Nearly all apartment and unit blocks with multiple separate homes are Class 2 under the National Construction Code. It’s shown on the building’s certificate of occupancy or building approval.

Easy ways to check this:

1. Look at your electricity bill

Most retailers show the distributor or network operator somewhere on the bill. If your bill says SA Power Networks, you’re connected to their network.

2. Check your address on the SA Power Networks website

Go to the SA Power Networks outage or locality search page and enter your address. If the address is recognised and outage information is available, the property is within their network area.

3. Ask your electricity retailer

Your retailer can tell you the distribution network service provider (DNSP) for your National Metering Identifier (NMI). For most South Australian residential customers, this will generally be SA Power Networks.

You usually won’t need to find this yourself — most buildings that meet this requirement are already on the program’s list of addresses, and the application for conditional approval confirms this for you. If your building isn’t on the list, you can still apply.

Applications that are conditionally approved will receive access to an online Vendor Marketplace that will list program approved vendors.
