Overgrown gardens
What to do about a neighbour's overgrown garden
You can cut down overhanging vegetation from your neighbour's overgrown gardens, but only to the boundary point that runs between your property and your neighbour's.
You should talk with your neighbour first to discuss any issues and try to find a suitable resolution before cutting back vegetation.
It may be that your neighbour is having difficulty coping with the garden and would appreciate some support, maybe from yourself or perhaps from local charities or volunteer groups.
Damage caused by overgrown vegetation (such as damage to boundary fences) is a civil matter and you should get independent legal advice if this is the case. The Council is unable to assist in these matters.
If you cut back any overgrown vegetation, it is your responsibility to dispose of them, unless your neighbour has asked for them back. If you throw any cuttings back over your neighbour's fence, this could be considered fly tipping.
