Commencement Notice

What it means in practice

A commencement notice is the building-control notification made before many works begin. PlanningBrief's detailed BCMS dataset is historical, so current notices need source verification.

For PlanningBrief readers, the important point is timing: a planning term usually signals who might need to act next, which documents to check, and whether a project is early intelligence, live tender opportunity, appeal risk or near-site-stage context.

Worked example

Example: a granted housing scheme with a later accepted commencement notice is much closer to mobilisation than a fresh planning application. H&S providers, plant hire, scaffolding and materials suppliers treat this as a hotter signal.
