Average diesel prices at UK forecourts have reached a record 199.18p per litre, surpassing the previous peak of 199.09p in June 2022. The article links the rise to the continuing Iran conflict and uncertainty over the Strait of Hormuz, warning that higher fuel costs could soon push diesel above £2 a litre and feed through to prices across the economy.

The RAC estimates that filling an average family car with diesel now costs almost £110, about £31 more than at the start of the US-Iran conflict in February. Petrol has also risen to an average 174.13p a litre, around 41p higher, making a full tank nearly £96. The government has extended its 5p fuel-duty cut to year-end; the RAC is urging further help, as reversing the cut as planned could add another 5p per litre by spring.
