New ABI research has revealed that fraudulent claims on motor and household insurance cost insurers and their honest policyholders £20m per week.
The most common reason given by fraudsters to justify cheating was "most people do it" (23%).
Other reasons given were "it doesn't harm anyone personally" (22%), "insurers can afford it" (20%), and "you are unlikely to get caught" (16%).
The ABI's Head of Financial Crime Prevention said: "Life is about to get even tougher for insurance cheats."
"While insurance fraudsters come in all shapes and sizes, this research will help insurers have a clearer picture of what drives insurance fraud."
