Getting power socket placement right during a renovation is one of those decisions you only notice when it goes wrong. A socket hidden behind the wardrobe, a bedside with no outlet, a kitchen counter where the air fryer and kettle fight over one point: these small misses turn into years of extension cords and adaptors. Sockets are cheap to add while walls are open, and expensive and messy to add afterwards.
This guide walks you through a practical, room by room way to plan where your power points go, how high they should sit and roughly how many you need, so you can hand your contractor and electrician a clear layout instead of deciding on the spot.
Start With How You Actually Live
Before you mark a single socket on a floor plan, list every device you plug in today and expect to add over the next five to ten years: phones, laptops, the router, a robot vacuum dock, fans, a dehumidifier, the rice cooker.
A few principles help:
- Plan for furniture first. Decide where the bed, sofa, TV console, desk and fridge will go before deciding on sockets. A socket is only useful if furniture does not block it.
- Think in pairs. A twin socket (two outlets on one plate) costs little more than a single and almost always pays off.
- Count devices, then add spare capacity. Whatever number you arrive at, add one or two more points per room for things you have not bought yet.
- Keep heavy appliances on suitable points. Ovens, induction hobs, water heaters, air-conditioners and washing machines often need dedicated circuits or isolators. Your electrician will advise on this, so flag every high-power appliance early.
In Singapore, electrical installation work in homes must be carried out by a licensed electrical worker (LEW), licensed under the Energy Market Authority (EMA). If you live in an HDB flat, renovation works also follow HDB’s renovation guidelines, and condo owners need to check the MCST (Management Corporation Strata Title) rules. Check current requirements with HDB, EMA or your MCST before work starts, since rules can be updated.
Room by Room Socket Checklist
The table below is a starting point for a typical home. Adjust the counts to your household size and habits.
| Room | Where sockets usually help | Height to consider | Typical twin points to plan |
|---|---|---|---|
| Living room | TV wall, both sofa ends, a corner for a lamp or fan, near the router | Low behind TV console, or mid-height if the TV is wall-mounted | 3 to 5 |
| Master bedroom | Both sides of the bed, dressing table, desk or reading corner | Just above bedside table height so plugs are reachable | 3 to 4 |
| Kitchen | Along the counter backsplash, fridge, built-in appliances, microwave or oven tower | Above counter height, away from the sink and hob | 4 to 6, plus dedicated points |
| Study or home office | Desk wall, printer spot, monitor arm area, charging station | At or just above desk height | 2 to 4 |
| Bathroom | Near the mirror for a hair dryer or shaver, only where permitted | Kept well away from water, per your electrician’s advice | 0 to 1 |
| Service yard | Washer, dryer, water heater if relevant, ironing spot | Per appliance and safety requirements | 2 to 3 |
Living Room
The TV wall is where most people underestimate. A modern setup can include the TV, a soundbar, a set-top box or streaming device, a games console and a router. Plan at least two twin sockets behind the console, and consider whether you want a concealed conduit to run cables from the console up to a wall-mounted TV. If you care about sound, read up on speaker placement and room acoustics before finalising, since speakers placed in the wrong spot will need power somewhere you did not plan.
Add a socket at each end of the sofa for charging and a lamp, plus a corner point for a fan or festive lights.
Bedrooms
Bedside sockets should sit a little above the height of your bedside table, so you can plug in a charger without crawling under the bed. Plan one twin socket on each side for a couple. If you have a dressing table, put a point beside it for a hair dryer or styling tools. For children’s rooms, think about the study desk they will use in a few years, and about safety. Our guide to child-safe electrical sockets and cables covers covers and cable management once the points are in.
Kitchen
Kitchens need the most planning. Map every countertop appliance: kettle, rice cooker, toaster, coffee machine, air fryer, blender, slow cooker. You may not use them all at once, but you will want them plugged in where they live. Spread twin sockets along the backsplash so no appliance needs to be dragged across the counter.
Keep sockets a sensible distance from the sink and the hob. Built-in appliances such as the oven, dishwasher, hood and induction hob typically need their own points or isolator switches, and the fridge needs a socket that remains accessible once it is pushed into place. Ask your electrician which appliances should be on separate circuits.
Study, Service Yard and Bathroom
For a home office, put sockets at desk height so you are not bending down every time you plug in a laptop. Add one near where a printer or shredder will sit. If you work from home, a dedicated point near the router helps keep your internet equipment running neatly.
In the service yard, plan around the washing machine, dryer and any water heater. Bathrooms are the most restricted area for electrical points because of water. Whether a socket is allowed and what type it must be is a question for your LEW, not a design choice.
Heights, Positions and Common Mistakes
There is no single “correct” height for every socket, and your electrician will follow applicable safety requirements. The practical approach is to match the height to the furniture in front of it:
- Behind low furniture, such as a TV console or bed frame, place the socket where it will not be fully hidden, or deliberately low so a cable can be tucked away.
- Above worktops, place sockets high enough that plugs clear the counter and splashes.
- At desks and bedsides, put sockets just above the surface so they are reachable.
Common mistakes to avoid:
- Placing sockets where a wardrobe, bookshelf or built-in cabinet will cover them.
- Forgetting the ceiling: fans, lights, projectors and smart speakers may need points or wiring in places you would not think of at floor level.
- Ignoring the entrance: a socket near the shoe cabinet is useful for a vacuum charger or a digital door lock’s backup charging.
Working With Your Contractor and Electrician
Once you have a draft, turn it into a marked-up floor plan. Many homeowners print the plan, walk each room with a pen and mark every socket with its height and whether it is single, twin or dedicated. Take photos of walls before they are closed up so you know where conduits run.
Before you sign off:
- Share the plan early. Give your interior designer or contractor the layout before hacking and wiring begins, not after tiling.
- Ask about your electrical load. More sockets do not mean more capacity. Your LEW can advise whether your existing supply and distribution board suit what you plan to run.
- Confirm costs in writing. Pricing for additional points varies by contractor and job complexity, so get a written quote listing each point.
- Check the switches too. Decide where light switches go at the same time, especially two-way switches for bedrooms and corridors.
- Keep records. File your final layout and any certificates your electrician provides with your home documents.
It also pays to understand what happens when things go wrong. Knowing which circuit feeds which room makes troubleshooting easier during a trip, and our guide on what to do during a power outage in Singapore explains the steps if the whole home loses power.
