Property And Home Claims.

Water Is The Frequency Driver

Property claims are dominated by two causes, and the second one behaves very differently from the first. In the United States, wind and hail accounted for 42.5% of homeowners claims in 2023 and water damage and freezing for 22.6%, the second largest cause. Over the five years to 2023 water damage and freezing ran at a frequency of 1.50 claims per 100 policies with an average severity of $15,400, against 2.80 per 100 for wind and hail. (ISO, a Verisk Analytics business, reproduced by the Insurance Information Institute. The category includes mould damage where covered, and excludes tenant and condominium policies. US dollars.)

The contrast that defines the line is with fire. Fire and lightning ran at a frequency of 0.23 per 100 policies and an average severity of $88,170 over the same period. (ISO, reproduced by the Insurance Information Institute.) Fire is rare and catastrophic; water is common and moderate. Roughly one insured home in sixty has a water damage or freezing claim each year. Volume is where the operational cost of property claims sits, and water supplies the volume.

Severity on that high-frequency category is rising faster than frequency. Non-weather water loss cost fell 6.4% and frequency fell 7.8% between 2024 and 2025, while severity rose 2.5% year on year and 63.16% between 2019 and 2025, attributed to inflation and rising material and labour costs in remediating water damage. Across all perils, severity reached an all-time high in 2025, up 25.9% on 2024 and 93.2% against 2019, while frequency fell 23.8% year on year. (LexisNexis Risk Solutions, 2026 U.S. Home Insurance Trends Report, 22 July 2026.)

The United Kingdom position runs the same way and is reported in cash rather than frequency. Property insurance payouts reached £6.1 billion in 2025, the highest annual total on record, of which £3.4 billion was paid on more than 560,000 home insurance claims at an average of £6,000, up 15% year on year. Weather-related property claims, a category that expressly includes burst and frozen pipes and escape of water, took £1.2 billion, up 14%. Average domestic flood payouts reached £30,000, up 60%; domestic subsidence payouts reached £307 million, the highest on record. (Association of British Insurers, 17 February 2026. Pounds sterling.) In the first quarter of 2026, home claims of £846 million were paid at an average household claim of £6,340, the highest on record and up 20% year on year, with the average weather-related home claim at £6,040, up 38% from £4,390. (Association of British Insurers, 6 May 2026.)

Why Property Claims Run Long

The structural diagnosis is the same as in motor, and the evidence for it is unusually direct because an ombudsman has measured it.

In a sample of buildings insurance cases where final decisions had been issued, agents were involved in 80%, and of those 75% were upheld, against an already high general uphold rate of 57% for buildings insurance claim delay complaints. The published conclusion: the more third-party agents involved in a claim, the more likely it is that difficulties will emerge. The parties named are loss adjusters and surveyors. Complaint drivers in the quarter were claim decline at 41%, claim delay at 23% and claim value at 8%, on 2,001 buildings insurance complaints, the highest in any three-month period and up 13% year on year. (Financial Ombudsman Service, 29 August 2024. Uphold-rate data covers 1 April 2023 to 21 March 2024.) The same source names supply chain issues, insurers struggling to find contractors and source materials, and the rising cost of building materials and contractors among the causes, and describes consumers as locked in a confusing chain of communication with no one party taking responsibility.

Cycle time moves accordingly. The average claim cycle time from filing to finished repairs reached 32.4 days, the longest since the study began in 2008, with an average of more than 44 days from first notice of loss to final payment, also the longest on record. Satisfaction fell 167 points on a 1,000-point scale between a claim completed within ten days and one where repairs took more than 31 days, and 82% of customers interacted with their insurer often via their non-preferred communication channel. (J.D. Power, 2025 U.S. Property Claims Satisfaction Study, 18 March 2025, 5,178 homeowners who filed a claim in the prior nine months.) The following year both measures improved: 29.6 days to complete a repair, down 2.8 days, and 40.7 days to final payment, down 3.4 days. (J.D. Power, 2026 U.S. Property Claims Satisfaction Study, 17 March 2026, 5,093 respondents.)

