FLEETS have succeeded in cutting the number of thefts from their vehicles by 37% over the past year, but the cost of the average incident has risen dramatically.

Autoglass' sixth annual car crime survey reveals that attacks on fleet vehicles fell to 316,000 incidents at a cost of £106 million last year, down from £127 million and 499,000 cases during the previous 12 months. But the typical cost of a claim rose 31% to £335, from £255 last year. In addition, drivers lost nearly three working hours sorting out an incident - 15% lost a full working day - costing companies dearly.

The windscreen expert believes fleets have helped themselves by installing tough security measures. Last year fleet vehicles accounted for 25% of thefts from cars, but this year that figure is down to 17%. This, however, has forced thieves to change direction, targeting the high value items carried by fleet drivers or older cars.

The survey coincides with this week's Car Security Week, which is sponsored by Autoglass, which also claims the overall cost of car crime in the UK has soared 22% to £622 million from £509 million, although attacks have fallen from 1,997,000 to 1,858,000.
