Where tall trees are already established, tree trimming is one way to maintain the required minimum clearance. Trimming your own trees near powerlines can be extremely dangerous. If a branch or ladder comes into contact with the lines or comes close to them, anybody touching the tree risks electrocution.

Western Power strongly recommends that you hire a tree-pruning professional who is insured and trained for working near powerlines. They can be found in the Yellow Pages under “Tree”.
Before employing a tree-pruner check that they have:
You need to ensure there is a safe distance of at least 2.5 metres between trees and powerlines on your property. Otherwise, trees need to be trimmed as soon as possible.
Branches can move about in strong winds and should be trimmed so that during storms and high winds they remain clear of powerlines. It is important to check and trim trees throughout the year, particularly before winter.
Trees that are diseased, weakened by storms, too large for the area, or structurally unsound, should be removed immediately.
It is a good idea to exceed the 2.5 metre clearance zone when trimming trees to a llow for regrowth and movement in strong winds.
The diagram below shows the minimum 2.5 metre clearance zone.
For information about tree species that are suitable to be planted near powerlines, please consult your local nursery, local council, or visit the planting guide section of this website.
In general, any trees on private property are the responsibility of the resident and any planted trees that are on the verge are the responsibility of the local council.
