Running Costs
If you’re looking for the most cost-effective company car, don’t forget the role that fuel economy should play in your decision.
A company car driver will often focus only on the cost of benefit-in-kind taxation. However, this might lead to a higher overall cost when private fuel costs are taken into account.
The below example compares a petrol and a diesel model with the same P11D value.
Although the petrol car offers lower benefit-in-kind taxation, when we consider the cost of private mileage, diesel is the lower cost option.
