[ OVERVIEW ]

What are overhead and underground mains?

Overhead and underground mains are the cables that carry power from the street network to your property. They sit between the electricity distributor's network (Ausgrid or Endeavour Energy in Sydney) and your switchboard. This section of the supply is called consumer mains.

Overhead mains run as an aerial cable from a network pole to a point of attachment on your building or a private power pole. Underground mains run in conduit from a network pillar or pit to your meter box.

Work on these cables is not general electrical work. In NSW it must be done by a Level 2 Accredited Service Provider (ASP). We hold Level 2 ASP Licence 6855 and Contractors Licence 493243C. We coordinate network applications, install compliant consumer mains, and lodge the paperwork required to energise your supply.

[ SYMPTOM CHECKLIST ]

Common reasons property owners call us

  • Building a new home, granny flat, or extension that needs a fresh grid connection
  • Converting overhead supply to underground for safety, aesthetics, or council requirements
  • Storm or tree damage to an overhead service line or private power pole
  • Ausgrid or Endeavour Energy defect notice on service mains or point of attachment
  • Upgrading undersized consumer mains for EV charging, air conditioning, or workshop load
  • Frayed insulation, overheating, or visible damage on the aerial cable to your house
  • Removing a private power pole and switching to underground supply
  • Relocating the meter or switchboard during a renovation

If any of that matches your situation, this is Level 2 work and we handle it across Sydney every week. We can usually attend the same day for urgent storm damage or defect deadlines.

Things to understand before you book

Overhead vs underground supply

Overhead connections are generally faster and cheaper to install. The cable runs from a network pole to your point of attachment. Underground connections cost more upfront but remove visible cabling, reduce storm and tree risk, and are often required on new estates or by council. We assess your site, the available network connection points, and your budget, then recommend the best option.

Consumer mains and the network boundary

Consumer mains are the cables from the network to your main switchboard. The service fuse, metering equipment, and point of attachment also sit in this zone. Everything on the house side of the main switch is your general electrician's scope. Everything between the street and that switch is Level 2 ASP work under NSW law.

Level 2 ASP accreditation

Level 2 Accredited Service Providers are licensed electricians with additional accreditation from Ausgrid, Endeavour Energy, or Essential Energy. They are authorised to connect and disconnect properties, install service lines, and work on network-side equipment. Standard electricians who attempt this work risk fines, failed inspections, and extended outages.

Network applications and paperwork

New connections, conversions, and many upgrades need a connection application lodged with your distributor. After physical work is complete, your ASP submits a Notification of Service Work (NOSW) and coordinates inspection and energisation with the network. We manage the full application chain so you are not chasing forms between three parties.

Sam is an absolute legend. He fixed my hot water system this afternoon. He didn’t charge me a lot and he done a great job

Couldn’t be happier with Electrosurge Solutions. I had a full house rewire done and a bunch of upgrades like downlights, pendant lighting, new powerpoints, ethernet/data cabling, and exterior sensor lights. Sam is very tidy and everything looks and works perfectly. Really easy to deal with and you can tell they take pride in doing things properly. Definitely recommend if you want a quality electrician.

Frequently asked questions

01Do I need a Level 2 electrician for overhead or underground mains in NSW?

Yes. Any work on the service line between the electricity network and your switchboard must be performed by a Level 2 Accredited Service Provider under the NSW ASP Scheme. That includes new overhead and underground connections, repairs, conversions, and capacity upgrades on consumer mains. Standard electricians can work inside your property but cannot legally alter the network-side supply. We hold Level 2 ASP Licence 6855 and Contractors Licence 493243C.

02How much does overhead to underground mains conversion cost in Sydney?

A full residential overhead to underground conversion on a standard Sydney block typically runs $15,000 to $30,000 all-in, depending on trenching distance, surface types (lawn versus concrete driveway), pole removal, and whether your switchboard needs upgrading at the same time. We provide a fixed written quote after a site survey. Smaller partial underground runs or mains-only upgrades without pole removal sit lower in the range.

03What is the difference between overhead and underground mains?

Overhead mains are aerial cables from a network pole to a point of attachment on your building or private pole. They are quicker and cheaper to install. Underground mains run in conduit from a network pillar to your meter position. They cost more but look cleaner, survive storms better, and are often mandated on new developments. Both require a Level 2 ASP for installation, repair, or conversion.

04Can a regular electrician replace my consumer mains?

No, not if the work involves the network connection. Consumer mains between the street supply and your switchboard are Level 2 scope. A general electrician can replace internal wiring and may upgrade circuits inside your switchboard, but connecting or altering the service mains requires ASP accreditation. Using an unaccredited contractor risks non-compliance, failed energisation, and distributor penalties.

05How long does a new overhead or underground service connection take?

Timelines depend on network approval lead times and site complexity. Straightforward overhead connections often take one to three weeks from application to energisation once approvals are in place. Underground connections and full conversions typically take three to eight weeks because trenching, inspections, and network coordination add steps. We give you a realistic schedule when we quote.

06Who handles the Ausgrid or Endeavour Energy application?

We do. As your Level 2 ASP, we lodge the connection application with your distributor, manage technical design requirements, coordinate the work authority, complete the physical installation, and submit the Notification of Service Work (NOSW) after the job. You do not need to contact Ausgrid or Endeavour Energy directly unless you prefer to manage the retailer side of a new account.

07What causes damage to overhead service lines in Sydney?

Storm winds, fallen tree branches, and ageing insulation are the most common causes we see. Private power poles that have rotted or shifted also stress the aerial cable. Overloaded or undersized consumer mains can overheat at terminations. If you notice fraying, sagging, or buzzing near your service line, treat it as urgent and call a Level 2 ASP. Do not attempt repairs yourself.
