Is the UK heatwave changing your Home Insurance risk?
Is the UK heatwave changing your Home Insurance risk?
Recent heatwaves across the UK aren't just breaking temperature records – they're also changing the way insurers assess the risk of subsidence, particularly for older homes and properties built on clay-rich soils.
With temperatures already reaching the mid-30s earlier than usual this year, insurers are seeing heat-related claims become a much more common part of the UK's insurance landscape.
Why are heatwaves increasing the risk of subsidence?
Prolonged periods of hot, dry weather can cause the ground beneath a property to shrink, particularly in areas with clay soil. As the ground moves, foundations can shift, leading to cracks in walls, uneven floors and other signs of subsidence.
While subsidence has always been a consideration for insurers, repeated heatwaves mean it's becoming more difficult to predict which properties may be affected.
James Nicholson, Chief Claims Officer at Zurich UK, recently commented that:
"Heat is no longer an outlier – it's becoming part of the baseline risk profile in the UK."

Older and non-standard homes face greater challenges
The impact is particularly significant for older properties and homes constructed using non-standard materials. These buildings can be more susceptible to structural movement and often require specialist repair methods if damage occurs.
Not only can these properties be more vulnerable, but the cost of repairs has also increased significantly due to higher material costs, labour shortages and the need for specialist restoration work.
What does this mean for homeowners?
As insurers continue to review the impact of climate change and extreme weather, it's becoming increasingly important to ensure your home insurance provides the right level of protection.
Whether you own a modern home, a period property or a listed building, having suitable cover in place can make a significant difference should subsidence or structural movement occur.
If you've noticed new cracks appearing after periods of hot weather, it's also worth seeking advice before the problem becomes more serious.
