As of April 1, 2026, the official standard for Electric Vehicle (EV) charging in Singapore has transitioned from Technical Reference 25 (TR 25) to the newly elevated Singapore Standard SS 722. This change, overseen by the Land Transport Authority (LTA) and Enterprise Singapore, is designed to accommodate emerging technologies like wireless charging and higher-power systems.
Here is the detailed, factual breakdown of the standard and how it impacts your home charger.
1. What is the SS 722 Standard?
SS 722 is the national safety and technical framework for the design, installation, and maintenance of EV charging systems. It is divided into four main parts to cover the evolving EV landscape:
- Part 1: Electrical Safety and General Requirements – The foundational safety rules for all chargers, updated to include mobile charging and battery swap stations.
- Part 2: Low-Powered & Wireless Charging (WPT) – A new addition specifically for wireless charging pads and low-power units (up to 2.3kW). It also introduces mandatory cybersecurity requirements for charging management systems.
- Part 3: DC Charging Systems – Focuses on fast chargers with stricter temperature controls and enhanced cable insulation checks to prevent overheating.
- Part 4: Battery Swapping & Mobile Charging – Guidelines for swapping stations (including those for heavy vehicles) and van-mounted mobile chargers.
Crucial Note: If your charger was already installed and “Type-Approved” under the old TR 25 standards, you do not need to re-certify it. There is a 2.5-year transition period (until late 2028) before compliance with SS 722 becomes mandatory for new chargers.
2. Does My Home Charger Need an Inspection?
Yes. Under the Electric Vehicles Charging Act (EVCA), all chargers must be periodically inspected to remain legal. However, the frequency depends strictly on whether your home is classified as a “Restricted Access” or “Non-Restricted Access” location.
Option A: Landed Homes (Restricted Access)
If your charger is in a private parking space within a landed dwelling-house (detached, semi-detached, terrace, or strata-titled landed house):
- Inspection Frequency: Every 24 months.
- Who Must Do It: A certified Equipment Specialist.
- Requirement: You must keep the Certificate of Continued Fitness for at least 2 years and provide it to LTA if requested.
Option B: Condominiums/Apartments (Non-Restricted Access)
If you live in a condo where the charger is in a shared carpark (even if it is a designated lot for your unit), it is typically classified as “Non-Restricted”:
- Inspection Frequency: * Every 6 months by an Equipment Specialist.
- Every 12 months by a Licensed Electrical Worker (LEW).
- Responsibility: Usually, the MCST (Management Corporation Strata Title) or the charging operator handles this, but if you own the charger privately, you are the “Registered Responsible Person” (RRP) and must ensure this schedule is met.
3. Compliance Checklist for Homeowners
To ensure you are 100% compliant with the 2026 regulations, verify the following:
| Requirement | Details |
| LTA Registration | Your charger must be registered with LTA and have an Approval Label (usually a sticker with a QR code) affixed to it. |
| LEW Installation | Fixed chargers must be installed by a Licensed Electrical Worker (EMA licensed). |
| Record Keeping | You must retain the Certificate of Fitness (issued at installation) and all subsequent Certificates of Continued Fitness (from inspections). |
| OBU Compatibility | Ensure your charger/tints do not interfere with the ERP 2.0 OBU signal, as this is now cross-referenced during some site inspections. |
What happens if I don’t inspect it?
Using an unregistered or uninspected charger is a criminal offense under the EVCA. Penalties for non-compliance can involve heavy fines, and in the event of a fire, your home insurance may be voided if the charger was not maintained according to the SS 722/TR 25 schedule.
