You don't normally need permission to plant a hedge or trees within a garden. And there no laws over how high you can grow a hedge, which can lead to issues between neighbours.
Resolve the issue with your neighbour
If you have an issue with a neighbour’s hedge, you should talk to them about the problem and try to reach a mutually agreeable solution.
You could send a polite letter, or if this still doesn’t work, invite them to talk to independent mediators who can help you find a way forward. Find a Civil Mediation provider on the Justice website.
Find out more on how to resolve issues about hedges from the Government information 'Over the garden hedge'.
Make a formal complaint
If you have followed the advice above and have not resolved the issue, you can make a formal complaint.
When you submit a complaint, we will sent a copy of your complaint to the owner of the hedge. We will remove your personal contact details from the copy we send them.
Determining high hedge complaints
If it is decided that a hedge adversely affects the reasonable enjoyment of your home and garden, then we can issue a remedial notice to the owner of the hedge setting out what must be done to reduce the height of the hedge, the time-frame for doing the work and what is required to prevent the problem happening again.
Complaining to the council about a neighbour's hedges should be a last resort.
