All companies, along with their workers and subcontractors, that wish to perform design or contestable work on or near Ausgrid's network must be accredited and/or registered with the NSW Department of Planning and Environment. They must also be authorised by Ausgrid as an Accredited Service Provider (ASP) at the appropriate level and class.

Any work to design, construct or install assets that connect a customer’s installation to our electricity network is classed as contestable work. Customers may be required to fund some or all of the cost of contestable work and have the choice of selecting an ASP to carry out the work.

Customers seeking to connect to our network should apply for a connection. Customers seeking an ASP to carry out contestable work should visit Energy NSW.
