LTA governs the charger equipment itself, through the Electric Vehicles Charging Act (EVCA): type approval, certification as fit for use, and registration before it can operate. EMA governs the fixed electrical installation feeding that charger, through the Electricity Act and Singapore Standard SS 638: who is licensed to wire it, and how it is tested. BCA and SCDF sit alongside both, governing the building and fire-safety context the charger sits in, entirely separate from either electrical approval. Passing one of these does not mean you've passed the others, and a valid electrical test certificate from your LEW is not the same document as LTA charger registration.

Track 1: LTA and the Electric Vehicles Charging Act

The Electric Vehicles Charging Act (EVCA) gives LTA the legal framework to regulate EV charger safety from the equipment side, covering both upstream design approval and downstream use and maintenance registration. Three distinct steps sit under this track:

Type approval

Every EV charger model must obtain LTA type approval before it can be supplied in Singapore. Historically this meant compliance with Technical Reference 25 (TR25), Singapore's national EV charging standard first established in 2010 and progressively revised. Applications are made using TR25:2022 or TR25:2022+A1:2025 test reports, submitted through the OneMotoring portal; LTA has moved away from processing the older Letters of No Objection under the current regime. From 1 April 2026, TR25 has itself been elevated into a full Singapore Standard, SS 722, and existing chargers already type-approved under TR25 do not need to re-certify, while new chargers have a transition window (reported as around 2.5 years) before SS 722 compliance becomes mandatory. Verify the current transition deadline directly with LTA before planning a large fleet or multi-site rollout around it, as this is precisely the kind of date that gets refined as a new standard beds in.

Certification as fit for use

Once a charger model holds type approval and has been physically installed, it needs to be certified as fit for charging EVs by a charger equipment specialist, resulting in a Certificate of Fitness. This step is separate from, and comes after, the electrical installation testing an LEW performs on the wiring feeding the unit; the Certificate of Fitness speaks to the charger equipment itself operating correctly and safely, not to the correctness of the upstream electrical supply.

Registration and location approval

A Certificate of Fitness in hand, the charger must then be registered with LTA before it can be used, a requirement that applies to both residential and commercial installations. Registration also assigns the charger either restricted-access or non-restricted-access approval, and using a restricted-access charger in a non-restricted-access location is itself an offence. This is where connector choice becomes a compliance question rather than just a technical one: publicly accessible (non-restricted-access) locations in Singapore are limited to chargers with Type 2 AC and/or Combo 2 (CCS2) DC connectors. A charger with only a CHAdeMO connector may still be supplied and installed, but only for non-publicly accessible locations. We cover the connector standards themselves, and why this restriction exists, in our guide to Type 1, Type 2 and CCS2 connectors.

SS 722, in a bit more detail

Singapore Standard SS 722, effective 1 April 2026, replaces TR25:2022 as the national EV charging standard and is structured across four parts, developed through a public-private Working Group overseen by Enterprise Singapore and LTA, with standard development itself managed by the Institution of Engineers, Singapore (IES):

  • Part 1, Electrical Safety: general EV charging requirements, now extended to cover wireless charging stations, mobile charging systems, and battery swap stations for four-wheeled vehicles, categories the original TR25 did not fully anticipate.
  • Part 2, Low-Powered and Wireless Systems: covers vehicles with dedicated receivers charging by parking over an inductive pad, and introduces cybersecurity requirements for charging management systems alongside smart grid integration guidance.
  • Part 3, DC Charging: aligned with International Electrotechnical Commission standards, and reported to introduce stricter temperature controls, enhanced integrity checks on cable insulation, and more precise power output requirements than the previous TR25 revision, directly relevant to the kind of insulation and temperature verification a Fluke FEV500 performs.
  • Part 4, Battery Swapping and Mobile Charging: extends the standard's scope to four-wheeler battery swap stations and to mobile EV chargers mounted on vehicles for on-demand charging.

The practical read for anyone specifying or testing EV charging equipment in Singapore is that SS 722 sits above and alongside the international base standards (IEC 61851-1 for general conductive charging requirements, IEC 61557 series for insulation and continuity testing, ISO 15118/DIN SPEC 70121 for DC charging communication). SS 722 is the local layer that determines LTA type approval; the IEC standards are the international technical basis those local requirements build on.

Track 2: EMA and the fixed electrical installation

Separately from LTA's charger-equipment track, the Energy Market Authority (EMA) regulates the fixed electrical installation that supplies power to the charger, under the Electricity Act (Cap. 89A) and Singapore Standard SS 638 (Singapore's adoption of IEC 60364 for low-voltage installations).

