Dial Before you Dig

Working near underground cables

Dial Before You Dig is a free national service that helps property owners and contractors avoid damage to underground cables when carrying out construction work. 

As a registered asset owner, TransGrid has supplied Dial Before You Dig with information on our underground cable routes.

If you are planning or undertaking underground works, contact Dial Before You Dig on 1100 (toll free) or via the online enquiry portal, providing: 

  • the location of the work
  • type of construction activity (e.g. mechanical excavation, boring, drilling, landscaping)
  • details of the contract

Dial Before You Dig will pass your enquiry on to all registered members, including TransGrid, and affected asset owners will respond within two working days of receiving this information. TransGrid responses are now automated and dispatched within a couple of hours.

When necessary, we can provide a safety observer at no cost to advise and monitor work methods when construction takes place near our cables (depending on the type and location of the asset).
