If you’re working as a sparky in New Zealand, you already know the paperwork game: every job needs the right compliance documents, and the rules can be a bit of a headache if you’re not on top of them.
One of the biggest time-wasters we see is sparkies filling out separate Certificates of Compliance (COC) and Electrical Safety Certificates (ESC), when the truth is simple:
👉 Any general risk job that requires a COC also requires an ESC.
So why are so many of us still doubling up?
The Problem with Separate COC and ESC
Double handling – You’re writing out the same job, same details, same signatures twice.
More admin = more mistakes – Extra forms mean more chances to miss a box or forget a certificate.
Paper trails get messy – Especially if you’re juggling folders, PDFs, or emailing different docs to clients.
At the end of the day, it’s just wasted time – and time is money on the tools.
The Smarter Way: Combined COC/ESC
A combined COC/ESC does everything the law requires in one tidy document. Instead of juggling two certificates, you:
Fill in job details once.
Provide one clear record for the customer, inspector, or auditor.
Save yourself the admin headache.
It’s 100% compliant, it’s faster, and it keeps your paperwork clean.
