If you are digging on your property, underground cables are a potential hazard. We offer quick and efficient locations of cables to ensure you can get on with your ground works without impediment.

You should not undertake any excavations which may be in close proximity to cables without first contacting us on on 0800 HORIZON (467 496) to determine their exact location.

Most cables or overhead wires located inside the boundary of your property are known as mains or service lines or cables and are your responsibility.

Any digging required for building, fencing, planting trees etc in the vicinity of the mains or service cables is dangerous unless you know where they are. We can visit your property and locate the cables to enable you to dig safely.

If the cables are owned by Horizon Networks, we have plans showing their location. If the plans can accurately determine the cable location, copies of the plans can be made available free of charge.


We recommend that you familiarize yourself and those carrying out the work with the Work Safe guide on safety with Underground Services and the safe systems of work within it:
