Commercial & residential subdivisions
There are two types of residential subdivisions, Urban Residential and Rural Residential:
- Urban Residential subdivisions have an average lot size smaller than 2,000 m2 and have frontages of 15 to 25 metres
- Rural Residential subdivisions have an average lot size greater than 2,000 m2 each.
There can also be Commercial subdivisions. The electrical infrastructure in new commercial subdivisions is designed according to lot size, unless you specify a higher load.
Charges for electrical infrastructure vary, as they are based on the individual requirements of each request.
Note: As a minimum, we require provision for a 3 phase 30 kVA supply to each commercial/industrial lot, unless otherwise notified and agreed.
For relevant specifications, refer to our manuals in the Document library.
There are two categories of subdivision:
- Contestable Subdivisions – Underground subdivisions only, typically involves more than two (2) lots
- Non-Contestable Subdivisions – Overhead subdivisions or where one (1) block is being split into two (2).

1 Enquiry
You will first need to decide who will be undertaking the design and construction of your subdivision electrical works. Subdivision construction is considered contestable work (excluding overhead supplied subdivisions which can only be constructed by us).
If you would like to use an approved service provider to design and construct the electrical works, please engage an Approved Subdivision Design Consultant (PDF 169.9 kb) who will complete the online developer enquiry form.
We will contact you within 5 business days (or other agreed date) to confirm details and provide more information on the process.
We’ll also provide you with a Works Request number. This number should be referenced on all future communications with us.
If you have multiple (two or more) stages, a Master Plan showing the lots and transformation locations for the entire development is required.
If a formal planning study is needed, we'll provide a quote and time frame for this work.
A design concept/master planning meeting can be requested by selecting the ‘Concept meeting’ check box when completing the developer enquiry form.

5 Construct
Site construction works may only commence following a pre-start meeting and confirmation that design plans have been reviewed and approved by us.
We need to inspect conduits or other such infrastructure before its buried or hidden from view. We may also do random audits at any time during the construction phase without notice.
We’ll conduct a final audit after construction is completed. Any defects found during this final audit must be rectified before a Certificate of Acceptance can be issued.

6 Connection
It’s important that you notify us of the expected completion date well in advance, so we can schedule the final testing and commissioning works. This helps to ensure the timely connection of the development.
