How much will it cost?

We'll provide a quote after we complete the scoping and design of your project.

*We require a minimum of 16 weeks to plan a transmission network isolation (de-energising a part of the transmission network). If you are planning works within the Danger Zone and it is possible a network isolation may be required it is important to consider this time frame.

Additional information you need to know

If you’re application is in relation to subdividing your land, there are a few conditions you need to meet before you can request clearance from the Western Australian Planning Commission (WAPC) or complete your built strata development. If we have asked you to apply for a new connection in order to meet our condition(s), it’s handy for us to know if it’s linked to a subdivision so we can collate all the right information to ensure the right checks and balances are undertaken.
