Competent Electrician is an electrical repair firm whose listed base is Tengah, and whose stated service area is Boon Lay and the nearby estates. It deals with power trips, RCCB and circuit breaker faults, wiring faults, faulty distribution boards, damaged sockets and switches, water heater electrical faults, and installation and inspection work. Both homes and commercial properties are served. Where the job needs an EMA Licensed Electrical Worker, the firm says it can handle that as well. The listing gives its enquiry line as open 24 hours. Customers describe fast arrivals, one within half an hour, and a light fixed in under 15 minutes. Another had a distribution board fault sorted on a Sunday. A customer with faulty downlights says the firm fixed a problem an earlier electrician had made worse. Customers also call the crew professional, polite and efficient.
