Do I need planning permission?
Answered against the actual designations at your postcode — Article 4 directions, conservation areas, green belt — from national polygon data, plus your council's measured decision record. Not a generic flowchart.
What this is: data intelligence computed from public planning records — application registers, decision notices, appeal decision letters and national designation polygons (planning.data.gov.uk). Every figure states its source and sample. What this is not: formal planning advice, and designation boundaries are checked against the postcode centroid, not your exact property line. For certainty on your specific case, speak to a chartered planning consultant — our specialist directory can help.
