What Does High Wycombe's Flood Risk Classification Mean?

Which Postcode Districts Cover High Wycombe?
Each district below is one postcode district that falls inside High Wycombe. The band is the one shared by most of that district's postcodes, so it describes the district rather than a single street — enter a full postcode in the checker for one address. A district can cover more than one town, and the district pages linked from the checker are keyed to the town that holds most of its postcodes.
| Postcode district | Postcodes here | Rivers and sea band | Surface water addresses |
|---|---|---|---|
| HP13 | 782 | High | 4,271 |
| HP11 | 440 | High | 3,523 |
| HP12 | 440 | High | 2,262 |
| HP10 | 2 | Not mapped — no rivers-and-sea band covers this district | not published for this district |
"Not mapped" is not "no risk". It means no rivers-and-sea band covers that district in the source — surface water can still flood it, and both Camden and Islington flooded from surface water in July 2021 while carrying no mapped rivers-and-sea band.
