How to install an EV charger at home in Singapore (landed homes)

This guide is for landed homes: terraces, semi-detached houses and bungalows, where you park on your own property. The EV Charging Act treats a parking space within, or adjoining, a landed house as a restricted access location, and that is where a private home charger belongs. LTA's guide for drivers says that at residential premises, chargers may only be installed in garages or designated carparks, and that you do not have to engage a licensed EV charging operator to run a charger at a private landed home.

If you live in a condominium or an HDB flat, the route is different. Condo chargers are shared, sit in common areas and need the management corporation's approval. Chargers in HDB carparks are deployed and operated by LTA-appointed EV charging operators. Our guide to EV charging at HDB, condo and landed homes explains what is possible in each.

One more thing to know before you start: there is no government grant for a charger at a landed home. You pay for the whole installation, so it is worth knowing what each part of it is for. Everything below is what our landed home EV charger installation covers, from the survey to the registration.

A home installation is a short sequence. Most of the paperwork can be done for you, but it still helps to know what each step is and who signs for it.

1. 1

   Tell us your car and where you park

   Your car model tells us the AC charging power it accepts. Where you park tells us where the charger will go and how far the cable has to run.

2. 2

   Free site survey

   A surveyor checks your incoming supply, the spare capacity at your distribution board, the cable route and the mounting spot, usually in 30 to 45 minutes, and quotes you on the spot.

3. 3

   Choose the charger

   You pick an LTA type-approved charger sized to your supply and to your car. We will not sell you a speed your car cannot use.

4. 4

   Installation day

   A Licensed Electrical Worker (LEW) installs the charger on its own protected circuit, with the cable run in neat trunking. An AC charger takes 1–3 hours on site.

5. 5

   Certification

   A charger equipment specialist certifies the charger. The Certificate of Fitness issued after installation and certification is what the charger is registered with.

6. 6

   LTA registration

   The charger is registered with LTA before it is used. We can submit the application for you; you then confirm the details on OneMotoring.

7. 7

   Registration mark

   Once registered, the charger must carry its LTA registration mark within 60 days of the registration date.

Two different times matter here, and they are easy to confuse. The installation itself takes 1–3 hours on site for an AC charger. From the day you approve the quote, you are typically charging within 1–3 days, which allows for booking the visit and getting the paperwork through. The one thing that can stretch that is a supply upgrade by SP, covered further down.

The survey is where the real decisions are made. A surveyor opens your distribution board, walks the route to where you park, and works out what your home can actually deliver. It is free, carries no obligation, and usually takes 30 to 45 minutes. What happens at the free site survey is set out in full on its own page; this is the short version.

To help the surveyor, have your car model ready, so we can confirm the AC charging power it accepts, and make sure someone can let us reach the distribution board and the parking spot. The person at home does not have to be you.

Once the survey has told you what your supply is, choosing the charger comes down to three questions: how much power the supply can carry, how much power the car can accept, and which features you want.

The car matters as much as the house. LTA puts it plainly: "Rate of AC charging is limited by the onboard charger." LTA's own example is a car that only supports single-phase charging, connected to an 11kW three-phase charger: it still charges at 3.7kW. A faster charger only helps if your car's onboard charger accepts the extra power, which is why the survey looks at the supply and the car together before recommending a size. Our guide to 7kW vs 22kW home chargers works through that choice in detail.

Whatever the size, the charger must be LTA type-approved: under the EV Charging Act, every model has to be approved before it can be supplied. The home chargers we install come from ten AC brands, all type-approved, all using the Type 2 connector that matches the AC inlet on EVs sold here, and all running on OCPP. For brands, smart features and warranties, read how to choose a home EV charger.

An AC home charger takes 1–3 hours on site. LTA requires a fixed charger to be installed by a Licensed Electrical Worker, and a tidy, compliant installation has three parts you can see for yourself.

• A dedicated circuit. The charger gets its own circuit from the distribution board, with its own breaker and residual-current protection (an RCD or RCBO), so it is protected separately from the rest of the house.
• Neat cabling. The cable runs in trunking or conduit from the board to the charger, along walls and edges rather than across the porch.
• Weatherproofing. Our outdoor installs are IP55-rated. Where the spot takes afternoon sun or driven rain, an optional canopy or charger housing keeps the weather off the unit.

Several people sign off a home charger, and it helps to know which is which. LTA fixes the order: a model is type-approved first, and only then is the charger installed, certified and registered.

The application asks for the charger's type approval ID and serial number, the installation address, the LEW's name and licence number, the equipment specialist's name and the Certificate of Fitness. LTA does not ask for photographs of chargers installed in landed homes.

Registration carries a fee. It is a mandatory fee paid to LTA, not to us, and it does not change the price of your installation. If you later transfer, relocate or deregister the charger, you must tell LTA. Our guide to LTA-approved chargers and registration covers the process in more detail.

Sometimes the survey finds that the incoming supply cannot carry a charger on top of the house's existing load, or you want three-phase charging on a single-phase supply. Work on the distribution board, or a charger with load management that limits its own power, can solve some of these cases. When the supply itself has to change, SP Group does that work, and it is a separate process with its own timeline.

SP treats an upgrade of the load at an existing home as a modification of connection. The homeowner engages a Licensed Electrical Worker, and the LEW submits the application through SP's eBusiness Portal. SP's FAQ for landed homes says a new service cable typically takes about three weeks for approvals, and about another three weeks for the cable work once approvals are in.

We do not publish prices, because no two landed installations are the same job. What we can tell you is what a quote is made of. Each part below is something the survey measures, so the quote you get after it is a firm figure rather than an estimate.

• The distribution board. With spare capacity and a spare way, the charger connects straight in; without them, the board needs work first.
• Protection. A dedicated circuit with its own RCD or RCBO, on every installation.
• The cable run. The distance and route from the board to your parking spot, and how much trunking it needs.
• The charger. Brand, power rating and smart features.
• Housing, if needed. An optional canopy or enclosure for an exposed spot.
• Certification and registration. The Certificate of Fitness and LTA registration, handled as part of the job.
