By Effie Foxtrot · 22 May 2026
In brief: Previsico, WTW, Descartes, and Generali have launched a parametric flood insurance solution for UK racecourses using IoT sensors to trigger automatic payouts for high-risk properties.
| Target Portfolio | 16 racecourses |
|---|---|
| Projected Flood Costs | £3.6 billion annually by 2050 |
| Exposed Properties | 300,000 UK commercial properties |

Quick Summary
Previsico, WTW, Descartes, and Generali have launched a parametric flood insurance solution for UK racecourses. By using real-time IoT sensors to trigger automatic payouts based on water depth, the partnership provides immediate liquidity for high-risk commercial properties previously considered uninsurable by traditional markets.
How Does Parametric Flood Insurance Solve Coverage Gaps?
Here is how Previsico solves the protection gap for high-risk commercial properties. Traditional indemnity insurance often fails venues on floodplains due to prohibitive deductibles or exclusions. This new model utilizes parametric flood insurance to bypass the traditional claims process entirely. When Previsico’s IoT sensors detect water reaching a pre-defined trigger depth, a payout is automatically initiated without the need for a loss adjuster.
- Immediate liquidity provided via automated data-driven triggers.
- Objective payout scaling based on maximum recorded water height.
- Proactive risk management through early warning alerts for operational teams.
By focusing on verifiable environmental data rather than physical damage assessments, the solution ensures that businesses like Arena Racing Company (ARC) can maintain financial resilience against climate-related risks that were once deemed uninsurable.
What Results Has This Technology Delivered for Racecourses?
The initial deployment at Royal Windsor Racecourse demonstrates a successful blueprint for the wider sports and leisure sector. Historically, this venue on the River Thames struggled to secure viable flood coverage. The new system is now being scaled across 16 UK racecourses, including high-exposure sites in Worcester and Southwell. This is critical as UK flood costs are projected to hit £3.6 billion annually by 2050.
- 16 racecourses targeted for portfolio-wide protection.
- 50% projected increase in UK flood-related costs by 2050.
- 300,000 commercial properties in the UK currently exposed to flood risk.
This parametric flood insurance approach allows Arena Racing Company to move equipment to higher ground before flooding occurs, effectively reducing potential loss while securing a guaranteed payout structure if water levels breach specific thresholds.
FF NEWS TAKE:
This partnership is a masterclass in using parametric flood insurance to fix a broken market. By integrating Previsico's hardware directly into the underwriting workflow, WTW and Descartes have turned "uninsurable" assets into a manageable data problem. This moves the needle because it proves that IoT-driven insurance isn't just a gimmick—it is a fundamental necessity for climate adaptation in the commercial property sector.
Frequently asked questions
How does parametric flood insurance work for commercial properties?
Parametric flood insurance uses real-time IoT sensors to monitor water levels at specific locations. When water reaches a pre-defined trigger depth, a payout is automatically initiated. Unlike traditional insurance, it does not require a physical damage assessment or a loss adjuster visit, providing immediate liquidity to the policyholder.
Which companies are providing the new flood insurance for UK racecourses?
The solution is a collaboration between flood intelligence specialist Previsico, broker WTW (Willis), specialist underwriter Descartes Underwriting, and insurer Generali. The first deployment is at Royal Windsor Racecourse, owned by Arena Racing Company (ARC).
Why is this parametric solution important for the sports and leisure sector?
Many sports venues, such as racecourses, are located on floodplains and have historically been deemed uninsurable or faced impractical deductibles. This parametric model provides a viable path to coverage for high-risk assets by using objective data triggers rather than traditional loss adjustment.
