As supply uncertainty continues, diesel is now up more than 33p per litre since the start of the Iran conflict, according to the RAC, while petrol has risen by around 16p per litre.
To put that into context, diesel has jumped from roughly 142ppl to 175ppl, while petrol has moved from about 133ppl to 149ppl. In real terms, that’s a noticeable hit. For drivers covering regular mileage, it means higher weekly fill-ups, while fleets are already seeing costs stack up across multiple vehicles.
So far, the UK hasn’t followed countries like Ireland and Spain, which have cut fuel duty and VAT to ease pressure. Instead, fuel duty here remains frozen until September, before planned increases later in the year.
The bigger issue is uncertainty. Research suggests UK drivers and businesses have already paid an extra £307 million at the pumps since the crisis began, and even if oil prices fall, it can take weeks for that to filter through.
For more on this, we covered rising fuel costs and the small changes fleets can make to reduce consumption in last week’s This Week in Fleet LinkedIn Live.

Even when pump prices are out of your control, simple shifts like smoother driving, reducing unnecessary mileage and encouraging car sharing can make a noticeable difference to overall fleet spend.
