High load permit and close approach consent

High Load Permit and Close Approach Consent

Electricity can jump or ‘arc’ over gaps, so even getting too close to overhead power lines can be dangerous. Many objects like trees, string, rope and water conduct electricity. Equipment does not need to touch the line to be dangerous as electricity can jump or ‘arc’ over in a high voltage system.

Obtaining a permit is an important safety measure if you’re planning to carry out any task in close proximity to power lines or other equipment, or transport a load over five metres in height.

Close Approach Consent

Look up, down and around before carrying out any tasks such as tree trimming, painting, digging etc.

If your work is going to be within four metres of any power lines, poles, power boxes and cables - at any time - you must apply for a Close Approach Consent to be issued by Unison.

A Close Approach Consent is required for work places and on your private property 24 hours a day, seven days a week.

A Close Approach Consent ensures we are aware of the work you will be carrying out, so that we can arrange the necessary safety precautions to allow you to carry out your work safely.

Failing to get a consent when working within four metres of our network could result in serious injury, or fatal electrocution.


Please note, charges may apply if you require your power to be disconnected outside of the following hours: 8.30am - 4.00pm, Monday to Friday.

Choosing not to apply for a Close Approach Consent, or not following the guidelines once it has been issued, could not only endanger the life of you and your loved ones, it could also leave you liable for any costs associated with damage to assets.

High Load Permits

You must obtain a High Load Permit from Unison before transporting a vehicle or load over five metres in height.

Our power lines are located about five metres above the ground so if you’re planned to transport a vehicle or load higher than our power lines, it may be necessary for us to lift the lines in certain areas, or for one of our contracting staff to escort you along part of your journey.

If you fail to obtain a High Load Permit and cause damage to our network, you could be liable for significant costs for repairs.

Please provide a minimum of 15 working days' notice before the date you intend to travel.
