Under the Electricity (Hazards from Trees) Regulations 2003, WEL Networks can issue Tree Notices to the owners of trees that are growing too close to power lines, or are likely to do so in the future.

During routine inspections, patrollers assess trees near our electricity network. If a tree is found to be within, or likely to enter, the required clearance distance from power lines, the tree owner may receive a:

  • First Cut or Trim Notice, and/or
  • Cut or Trim Notice

The type of notice issued depends on the tree's history and previous maintenance requirements.

Read on for an explanation of each notice type, and what it means for you as a tree owner.

FIRST Cut or Trim Notice

WEL may cover reasonable costs of the first cut or trim of a tree growing too close to power lines if:

  • The tree HAS NOT previously been cut or trimmed at WEL's cost.
  • The tree is encroaching on power lines owned by WEL.
  • The property owner grants access to the site.
  • The tree is not part of a shelterbelt.
  • There is no existing agreement relating to the tree.

If these conditions are met, you may be issued a First Cut or Trim Notice. To be eligible, you must complete and return the notice by the date specified. This can be done online, by email, post, or in person.

If the notice is not returned within the required timeframe, you may lose eligibility for a first cut or trim at WEL's cost, and any required tree work may become your responsibility.

Cut or Trim Notice

If a tree on your property is growing too close to power lines, WEL may issue you with a Cut or Trim Notice if:

  • The tree HAS previously been cut or trimmed at WEL's cost.
  • The tree forms part of a shelterbelt.
  • The tree is subject to a previous agreement.
  • A local authority or adjoining landowner has declined responsibility for the tree.

Once you receive a notice, you are responsible for arranging the required tree work within the timeframe specified. The work must be completed by a WEL approved contractor and restore the required clearance from power lines.

You must also notify WEL at least three working days before the work is carried out, including the proposed date, time, and location.

To reduce future maintenance costs and improve safety, WEL recommends maintaining a clearance of 4.5 metres or more from power lines where practicable.

Tree work near power lines can be dangerous. If a tree is within 4 metres of a power line, or could fall onto a power line, do not attempt the work yourself and use one of our approved vegetation contractors.

Advisory Notice

An Advisory Notice is issued when vegetation is approaching the Growth Limit Zone (GLZ), and may become a risk to the electricity network in the future.

This notice gives you the opportunity to arrange tree maintenance before the vegetation enters the GLZ, where a formal Cut or Trim Notice may be issued under the Electricity (Hazards from Trees) Regulations 2003.

Taking action early can help avoid future compliance requirements, reduce the risk of power outages, and support the safe operation of the electricity network.
