Urban Floods Threaten 839,000 Homes
29 Apr
Summary
- 839,000 urban homes face high surface-water flood risk.
- Social housing tenants are most vulnerable to flood costs.
- Flooding in urban areas is a rapidly growing threat.
Eight in 10 homes at high risk of flooding in England are now located in urban areas, a stark increase driven by extreme rainfall, ageing infrastructure, and rapid urbanisation. Analysis indicates that 839,000 homes in towns and cities are now classified as being at high risk of surface-water flooding, a figure that has tripled since 2018.
Social housing tenants are disproportionately affected by the financial consequences of these floods. These residents are more exposed, less protected, and least able to absorb the costs of water damage, often due to a lack of contents insurance. Areas like Thurrock, Basildon, and parts of London have the highest proportion of at-risk homes and social housing residents.
The Environment Agency defines a home as high risk if it has at least a one in 30 chance of flooding annually. Projections suggest that the number of properties at risk could treble over the next 50 years if current trends continue. Housing associations are investing in protective measures, but the National Housing Federation stresses the need for a national strategy to address this escalating national concern.
