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, across three distinct steps. Type approval: every EV charger model must obtain LTA type approval before supply in Singapore, historically via Technical Reference 25 (TR25), Singapore's national EV charging standard first established in 2010; applications use TR25:2022 or TR25:2022+A1:2025 test reports submitted through OneMotoring. From 1 April 2026, TR25 has been elevated into full Singapore Standard SS 722; existing TR25-approved chargers do not need to re-certify, while new chargers have a transition window (reported as around 2.5 years), a deadline worth verifying directly with LTA before a large rollout. Certification as fit for use: once type-approved and physically installed, a charger needs to be certified fit for charging EVs by a charger equipment specialist, resulting in a Certificate of Fitness, separate from and after the LEW's electrical installation testing. Registration and location approval: the charger must then be registered with LTA before use, assigning restricted-access or non-restricted-access status; using a restricted-access charger in a non-restricted-access location is an offence. This is where connector choice becomes a compliance question: publicly accessible locations are limited to Type 2 AC and/or CCS2 DC connectors, while a CHAdeMO-only charger may only be supplied for non-publicly accessible locations (see 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, structured across four parts developed through a public-private Working Group overseen by Enterprise Singapore and LTA: Part 1, Electrical Safety covers general EV charging requirements, extended to wireless charging stations, mobile charging systems, and battery swap stations; Part 2, Low-Powered and Wireless Systems covers inductive pad charging and introduces cybersecurity and smart grid integration requirements; Part 3, DC Charging, aligned with IEC standards, introduces stricter temperature controls, enhanced cable insulation integrity checks, and more precise power output requirements than TR25, directly relevant to the verification a Fluke FEV500 performs; and Part 4, Battery Swapping and Mobile Charging extends scope to battery swap stations and mobile chargers. SS 722 sits above the international base standards (IEC 61851-1 for general conductive charging, IEC 61557 series for insulation and continuity testing, ISO 15118/DIN SPEC 70121 for DC charging communication), the local layer determining LTA type approval built on that international basis.
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 supplying 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, whose job is the wiring: 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, feeding into the Electrical Installation Licence Certificate or Electrical Work Certificate issued to SP PowerGrid. This is the track most contractors are already familiar with, but a perfectly executed LEW installation 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 LTA-side step is not legally permitted to operate regardless of how good the electrical work is.
Where BCA and SCDF Fit In
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, a genuinely separate compliance question from either the LTA or EMA tracks, 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 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 in the event of a fire; car parks more broadly are designed to contain a fire 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, coordinates fire-risk management across this space, reflecting that lithium-ion battery fires behave differently from conventional vehicle fires, retaining heat and re-igniting after visible flames are extinguished. 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 and EMA/LEW tracks above, typically coordinated through the project's fire safety engineer rather than the LEW or charger supplier alone.
Putting the Sequence Together
At the 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 confirm the fire safety engineer has addressed Fire Code requirements including the emergency isolation switch. During 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. At 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. For registration, the charger is registered with LTA, with location access status confirmed as matching its intended use. Ongoing, periodic re-testing of the electrical installation and of the charger's own safety functions continues separately from any one-time approval steps above.
Compliance Mistakes We See
Treating the LEW's electrical certificate as sufficient on its own, when it covers only 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, when publicly accessible locations require Type 2 and/or CCS2 connectors. Overlooking the Fire Code's emergency isolation switch requirement, which sits outside both the LTA and EMA electrical tracks and needs addressing at the building/fire safety design stage, not retrofitted after commissioning. Using an installer who is not an EMA-registered LEW, when only a registered LEW can install or certify a fixed EV charger's electrical connection under Singapore's regulatory framework.
