Reigate Flood Risk
Reigate has no mapped rivers-and-sea flood risk: neither the national risk assessment nor the planning Flood Zone map covers it. That is not a statement that Reigate cannot flood — this figure covers rivers and the sea only, and surface water flooding is not included. The nearest gauge is 2.5 km away.
Reigate has 24,224 residents and 10,405 homes. Ranked equal 3078 of 7,114 — the places where the national risk assessment maps no rivers-and-sea exposure for any home, so the position is a tie rather than a low score.

Absence of a record is not evidence that a place has never flooded — the Environment Agency states that a lack of coverage does not mean an area has never flooded.
What Does Reigate's Flood Risk Classification Mean?
0% of postcodes in Reigate sit in Flood Zone 3, the planning band for land with a 1% or greater annual chance of river flooding or 0.5% or greater of sea flooding — and the map that draws it deliberately ignores flood defences.
The flood risk band for rivers and the sea is not mapped here, which means the national assessment finds no rivers-and-sea exposure for Reigate's homes rather than a low amount of it. That is a statement about rivers and the sea only: surface water flooding is not included, and it is the larger source nationally.
Which Postcode Districts Cover Reigate?
Each district below is one postcode district that falls inside Reigate. 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 |
|---|---|---|---|
| RH2 | 642 | High | 1,562 |
| RH1 | 21 | Low | 24 |
| RH3 | 1 | 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.
