What is underground service installation for new developments?
Modern developments are built with underground power as standard, and the underground service infrastructure — conduit runs, pits, pillars and consumer mains to each dwelling or lot — must be installed to the distributor’s reticulation standards. Castellano Electrical provides Level 2 ASP underground service installation for new developments across Sydney, coordinating with civil works so the electrical reticulation is right the first time.
Underground installation for a development is more than laying cable. It requires conduit and pit layout coordinated with the civil design, correct depths and separations from other services, pillars at the right positions, and consumer mains sized for each dwelling. We work from the network design, install the underground infrastructure during the civil phase, and bring each connection point to a state ready for energisation. Getting trenching and conduit right during civils avoids costly re-excavation later.
For developers and builders, coordinating the underground electrical works with the rest of the site program is where projects are won or lost on time. We schedule the underground installation to fit your civil and construction sequence, liaise with the distributor on standards and inspections, and deliver compliant reticulation ready for connection and energisation. From townhouse developments to multi-stage estates, we provide the underground service installation that the development’s connections depend on.
Why only a Level 2 ASP can do this work
Underground Service Installation for New Developments is work on the network side of your electricity supply — the connection between the distributor's network and your meter. A standard electrician is licensed for the wiring inside your property, but only a Level 2 Authorised Service Provider (ASP) is authorised to connect, disconnect or alter that supply. If this work is done by a non-ASP, the distributor will not energise it and it has to be redone.
Castellano Electrical holds Level 2 ASP authorisation for both Ausgrid and Endeavour Energy, so we can carry out underground service installation for new developments anywhere in Greater Sydney and manage the distributor process for you. You can read more about electrical licensing in NSW via NSW Fair Trading.

Distributor coverage & service areas
We provide underground service installation for new developments across both Sydney network areas. Your property's distributor determines the application process and standards, and we are authorised for both:
- Ausgrid: Ausgrid operates the electricity network across the Sydney CBD, eastern suburbs, inner west, lower and upper north shore, northern beaches, the Central Coast and the Hunter.
- Endeavour Energy: Endeavour Energy operates the network across Greater Western Sydney, the South West, the Blue Mountains, the Southern Highlands and the Illawarra.

What does it cost?
Underground development works are quoted per project based on reticulation length, lot count and civil coordination.
