A home electrical safety checklist for Singapore flats

Why a simple checklist helps

Electrical faults rarely announce themselves loudly. A warm socket, a plug that sparks when you pull it out or a breaker that trips now and then are easy to live with until something fails. A short, regular look around your home helps you spot problems early and describe them clearly when you call an electrician.

This checklist covers what you can look at safely without tools, the warning signs that need a professional, and how to brief an electrician. It is not a substitute for an inspection by a licensed worker. For the official view, read EMA's electrical safety guidance.

What you can check without tools

None of these checks involve opening covers or touching wiring. If anything looks wrong, stop and call an electrician.

• Sockets and switches: look for scorch marks, cracks, loose faceplates or plugs that fall out easily.
• Plugs and cords: check for frayed cables, exposed wires or plugs that feel hot after use.
• Extension cords and adaptors: avoid chaining them together, and do not run high-power appliances such as heaters or kettles from a crowded adaptor.
• The DB box: know where it is, keep it clear of clutter, and check that the circuits are labelled so you know which breaker controls which room.
• Wet areas: keep appliances and cords away from sinks, showers and the washing machine area.
• Smells and sounds: a burning smell, buzzing or crackling near a socket or switch is a reason to switch off that circuit and get help.

Warning signs to act on

Some signs mean a circuit should be checked soon, even if everything still works.

A breaker that trips repeatedly is the most common one. It can be caused by a faulty appliance, an overloaded circuit or a wiring problem. Try unplugging appliances on that circuit and resetting once. If it trips again with nothing plugged in, or trips every time a particular appliance runs, note the details and call an electrician. The power trip guide walks through what to note.

Lights that flicker across a whole room, sockets that feel warm with nothing plugged in, and switches that spark when used are also worth a professional check. So is any wiring that was damaged during renovation or by pests.

What to leave to a licensed electrician

Anything beyond plugging in, switching off and resetting a breaker should be left to a professional. That includes replacing sockets and switches, adding power points, changing light fittings that need wiring, working inside the DB box and any rewiring.

EMA's guidance on engaging licensed workers explains which electrical work must be done by a licensed electrical worker and how to check a worker's licence. Ask the company who will carry out your job and whether that person is licensed for it.

If you live in an HDB flat and the work is part of a renovation, read HDB's guidance on electrical works before you agree the scope. The licensed electrician guide covers how to check credentials in practice, the HDB electrical guide covers work in flats, and the wiring guide explains what a rewiring job involves.

What socket work costs, from published rates

Adding or replacing a power point is one of the most common small electrical jobs. The table below shows the lowest matching rate each company publishes for socket or power point work, with the source and capture date. These are advertised rates with conditions, not quotes; check what each company includes, such as trunking or the socket itself.

How to brief an electrician

A short, specific message gets you a faster and more accurate answer.

• Describe what happens, such as a trip when the oven runs or a socket that has stopped working.
• Say which room or circuit is affected and whether the problem is new or has happened before.
• Send a photo of the DB box and, if relevant, the socket, switch or light fitting.
• Say whether your home is an HDB flat, a condominium or a landed house, and whether it is under renovation.
• Ask for the inspection charge before the visit and agree the price of any extra work before it starts.

Keep a note of what was done and when, including any parts replaced. It helps the next electrician if the problem returns.

Make it a habit

A quick look around your home every few months, and again before festive periods when more appliances and lights are in use, is enough for most households. Pay extra attention after renovation work, after moving into a new home, and whenever you add a large appliance such as a water heater, an oven or a new aircon.

If a problem keeps coming back, do not keep resetting the breaker. A repeat fault is the circuit telling you something, and a licensed electrician can find out what.

Questions

Is it safe to reset a tripped breaker myself?

Resetting a breaker once after unplugging appliances on that circuit is a normal step. If it trips again straight away, or keeps tripping, leave it off and call a licensed electrician.

Can I replace a socket or switch myself?

Work on sockets, switches and wiring should be left to a licensed electrical worker. EMA's guidance on engaging licensed workers explains which work needs one and how to check a licence.

What should I send an electrician before the visit?

A short description of the problem, which room or circuit it affects, and photos of the DB box and the fitting involved. Ask for the inspection charge and agree any extra work before it starts.
