Coastal erosion risk intelligence

Rising sea levels are increasing the risk of coastal erosion. At the same time, mitigation measures are in place to slow the effect. The rate of future coastal erosion will depend on both of these factors, and to understand what that might look like, you need intelligence that accounts for both.

Sea levels are rising and coastal storms are becoming more frequent and severe. These factors are causing coastal erosion to increase. But coastal erosion depends on more than simply how the climate changes – it will be directly influenced by how shoreline management plans (SMPs) can slow this effect.

These factors make decision-making around coastal erosion complicated and dynamic. To understand exactly how your properties might be affected over time, you need comprehensive intelligence that combines climate data with SMP delivery scenarios.

Twinn’s Coastal Erosion Risk Intelligence combines geomorphological modelling with policies like SMPs to show how coastal physics and future intervention will affect erosion risk. As a result, you get the property-level probability of erosion up to the year 2100, with the first year of hazards highlighted across multiple climate change scenarios.

Harness Twinn’s coastal erosion data to:

Improve long-term asset viability
through strategic site selection and intelligence of where mitigating actions will have the most impact
Enable appropriate pricing
of loans and insurance policies involving coastal properties, and provide evidence of coastal erosion exposure to support financing and investment decisions 
Gain more detailed understanding
of how risks from coastal erosion evolve over time and under different climate change scenarios
Assess where adaptation is required
to protect properties and reduce business interruption and asset depreciation

Coastal erosion data for every business

Our coastal erosion intelligence tool integrates address data from Ordnance Survey with National Coastal Erosion Risk Map (NCERM) and National Coastal Change Assessment (NCCA) data. This means we can estimate the likelihood of coastal erosion for individual properties year-by-year.

It covers the length and breadth of Great Britain and is designed to give multiple different sectors the intelligence they need.

  • Financial institutions and real estate businesses can evaluate the long-term viability of properties near coastlines to make more informed lending and investment decisions.
  • Insurers can incorporate property-level coastal erosion exposure into underwriting, portfolio assessment, and pricing decisions.
  • Businesses with coastal facilities, such as ports or factories, can use data to inform adaptation strategies, supporting long-term operational resilience.
  • Every client gets property-level data that supports transparent, quantitative disclosure to support climate-risk reporting and disclosure requirements.