The most direct evidence that property claims are reworked rather than simply slow comes from a regulator that publishes closed-claim data. Across 732,390 closed claims in 2022, reopened-claim rates ran at 51.0% for non-hurricane windstorm and hail, 48.5% for other water and 43.7% for accidental discharge or overflow of water or steam, against 33.6% for fire or lightning and 33.0% for hurricane. Policyholders took an average of 50 days to report a claim and insurers an average of 60 days to close one. (Florida Office of Insurance Regulation, Residential Property Claims and Litigation Report, January 2024, on calendar year 2022 closed claims from 180 companies.)

Severity escalates sharply with elapsed time in the same dataset. On accidental discharge or overflow of water or steam, non-litigated average indemnity ran at $9,038 for claims closed within 61 days, $17,851 at 61 to 180 days, $31,816 at 181 to 365 days and $57,479 beyond a year, with average loss adjustment expense rising from $1,131 to $6,273 across the same bands. (Florida Office of Insurance Regulation, January 2024. US dollars. The direction is consistent across every peril in the table. This is correlation: complex claims take longer as well as costing more.)

The Contractor And Restoration Supply Chain

A motor claim depends on a repair network with finite throughput. A property claim depends on the general construction labour market, which is larger, less organised around insurance work, and under its own pressure.

The United States construction industry needs 349,000 net new workers in 2026 to keep pace with demand, rising to 456,000 in 2027, against 439,000 forecast for 2025 and more than half a million in each of the two preceding years. A majority of new worker demand in 2026 is attributable to retirement rather than to increased demand for construction services, with the published warning that failing to attract them will worsen shortages and place further upward pressure on labour costs. (Associated Builders and Contractors, 28 January 2026, from its own model. Forecast, not outturn.)

Materials moved at the same time. Overall construction input prices rose 2.6% in a single month and 9.6% year on year in May 2026, with copper wire and cable up 24.2%, iron and steel up 7.0%, hot-rolled steel bars, plates and structural shapes up 10.0%, and truck freight transportation prices up 17.3%. Average hourly earnings for construction production and non-supervisory workers rose 5.0% against 3.6% for the private sector overall, and contractor backlog stood at 8.8 months, the highest in ten. (Associated Builders and Contractors analysis of Bureau of Labor Statistics Producer Price Index data, and Associated General Contractors, as reported by Engineering News-Record, 11 June 2026. US dollars.)

Backlog is the operative number for an insurer. A contractor with 8.8 months of committed work does not price an insurance repair as marginal revenue, and does not schedule it ahead of work already booked.

Catastrophe Surge

The property line carries a failure mode motor does not: demand arriving in a single day, across one geography, at many multiples of normal volume.

Global insured natural catastrophe losses reached $107 billion in 2025 against $141 billion in 2024 and a previous ten-year average of $111 billion, on global economic losses of $220 billion, of which 49% was insured, the highest share on record. Secondary perils — wildfire, severe convective storm, flood, winter storm outside Europe and drought — accounted for 92% of global insured losses, a record; the Los Angeles wildfires alone produced $40 billion, the largest insured wildfire loss on record. Long-term growth in insured losses runs at 5% to 7% a year, with more than 80% of the long-term increase in weather-related insured losses explained by exposure growth. (Swiss Re Institute, sigma 01/2026, 19 March 2026. US dollars.) The publisher's own reading of the below-trend 2025 figure is that it results from favourable variability rather than any easing of underlying risk.

National series show the volatility better than global ones. Canadian severe weather insured losses reached CA$2.4 billion in 2025, the tenth costliest year on record, against CA$8.5 billion in 2024; cumulative insured losses from catastrophic weather and wildfire rose from CA$14 billion in the decade to 2015 to CA$37 billion in the decade to 2025, inflation-adjusted, with the average number of claims nearly doubling over the same span. (Insurance Bureau of Canada, 20 January 2026, using loss estimates licensed from CatIQ. Canadian dollars.) Australian extreme weather produced AU$3.49 billion from 264,000 claims across five declared events in 2025, against AU$581 million in 2024 and AU$2.35 billion in 2023, with ex-Tropical Cyclone Alfred alone generating 132,000 claims and AU$1.5 billion. (Insurance Council of Australia, 23 January 2026. Australian dollars.) A six-fold swing between consecutive years is a capacity planning problem before it is an underwriting one.

