Homes in Tengah and what they mean for electrical work

Moved into a new flat in Tengah and found the power trips when the oven, kettle and aircon run at the same time? Or want more sockets and lights than the flat came with? Here is what to know before you hire someone for electrical work in this town.

A town of brand new flats

According to HDB's property information dataset, HDB's Tengah town has 145 residential blocks with about 16,300 dwelling units, completed between 2023 and 2026. All of these units are in blocks completed in 1998 or later, and the tallest block is 16 storeys. HDB towns do not follow planning area borders. The Census 2020 dwelling data groups this area with others and gives no separate household figures for it, so the HDB numbers are the clearer guide here.

So most jobs in Tengah add to fresh wiring rather than replace old cables. Common requests are extra power points in bedrooms and the living room, ceiling lights and fans, points for ovens, induction hobs or water heaters, and finding out why a breaker trips once new appliances are plugged in.

Rules that apply to HDB flats

• Work on wiring, power points, switches, lighting points, consumer control units (the DB box) or circuit breakers needs an EMA Licensed Electrical Worker. Licences are held by individuals, so ask for the name of the person who will actually do the work and check it, as set out in EMA's guide to engaging licensed workers.
• HDB also requires electrical work in flats to be done by an EMA licensed electrical worker, according to HDB's renovation approval guidelines.
• Flats without higher electrical loading need an HDB permit before new 15A power points are installed for aircon or high-load appliances, per HDB's renovation approval guidelines. Find out whether your flat needs this before you buy the equipment.
• If the same contractor also offers aircon installation, HDB requires a BCA trained installer for that part of the job, as stated in HDB's approval rules.

Tripping power and the DB box

In a new flat, a trip usually points to something specific being wrong. It is rarely just bad luck. Note which breaker in the DB box tripped and what was running at the time. If it trips when one appliance is switched on, the problem is often that appliance or its point. Repeated trips across several circuits may point to a load that is spread badly. Do not keep resetting a breaker that trips again straight away, and do not open the DB box yourself.

When you compare quotes, ask the electrician to explain whether the fix is a repair, a new circuit or simply moving an appliance to another point. For new sockets or lights, agree on exact positions before work starts, because cutting into walls in a freshly painted flat leaves patching to do afterwards.
