Frequently Asked Questions

Is an EV always cheaper than a Petrol car?

Not always. While running costs are lower for EVs, the higher initial purchase price means you need to drive a significant distance over several years to "break even" compared to a cheaper petrol vehicle.

Does this include maintenance costs?

This specific calculator focuses on fuel and purchase costs. Maintenance is generally lower for EVs and higher for Diesel cars, which should be considered separately for a full assessment.
