- UK homeowners are reporting widespread subsidence damage, including large diagonal cracks and sticking doors, after two record-hot summers weakened foundations, particularly in clay-rich areas.
- Admiral, Hastings, and Axa have seen a surge in subsidence claims, with Hastings reporting a 140% increase in August 2026 compared to the previous year and Axa calling it a 'surge year'.
- Association of British Insurers (ABI) data shows the average subsidence claim hit a record £20,000 between April and June 2026, up over £2,000 from the previous year, with £72m paid out.
- British Geological Survey warns that under a worst-case climate scenario, 11% of UK homes — more than 4.2 million — could be at risk of subsidence by 2070 due to shrinking soils.
- Timothy Farewell of MapleSky attributes rising structural damage to 'differential movement' caused by uneven soil drying, often exacerbated by trees drawing moisture from one side of a property.
- Shaune Worrall of the British Insurance Brokers’ Association warns of a 'double surge' in claims as 2025 cases overlap with 2026 filings, stretching insurer capacity and delaying repairs.
- Rachel Hogarth Smith and other homeowners are delaying insurance claims due to fears of higher premiums or future coverage denials, even as structural engineers advise waiting for spring repairs.
Why it matters: Insurers are facing higher payouts and longer claim durations, with subsidence claims now averaging £20,000 and often lasting years. Homeowners risk financial penalties for filing, creating a catch-22: delay repairs and risk worsening damage, or claim and jeopardize future insurability.
