Underground Power Lines Installation Service - Perfect Power Skip to main content

What Are Underground Power Lines

Underground power lines, also known as underground services, carry electricity through cables buried beneath the ground, connecting your property directly to the supply network. Instead of running overhead, these cables are installed in protective conduits from a pole, pit or pillar to your main switchboard. This setup offers a neater look, improved safety, and less exposure to damage from weather or falling branches.

At Perfect Power, we install underground power lines for new builds, property upgrades, and replacements. Our team ensures each connection is planned and installed to suit your site requirements, giving you a reliable electrical connection without visual clutter.

Whether you are building from scratch, upgrading from overhead, or replacing damaged supply lines, underground installation can be the right choice for both appearance and safety.

Why Should You Choose Underground Power Lines?

Underground power is your form of supply when the network in your area runs below the ground, meaning there are no poles or wires overhead.Underground service cables connect from the nearest utility company’s network pillar to your point of attachment. This can be your private pillar or your main switchboard. But! It’s not only streets with underground power that can benefit from the install of underground service cables, you can also install underground cables from the overhead network (poles and wires) by the form of a UGOH (under ground to overhead connection), where we run the cable down the pole and then underground into your property.

One of the main advantages is the absence of visible wires, which reduces the risk of damage during bad weather. It also creates a cleaner look in your surroundings without poles scattered around the streets.

You may need new underground services for situations such as:

  • Building a new housing estate
  • Setting up a private network
  • Upgrading to 3 Phase supply
  • Installing mains underground for large supply needs
  • Providing temporary builders’ supplies

They also improve street appearance by removing poles and overhead wires, making them popular for residential developments or upgrades. For properties with limited space or tricky access, underground connections can be designed to fit the site’s layout without crossing boundaries overhead.

Common uses include new housing estates, upgrading from existing overhead supply, replacing damaged underground cables, and installing higher-capacity connections for larger power needs.

How Can Underground Power Lines Save Costs in the Long Run?

Installing underground cables involves more upfront work compared to overhead power lines, but the long-term benefits can make it worthwhile. With fewer risks from storms, wind, or falling trees, there’s less chance of damage that could lead to costly repairs.

Underground lines also last for decades when properly installed, which reduces the need for frequent maintenance. For developments or property upgrades, they can also increase visual appeal and, in some cases, property value.

Government incentives or local council support may be available for certain undergrounding projects, helping to offset installation costs.

FAQs

What is the process for changing from overhead to underground electrical service?

Changing from overhead to underground involves removing the overhead cables and installing underground cables through trenches or conduits. An electrician and authorized accredited service provider will connect these cables to your home’s switchboard and arrange for any required inspections.

What is involved in residential underground power installation?

For a home, this usually means trenching from the street supply to your property, laying the cables, backfilling the trench, and connecting the system to your switchboard. A licensed electrician and accredited service provider will ensure it meets local standards. It could also require cutting and opening the council path or road, but don’t worry, Perfect Power will arrange all of the council permits and restoration works to provide an easy, no fuss experience for our clients.

What is the process for an underground powerline upgrade in the Northern Beaches?

An upgrade may involve replacing older cables with higher-capacity ones, improving insulation, or rerouting cables for better reliability. Our electricians and accredited service providers can assess the condition of the existing setup and recommend the best approach.

How do underground power cables differ from overhead cables?

Underground cables are insulated and buried below ground, while overhead cables are suspended on poles and exposed to weather. Underground setups are protected from wind and falling branches but require digging for repairs.

What our clients say



  • I am a tough marker but I can say that these guys are the ones you want on your roof. I wanted a solar array installed on the roof of my home. Another leading solar company told me it was too hard for them to do because it would take too much time and they were too busy. I called Perfect and spoke with Elliott Lane who promptly came to my home and conducted a site inspection. I was assured that Perfect had the know-how and experience. The installation team, Tom and Smiley went about the task of installing the solar array over four different facing roofs in a prompt and efficient manner. The finished product is all that was promised and they left the work site spotless.

  • I strongly recommend Elliott and his team. His proposal was thorough and convincing, the installation happened on time as planned. Communication throughout was perfect. Elliott was the only person I spoke to that didn't hesitate to jump straight up on the roof - none of the other companies were nearly as committed. This gave me great confidence in what he was recommending.
