Victoria runs the CES scheme through Energy Safe Victoria (ESV). Solar systems and battery energy storage systems are among the work that needs a Certificate of Electrical Safety, so any installer working in Victoria meets it on almost every job.
What the CES is
A Certificate of Electrical Safety is the record that prescribed electrical work was completed and tested by a registered electrical contractor or an electrician working under one. The certificate is lodged with ESV, and the customer must receive a copy. Under the Electricity Safety Act, the certificate and the inspection rules are strict, with penalties for failure.
The timing
The commonly quoted figure is that the CES must be lodged within five days of completing the work. In practice the steps are:
- Complete and test the work.
- Complete the certificate and provide the required information.
- Lodge with ESV. Timeframes are counted in days or business days, with separate time rules for inspection of certain work and for giving the customer a copy.
- Inspection where required. Some work requires an independent inspection, and ESV sets how long that can take. If it is delayed, the contractor follows it up.
Because these timeframes are updated and counted differently in different places, treat “five days” as a good habit, and read ESV’s current page for the exact rule. Solar Victoria, which runs the household rebate, also has its own post-installation documentation expectations for rebate jobs; see Solar Victoria installer approval.
Who does what
- Electrician or contractor. Does the work, tests it and lodges the CES.
- Solar retailer. Needs the CES reference as part of the close-out.
- Network distributor. Receives its own connection application. See network by network.
- Customer. Receives a copy of the certificate.
How it fits with STCs
The CES and the STC claim are separate trails: state safety law on one side, a federal certificate scheme on the other. The STC claim does not turn on the CES number the way it turns on accreditation, but a system installed without the required CES is not a lawful installation, and the CES copy belongs in the same job file as the photos, serials and statements. Many traders ask for it. For the plain “do I need it” question see do I need a state electrical certificate to claim STCs.
From the desk: put the CES reference on the job card as a close-out item. A missing reference two months later is a call to the electrician you did not want to make.
What this means for installers
In Victoria, expect three parallel trails: ESV for the CES, the network for connection and the Regulator for certificates. Keep them tied together, and check that your electrician has lodged within the window. The STC process itself is on STC trading and how it works. Retention of documents is in how long to keep records, and Victorian household incentives are on the Victoria rebates page.
