When it comes to upgrading or installing power infrastructure, underground power often sparks a lot of debate. Some people see it as a pricey luxury. Others think it’s too hard to maintain or only suited to big commercial projects.
“Underground power is way too expensive”
The truth: While the upfront cost can be higher than overhead lines, the long-term savings often make up for it.
There’s no denying that digging trenches and installing underground conduits involves more labour and equipment than running aerial lines. But here’s what many people don’t realise: underground power tends to require far less maintenance over time. It’s also less prone to storm damage, fallen trees, and power outages.
If you’re factoring in lifetime costs, including repairs, replacements, and disruptions, underground power can be a cost-effective investment, especially for new builds or developments.
“It’s only for commercial or high-end properties”
The truth: Underground power is becoming more common across residential areas, especially in new suburbs or when upgrading outdated infrastructure.
Many WA councils and developers are now encouraging or even requiring underground installations in residential zones. Whether you’re subdividing a block, renovating an older home, or simply want to tidy up your street frontage, underground services are well within reach for everyday homeowners.
“You can’t access underground cables easily if there’s a fault”
The truth: Properly installed underground systems are designed for access and long-term reliability.
People often assume that if something goes wrong, you’ll need to dig up the whole yard. But that’s not the case. Underground cables are placed in protective conduit and laid to a clear depth with known alignment, making them easy to locate if needed.
Plus, with services like underground service location, we can pinpoint cables with advanced equipment before doing any work, avoiding unnecessary disruption.
“Underground power doesn’t handle load as well as overhead lines.”
The truth: Underground cables are just as capable, and in many cases, more robust.
Modern underground cabling is designed to handle all kinds of electrical loads, from standard household use to high-demand industrial systems. In fact, underground power often runs cooler due to the surrounding soil acting as insulation, which can improve performance and longevity.
As long as the system is professionally designed and installed (like we do at DJL), it’s just as powerful, if not more, than overhead setups.
“It’s not worth it unless you’re building from scratch.”
The truth: Retrofitting underground power is absolutely possible, and sometimes necessary.
Whether you’ve received a notice from Western Power, you’re modernising an older home, or you’re upgrading your driveway and want to remove overhead lines, undergrounding is a great option.
The Benefits You Can’t Ignore
Aside from durability and safety, underground power offers some underrated advantages:
- Better kerb appeal – Say goodbye to ugly poles and wires in front of your home.
- Improved safety – No risk of electrocution from fallen lines during storms.
- Reduced fire hazard – Especially important in bushfire-prone areas.
- Future-proofing – Supports modern infrastructure, including EV chargers and solar integration.
