Flood & hazards in West Bromwich · Environment Agency

In West Bromwich, heavy rain puts more homes at risk than rivers or the sea: 5%, against 0.2%

On the Environment Agency’s maps, which allow for flood defences, “high or medium” means at least a 1 in 100 chance of flooding from rivers or the sea in any year. Hazard risk puts West Bromwich at B−: #19 of 35 in West Midlands.

Hazard risk Grade

West Bromwich grades B− for hazard risk

Flood risk from rivers and the sea, against all UK towns.

Homes at high or medium flood risk (0.2%)Fewer than 51% of UK towns

The share of homes at high or medium risk from rivers and the sea, ranked against every UK town of 1,000 or more: fewer homes at risk is better. Towns with none at high or medium risk are ordered by their share at low risk, so they don’t all share one score. Surface water and radon aren’t graded: they are described below.

The river and sea risk follows the River Tame and the Ford Brook. Surface-water risk is spread across the city, in dips, underpasses and along small streams, which is why more homes are exposed to it.

The Environment Agency’s Risk of Flooding from Rivers and Sea (NaFRA2, June 2026) counts each postcode’s homes by band; the shares weight those postcodes by Census 2021 households. The EA counts include homes built since 2021.

Surface water

Heavy rain puts about 26.4 times as many West Bromwich homes at risk as rivers and the sea do

Surface water is rain that falls faster than drains and the ground can take it. It is mapped separately from rivers and the sea, and it is not in the Hazard risk Grade.

Surface water5%
Rivers and the sea0.2%
0%7%14% of homes

About 2.3% of homes are at high risk of surface-water flooding (a 1 in 30 chance or more each year) and 2.7% at medium risk: roughly 2,000 households. A further 7% face a low risk from surface water. That is more than 69% of UK towns.

Our estimate: every address in the city (ONS NSUL) read on the Environment Agency’s Risk of Flooding from Surface Water map (NaFRA2, 2025), each postcode’s share weighted by its Census 2021 households. Neither agency publishes a count of homes for surface water, so treat it as a guide; one street can differ from the next.

River levels

The River Tame in November 2024 rose to its 5th-highest level since 1990

The highest level each winter (October to September) at the Environment Agency’s Bescot gauge (Walsall), since 1990. The river normally runs between 0.32 m and 1.25 m here.

Radon

Parts of West Bromwich are in radon Affected Areas, up to the 10–30% band

Radon is a natural radioactive gas from the ground; long exposure raises the risk of lung cancer. The atlas gives the chance that a home in each 1 km square is above the UK action level (200 Bq/m³).

85% of West Bromwich’s built-up area is in a radon Affected Area (1% of homes or more above the action level), and 36% in squares of 5% or more, mostly on the north-east side of the city.

The squares are indicative: each takes the highest band found anywhere inside it, so most homes in a coloured square are below it. Only a three-month test in the home gives a real answer.

In a cloudburst
  • Surface water rises in minutes, often with no warning issued: stay out of underpasses and dips.
  • Keep the gullies and drains outside your home clear of leaves.
  • Report a blocked road drain to the council.
Radon
  • Test over three months, in a living room and a bedroom.
  • Above 200 Bq/m³, a small sump and fan usually fixes it.
  • New homes in radon areas are built with protection: basic from 3%, full from 10%.

Before you buy or rent in West Bromwich
  • Check the address on GOV.UK’s long-term flood risk service: it gives rivers and sea and surface water separately.
  • Ask whether the home has flooded or had a flood insurance claim; the TA6 property form asks the seller.
  • Homes built before 2009 can get flood cover through Flood Re, the government-backed scheme; newer homes can’t.
  • Check radon for the address on UKradon.org (a small fee) or ask the seller for a test result.
How to read these numbers

What this data can and can’t tell you

  • Defences are counted. Both agencies’ maps allow for flood defences and the chance they are overtopped or fail, so a town behind a defence scheme can show few homes at high risk and many at low risk.
  • Surface water is our estimate. Neither agency publishes a count of homes at risk from surface water, so we read each address on the map. A flat on a hill and a basement in a dip can share a postcode.
  • One town, many streets. Risk is street by street. Check a specific address on GOV.UK’s long-term flood risk service before you buy or rent.
