Trees around and below powerlines

When trees grow close to or into powerlines they pose a hazard to the lines and potentially people and properties. Trees on public land are maintained by councils, however trees on private properties fall under the property (and tree) owner’s responsibility. According to the Electricity (Hazards from Trees) Regulations 2003, homeowners are required to keep any trees located on their property a prescribed distance from network lines. This is crucial to ensure power is being delivered to the neighbourhood.

When does a tree close to a powerline require a trim?

You must keep your trees and vegetation clear of the growth limit zone around overhead network power lines. Depending on the type of network line, the trees need to be trimmed when they reach a certain proximity to the line. The below graphic and table – courtesy of our partner Vector – shows the details.

What to do when a tree is encroaching the powerlines?

Due to the high risk, only qualified and approved utility arborists, like Treescape should trim any trees within four metres of a network line.

Usually, the power company will issue a “cut or trim notice” to the property owner when they see a tree is encroaching the growth limit zone. Often the first cut is free of charge, and subsequent trims will need to be covered by the property owner. Your local power company will provide you with more information with regards to their notice procedures.

Our techniques follow best practice for utility arboriculture. Sometimes this may mean encouraging the growth of the tree to extend away from lines. We aim to ensure the health of the tree is not compromised and that it still has a good canopy wherever possible.

If you notice a tree on your property is encroaching the growth limit zone, you can also hire an approved utility arborist to trim – you don’t have to wait for the notice.

What to bear in mind when planting around powerlines?

To avoid the risk and future costs of trees growing too close to electricity lines it makes good sense to consider tree species and growth rates carefully before planting on your property.


See below a planting guide created in partnership with Vector for a list of suitable trees for planting under or near electricity lines.
