How Could Hotter Summers Affect Insurance in the Future?
How Could Hotter Summers Affect Insurance in the Future?
The British weather has always had a reputation for being unpredictable.
One day can bring blazing sunshine, while the next delivers heavy rain and thunderstorms. However, as periods of unusually high temperatures appear to be occurring more frequently, insurers are beginning to consider how a warmer climate could influence the risks faced by homeowners, motorists and travellers.
Flooding has traditionally dominated conversations around climate-related insurance claims, but prolonged periods of heat can create a range of challenges that are often overlooked.
Hot Weather Can Put Homes Under Pressure
Many homes across the UK were built to cope with cold, damp winters rather than extended periods of extreme heat.
When temperatures remain high for prolonged periods, building materials naturally expand and contract, roofing materials can deteriorate more quickly and timber may dry out and shift.
Extended dry weather can also affect underground pipework and water systems through changes in ground conditions.
One of the most significant concerns is subsidence.
As clay soils dry out during long periods without rainfall, they shrink, increasing the likelihood of movement beneath building foundations.
Following the record-breaking heat of 2022, the Association of British Insurers reported record levels of subsidence claims, demonstrating how expensive prolonged hot weather can become for homeowners.
Vehicles Also Feel the Heat
Modern vehicles are designed to operate in demanding conditions, but sustained high temperatures still increase the workload on many components.
Cooling systems, tyres, batteries and air-conditioning units all face greater demands during hot weather, while road surfaces themselves can soften under intense heat and heavy traffic.
Electric vehicles introduce additional considerations.
Although battery-powered vehicles generally cope well in warmer conditions, effective battery temperature management becomes increasingly important during periods of extreme heat.
Most of these issues relate to vehicle maintenance rather than insurance claims, but they can contribute to breakdowns, delays and, in some circumstances, accidents.
Travel Disruption May Become More Common
Travel insurance has traditionally focused on medical emergencies, cancellations and lost baggage.
However, prolonged heat is beginning to influence travel in different ways.
Wildfires affecting southern Europe, transport disruption caused by extreme temperatures and temporary closures of popular attractions have become increasingly familiar during recent summers.
Just as insurers routinely account for storms and natural disasters, prolonged heat is becoming another factor that could influence future travel claims.
How Insurers Respond to Changing Weather
Insurance is based on understanding and managing risk.
As weather patterns evolve and certain events become more frequent, insurers continually update their pricing models and risk assessments to reflect new information.
That doesn't necessarily mean insurance premiums will rise dramatically.
The insurance industry continually analyses vast amounts of claims data to improve its understanding of emerging risks and develop products that reflect changing circumstances.
Global reinsurers—the organisations that provide insurance for insurance companies—have consistently identified climate-related risks as one of the biggest long-term issues facing the industry.
What Could the Future Look Like?
One of the more interesting questions is how changing temperatures might influence everyday behaviour.
For example:
Will more people work from home during prolonged periods of hot weather?
Could demand for home cooling systems continue to increase?
Will more outdoor leisure activities create new insurance considerations?
Could infrastructure face greater strain during increasingly frequent heatwaves?
While nobody has definitive answers, these are exactly the kinds of long-term trends insurers monitor as they prepare for future risks.
Preparing for a Changing Climate
No one knows exactly what future British summers will bring.
Periods of extreme heat are likely to sit alongside heavy rainfall and rapidly changing weather, just as they always have.
What is becoming increasingly apparent is that insurers, governments and property owners are paying much closer attention to the long-term effects of climate change and how those risks continue to evolve.
Motor-Vision Insurance follows developments across the insurance industry as new risks emerge, helping motorists, homeowners and travellers understand how changing conditions could influence the protection they need.
The weather may change from week to week, but understanding how those changes develop over years and decades will remain an important part of modern insurance.
