Putting an EV charger in at home in Singapore is no longer a simple electrical job. Since the Electric Vehicles Charging Act came into force in December 2023, every charger must be type-approved, installed by a licensed professional, certified and registered with the Land Transport Authority (LTA) before anyone uses it.[2] On 1 April 2026 the national charger standard also changed, from TR 25 to SS 722.[1]
This guide explains, in plain terms, what the rules require, what you will pay for, and how the process runs from site visit to first charge. Every figure is linked to the official page it came from, with the date we read it.
SS 722: the EV charger standard that replaced TR 25
LTA and Enterprise Singapore elevated Technical Reference 25 (TR 25:2022) to a full Singapore Standard, SS 722, with effect from 1 April 2026.[1] The Ministry of Transport now describes SS 722 as Singapore's national EV charging standard, which superseded TR 25 on that date.[2]
If you are worried about a charger you already own, you can relax. Chargers type-approved under the earlier TR 25 standards do not need to be re-certified to SS 722. New charger models get a transition period of two and a half years before SS 722 compliance becomes mandatory.[1]
What SS 722 adds
- Part 1 covers general and electrical safety, and now also wireless, mobile and battery charge-and-swap stations for four-wheelers.[1]
- Part 2 covers low-power and wireless charging, and adds cybersecurity requirements and smart-grid guidance.[1]
- Part 3 covers DC charging, with stricter temperature controls, enhanced integrity checks on cable insulation and more precise power output.[1]
- Part 4 covers battery swapping and mobile charging, including heavy vehicles.[1]
In practice, the safe wording for any charger you are offered is "LTA type-approved, compliant with TR 25 / SS 722". Be wary of quotes that cite other standard numbers for EV chargers.
EV charger installation requirements in Singapore
Four rules shape every installation, whether it is a landed home, a condo car park or a commercial site.
- The charger model must be type-approved by LTA before it can be supplied.[3]
- A fixed EV charger must be installed by a Licensed Electrical Worker (LEW).[3]
- The installed charger must be certified by a charger equipment specialist, who issues the Certificate of Fitness needed for registration.[3]
- The charger must be registered with LTA before it is used. Allowing an unregistered charger to be used may be an offence.[4]
LTA also sets rules on where chargers go. In residential premises, a charger may only be installed or used where a vehicle may ordinarily park, and using an adaptor between charger and car, or an extension cord with a non-fixed charger, is an offence.[3]
Restricted-access versus shared locations
LTA calls a parking space within, or next to, a landed house under the same ownership a restricted-access location. That covers detached, semi-detached, terrace, linked, strata cluster houses and townhouses.[3] Publicly accessible locations, which include HDB car parks, malls and petrol kiosks, may only use fixed chargers with Type 2 AC and/or CCS2 DC connectors.[3] The category matters because it changes your registration fee and your inspection schedule, both covered below.
LTA EV charger registration: steps and fees
The charger owner, or their Registered Responsible Person, registers each charger with LTA before use. A third party such as the installer can register on the owner's behalf, and the registration mark must be affixed to the charger within 60 days.[4]
| Charger power | Restricted access (landed) | Shared access |
|---|---|---|
| Below 23 kW | S$375 | S$150 |
| 23 to 150 kW | S$750 | S$375 |
| Above 150 kW | S$750 | S$600 |
Transferring a registration costs S$35, relocating a charger costs S$35, and deregistration is free.[4] Most home chargers are below 23 kW, so a typical landed-home registration fee is S$375.
EV charger installation price in Singapore: what you pay for
Quotes vary because no two homes are wired the same way. When you compare them, check that each one covers the same items.
- The charger itself: an LTA type-approved model at the power your car and your supply can use.
- Cabling from your distribution board to the parking spot. Longer runs cost more.
- Any work your electrical supply needs before it can carry a charger safely.
- The LEW's installation and the equipment specialist's certification.
- LTA's registration fee, which is a government charge (see the table above).
Actual charging speed depends on the car as much as the charger: the vehicle's onboard charger, battery condition, state of charge, battery temperature and the current the car requests all play a part. A bigger charger does not always mean faster charging.
LTA EV charger inspection after installation
Registration is not the end. LTA requires periodic inspection, and the schedule depends on where the charger is.[4]
- Restricted access (landed homes): an equipment specialist inspection every 24 months.[4]
- Shared access (condos, commercial and public sites): an equipment specialist every 6 months, or an LEW every 12 months.[4]
Inspection certificates must be kept for at least two years.[4] With a SuperCharge.SG installation, the first inspection, required on installation, is included. Each later periodic inspection starts from S$150 per EV charger. Our EV charger and solar maintenance service can keep these on schedule for you.
Landed, condo or HDB: which rules apply to you
Landed homeowners have the simplest path: a restricted-access charger at your own parking space, registered at the landed fee and inspected every 24 months.
Condo residents usually need the MCST on board, because chargers go in common car parks. The voting threshold for condo resolutions to install EV chargers for residents was lowered to 50%.[2] Shared condo chargers may also qualify for the EV Common Charger Grant until 31 December 2026; our condo EV charger and ECCG guide for MCSTs explains how.[6]
Personal home chargers are not offered for HDB flats. HDB car parks are publicly accessible and are served by public chargers deployed under LTA's programme.[3]
If you plan to sell charging to other people, the rules change again: operators that provide EV charging services to the public need an LTA EV Charging Operator licence. Homeowners charging their own household's cars, and fleet owners charging only their own fleet, do not.[5]
How a SuperCharge.SG home installation works
- Site visit: we check your supply, distribution board, cable route and parking position, then quote.
- Installation by a Licensed Electrical Worker, who oversees every installation we do.
- Certification by a charger equipment specialist.
- LTA registration, which we do on your behalf, and the registration mark fixed to the charger.
- Handover: how to use the charger, and when its next inspection is due.
