After a temporary decline in 2024, lightning-related homeowners' insurance losses surged in 2025, reflecting both increased claim activity and a sharp rise in claim severity.
According to the Insurance Information Institute (Triple-I), insurers paid an estimated $1.65 billion in lightning-related homeowners' claims in 2025; a 59.4% increase from $1.04 billion the previous year. The number of claims rose 11.6% to 61,986, while the average cost per claim increased 42.8% to $26,616. Compared to 2017, the average cost per claim has increased by nearly 147%.
The disparity between claim frequency and overall loss growth is notable. Claim counts increased modestly, but severity accelerated significantly, accounting for most of the increase in insured losses. The trend reflects broader inflationary pressures affecting building materials, labor and replacement costs, as well as the growing concentration of sophisticated electronics and interconnected systems within homes.
Today's homes often contain dozens of devices vulnerable to lightning-induced power surges, including smart-home technologies, security systems, entertainment equipment, HVAC controls and connected appliances. As a result, a single lightning event can generate multiple losses within the same property, increasing both claim complexity and settlement costs.
Florida recorded the highest number of lightning claims in 2025, while Texas reported the highest average claim value, exceeding $60,000.
The Triple-I's findings reinforce the value of loss-prevention initiatives, including homeowner education and surge protection devices. As weather-related losses continue to challenge underwriting profitability, lightning remains a peril that warrants close attention despite its relatively low frequency.
