the rest of the premises live.

Critical systems on

Temporary power

Where a full outage is unavoidable, we arrange temporary distribution to keep servers, fridges and security running.

For F&B, we usually plan the rewire around a closed day (often Monday). For retail, we work within the landlord's fit-out window.

Commercial Rewiring FAQs

Straight answers about timing, staying open, cost, SCDF, phasing and CoC.

Ask on WhatsApp Call Us

How long does a commercial rewire take?

It depends on the scope. A small retail unit is typically 1–2 weeks; a mid-sized office or F&B kitchen 2–4 weeks; a large warehouse or factory 4–8 weeks. Power-off time for the DB swap is usually 4–8 hours; the rest is done circuit by circuit, often after hours.

Do I need to close my business during the rewire?

Usually no. We work after hours, on weekends or in phases. For F&B, we usually plan around a closed day; for retail, we work within the landlord's fit-out window.

What is the cost of a commercial rewire in Singapore?

Typical ranges: small retail unit (300–500 sqft) $6,000–$15,000; mid-sized office (1,000–3,000 sqft) $15,000–$45,000; F&B kitchen fit-out $12,000–$35,000; warehouse $25,000–$80,000+. See our Electrical Services Price List for current rates.

Do you handle the SCDF fire alarm interface?

We do the electrical scope: emergency lighting, exit signs and the fire alarm interface. The fire alarm itself is supplied and commissioned by an SCDF-registered fire alarm contractor, and we coordinate with them on site.

Can you do the rewire in phases?

Yes. For office refurbishments we typically rewire floor by floor or zone by zone, keeping the rest of the premises live. The phasing is planned in the site survey and detailed in the quote.

Do you provide a Certificate of Compliance (CoC)?

Yes. Every commercial rewire comes with a LEW-signed CoC and a full test report, which is what your MCST, insurer or SCDF will ask for.
