If you wish to protect a tree in your area, write to the Planning Authority stating your reasons, and include a map to aid identification. An immediate, temporary (six month) TPO can be put in place by the Local Planning Authority. The Authority would then inform neighbours and interested parties. Any objections must be received within 28 days. After six months, the temporary TPO could be confirmed and made permanent, or allowed to lapse. Local residents have the chance to raise objections in that time.
Exceptions can be made to the need for permission or notice of tree works in the case of emergency, but it is better to inform the Council first. Fines can be up to £20,000 for unauthorised interference with a protected tree. Certain exceptions exist for commercial orchards, certain works done by utility companies, and in specific legal situations.
Note that TPOs do not protect trees from felling where a new development has been granted planning permission by the Planning Authority, if the tree’s presence would impede the implementation of that planning permission.
