Aviva detected more than 18,400 suspect claims worth £233 million across its brands in 2025, including Direct Line, as the UK’s largest insurer reported record levels of claims fraud driven by a significant rise in AI-generated documents, exaggerated motor injury claims and organised ghost broking operations.
The figures — the first to combine Aviva and Direct Line data following Aviva’s acquisition of Direct Line in July 2025 — represent the equivalent of £638,000 of fraud detected every day and underline the scale of fraudulent activity now flowing through the UK personal lines insurance market.
More than 37 years of custodial and suspended sentences were secured for the most serious offences in 2025, with one named case involving two sisters convicted of conspiracy to defraud after orchestrating a staged collision that generated inflated injury and credit hire claims worth £470,000.
The nature of motor fraud is shifting materially. Aviva reports that fraudsters are moving away from staged collisions and towards exaggerated claims for vehicle damage, repair costs, credit hire and injury — a pattern that directly affects the evidential landscape in which PI solicitors operate. The value of detected motor fraud rose 39% in 2025 as high-value exaggeration attempts increased in volume and sophistication. Liability insurance fraud showed a parallel trend, with the value of fraudulent claims rising 32% driven by inflated loss of earnings, rehabilitation costs and injury valuations.
The most significant development for legal practitioners is the growing use of AI-generated imagery and manipulated documents to support false claims. Aviva confirmed it is seeing an increasing number of claims backed by fabricated accident scene photographs and AI-manipulated damage documentation, particularly in motor insurance. Pete Ward, Head of Claims Counter Fraud at Aviva, confirmed the insurer is investing in AI-enabled detection tools supported by human oversight to identify suspicious claims earlier — a counter-escalation that will shape how fraud is evidenced and challenged in PI proceedings.
Professional enablers represent a further pressure point. Aviva identified a growing number of claims involving unscrupulous loss assessors inflating repair costs, contents values and scopes of work in property claims — a category of fraud that engages solicitor professional obligations and regulatory exposure under the Solicitors Regulation Authority’s conduct framework where legal professionals are involved in or adjacent to fraudulent claims handling.
Ghost broking rose 7% year on year with 105,000 fraudulent applications detected in 2025, predominantly targeting younger drivers through social media. Home insurance fraud rose 15%. For PI solicitors, insurers and in-house legal teams, the Aviva data signals that fraud detection technology is becoming more sophisticated on both sides of the claims process — and that the evidential and professional obligations attaching to claims handling will face increasing scrutiny through the remainder of 2026.
