Surge in UK Homeowners’ Subsidence Claims After Record-Hot Summer

The summer of 2026 was the hottest on record in the United Kingdom, according to the Met Office. Scientists say hotter, drier conditions cause soil shrinkage that can drag down foundations, especially in older houses. The British Geological Survey identifies London, Essex, Kent and a stretch from Oxford to the Wash on the east coast as the most vulnerable zones.

Hastings Direct, which insures 4.8 million homes and vehicles, reported a near 140 % increase in subsidence claims for August compared with the same month a year earlier, marking an all-time high. The average subsidence claim between April and June reached £20,000, about £2,000 higher than the previous year, according to the Association of British Insurers (ABI). Insurers paid out £72 million for domestic subsidence claims in the same period, up from £60 million a year earlier. Overall payouts for 2025 rose to roughly £297 million, a 6 % increase from the prior year and 89 % higher than in 2022, the ABI reported.

Charlie Inwood, the ABI’s general insurance policy adviser, warned that the elevated claim volumes are likely to persist through the autumn unless sustained rainfall restores soil moisture. Aviva, which completed a £3.7 billion acquisition of Direct Line in July, confirmed a recent rise in subsidence claims and said the trend will continue without significant rainfall. Chief executive Amanda Blanc said Aviva is reviewing its reserves, pricing models and exposure management for subsidence. Axa described the year as a “surge year” for weather-related damage but stopped short of labeling it a record. Adam Holland, head of retail underwriting, fraud and pricing governance for Axa’s UK arm, highlighted the climate-change implications of the record heat.
