Endeavour Energy network + Level 2 ASP 4869
Level 2 electrician in Castle Hill.
Three phase upgrades, private poles, underground connections and switchboards in Castle Hill, handled end to end by a Level 2 ASP accredited to Endeavour Energy.

What we see in Castle Hill
Add a pool, ducted air and an EV charger to a Castle Hill home and the original single phase supply runs out of headroom: lights dipping at dinner, breakers tripping in summer. We convert the supply to three phase and rebuild the board so everything can run at once.
Working around the Hills District
Sustained knockdown rebuild and greenfield activity creates heavy demand for mains upgrades and connection works on Endeavour's underground network.
We work here week in, week out. It is priced into the quote, not discovered on the day.
You will see our trucks around Castle Towers Shopping Centre, Castle Hill Metro Station, Norwest Private Hospital and Bernie Mullane Sports Complex: connections, defect clearances and switchboard work in the surrounding streets.
Endeavour Energy runs the network in Castle Hill
Every connection, mains upgrade and service alteration in Castle Hill is lodged with Endeavour Energy 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.
The defect notices we clear most often around the Hills District:
- Mains upgrades on knockdown rebuild greenfield blocks
- Pit and pillar damage from civil works in growth corridors
- Commercial switchboard upgrades in Norwest business park
- Attachment point defects on acreage with long private service runs

Common questions
Is Castle Hill on the Ausgrid or Endeavour Energy network?
Castle Hill is on the Endeavour Energy network. Thorntek is accredited to both Ausgrid and Endeavour Energy, so it does not change who you call. Send us the job and we lodge every application and approval for you.
Can you clear a defect notice in Castle Hill?
Yes. Send every page of the notice to connect@thorntek.com.au. Page two carries the detail and the network's photos. We assess it, give you a fixed quote, complete the rectification and submit the Notice of Service Work (NOSW) to clear it.
How do I get a quote in Castle Hill?
Send photos and your property details through our contact page. We assess from there, add a free site visit if it is needed, then come back with an accurate fixed quote, not an estimate that creeps.
Do you handle commercial jobs in Castle Hill?
Yes. Every aspect of Level 2, residential and commercial. Commercial changeovers run as a planned shutdown executed in a day, and bigger involved supplies stay live on a backup generator while we work. Call 1300 58 58 16 to talk it through.
