Tree preservation orders (TPO)

If you would like work to be done on a tree, which is covered by a Tree Preservation Order (TPO), you will need to submit a 'Works to Trees' application before any work is started.

To find out if a tree is covered by a TPO please view our map below.

If the tree is not covered by a TPO, then any pruning or removal works are allowed to be carried out without prior permission from the council, providing that the property is not located within a Conservation Area.

Where a tree is in a conservation area but not protected by a Tree Preservation Order, permission also needs to be sought from the tree officer via [email protected]

'Work to Trees' application

You can apply for work to be done on a tree, which is covered by a TPO.

For more information you can view our TPO frequently asked questions.

TPOs can be served to stop a tree or group of trees from being felled. On occasions it is necessary to fell trees, for example to make way for property developments or if the trees themselves are poorly managed.

In order to successfully serve a TPO you need to demonstrate that the loss of the tree(s) will result in a negative impact on the surrounding area, for example reducing the public's ability to enjoy the location of the tree(s). This can be claimed if:

  • the tree is normally visible from a public place such as a road or footpath (although exceptions can be made if other trees are blocking the view)
  • the benefit may be present or future eg if the trees are not yet fully grown and will in time be visible
  • the trees are worthy of preservation for their intrinsic beauty or for their contribution to the landscape
  • they serve to screen an eyesore or future development
  • their value is enhanced by their scarcity
  • the value of a group of trees or woodland may collectively be important

Other factors such as wildlife habitat can strengthen a case but not be sufficient in isolation to justify a TPO.

Pruning overhanging trees

You are permitted to prune back overhanging branches from a tree in a neighbour's property, if the tree is not covered by a TPO or in a conservation area.

We would advise you to check the status of a tree with the owner or  the council before pruning any branches. Any unauthorised works to trees covered by a TPO or in a conservation area carry a large fine.   

If the tree is located within a conservation area, but is not covered by a TPO, a description of works to be carried out needs to submitted.

You will need to submit this to the Tree Preservation Officer before the works are due to start. 

Private property

The care and maintenance of any trees within private property is the responsibility of the landowner or tenant.

Trees not covered by a TPO or conservation area

Any dispute between neighbours regarding trees not covered by a TPO or not within a Conservation Area is considered a civil matter. The council will not intervene at any time.

Council housing tenants

If you live in a council house you are responsible for maintaining the trees in the front and back garden. Please check your tenancy agreement for further information.

Cracks in walls

If you suspect damage such as cracks in walls or surrounding land to a property, is caused by a tree located on the public highway, you should as your first point of call contact our Insurance Department.
