You should talk to your neighbour about the overgrown garden first, if you can.

Cutting hedges or trees

You can prune or remove vegetation that grows onto your side of the boundary from a neighbour’s garden. For example, a hedge or a tree.  

Before trimming a tree, you should check if it's protected by a tree preservation order (TPO). 

You’ll need to apply for permission to do work on a tree with a TPO. 

Do not trespass onto land you do not own or live on to remove anything. 

Find out more about your rights if you disagree with a neighbour about a tree or hedge.
