The Environment Agency has released an updated National Flood Risk Assessment (NaFRA) and Coastal Erosion Risk Map (NCERM).
These assessments reveal that 6.3 million properties in England are at risk of flooding or erosion, with climate change expected to exacerbate the situation in the coming decades.
What the Data Reveals
The updated assessments provide a comprehensive view of flood and coastal erosion risks across England, leveraging cutting-edge methods and the latest climate projections. Key findings include:
- 6.3 million properties in England are in areas at risk of flooding from rivers, the sea, or surface water.
- Surface water flooding poses the greatest threat, impacting 4.6 million properties, a 43% increase compared to previous estimates due to improved modeling techniques.
- 2.4 million properties are at risk of flooding from rivers and the sea, with an 88% rise in properties classified as having a high probability of flooding.
The data also highlights significant future risks. With climate change factored in, the number of properties at risk could rise to 8 million by mid-century, meaning nearly one in four homes in England will face flooding concerns.
Coastal Erosion and Climate Change
The updated National Coastal Erosion Risk Map reveals stark changes along England’s coastlines. Currently, 3,500 properties are projected to be at risk of erosion by 2055, increasing to 10,100 by 2100. This data underscores the urgency of managing shoreline changes effectively.
Julie Foley, Director of Flood Risk Strategy at the Environment Agency, stated:
“Our updated assessment shows there are 6.3 million properties in England in areas at risk of flooding. When we account for the latest climate projections, one in four properties could be at risk by mid-century.”
How the Assessments Were Conducted
The new assessments utilize advanced software that integrates local flood risk models from both the Environment Agency and local authorities. For the first time, these models incorporate the UK’s latest climate projections, providing a unified national picture of current and future risks.
Hannah Bartram, representing ADEPT (Association of Directors of Environment, Planning and Transport), highlighted the importance of these updates:
“More detailed flood and coastal risk information, which takes climate change into account, is essential for local authorities to plan effectively and protect communities.”
This data is critical for decision-makers, developers, and communities to plan resilience strategies and allocate resources where risks are highest.
A Snapshot of Flood and Coastal Risk
Risk Type |
Current Properties Affected |
Projected Properties Affected (2050s) |
|---|---|---|
| Surface Water Flooding | 4.6 million | Increasing significantly |
| Rivers and Sea Flooding | 2.4 million | Greater than 3 million |
| Coastal Erosion | 3,500 | 10,100 by 2100 |
This snapshot highlights the increasing severity of flood risks and the growing importance of resilience planning.
Building Resilience for the Future
In response to these findings, the Environment Agency is working to bolster national flood defenses and improve public access to vital information.
A rolling programme of data updates will ensure that local communities and policymakers are equipped with the most accurate flood and erosion risk insights.
The initiatives include:
- £1 billion investment this year in new and improved flood defenses.
- Updated digital services such as the Check Your Long-Term Flood Risk tool, available from early 2025.
- The creation of a flood and coastal investment programme that prioritizes areas with the greatest current and future risks.
These measures form part of the government’s £200 million flood and coastal innovation programmes, which aim to explore new approaches to improving resilience in a changing climate.
Why It Matters
Flooding and coastal erosion are pressing challenges for the UK, especially in light of climate change. As Julie Foley noted, having the best available information enables policymakers, planners, and communities to adapt effectively to these risks.
Understanding vulnerabilities in homes, businesses and infrastructure helps create a resilient future through collaborative planning and action.
