Cars must be fitted with laminated side glass to qualify for five stars in the New Car Security Rating (NCSR) scheme launched at the end of July. The rating relates to how difficult it is to break into different car models.

The scheme is the result of two years’ research by the Vehicle Crime Reduction Action Team (VCRAT).

The team was set up following government calls in 1999 to cut car crime by 30% in five years. The NCSR scheme is expected to help achieve this target.

Vehicle crime prevention officer of the Metropolitan Police, Detective Inspector Keith Brayne, said: “There are around two million thefts from cars every year.

“In 20 years’ time, with this type of secure glass installed in all cars, theft from cars could be a thing of the past.”
