Do you drive your own car for business purposes?

If you've answered yes to this question, you're identified in business terms as a 'grey fleet' driver. Did you know that depending on the number of miles travelled, you could save money by hiring a vehicle? And you will have the advantage of driving a car with the latest vehicle technology and avoid further depreciation of your own vehicle.

We have devised the 'Grey Fleet Calculator' below to act as a handy tool for you to use to work out whether a hire car is a more cost effective option for your trip. Some of the fields have been pre-populated with typical values for grey fleet / hire vehicles but feel free to update them with your own specific details for a more accurate calculation.
