Allianz UK identified fraudulent claims totalling almost £174m in 2025, up by more than 10% on the £157m it sniffed out the previous year. During 2025, the carrier recorded an 84% increase in staged accidents, in which two vehicles crash into each other on purpose. It also noted a 61% rise in contrived accidents, where a fraudster crashes into an innocent party and then fabricates damage or injury.

In addition, Allianz UK said it had seen fraudsters balloon casualty claims. In these cases, once a claim has been accepted for a modest sum it is then exaggerated by including fake additional injuries. The carrier said ghost broking also remained a major threat.

Ben Fletcher, director of fraud and financial crime at Allianz UK, said: “Fraudsters are continually changing their tactics and we need to match their efforts with greater speed and agility than ever before. We’re working more closely than ever with a wide range of suppliers, industry organisations and the police to catch the fraudsters, and our 2025 results indicates that our efforts are working.

“We do all we can to protect our genuine customers and businesses against the harm of fraud and make it a hostile environment for anyone seeking to commit fraud against us. We are resolute in our determination to identify and defend against any type of fraud and use a variety of methods to detect it such as voice analytics and machine learning tools.”
