Level 2 ASP + Every approval lodged by us
Level 2 electrician in Castle Hill.
Castle Hill spans older overhead fed streets and newer underground estates, which changes how every job starts. Thorntek works both, converting supplies to 3 phase, upgrading mains and switchboards and lodging the network application in house, on either side of the boundary that runs through the suburb.

Two networks run through Castle Hill
Every connection, mains upgrade and service alteration in Castle Hill is lodged with them and approved before energising. As a Level 2 ASP we lodge the application, do the work and arrange the energising in one program. You never deal with the network.
Meters too: we are accredited to exchange and upgrade meters on behalf of retailers, same day as the works, coordinated with your retailer.

Common questions
Is Castle Hill on the Ausgrid or Endeavour Energy network?
Castle Hill has both networks in it, older streets overhead and the newer estates underground, and which one supplies you comes down to your address. Thorntek is Level 2 accredited to Ausgrid and Endeavour Energy, so both kinds of supply are handled in house from application to energising.
Can you clear a defect notice in Castle Hill?
Yes. The items the network wants rectified sit on page two of the notice, and once we complete them we lodge the Notice of Service Work (NOSW) that closes the defect. Email photos of both pages to connect@thorntek.com.au and we will send back a fixed quote.
How much does a Level 2 electrician cost in Castle Hill?
It depends on the job, and in Castle Hill the first question is whether your street is overhead or underground, because that changes how a 3 phase conversion or mains renewal is built. We price each job as a fixed amount before work starts. Send the details through our contact page and we will quote it.
Who is responsible for the power line from the street to my house?
On an overhead Castle Hill street, the service line from the network's pole to the point of attachment on your house is yours, not the network's, and so is everything from there through to the switchboard. The rules put all of that work with a Level 2 ASP. If part of that run looks worn, call 1300 58 58 16.
The power is out or a line is damaged in Castle Hill. Who do I call?
Call Ausgrid on 13 13 88 or Endeavour Energy on 131 003 first, and 000 immediately if anyone is in danger. The network crew makes the street safe. After that, repairs on your side, the service line, the point of attachment and the meter box, are Level 2 work that Thorntek carries out.
