Tackling the rising tide of weather-related claims: How is insurance evolving?

Back-to-back storms have left the UK grappling with catastrophic flooding, extensive damage, and widespread disruption. Storm Bert, which swept through the country in November, devastated communities, particularly in Wales, submerging roads, homes, and businesses. Barely two weeks later, Storm Darragh tore across the UK, leaving a trail of destruction in its wake, exacerbating the strain on flood defences and emergency response systems.

The scale of the damage has displaced thousands of families and overwhelmed businesses, and the effects of severe flooding continue to be felt in many parts of the country. Welsh First Minister Eluned Morgan described the impact of Storm Bert as “absolutely devastating.”

These storms have brought not just physical destruction but also a sharp focus on the critical role of insurance in helping individuals and businesses recover, while highlighting the urgent need for resilience against the escalating threat of climate-driven disasters.

How are climate disasters transforming the insurance industry?

For households and businesses, the surge in weather-related claims paints a challenging picture — higher premiums, stricter policies, and an urgent need to adapt. The big question is: how will these increasingly frequent climate disasters reshape the insurance landscape? Will insurance become a lifeline for resilience, or a growing burden in the face of escalating climate risk?

One thing we know: Storm Bert is far from an isolated event. Experts, including those at the Met Office, warn that climate change is driving more frequent and severe weather events. In 2022 alone, insurers across Europe faced over €10 billion in weather-related claims, with the UK bearing a significant portion of that cost. And the financial burden isn’t limited to insurers — individuals and businesses are increasingly feeling the pinch of higher premiums and limited coverage options.

To manage these increasing risks, insurers are shifting from traditional models of risk assessment towards more data-driven, proactive strategies.

Insurers are investing heavily in data analytics to better predict and price risks. This includes using real-time weather data to create dynamic policies that adjust coverage and premiums based on changing risk levels. However, the sector is also grappling with regulatory challenges, particularly around pricing fairness and transparency.

“The insurance sector is at the forefront of managing climate risks, but it’s clear we must innovate to keep pace with this new reality,” David Otton, a spokesperson for the Association of British Insurers (ABI), recently stated.

What this means for businesses

For businesses, Storm Bert is a wake-up call to revisit their insurance policies and risk management strategies. Standard commercial policies may no longer be enough. Businesses need to evaluate whether they have adequate coverage for flood damage, business interruption, and long-term operational recovery.

Emerging trends such as parametric insurance offer promising solutions. Unlike traditional policies, parametric insurance pays out a pre-agreed sum based on the occurrence of a specific event (e.g., a storm with a certain wind speed or rainfall level), enabling businesses to receive funds faster.

Insurers are increasingly incentivising businesses to invest in resilience measures, such as flood defences or sustainable building materials. These initiatives not only lower premiums but also mitigate the long-term costs of damage.

Lloyd’s of London is leading initiatives to integrate sustainable drainage systems (SuDS) into urban developments. These systems redirect excess rainwater into storage or natural water bodies, preventing overflow during storms. Measures like these not only protect individual properties but also help reduce the strain on local drainage infrastructure, mitigating city-wide flooding risks.

Collaboration is a key trend. Insurers are partnering with governments and environmental organisations to fund large-scale resilience projects that are not only good for society but also reduce claims costs in the long run.

What this means for individuals

For individuals, Storm Bert highlights the critical need for comprehensive home and property insurance, but of course affordability is becoming a significant challenge. The surge in claims is leading to higher premiums, particularly in high-risk flood zones.

Innovative solutions such as community risk pooling are gaining traction. This involves communities coming together to share resources and risks, making insurance more accessible and cost-effective. Additionally, the government’s Flood Re scheme continues to play a vital role in keeping insurance affordable for homeowners in high-risk areas.

Technology is also reshaping the claims process for individuals. Mobile apps now enable policyholders to report damage and receive assessments quickly, while drones are increasingly used to survey large-scale damage efficiently.

Coming in 2025: Redefining Insurance

To explore these innovations and developments, ITN Business is launching Redefining Insurance, a new programme airing at the Insurtech Insights Europe Conference on 19-20 March 2025.

Presented by Lukwesa Burak, the programme will dive into innovations like AI-powered risk management, climate resilience strategies, and how insurers are navigating evolving regulations. Thought leaders from Insurtech UK, GFIA, and Insurance Europe will share insights on how the industry is adapting to provide smarter, more sustainable solutions for a rapidly changing world.
