Counts are read from planning.data.gov.uk and refreshed daily. A zero or dash means the council has not yet published that dataset to the national index — not that the designation doesn’t exist on the ground. We show what we found and tell you what we didn’t. We never infer a restriction — or the absence of one — from missing data.
