When it is required
Why a council asks for this.
Sections 197 to 214 of the Town and Country Planning Act 1990, and section 211 for conservation-area notifications.
This is a supporting statement only. The statutory tree works application form, and the tree-by-tree schedule of works that normally accompanies it, must be filed separately through the Planning Portal. Complex cases usually also need a BS 5837 survey from an arboriculturist. You are told this in the quote step, before you pay.
| Required when |
|---|
| The tree carries a Tree Preservation Order |
| The tree stands in a conservation area, where six weeks' notice is required |

Why it exists
Documents answer constraints.
A council does not ask for this because it likes paperwork. It asks because something on or near your site triggers it, and the appraisal will tell you whether yours is triggered before you pay for anything.

About the Tree Works.
Why does Wren not produce the whole tree works application?
Often alongside
Documents that usually travel with it.
The main written case for a planning application. It describes the site and the proposal, then argues the scheme against the policies your council will actually decide it under.
Identifies the heritage assets a scheme affects, explains what makes each of them significant, and assesses honestly what your proposal would do to that significance.
Proves that something you have built, or intend to build, is lawful and needs no planning permission. It is a certificate of fact, not a judgement of merit.
For development that is already permitted in principle, but where the council still gets a say on specific matters. Larger extensions and office-to-residential conversions are the common ones.

The appraisal names the route, lists the documents that route requires, and prices the set before you commit to anything.
