Last summer saw a significant shift in the cost of powering cars and vans, across all vehicle sectors, from one particular source of power.

There’s not much difference if you have a petrol or diesel vehicle, as the spring spike in petrol was evened out by a subsequent fall, while diesel prices dropped steadily, but not enough to cause a major change in the pence-per-mile costs, as these figures show.

The 4p drop in public charging hasn’t resulted in pence-per-mile figures for electric cars and vans changing a great deal either.

But there has been a big shift on the home front. It is now even more cost-effective to use domestic energy for business mileage: most vehicle sectors have seen a reduction of around 1.5p per mile on their running costs.
