Flood Loss Prevention: Previsico and Mitigrate Target Insurers' Rising Flood Bills
Previsico and Mitigrate have agreed a partnership that joins real-time flood forecasting to property-level prevention intelligence, giving insurers across the UK, the Nordics and the rest of Europe a route to flood loss prevention rather than after-the-event claims handling. Announced on 10 November 2026, the tie-up pairs Previsico's hyperlocal forecasts, which tell insurers where and when surface water will arrive, with Mitigrate's analysis of which specific buildings are most exposed and which costed measures would cut the damage.
The commercial logic is straightforward. Previsico already tells an insurer that a flood is coming to a given street. On its own, that warning does not say which of the properties on that street will flood first, how badly, or what a surveyor should recommend to limit the loss. Mitigrate's layer answers those questions at the level of the individual building, which turns a forecast into a prioritised list of interventions. Victor Nekhay, insurance lead at Previsico, framed the combination as the step from knowing where and when flooding will hit to knowing which properties to protect and which measures will reduce the loss.
What does the partnership give insurers?
The two companies are targeting three decisions that insurers already make, with the aim of letting them act before water arrives rather than after.
In underwriting, the pitch is to combine location-specific forecasts with building-level vulnerability data so that prevention spending is directed where it returns the most. In risk engineering, the same two data sets are used to focus surveys and prevention advice on the properties where both the forecast and the structural vulnerability point to the highest potential loss, rather than spreading survey capacity thinly. In claims, the partners point to intervention before and after an event, with build-back-better repairs that reduce the chance of the same property flooding and claiming again.
That last point maps directly onto a scheme insurers already operate. Flood Re, the government-backed reinsurance pool, introduced its own Build Back Better programme in 2022, funding resilient repairs so that reinstated homes are less exposed next time. A partnership that puts costed resilience measures in front of claims teams is pushing on a door the industry has already opened.
Why are insurers moving from flood warnings to flood prevention now?
Because the claims numbers have stopped being manageable on a pay-and-repair basis. The Association of British Insurers reported that weather-related claims for homes and possessions reached a record £585 million in 2024, up £127 million, or 28 per cent, on 2023 and more than triple the 2022 figure. The pressure has carried into recent quarters: the ABI recorded a record £226 million in weather-related claims in the first quarter of 2025 alone, against a previous quarterly record of £67 million.
For property insurers, that has translated into sustained underwriting losses. EY figures cited by the ABI show that in 2023, for every £1 of home insurance premium received, insurers paid out £1.18 in claims, part of a run of consecutive years in which property books lost money. Individual flood events are expensive to settle: insurer estimates put the average cost of repairing a flooded home at around £36,000. Preventing even a share of those losses changes the economics of the book.
The structural pressure sits behind all of this. Flood Re was launched in 2016 to keep cover affordable for high-risk homes, with nearly 290,000 policies ceded to the pool in the year to March 2024. It is a transitional measure, legally required to manage the shift to risk-reflective pricing, and it is due to end in 2039. When it does, insurers will price flood risk on the actual exposure of each property, which makes any technology that lowers that exposure, building by building, commercially relevant well before the deadline. Prevention is the lever that keeps a high-risk property insurable at a price its owner will pay.
How do Previsico and Mitigrate fit together?
The two companies come at the problem from opposite ends. Previsico is a surface water flood forecasting specialist, spun out of Loughborough University in 2019 on the back of more than two decades of hydrological research led by Professor Dapeng Yu, and backed by Foresight Group. Its live, street-level forecasts are already used by insurers including Zurich, Liberty and Generali, and the company runs offices in Loughborough, London, the United States and Hong Kong. Its strength is timing and location: knowing, hours ahead, where surface water will pool.
Mitigrate approaches from the building side. The Oslo climate insurtech, founded in 2021, analyses property-level flood vulnerability and recommends the specific, costed measures most likely to reduce expected losses. The company says its platform covers more than 50 million buildings across the Nordics, the UK, France and Germany. It has drawn outside validation along the way, including a strategic investment from Lloyd's in 2025 and a live deployment with Norwegian insurer Gjensidige. Laurent Feuilleaubois, chief executive of Mitigrate, has consistently argued for loss prevention over higher premiums as the way to keep flood risk insurable, and he positions the Previsico partnership as letting insurers act on both the warning and the fix.
Neither company has disclosed commercial terms, a launch insurer, or a timetable for the first joint deployments, so the near-term test is whether the combined proposition converts into named insurer contracts across the three markets the partners have identified.
Why This Matters to FinanceX Readers
For insurers and reinsurers, this is a data point on whether pre-loss intelligence can be priced and underwritten as a mitigation tool rather than sold as an add-on. The through-line from both companies is keeping flood risk insurable, which is precisely the problem the market inherits as Flood Re winds down towards 2039 and household flood cover moves to risk-reflective pricing. Forecasting tells an underwriter the water is coming; property-level prevention tells them which pounds spent now will cut the claim later.
For investors tracking climate adaptation, the partnership is a signal that the insurtech conversation is shifting from measuring risk to actively reducing it, where the return is a smaller loss ratio rather than a better dashboard.
