Yeshua Electrical and Plumbing Services Pte. Ltd. is an electrician — plumbing is in the name too — based at #10-26, Blk 116B Rivervale Dr in Sengkang, Singapore, with a 5.0 Google rating.
Electrical jobs in an HDB flat run from a circuit that keeps tripping to extra points for ceiling fans or water heaters, and a good electrician will find the cause before quoting, since a tripping breaker is often one faulty appliance rather than the wiring itself. A firm that covers both trades earns its keep on jobs like an instantaneous water heater, where the pipework and the power point need doing together. It is worth checking that whoever does the work holds the appropriate EMA licence for anything beyond simple fittings, and agreeing the price before they begin.
For flats around Rivervale Dr and the wider Sengkang estate, that combination of trades makes Yeshua a useful number to have on hand.
