Jobs in reviews

Fault-finding late at night until past midnight (May 2024); electrical work in a home (October 2024); a defective RCCB found and a single-phase DB troubleshot within an hour in a double-storey house with two DBs (July 2025); a call-out at 12.30am that went on until 4am after previous wiremen couldn't fix the problem (December 2025); three lamps tested to show the fault was in the lamp, which the customer returned to the seller (August 2026). One reviewer calls it a "db box expert".

Photos

All ten photos on its Google Maps listing were posted by the business; one is watermarked with its name and dated 29 September 2025. They show single-phase distribution boards with EPS, Maxguard and Hager breakers; a board with thirteen Maxguard MCBs and a Schneider RCCB; Khind fan regulators beside wall switches; a TNB meter board checked with a clamp meter and another meter board; an electric-car wall charger and a car charging; a stack of breakers on a Maxguard carton; and a large commercial switchboard.

Registers

We found 011-1148 1603 and the name JT Electrical Service in none of Suruhanjaya Tenaga's public registers of electrical contractors and competent persons (snapshot of 6 October 2026), nor in CIDB's contractor register (collected 13 October 2026). That doesn't prove the person doing the work isn't registered: registered wiremen are listed under their own name and phone. For wiring work, ask which registered wireman will test and sign off the job.
