Willis, a business of WTW, has launched a new parametric insurance solution that activates automatically when a red weather warning is issued by the UK Met Office or Met Éireann, the Irish National Meteorological Service.
Developed in collaboration with Swiss Re Corporate Solutions, which will act as the insurer, the policy represents a new approach to weather-related risk transfer.
Unpredictable and disruptive
Weather remains one of the most unpredictable and disruptive risks to lives, property and businesses. National meteorological offices use colour-coded warning systems - yellow, amber/orange and red - to alert the public and organisations about severe weather and its potential impacts. Red weather warnings are reserved for the most extreme conditions that present significant risk to life, widespread property damage and major disruption to travel.
Recent examples highlighted the severity of these events. In January 2025, Storm Éowyn triggered red warnings across the UK and Ireland. Winds peaked at 114mph, causing widespread property damage, power outages and transport disruption. Insurance claims in Ireland alone exceeded €240 million, much of it from commercial property losses.
Traditional insurance policies typically respond to physical damage from storms or floods but do not cover the costs of pre-emptive measures that organisations often take when warnings are issued. Willis’ new policy addresses this gap by linking coverage directly to the weather warning itself rather than the weather event or resulting damage. In effect, the forecast becomes the trigger.
This design has particular relevance for sectors such as hospitality, where event cancellations or voluntary closures during red warnings lead to significant revenue losses, even if the forecasted conditions do not fully materialise. The policy provides a pre-agreed payout that can be used to cover lost income and operational costs, offering faster claims settlement and greater flexibility in use of proceeds.
A shift in risk transfer models
For insurers, the development points to a broader shift in risk transfer models.
Parametric solutions have been gaining traction as clients look for clarity and speed in claims handling, especially in areas where traditional indemnity cover is difficult to structure. By tying cover to weather warnings, Willis and Swiss Re Corporate Solutions are expanding the application of parametrics beyond agriculture and catastrophe bonds, into day-to-day business interruption and operational risks.
The policy also reflects how insurers are adapting to climate change by recognising the indirect but material costs businesses incur when reacting to extreme weather. Market observers expect growing demand for such solutions across leisure, transport and retail, particularly as UK and Irish weather events become more volatile and costly.
For reinsurers, parametric triggers also create opportunities to diversify exposures and manage accumulation risk in a more predictable way.
The launch underlines a wider trend in the European market, where parametric products are moving from niche solutions to mainstream risk management tools. With climate volatility increasing, insurers and reinsurers are positioning these products as a complement to traditional cover, offering clients both resilience and speed of recovery.
