Official record · dataset-bounded
No conservation area, Article 4 direction or tree preservation zone covering this property is recorded on planning.data.gov.uk. That national dataset does not yet have complete coverage, so this is not confirmation that none applies.
Door Number shows planning designations, not an application history. For both and the definitive position, check the London Borough of Croydon planning register.

This address is not shown within Flood Zone 2 or 3 on the Environment Agency's Flood Map for Planning (Rivers and Sea). That map covers rivers and the sea only — not surface-water or groundwater flooding — so this is not a statement that the property is not at risk.
