Excavation & underground power
One contractor for the trench and the power.
Most electricians subcontract the digging. We don’t. Our crew digs it, lays it and connects it for homes, pools, sheds, factories and multi-unit sites.
What we dig for
If it needs power underground, we do it.
Underground power
New or replacement underground supply to homes and outbuildings.
Communications
Conduit for NBN and data.
Mains & sub-mains
Incoming mains and sub-mains to second buildings.
Pools
Power out to pool equipment.
Sheds & outbuildings
Workshops, garages and granny flats.
Factories
Supply and sub-mains for commercial and industrial sites.
Multi-unit sites
Underground power across townhouse and unit developments.
Why Charlyn
Two trades, or one crew?
When the excavator and the electrician are different businesses, you’re the one coordinating them, and paying for the gaps in between. We do both halves ourselves.

Yes. We dig the trench, lay the conduit and cable, and connect it at both ends, including any switchboard work the new building needs.
Yes. We do mains upgrades from single to three phase, with underground or overhead supply. It’s often needed for homes moving to EV charging, heat pumps and induction. Because we dig our own trenches, an underground upgrade is one job, not two.
