A man sentenced to 28 months in prison for fabricating home insurance claims involving stolen Lego sets has been identified as one of last year's most prominent insurance fraudsters, according to the Association of British Insurers (ABI). The case exemplifies a troubling trend: while the number of detected fraudulent claims fell slightly, the average value of each fraudulent claim surged to £14,300, the second-highest level ever recorded.
The ABI's latest fraud data, published on 6 October 2026, reveals that insurers uncovered £1.34bn in fraudulent claims during 2025—a 14% jump from the £1.18bn detected in 2024. However, the total number of detected fraudulent claims decreased slightly to 93,900, down 2.7% compared with the previous year.
Mark Allen, head of fraud and financial crime at the ABI, warned that fraudsters are becoming more ambitious in their targeting.
Although the rate of detected insurance fraud fell slightly last year, our data shows that fraudsters are targeting much bigger payouts. As emerging technologies such as AI become more widely available, fraudsters will continue to look for new ways to exploit them.
Det Ch Insp Simon Klust, head of the Insurance Fraud Enforcement Department (IFED) at the City of London Police, emphasised the broader impact of such crimes.
Insurance fraud is not a victimless crime and those who commit it increase the cost of premiums for honest customers.He noted that the 250 cases detected daily by the ABI in 2025 were
unfortunately likely to be just the tip of the iceberg.
How did the Lego fraudster operate?
One of the most notable cases involved a man prosecuted by IFED who submitted false claims to Axa Insurance during 2021 and 2022. Beyond the high-value Lego sets he claimed had been stolen, his fraudulent submissions also included MacBooks, televisions, gaming consoles and fishing equipment. When IFED officers searched his home in 2023, they discovered collectible Lego sets matching those he had reported as stolen displayed openly in his living room. In addition to his prison sentence, he was ordered to repay £14,000—the amount he had fraudulently claimed.
What other major fraud cases emerged?
The ABI highlighted several other significant cases from 2025. One man received a 20-month prison sentence for manipulating women he encountered on dating sites into participating in staged car crashes. Another fraudster was sentenced to four and a half years in prison after submitting over £300,000 in false travel medical emergency insurance claims using multiple fake identities and forged documents.
Which types of insurance are most vulnerable to fraud?
Motor insurance remains the sector most affected by fraudulent claims, accounting for 55% of all detected scam cases. The most prevalent form of insurance fraud is exaggerated loss, where claimants deliberately attempt to inflate the true value of a legitimate claim. The ABI identified 26,900 such cases in 2025.
The ABI's detected-fraud statistics cover cases resulting in a conviction or caution, or where evidence of fraud is compelling, and exclude some paid exaggerated-injury claims and claims withdrawn during routine handling. This methodology means the true scale of insurance fraud may be substantially larger than the recorded figures suggest.
How does 2025 compare with previous years?
The 2025 figures represent a significant shift in fraud patterns. In 2024, insurers detected more than 98,400 fraudulent claims worth £1.16bn, while preventing an estimated 684,800 fraudulent insurance applications. The increase in average claim value despite a decrease in the number of detected claims suggests that fraudsters are becoming more selective and targeting larger payouts, potentially reflecting greater sophistication in their schemes.