What surge does to unit cost has a published benchmark. A general industry benchmark for demand surge is an increase in costs of between 20% and 30% after a disaster, varying widely by event, material and location. (Milliman, 10 January 2022. The benchmark predates current construction cost inflation; the mechanism is the durable part.) The same analysis names four drivers, one of which is specific to insurance: a shortage of claims adjusters, in which property adjusters receive a much larger caseload than usual and see claims that are more severe and more complex than standard, raising the cost of handling claims and increasing delays, which are themselves associated with increased claim costs over time. Material shortages resolve relatively quickly once transport is restored, while shortages of contractors or claims personnel have longer-lasting effects.

Contractor backlog in a region hit by a major hurricane rose 1.2 months against 0.1 months in all other regions, with an average difference across the disasters studied of almost one month. (Milliman, 10 January 2022, citing the Associated Builders and Contractors Construction Backlog Indicator.)

Fraud Patterns Specific To The Line

Property fraud is dominated by a pattern that barely exists in motor: not the fabricated event, but the real event with an inflated bill.

In the United Kingdom, 18,700 detected fraudulent property insurance claims worth £189 million were recorded in 2024, with volume 11% higher than 2023, within a total of £1.16 billion across 98,400 detected fraudulent general insurance claims. Exaggerated loss — a deliberate attempt to increase the cost of a claim beyond its true value — was the most common type detected at £466 million, up 10%. (Association of British Insurers, 17 November 2025, on 2024 detected-fraud data. Pounds sterling.)

In the United States, property and casualty fraud excluding auto theft and workers' compensation was estimated at $45 billion a year, within a total annual cost of insurance fraud across all lines of $308.6 billion. (Coalition Against Insurance Fraud, 26 August 2022, analysis by the Colorado State University Global White Collar Crime Task Force. US dollars. The study states that better data collection is needed to quantify the actual cost, and replaced a figure that had stood unrevised for 27 years.) Cross-checks cited in the same study include a Federal Bureau of Investigation estimate of $40 billion for non-health insurance fraud and an Insurance Information Institute estimate of $38 billion for property and casualty fraud.

The cost of contested property claims is measurable where a regulator has published it. Average loss adjustment expense ran at $9,934 on litigated claims against $1,576 on non-litigated claims, a multiple of 6.3. Statewide, 9.8% of closed claims were litigated, rising to 27.5% in three southern counties. Litigation rates by peril were 11.61% for accidental discharge or overflow of water or steam, 11.56% for other water and 10.29% for non-hurricane windstorm and hail, against 5.08% for hurricane and 1.91% for fire or lightning. That jurisdiction accounted for 14.9% of nationwide property claims in 2022 and 70.9% of the nation's litigation. (Florida Office of Insurance Regulation, January 2024. US dollars. The data predates the 2022 and 2023 legislative reforms, and the publisher states that other metrics indicate a strengthening market following them.)

The peril pattern in that table is the finding worth carrying. Water and roof-adjacent losses are the litigated ones; fire, the most severe peril, is not. Disputes cluster where causation is arguable and the evidence degrades quickly, which is where property and motor claims have most in common. The motor equivalent is set out here.

The Shared Structure

A property claim and a motor claim are different products with different perils, different supply chains and different regulators. Underneath, they fail in the same way. Several independent parties each hold a fragment of the file. Information is re-collected at every hand-off. The supply chain that performs the repair is outside the insurer's control and under its own capacity constraints. Cost accrues while the file waits, and the probability of dispute rises with elapsed time.

Where the lines separate is in the shape of demand. Motor arrives at a steady rate. Property arrives in bursts that exceed the capacity of every party in the chain simultaneously, and the cost of that is measured in the same unit as everything else on this site: days.
