Overhead vs Underground Power Connections: Pros, Cons & Cost Factors

Temporary power poles can be connected either overhead or underground, and the right choice depends on your site conditions, layout, and budget.

Overhead connections run power via aerial cabling from the street connection point to your pole. They're generally quicker and more cost-effective to install, since there's no trenching involved. They work well on sites with clear overhead access and no conflicting infrastructure.

Underground connections run cable below ground level. They're often necessary where overhead access isn't practical — for example, sites with height restrictions, heavy vehicle movement near the connection point, or specific council/development requirements. Underground installs typically cost more, since they include the first 2 metres of underground cable run, with additional length charged per metre.

Cost factors to weigh up:

• Site layout and distance from the street connection point

• Any site access restrictions (cranes, scaffolding, vehicle movements)

• Council or development approval conditions

• How long you'll need the connection (hire term)

If you're not sure which suits your site, it's worth discussing with your builder or electrician before booking — we're also happy to talk through what we'd recommend based on your site details.
