As record-setting wildfires sweep across the UK, the insurance industry is under mounting pressure to adapt pricing, coverage, and claims practices in response to a threat that is no longer confined to hotter, drier climates.
2025 is already the worst year on record for wildfires in the UK, with incidents rising by over 700 percent compared to the same period in 2024. For insurers and loss adjusters, this surge marks a turning point.
"We've probably more than doubled the area burned compared to previous peak years," said Glyn Brookes-Humphrey (pictured), director of commercial property operations at Woodgate & Clark. "And while property losses have been limited so far, that may be more luck than design."
Once seen as a fringe environmental concern, wildfires are now being treated as an emerging systemic risk. Climate shifts, including drier springs, hotter summers, and wetter winters, are creating a dangerous fuel cycle that accelerates fire spread.
"Wildfires are no longer rare in the UK. Spring has become a peak wildfire season," said Caroline Elliott-Grey of Lexis Nexis Risk Solutions. "We expect more vegetation growth during wet winters, which then dries out during record-hot summers. That cycle creates the perfect conditions for large-scale fires."
The implications go beyond property. Wildfires are now considered a threat to energy infrastructure and the stability of the national grid. Elliott-Grey noted that insurers will need to evolve wildfire models to account for cascading failures across power and utility networks.
Unlike flood, where historical data and mapping allow for more predictable underwriting, wildfires present a unique challenge. The spontaneous nature of ignition and the scarcity of long-term data make risk mapping difficult.
"Traditional underwriting methods don't work with wildfire," said Brookes-Humphrey. "Insurers are going to have to rely on high-resolution mapping, AI, and complex modelling to stay ahead."
New tools such as satellite-derived risk indicators and real-time exposure visualisation are beginning to support more dynamic underwriting. According to Elliott-Grey, data products like the LexisNexis Risk Wildfire Indicator allow insurers to segment risk based on fire history, vegetation proximity, and distance from fire stations - all critical inputs at the point of quote.
As wildfire risk becomes more granular and location-specific, rural and edge-of-urban areas are likely to face higher premiums or restricted coverage. Heritage and timber-frame properties, common in older UK housing stock, add another layer of exposure.
The claims implications are also distinct. Wildfires often lead to total loss scenarios with limited warning, unlike floods or storms where mitigation is possible.
"Fires tend to destroy everything, including documents. We can’t expect policyholders to have receipts or evidence for every item lost," said Brookes-Humphrey. "Adjusters need to apply more pragmatic, empathetic approaches."
The human impact is profound. Emotional trauma from fire loss may be more acute than flood damage, especially when entire streets are affected. Loss adjusting firms are beginning to invest in soft-skills training and fire behaviour education to better support affected policyholders.
Technology also plays a growing role. Drones and satellite imagery are being deployed to assess damage in areas that may remain inaccessible for days. Speed of response and flexibility in documentation requirements are becoming essential capabilities for adjusters in wildfire-prone areas.

SIDEBAR - Broker Briefing: 3 Things to Know About UK Wildfire Risk
2025 has already seen a 700% increase in wildfire incidents. Risk is no longer seasonal or limited to remote areas – urban fringe zones are increasingly exposed.
Insurers are shifting to satellite data and AI-powered modelling to price wildfire risk. Expect changes in premiums and exclusions, especially for rural or heritage properties.
Wildfires often result in total losses with limited evidence. Adjusters are preparing for more pragmatic assessments - and brokers should prepare clients accordingly.
While catastrophic urban fires have not yet occurred in the UK, experts agree the risk is rising, and planning must begin now. That includes reassessing building practices, especially developments that bridge rural and urban areas.
"We could be building on land that previously acted as a fire break," Brookes-Humphrey said. "There’s a real need for planners and insurers to consider wildfire in development risk assessments, much like flood zones."
For insurers, collaboration with the energy sector and government will be key to managing future risks. Sharing real-time data and investing in early warning systems can help mitigate losses and accelerate recovery.
"This isn’t just about claims anymore," Elliott-Grey said. "It's about anticipating the risk and building resilience before the fire starts."
As wildfire seasons lengthen and intensify, the UK insurance market faces a test of adaptability, one that will shape its approach to climate-related risk for decades to come.
