Tree Preservation Order (TPO)

Works to trees protected under a Tree Preservation Order (TPO) and/or works to trees in a conservation area

Before making an application to us, if you wish to undertake works to a protected tree or it is in a conservation area, we recommend you seek advice from an appropriately qualified professional, either a tree surgeon or an arboricultural consultant.

Information about choosing a suitable person can be obtained from the Arboricultural Association.

To submit an application for works to trees protected under a Tree Preservation Order (TPO) or in a Conservation Area, you can apply online at the National Planning Portal. Alternatively, you can complete the relevant application form below:

The application must include:

  • A plan which identifies the tree(s) to which the application applies;
  • Exact details of the works for which consent is sought – e.g. crown thin by x% (See tree surgery terminology below);
  • Statement of the reasons form making the application;
  • Appropriate evidence (e.g. if the proposal is to fell a tree because of structural damage to a property, reports on soil type, foundation depth and evidence of tree roots around the building or if the application related to tree health or safety, a report from a qualified person).

Any submission that does not include the above information will not be registered, and you will be required to provide the relevant additional information before the proposals can be considered.

In determining an application, we will take account the impact works would have on the tree’s visual contributions to the area and to good arboricultural practice.

Tree surgery terminology – what do we mean?

  • Crown - the part of the tree, which is above ground level, apart from the main stem;
  • Crown thinning - the removal of selected branches throughout the crown to reduce its density by a given percentage, without reducing the tree’s overall shape;
  • Crown lifting - the removal of lower branches to increase the clearance above ground level to provide access around the tree or prevent obstruction for vehicles using the highway;
  • Crown reduction - reducing the height and spread of the crown by a given amount;
  • Pollarding - the removal of the whole crown to a given point on the main stem.
  • Dead wood or crown cleaning - the removal of dead, dying, damaged or diseased branches, back to sound wood, for reasons of safety and appearance.
