FAQ

Validation checklist questions

Short answers to what land teams ask us before a demo.

What is a planning application validation checklist?

It is the list of documents a council requires before it registers an application. A national baseline applies everywhere, and each council adds a local list. LandBuyer AI shows both for your authority.

How does LandBuyer AI build the checklist?

From the proposal on your site: dwelling count, floor area, application type and use class. It then adds triggers found by the other checks, such as former industrial or landfill use nearby.

Can I rely on it to validate an application?

No. It is for guidance. Confirm requirements with the planning authority before submission, because some triggers need professional judgement, such as heritage setting and ecological impact zones.

Does it say whether a viability assessment is needed?

Yes. It states whether one is required and the policy reference. On Kew Yard it is not required unless viability is challenged, under paragraph 58 of the national planning policy framework.
