Could this become an HMO?

Most small-HMO conversions live or die on one fact: whether an Article 4 direction has withdrawn the automatic change-of-use right at that address. We check the national polygon data, then show you how your council actually decides HMO applications.

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.
