We Stay With You After The Job Is Done
At Hai Khim Engineering Pte Ltd, after sales support is not an afterthought. It is a promise that we make to you before the first cable is laid. We understand that most EV charger installers hand over and move on — but we don’t. Whether you’re a homeowner with a single charger at your landed property, or a business managing a fleet of charging stations across multiple sites, our after-sales commitment is the same: responsive, reliable, and genuine.
Our After-Sales Support Promise
What You Can Always Count On
From the moment your charger is commissioned and registered, our in-house team remains fully accountable to you. This includes handling post-installation queries, scheduling proactive maintenance, responding to faults, and keeping your charger at its best.
Guaranteed Response Within 1 to 5 Working Days: Every query, every concern, every request — our team gets back to you within one to five working days without exception. No chasing. No waiting. Just a team that follows through.
Zero Ghosting Policy: Once you are a client with us, you will always have a dedicated point of contact be it you need a routine guidance, urgent troubleshooting, or simply want to check on your next maintenance date.
Proactive — Not Reactive: We do not wait for something to break before reaching out. Our team will proactively monitor your maintenance schedule, flag upcoming servicing due dates, and reach out to you ahead of LTA deadlines.

What Our After-Sales Support Covers
Every Stage of Your EV Charging Journey — After Installation (Not Exhaustive)
Post
Installation Queries
Have a question about your charger after handover? Not sure how a feature works, or want to verify something about your setup? Our team is on hand to answer any post-installation questions clearly and promptly.
Periodic Scheduled Maintenance
Under Singapore's EVCA, all EV chargers require periodic safety inspections. We will let you know when your next servicing is due. Our team will advise you further on the next steps, and the latest updates to the nation's guidelines.
Fault Reporting & Troubleshooting
If your charger develops a fault or the performance has dropped, get in touch with us. Our team will respond promptly to diagnose and resolve the issue. For more complex issues, we will provide a clear scope of work.
Charger Upgrades & Replacements
As your EV needs evolve, be it purchasing a new vehicle, expanding your fleet, or you simply require a higher charging output, our team will recommend the next best upgrade path for your existing installation.
Spare Parts & Component Replacements
Charging cables, connectors, RFID readers, and other components within the EV charger naturally wear over time. We supply and replace the required parts for the charger brands we carry — Autel Global, Schneider Electric, ABB Mobility, and SINEXCEL.
Regulatory Updates & Compliance Advisory
We are aware and understand that Singapore's EV regulatory landscape evolves regularly. Our team monitors all LTA announcements and SS72 updates, and will advise you proactively if any changes affect your installation.
