Trimming trees or vegetation that is too close, or overhangs, power lines can be extremely dangerous. If branches, trimming equipment or other items come into contact with power lines the results can be serious - injury or death, property damage, fires or power outages.

Know your tree trimming responsibilities

Tree owners are responsible for their trees; the results of tree damage to power lines can be a significant cost to a tree owner. Please check your trees, hedges or shelter belts regularly.

Why can trees cause outages?

Trees need to be kept a safe distance away from power lines and other electricity network equipment because:

  • Trees and vegetation coming into contact with power lines can cause power outages, not just for the tree owners, but the wider community.

  • Children that climb tree close to power lines are at risk of serious injury or death.

  • In severe weather conditions, vegetation can become electrically 'live' and may electrocute anyone coming into contact with it.

When do trees need trimming?

Notice Zone & The Growth Limit Zone

The regulations specify different zones for trees growing close to power lines and other electricity network equipment: the Notice Zone and the Growth Limit Zone.

If trees are in either the Notice Zone or the Growth Limit Zone they must be trimmed safely. Call us on 0800 30 90 80 for a free inspection and a quote from our utility arborists.

Fall Hazard Zone

Tree owners should be aware that trees present a hazard if they fall and damage power lines. The closest a tree can be located is calculated on the basis of the height of the tree plus 4 metres.

Check that your trees are outside the fall hazard zone and consider trimming or removal to avoid causing damage and incurring future costs.

Please don't wait to be reminded that your trees need to be cut. Be proactive, regularly inspect your trees and be aware that if your trees cause any problems on our network, you can be charged for all costs of repair.
