Does CR2 flood?

Yes — parts of the CR2 district carry real flood risk: 47 of its 74 at-risk postcodes reach the Environment Agency's High likelihood band. The CR2 postcode district covers South Croydon, Waddon, Purley Oaks & Riddlesdown, close to Beddington, South Norwood, Carshalton, and surrounding villages in parts of Greater London and Surrey.

74 postcodes in the CR2 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 47 high, 12 medium, 15 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).

Rivers and flooding history near CR2

The rivers that matter here, each monitored live on FloodRadar:

157 official flood warnings and alerts have been raised within ~10 km of the district's centre since 2006 (8 at warning level or above), most recently 27 August 2026. Warnings cover flood areas, not individual addresses.

No recorded flood extent is mapped near this district's centre. No recorded outline near the district means no flood was mapped here, which is not evidence none happened: the Environment Agency mapped only some floods, mapping effort rose sharply after about 2000, and surface-water flooding is largely absent from this record.
