Does IG11 0NF flood?

Barking, Greater London

Up to Low likelihood

Properties in IG11 0NF sit in the Environment Agency's 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%1616
Very lowbelow 0.1%00

Over a 25-year mortgage, a property in a low-likelihood area has a 2–22% chance of flooding at least once.

How much rain falls on IG11 0NF

IG11 0NF gets about 578 mm of rain a year on average (wettest month October, 63 mm; driest March, 34 mm). That is 50% 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 IG11 0NF

The nearest watercourse on the river map is Mayes Brook, about 210 m from the centre of IG11 0NF. It flows into Warpools Reach (River Roding) about 330 m downstream.

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 Mayes Brook nearest the centre of IG11 0NF. 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.
