Guide to NBN Lead-In Conduits for New Internet Connections

If you’re building a new home or connecting to the NBN for the first time, or upgrading from FTTN to FTTP, you may need a lead-in conduit (LIC) installed.
This guide outlines the process, timelines, and estimated costs involved in having us handle the conduit installation for your NBN connection.

What is a Lead-In Conduit (LIC)?

A lead in conduit is a PVC pipe that runs underground from the property boundary (usually the NBN pit) to your premises. It allows NBN-approved cables to be installed for internet connection.

When is a Lead-In Conduit Needed?

You will typically need a new conduit if:

  • Your property has never had an NBN service.

  • You are upgrading a direct buried copper service to fibre optic FTTP

  • You are constructing a new dwelling.

  • The existing conduit is damaged or non-compliant.

  • There is no direct underground path from the NBN pit to your property.

The Process – Step by Step

  1. Site Inspection:
    We visit your property to inspect the site, locate the nearest NBN pit, and determine the best path for the conduit.
    Estimated time: 1.5 hours

  2. Service Plan Design and Submission:
    Before any excavation begins, we prepare a Service Plan outlining the proposed conduit route and installation details. This is submitted to NBN Co for approval, which is required before proceeding.
    Estimated time: 2 hours

  3. Trenching and Conduit Installation:
    We dig a trench (typically 300–450 mm deep), lay the NBN compliant conduit (usually P20), and install sweep bends and draw cords.
    Estimated time: 2-3 hours for a simple install

  4. Compliance and Finishing:
    The installation is completed to meet NBN specifications. We supply photo documentation and plans if required to support compliance to NBN Co.

  5. NBN Connection:
    Once the LIC is in place and approved, NBN technicians can attend the site to complete the actual network connection. This is usually coordinated by your Internet provider.

Estimated Time and Cost

Our standard rate is $130 per hour (ex GST). Below is a typical breakdown:

Service Estimated Time Estimated Cost
Site inspection & consultation 1 hour $130
Service Plan design & submission 2 hours $260
Conduit installation (simple case) 2–3 hours $260–$390
Materials (conduit, sweep bends, etc.) — $50–$150
Estimated Total — $700–$1000

Note: Additional costs may apply for longer runs, complex terrain, or shared property access. We provide estimates before starting.

What You Need to Provide

  • Safe, clear access to your property

  • Preferred entry point location on your building

  • Any existing site or builder plans (if available)

Next Steps

Once your conduit is installed and approved, your ISP can arrange for NBN to connect your property. If you’re unsure whether your property requires this work, contact us and we’ll guide you through the process.