Fixed EV chargers must be installed by a Licensed Electrical Worker (LEW) registered with EMA; EMA maintains the LEW list that both the electrical trade and LTA's registration process reference. The LEW's job is the wiring itself: sizing and installing the circuit correctly, ensuring earth fault loop impedance, insulation resistance, RCD protection and phase sequence all meet SS 638 requirements, and producing a Schedule of Test Results as the documented evidence. For new or significantly altered installations, this work also feeds into the Electrical Installation Licence Certificate or Electrical Work Certificate issued to SP PowerGrid confirming the installation has been tested and verified in accordance with SS 638.

This is the track most electrical contractors and facilities teams are already familiar with, because it is the same discipline that applies to any other electrical installation in Singapore. What trips people up is assuming it's the whole compliance picture for an EV charger specifically. It isn't. A perfectly executed LEW installation with a clean Schedule of Test Results says nothing about whether the charger unit itself holds valid LTA type approval, has been certified fit for use, or has been registered, and a charger missing any of those LTA-side steps is not legally permitted to operate regardless of how good the electrical work behind it is.

Where BCA and SCDF fit in, and why they're not an electrical approval at all

Neither BCA nor SCDF issue an electrical certification for an EV charger. Their role sits in the building and fire-safety domain the charger physically occupies, which is a genuinely separate compliance question from either the LTA or EMA tracks above, and one that's easy to overlook because it doesn't show up on an electrician's test sheet.

SCDF's Fire Code 2023 requires an emergency main isolation shut-off switch located within 15 metres of an EV charging station, a requirement first mandated around March 2022, specifically to allow first responders to cut power to both the charging station and the vehicle being charged in the event of a fire. Car parks more broadly are designed to the Fire Code to contain a fire within the car park structure for a stipulated minimum period before firefighters arrive, with enclosed basement car parks requiring sprinklers plus natural or mechanical ventilation to clear smoke, heat and gases. A dedicated multi-agency EV Safety Taskforce, co-chaired by LTA and SCDF and established in 2023, exists specifically to coordinate fire-risk management across this space, reflecting that lithium-ion battery fires behave differently from conventional vehicle fires (they can retain heat and re-ignite after visible flames are extinguished), a risk profile the Fire Code's car park provisions are built around.

The practical implication: a building owner or facilities manager installing EV charging infrastructure needs to satisfy the Fire Code's isolation switch and car park design requirements as a distinct workstream from the LTA type approval and EMA/LEW electrical testing tracks above, typically coordinated through the project's fire safety engineer or the building's existing Fire Certificate holder, not through the LEW or the charger supplier alone.

Putting the sequence together

  1. Design stage: confirm the charger model holds current LTA type approval (TR25 or SS 722 depending on the transition timeline), select a connector configuration compliant with the intended location's access status (Type 2/CCS2 for public locations), and, for the space itself, confirm the fire safety engineer has addressed Fire Code requirements including the emergency isolation switch.
  2. Installation: an EMA-registered LEW installs the fixed electrical supply to SS 638, producing a Schedule of Test Results covering insulation resistance, loop impedance, RCD protection and related tests.
  3. Charger commissioning: a charger equipment specialist certifies the installed unit fit for use, issuing a Certificate of Fitness, distinct from the LEW's electrical test results.
  4. Registration: the charger is registered with LTA, with location access status (restricted or non-restricted) confirmed as matching its intended use.
  5. Ongoing: periodic re-testing of the electrical installation (per SS 638 and the site's own maintenance schedule) and of the charger's own safety functions continues to apply, separately from any one-time approval steps above.

Compliance mistakes we see

  • Treating the LEW's electrical certificate as sufficient on its own. It covers the fixed wiring, not the charger's LTA type approval, certification, or registration status.
  • Installing a CHAdeMO-only charger in a location intended for public or visitor access. Publicly accessible locations require Type 2 and/or CCS2 connectors; a CHAdeMO-only unit cannot receive non-restricted-access approval.
  • Overlooking the Fire Code's emergency isolation switch requirement. This sits outside both the LTA and EMA electrical tracks and needs to be addressed at the building/fire safety design stage, not retrofitted after the charger is already commissioned.
  • Using an installer who is not an EMA-registered LEW for a fixed charger. Only a registered LEW can install or certify a fixed EV charger's electrical connection under Singapore's regulatory framework.
