If you are concerned about trees overhanging your boundary you are able to exercise your Common Law right to maintain your boundary. Under Common Law you are entitled to prune back the branches or roots that grow over your boundary from neighbouring property, only to the boundary line but not beyond (that would be ‘trespass & damage’).
You are required to offer these branches/roots back to the owner, who has no obligation to accept them. If that's the case it's your responsibility to dispose of the pruned branches/roots responsibly. You are not entitled to deposit them on the tree owner's land without their permission (this would be regarded as fly tipping). Residents can dispose of this sort of waste at the Longshot Lane Household Waste Recycling Centre.
However, if the overhanging tree is protected under planning law, you will require the council’s written consent before you carry out any work. Examples of this are where the tree has a tree preservation order (TPO) or is within a conservation area. Pruning or removing such trees without permission is an offence in law.
