One in five companies operating car fleets intends to reduce the choice of cars they offer to employees, while one in four is planning to extend lease periods, as businesses clamp down on company car polices.

Restrictions have also been imposed on the CO2 emissions of cars - 37% of organisations have now placed a cap – and 15% of companies plan to provide cheaper cars, according to PricewaterhouseCoopers’ Company Car UK report.

Certain types of car are also being subjected to restrictions due to safety concerns.

For instance, 79% of companies have placed restrictions on sports cars and 76% on convertibles.
