Compliance & Testing

We test and audit electrical installations in Singapore against SS 638 and SS 555, using our own Licensed Electrical Workers and test equipment, and give you a clear report of what to fix first.

What we test

• SS 638 compliance audits of the electrical installation
• Infrared thermographic scanning under live load (see our IR scanning page, with published prices)
• Power quality and power logger analysis: voltage dips, harmonics and load profile
• Earthing and bonding tests
• Lightning protection system tests to SS 555
• Periodic testing and certification by our LEWs

How a job runs

1. Tell us about the building and send the SLD if you have it.
2. Fixed quotation and an agreed test window.
3. Testing by our LEWs and thermographer.
4. Written report with findings ranked by severity and a recommended action for each.
5. If you want, repairs by our own crews and a re-test.

Why CSE

• In-house LEWs, a Level 2 certified thermographer and our own power analysers.
• Records you can keep for audits and insurance.
• One firm can find the fault, fix it and monitor the building afterwards with GEMS.
• Our own energy meters, monitored with GEMS, our own energy monitoring software, so you can see your energy use live.

Frequently asked questions

How much does an IR scan cost?

A single main switchboard site starts at S$700 before GST. Full rate card on the IR scanning page.

Do you need to shut down power to test?

IR scanning and power logging are done under live load. Some insulation and earthing tests need a short shutdown, which we plan with you.

How often should a building be tested?

It depends on the building and its licence. Our LEWs will advise a schedule for your installation.
