Use this application for works to trees subject to a tree preservation order (TPO) and/or notification of proposed tree works within a conservation area.

In conservation areas, notice is required for works to trees that have a trunk diameter of more than 75mm when measured at 1.5m from ground level (or more than 100mm if reducing the number of trees to benefit the growth of other trees).

You have to give us six weeks’ notice before carrying out work on trees which are located in a conservation area but are not yet the subject of a TPO. This gives us an opportunity to consider whether an order should be made to protect the trees.

Before making an application please read the guidance notes Opens in a new window.

• Sketch plan showing location of all trees
• A full clear specification of the works to be carried out

• Any evidence to support your statement of reasons

Carrying out work on your tree

It is good practice to employ a specialist qualified contractor to carry out the work. Work on the highway should be carried out safely and by surgeons qualified to work in accordance with the recommendations in Chapter 8 of the Traffic Signs Manual. The person responsible for the work, or their contractor, should have Public Liability Insurance cover for working on the highway for a value of £5 million.
