How much will it cost?

We will provide you with a quote.

What if I change my mind or want to cancel my application?

Sometimes your circumstances change and you may need to cancel or change the information within your application after you have submitted it to us.

If you wish to change the scope of work in your application we will first review the change and then either:

  • continue the project with the variation and invoice you for any additional materials, design work and remobilisation costs incurred. We will typically only take this approach when the change is very minor.


  •  if the change is significant we will cancel your project. You will need to submit a new application with your new requirements.

For cancelled applications we will invoice you for the costs incurred up to the point of cancellation (time and materials). If construction work has already commenced we will refund the difference from your access offer less any costs incurred.

Fees and charges

Following the cancellation, expiry, termination or variation of the Customer Work Request or any other aspect of the works or documentation relating to the works, the customer may be liable to pay an administration fee of $550 (inclusive of GST) and any additional costs incurred by Western Power. Further information can be found in our Terms and Conditions clauses 8 and 16.3.
