What Rochor's housing means for electrical work

For electrical work in Rochor, the key number is 15A. In an HDB flat without higher electrical loading, you need an HDB permit to add a new 15A power point for an aircon or another heavy appliance, according to HDB's renovation approval rules. Official figures for Rochor itself are thin. The Census 2020 dwelling data groups this planning area with others instead of giving it its own line. HDB's property information dataset also gives no separate HDB town figures here, and HDB towns do not follow planning area borders anyway. So what matters most is the type of building you live in.

Every type of home has one rule in common. Work on wiring, socket outlets, switches, lighting points, consumer control units (the DB box) or circuit breakers needs an EMA Licensed Electrical Worker. Licences are held by individuals, not companies, so ask who will actually do the work and check that this person holds the licence. See EMA's guide to engaging licensed workers.

What this means for your home

HDB flats. HDB requires electrical work in flats to be done by an EMA licensed electrical worker. Before you plan extra aircon units or a new oven, find out whether your flat has higher electrical loading. If it does not, the 15A permit rule applies. Details are in HDB's guidance on applying for approval. If your power keeps tripping, start by noting which breaker trips and which appliance is running when it happens. A licensed worker can then trace the fault faster.

Older HDB blocks. The Home Improvement Programme was introduced in 2007 for flats built up to 1986. It was extended in 2018 to flats built from 1987 to 1997. Its essential improvements include upgrading the electrical supply. A precinct is upgraded only if at least 75% of eligible Singapore citizen households vote yes, and the works in each flat take about 10 working days. If your block falls in those age ranges, ask HDB about your precinct's status before you pay for a full rewire.

Condos. Strata owners must follow the MCST by-laws, so check with your MCST before any renovation. Changes to common property need the MCST's prior written approval. If you want to chase walls for new conduits, remember that structural elements cannot be altered without a Professional Engineer's assessment and approval from the Commissioner of Building Control. See BCA's guide for condo owners. Work on sockets, lights or breakers inside your unit still needs a licensed worker.

Landed homes and shophouses. Without an HDB or MCST layer, the main legal rule is the EMA licensing rule above. In older properties, ask the electrician to test the circuits and inspect the DB box before you replace individual sockets or lights, because the fault often sits upstream. If your kitchen renovation includes a gas hob, gas installation works can only be done by City Energy or a Licensed Gas Service Worker, as set out in EMA's gas safety rules. Your electrician cannot do that part.
