Does RM15 4YF flood?

Aveley, Thurrock

Up to Very low likelihood

Properties in RM15 4YF sit in the Environment Agency's Very low flood-likelihood band (worst property). The band is the worst found in the postcode — it describes the land around properties (defence-adjusted, rivers & sea), not any single address, and not today's conditions.

Likelihood bandAnnual chancePropertiesOf which homes
Highgreater than 3.3%00
Medium1% – 3.3%00
Low0.1% – 1%00
Very lowbelow 0.1%50

Over a 25-year mortgage, a property in a very low-likelihood area has less than a 3% chance of flooding at least once.

How much rain falls on RM15 4YF

RM15 4YF gets about 573 mm of rain a year on average (wettest month October, 61 mm; driest March, 34 mm). That is 51% drier than the UK as a whole, which averages 1,163 mm a year.

A thirty-year average for the surrounding area, not a measurement at this address and not a flood risk on its own: a dry area floods when a storm sits over it, and a wet one may drain away perfectly well.

The watercourse nearest RM15 4YF

The nearest watercourse on the river map is an unnamed stream, about 200 m from the centre of RM15 4YF.

A gauge downstream shows water that has already passed this point; one upstream sees it first. Distances along the river are from the point on an unnamed stream nearest the centre of RM15 4YF. From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist. This describes where water goes on the map; it says nothing about flooding at any address. Contains OS data © Crown copyright and database rights 2026.
