Most Sydney homes receive electricity through overhead service lines connected from the street network to the property. While these power lines are common across older suburbs, many homeowners are unaware that parts of the electrical connection are privately owned and must be maintained by the property owner.
This confusion often starts when damage occurs or a defect notice is issued by Ausgrid or Endeavour Energy.
Many homeowners assume that because the lines come from the street, the electricity network is responsible for all repairs. However, Endeavour Energy and Ausgrid are responsible for the upkeep of the infrastructure along the street only. They are not responsible for the service line, the point of attachment, or any components linked specifically to your household.
In most cases, the electricity network provider is responsible for the infrastructure up to the street pole only. The overhead cable running from the street pole to your home, including the point of attachment, is generally the homeowner’s responsibility.
Let’s break down the basics of overhead electrical service lines, what causes damage, and exactly what to do if a problem occurs.
Understanding the Components
To identify a problem, you first need to know the parts of your system.
The Overhead Connection Line
The overhead electrical service line is the electrical cable that connects the power poles on the street to your property. In most cases, this cable runs directly from the street pole to your roof or fascia.
The Point of Attachment
The Point of Attachment is precisely where the overhead line connects to your dwelling from the main street grid. This is the critical handover point. It attaches to the bracket that secures the line to your home, which then runs into your switchboard.
Some properties use a private power pole instead of connecting directly to the house. These poles are commonly found on larger properties or where the street connection is located far from the switchboard.
Common Causes of Overhead Power Line Problems
Overhead lines are exposed to the harsh Australian elements. Generally, problems fall into two categories: accidental damage and electrical faults.
Electrical Faults & Environmental Wear
Electrical faults can develop over time due to various factors:
- Low-hanging cables: Cables can sag over time. They must be kept at a specific minimum clearance to prevent accidents, such as a truck passing beneath and snagging them.
- Tree interference: Trees and branches that grow too close to the service line will sway in the wind or break, causing disturbances or outages.
- Wear and tear: Physical damage or deterioration due to age can result in exposed or damaged wires.
- UV Damage: Years of exposure to harsh Australian sunlight can weaken the insulation of cables, making them brittle and unsafe.
Accidental Damage
Unfortunately, accidents happen. Common causes of sudden damage include:
- Falling branches: A tree branch may fall and hit the service line, causing immediate physical damage.
- Storm damage: Severe weather can damage the connection box or rip the attachment point from the house.
- Vehicle impact: Trucks inadvertently snag power lines. This frequently happens during deliveries or construction when a vehicle’s height is misjudged, putting immense strain on the riser brackets and breaking the attachment point.
- Faulty installation: Riser brackets with broken attachment points can result from incorrect installation practices or an inability to handle physical loads.
Who Is Responsible for Overhead Power Line Repairs?
It is vital to understand the boundary of responsibility.
Endeavour Energy and Ausgrid maintain the power supply up to the street poles. If they notice a defect on your private lines, they may observe it and send you a defect notice, but they cannot fix it for you.
In most situations, any damage or defects affecting the overhead service line from the street pole to your property must be repaired by the property owner using a licensed Level 2 electrician. The network providers will not provide help with power supply problems that take place within your property boundaries.
Signs Your Overhead Service Line May Need Repairs
It’s important to identify problems early before they become dangerous or lead to power outages.
Common warning signs include:
- Sagging overhead cables
- Flickering lights inside the property
- Visible cracks or exposed wiring
- Rusted or damaged attachment brackets
- Burning smells near the switchboard or connection point
- Tree branches touching service lines
- Loose cables after storms or strong winds
If you notice any of these issues, contact a Level 2 electrician immediately for inspection and repairs.

Frequently Asked Questions
Can I fix my own overhead service line?
No. Working on overhead service lines is illegal and extremely dangerous for unlicensed individuals. You must use an Authorised Level 2 Service Provider.
Who pays for the repair of the service line?
If the damage is on your property (from the point of attachment to the house), the homeowner is responsible for the costs of repair and replacement.
What if my power line is sagging?
Sagging lines are a safety hazard. If you notice a low-hanging cable, contact a Level 2 electrician immediately to assess the tension and clearance.
What should I do if a tree branch falls on my service line?
If a branch has fallen on your line but the line is still intact, contact a Level 2 electrician to safely remove it and inspect the cable. If the line is pulled down or sparking, stay away and call emergency services, then contact a Level 2 electrician for the permanent repair.
