Whose job is it to trim trees near power lines?

A full-grown tree can be a thing of beauty, but not if it’s sitting directly underneath an overhead power line.

In this situation, overgrown trees can quickly become a public safety risk and interrupt the supply of electricity, especially in severe weather.

In this article, we look at who is responsible for trees near power lines and what to do if you notice one of your trees growing near a power line.

Who is responsible for trimming trees near power lines in the UK?

Legally, the owner of the property where the tree is growing is responsible for trimming the tree.

However, if a tree is growing near a power line, the energy company may decide to trim the tree and cover the cost. And they have the legal right to do so.

Expert advice on pruning trees near power lines

Checkatrade member Andy Baverstock from Acorn Tree Specialists Ltd recommends:

Firstly, any professional tree specialist company, like those found on Checkatrade, will automatically know what to do when you ask them for advice regarding tree growth near power lines. Power lines can be deadly so we recommend you always contact a professional regarding any planned work near power lines.

A knowledgeable tree expert will check the lines to see if they are insulated, again this is something for an experienced specialist who will know the dangers and understand from experience what to look for!

Andy highlights the importance of contacting your local electric company early as it takes considerable time to get assistance:

The second option before any planned work is to call your local electric company for help. They will send someone out to look and make sure any work can take place next to them. If not, then they will close down power whilst the works take place. This would normally take 6-8 weeks depending on how busy they are. Again, this is all a free service and no fees are to be paid for this. Make your plans first as you may not be able to commission an expert to do any work for many weeks.

How far should trees be from power lines?

It all depends on the type of tree and the height to which it will eventually grow. In Britain, the typical height of a power line ranges from 15 – 55m.

Several trees native to the UK will reach or exceed this height. It’s important to maintain a safe clearing distance between the tree and the power line at all times.

If a tree does start getting too close to the power line, then it’s important to have it trimmed to a safe clearing distance.

This safe clearing distance varies depending on the voltage of the power line and whether the tree is climbable.

Generally, for lines with a voltage less than 33kV, the clearing distance should be 3 metres – but only if the branch can support a person’s weight.

Similarly, the clearing distance should be 0.8m on any tree that cannot support a person’s weight.

How do I report a tree on power lines?

If you notice a tree on a power line, it’s best to contact the energy company operating it as soon as possible.

Although responsibility typically falls on the tree’s owner, the energy company might be willing to cover the cost of a tree surgeon.

If they don’t, you’ll need to trim the tree. Due to the dangerous nature of pruning trees near power lines, we always recommend hiring a qualified tree surgeon.

Reporting dead trees near power lines

Similar to trees on power lines, if you notice any dead trees near power lines, then contact the energy company immediately.

Dead trees pose a risk as they are more likely to fall in strong winds and storms. If they’re located near power lines, then they could damage the lines and cause havoc with the local power supply.

Dealing with neighbours’ trees near powerlines

If you notice a neighbour has a tree on their property growing near a power line, speak to them and remind them who is responsible for trees near power lines.

If the tree were to bring your neighbourhood’s powerline down, then everyone in the immediate area could end up without power for a prolonged period.

Can a power company cut a tree on my property?

Yes, they can. If your tree begins to interfere with the power lines above it, then the power company has a legal right to trim the tree.

It’s important to approach the power company before they’re forced to take action into their own hands. Many operators will cover the costs of tree surgery, should it affect their power lines.

However, if the company has to act without your consent and if the tree causes damage to the power line, you might end up footing the bill.

Who do I call if my tree falls on power lines?

If you’re concerned about a tree falling on a power line or if your tree has fallen on a power line, it’s important to contact the company that operates the power line.

Speak to the energy company about the issue, who will guide you on what to do next. Most companies offer this service for free, especially as it’s likely to cost them less than what it costs to replace the power line.
