When it is required
Why a council asks for this.
Section 38(6) of the Planning and Compulsory Purchase Act 2004 requires an application to be determined in accordance with the development plan unless material considerations indicate otherwise. This is the document that engages with it.
| Required when |
|---|
| Almost every application that is not a bare householder extension |
| Any scheme where the council's validation list asks for a supporting statement |
| Any scheme where the principle of development is arguable |

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.

Often alongside
Documents that usually travel with it.
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.
Submitted after permission is granted, to satisfy the conditions attached to it. Most permissions cannot be built out until these are cleared.

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