Fraud figures up 18% on 2012.
The value of fraudulent insurance claims uncovered by insurers rose to a record £1.3bn in 2013, up 18% on the previous year, according to figures from the Association of British Insurers (ABI).
Insurers detected a total of 118,500 bogus or exaggerated insurance claims, equivalent to 2,279 a week, the ABI's research revealed.
The average fraud detected across all types of insurance products was £10,813.
Fraudulent motor insurance claims were the most expensive and common, with the number of dishonest claims at 59,900 claims up 34% on 2012 and their value at £811m, up 32%.
The number and value of property insurance frauds fell compared with 2012, with 35,000 frauds detected, or a 38% decrease. The value of these frauds was £137m.
The trade body noted that since 2007, the value of dishonest general insurance claims detected has more than doubled, with the number detected up 30% over the same period.
Aidan Kerr, the ABI's assistant director, head of fraud, said: "The vast majority of customers are honest and rightly expect tough action against the fraudsters.
"Insurance fraud is not a victimless crime, which is why the industry invests £200m a year in fraud detection, including funding the Insurance Fraud Enforcement Department, and developing the Insurance Fraud Register, a central database of known insurance cheats.
"The more that is done to crack down on the dishonest, the quicker and more effectively insurers can deal with the claims from the honest majority."
