Electricians in the North region of Singapore

Electrical work across the North region's towns

The oldest flats in the North region are in Yishun. In HDB's Yishun town, about 47% of flats are in blocks completed in 1986 or earlier, and the median block completion year is 1987. Flats of this age often still have wiring and a DB box sized for fewer appliances than a home runs today. This is a common reason power trips when the aircon, oven and water heater run at once. Under the Home Improvement Programme, flats built up to 1986 have been eligible since 2007, and upgrading the electrical supply is one of the essential improvements. A precinct is upgraded only if at least 75% of eligible Singapore citizen households vote yes. Check your own block's status with HDB before you pay for a full rewire.

Woodlands sits in the middle. In HDB's Woodlands town, about 25% of flats are in blocks from 1986 or earlier, 35% from 1987 to 1997 and 40% from 1998 or later, with a median block completion year of 1996. HIP was extended in 2018 to flats built from 1987 to 1997, and works in each flat take about 10 working days. If a poll is coming up for your precinct, it can make sense to fix urgent faults now and plan bigger DB box or wiring work around the result.

Sembawang has the newest flats. In HDB's Sembawang town, about 91% of flats are in blocks completed in 1998 or later, the median block completion year is 2000 and the latest block was completed in 2025. Jobs here are more often extra sockets, new lights and tracing a single faulty circuit than replacing old wiring. The usual catch is adding a heavy appliance: HDB says flats without higher electrical loading need an HDB permit to install new 15A power points for aircon or high-load appliances.

Not every home is an HDB flat. The Census 2020 counts households by planning area, and planning areas do not share HDB town borders. Condos and apartments make up about 11% of households in the Sembawang planning area, 9% in Yishun and 7% in Woodlands. Landed homes are about 3% in Sembawang, 2% in Yishun and 0% in Woodlands. Condo owners must follow the MCST by-laws and should check with the MCST before renovation. Any change to common property needs the MCST's prior written approval.

Whatever your home, the electrician must hold the right licence. EMA requires a Licensed Electrical Worker for work on wiring, socket outlets, switches, lighting points, consumer control units or circuit breakers. Licences are held by individuals, so ask whose licence covers your job. For HDB flats, HDB also requires an EMA licensed electrical worker. If the job is next to a gas hob, note that home gas installation work can only be done by City Energy or a Licensed Gas Service Worker, not by the electrician.
