These documents provide analysis of the numbers of properties within areas at risk of coastal erosion taken from the National Coastal Erosion Risk Mapping 2024 product. We use them in Environment Agency publications and reports; and to answer queries.
We use the National Coastal Erosion Risk Mapping 2024 and the National Receptor Dataset (NRD) 2023 to provide a breakdown of numbers of properties at risk of erosion within England and local authorities.
The spreadsheet provides the following summary information:
• Number of residential and non-residential properties in areas at risk from coastal erosion
Further explanations about the information presented in the spreadsheet such as the management and climate scenarios, timeframes covered by the assessment and how numbers are calculated are presented in the first tab of the spreadsheet.
The raw values are presented and should be rounded to an appropriate level of precision for the geographical area you choose to use the data for.
INFORMATION WARNINGS:
The data and associated information are intended for guidance only - it cannot provide details for individual properties.
The data shows areas of land likely to be at erosion risk but does not show the precise future position of the shoreline.
The information is provided as best estimates based upon historic data termed ‘present day’ and, the higher central and upper end sea level rise climate change allowances representing UKCP18 RCP8.5 sea level rise projections. Unlike the previous NCERM, data ranges based on percentiles are not provided.
The NCERM information considers the predominant risk at the coast, although flooding and erosion processes are often linked, and data on erosion of foreshore features are, in general, not included.
Some parts of the coast have complex geology causing ground instability. Unlike the previous NCERM, data on these zones of ground instability are provided. More detailed information on these areas may be available from local authorities Attribution statement: © Environment Agency copyright and/or database right 2025. All rights reserved.
