Level 2 ASP + Every approval lodged by us
Level 2 electrician in Castle Hill.
Castle Hill has older overhead fed streets and newer underground estates, with a network boundary running through the suburb. Thorntek converts supplies to 3 phase, upgrades mains and switchboards and lodges the application with either network.

Two networks run through Castle Hill
Every connection, mains upgrade and service alteration in Castle Hill is lodged with the network and approved before energising. As a Level 2 ASP, Thorntek lodges the application, completes the work and arranges the energising.
To confirm which network supplies your street, check your address against both networks' maps.
We are also accredited to exchange and upgrade meters on behalf of retailers, the same day as the works.

Common questions
Is Castle Hill on the Ausgrid or Endeavour Energy network?
Castle Hill is supplied by both Ausgrid and Endeavour Energy, overhead in the older streets and underground in the newer estates, so your address decides the network. Thorntek is Level 2 accredited to both networks.
Can you clear a defect notice in Castle Hill?
Yes. Email every page of the notice, including page two, to connect@thorntek.com.au for a fixed quote, and once the work is complete we lodge the Notice of Service Work (NOSW) that clears the defect.
How much does a Level 2 electrician cost in Castle Hill?
Castle Hill pricing starts with whether your street is overhead or underground, which changes how a 3 phase conversion or mains renewal is done. Every job is a fixed quote before work starts; send the details through our contact page.
Who is responsible for the power line from the street to my house?
In Castle Hill the owner is responsible from the network's pole on overhead streets, or its pit or pillar on underground streets, through to the switchboard. All of it is Level 2 ASP work; Thorntek is on 1300 58 58 16.
The power is out or a line is damaged in Castle Hill. Who do I call?
Call the network's faults line on Ausgrid on 13 13 88 or Endeavour Energy on 131 003 first, and 000 if anyone is in danger. Once the street is safe, Thorntek carries out the Level 2 repair of your service line, point of attachment and meter box.
